Efficacy and prognostic analysis of carbon nanotracers combined with the da Vinci robot in the treatment of esophageal cancer.

Traditional methods cannot clearly visualize esophageal cancer (EC) tumor contours and metastases, which limits the clinical application of da Vinci robot-assisted surgery. To investigate the efficacy of the da Vinci robot in combination with nanocarbon lymph node tracers in radical surgery of EC. In total, 104 patients with early-stage EC who were admitted to Liuzhou worker's Hospital from January 2020 to June 2023 were enrolled. The patients were assigned to an observation group (n = 52), which underwent da Vinci robot-assisted minimally invasive esophagectomy (RAMIE) with the intraoperative use of nanocarbon tracers, and a control group (n = 52), which underwent traditional surgery treatment. The operation time, intraoperative blood loss, postoperative drainage tube indwelling time, hospital stay, number of lymph nodes dissected, incidence of complications, and long-term curative effects were comparatively analyzed. The postoperative stress response C-reactive protein (CRP), cortisol, epinephrine (E) and inflammatory response interleukin (IL)-6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α) were evaluated. Compared with the control group, the observation group had significantly lower postoperative CRP, cortisol, and E levels (P < 0.05) with a milder inflammatory response, as indicated by lower IL-6, IL-10, and TNF-α levels (P < 0.05). Patients who underwent RAMIE had less intraoperative blood loss and shorter operation times and hospital stays than those who underwent traditional surgery. The average number of dissected lymph nodes, time of lymph node dissection, and mean smallest lymph node diameter were all significantly lower in the observation group (P < 0.05). The rate of postoperative complications was 5.77% in the observation group, significantly lower than the 15.38% observed in the control group. Furthermore, the lymphatic metastasis rate, reoperation rate, and 12- and 24-month cumulative mortality in the observation group were 1.92%, 0%, 0%, and 0%, respectively, all of which were significantly lower than those in the control group (P < 0.05). The treatment of EC using the da Vinci robot combined with nanocarbon lymph node tracers can achieve good surgical outcomes and demonstrates promising clinical applications.

Perioperative complications of middle cerebral artery occlusion in rats alleviated by human umbilical cord mesenchymal stem cells.

For acute ischemic stroke treatment, the limitations of treatment methods and the high incidence of perioperative complications seriously affect the survival rate and postoperative recovery of patients. Human umbilical cord mesenchymal stem cells (hucMSCs) have multi-directional differentiation potential and immune regulation function, which is a potential cell therapy. The present investigation involved developing a model of cerebral ischemia-reperfusion injury by thrombectomy after middle cerebral artery occlusion (MCAO) for 90min in rats and utilizing comprehensive multi-system evaluation methods, including the detection of brain tissue ischemia, postoperative survival rate, neurological score, anesthesia recovery monitoring, pain evaluation, stress response, and postoperative pulmonary complications, to elucidate the curative effect of tail vein injection of hucMSCs on MCAO's perioperative complications. Based on our research, it has been determined that hucMSCs treatment can reduce the volume of brain tissue ischemia, promote the recovery of neurological function, and improve the postoperative survival rate of MCAO in rats. At the same time, hucMSCs treatment can prolong the time of anesthesia recovery, relieve the occurrence of delirium during anesthesia recovery, and also have a good control effect on postoperative weight loss, facial pain expression, and lung injury. It can also reduce postoperative stress response by regulating blood glucose and serum levels of stress-related proteins including TNF-α, IL-6, CRP, NE, cortisol, β-endorphin, and IL-10, and ultimately promote the recovery of MCAO's perioperative complications.

Ultrasound-guided serratus anterior plane block enhances postoperative analgesia and recovery in thoracoscopic surgery.

The serratus anterior muscle, located in the lateral aspect of the thorax, plays a crucial role in shoulder movement and stability. Thoracoscopic surgery, while minimally invasive, often results in significant postoperative pain, complicating patient recovery and potentially extending hospital stays. Traditional anesthesia methods may not adequately address this pain, leading to increased complications such as agitation due to inadequate pain management. To evaluate the application value of ultrasound-guided serratus anterior plane block (SAPB) in patients undergoing thoracoscopic surgery, focusing on its effects on postoperative analgesia and rehabilitation. Eighty patients undergoing thoracoscopic surgery between August 2021 and December 2022 were randomly divided into two groups: An observation group receiving ultrasound-guided SAPB and a control group receiving standard care without SAPB. Both groups underwent general anesthesia and were monitored for blood pressure, heart rate (HR), oxygen saturation, and pulse. The primary outcomes measured included mean arterial pressure (MAP), HR, postoperative visual analogue scale (VAS) scores for pain, supplemental analgesic use, and incidence of agitation. The observation group showed significantly lower cortisol and glucose concentrations at various time points post-operation compared to the control group, indicating reduced stress responses. Moreover, MAP and HR levels were lower in the observation group during and after surgery. VAS scores were significantly lower in the observation group at 1 h, 4 h, 6 h, and 12 h post-surgery, and the rates of analgesic supplementation and agitation were significantly reduced compared to the control group. Ultrasound-guided SAPB significantly improves postoperative analgesia and reduces agitation in patients undergoing thoracoscopic surgery. This technique stabilizes perioperative vital signs, decreases the need for supplemental analgesics, and minimizes postoperative pain and stress responses, underscoring its high application value in enhancing patient recovery and rehabilitation post-thoracoscopy.

Safety and Efficacy of Combined Dexmedetomidine and Bupivacaine versus Bupivacaine Alone in Caudal Block in Pediatric Patients Undergoing Lower Abdominal Surgery

Abstract Background Lower abdominal surgeries are one of the most frequently performed surgical procedures in the pediatric population. Using optimal analgesic regimen provide safe and effective analgesia, reduce postoperative stress response and accelerate recovery from surgery. Regional anesthetic techniques are commonly used to facilitate pain control in pediatric surgical procedures. The most commonly used techniques in pediatrics is caudal block. Objective To evaluate the analgesic effect of dexmedetomidine when given caudally as an adjuvant to caudal block vs bupivacaine alone in caudal block for children undergoing lower abdominal surgeries. Methods The study was conducted on 88 randomly chosen patients in Ain Shams University Hospitals after approval of the medical ethical committee. Patients were divided randomly into two groups; each group consisted of 44 patients. After preoperative assessment and obtaining baseline vital data, all patients received general anesthesia. Group BD who would receive caudal dexmedetomidine and Group B who would receive caudal block with Bupivacaine. Results There was a highly statically significance between groups according to time to first analgesic requirement (hrs). This table show statically significance difference between groups according to number of paracetamol doses in first 24h. While a statically significant difference between the two groups according to PACERO score. The sedation score was higher in group BD compared to group B. Also a statically significance difference between two groups according to FLACC scale at 8h and 12h. The duration of adequate analgesia (FLACC pain score 4 or less) was significantly higher in group BD compare to group B. Conclusion Dexmedetomidine 1 mcg/kg, when used as an adjuvant to caudal anesthesia, can significantly prolong the duration of postoperative analgesia. It is better than bupivacaine alone in caudal block at similar doses in controlling postoperative pain.

Ultrasound-Guided Pudendal Nerve Block versus Caudal Block for Post-Operative Analgesia in Penile Surgeries in Children

Abstract Background Penile surgeries as hypospadias, urethroplasty and circumcision are of the most frequently performed surgical procedures in the pediatric male population. Using optimal analgesic regimen provide safe and effective analgesia, reduce postoperative stress response and accelerate recovery from surgery. This study was to compare the effectiveness and safety of ultrasound (US) guided pudendal nerve block (PNB) versus caudal block (CB) for postoperative analgesia in pediatric male patients undergoing penile surgeries. Methods The study was conducted on 40 randomly chosen patients in Ain Shams University Hospitals after approval of the medical ethical committee. Patients were divided randomly into two groups (20 each group) either receiving ultrasound-guided pudendal nerve block (PNB group) or caudal epidural block (CB group). In the PNB group, patients were injected with 0.3 mL/kg 0.25% bupivacaine and 1 ug/kg fentanyl. In the CB group, patients were injected with 1 mL/kg 0.25% bupivacaine and 1 ug/kg fentanyl. The two groups were adequately monitored and assessed pre, intra and post-operatively and they were compared regarding demographic data, pre, intra and postoperative hemodynamics, postoperative pain control using objective pain scale (OPS) score, consumption of paracetamol in the 1st 24 hours postoperatively and complications of both anesthetic techniques. Results This prospective randomized controlled single-blind clinical study was performed on total 40 patients of age 3 to 10 years scheduled for penile surgeries. For the primary outcome, there was a statistically significant increase in time to first analgesia in PNB group than CB group with p value &amp;lt; 0.001 while there was a statistically significant increase in total dose of paracetamol in CB group than PNB group with p value &amp;lt; 0.001. For OPS score, there was a statistically significant increase in pain score in CB group than PNB group at 6 h, 12 h and 24 h with p value = 0.02, 0.005 and 0.01, respectively. Conclusion From our study we can conclude that US guided PNB provided significantly prolonged postoperative analgesia and reduced the postoperative analgesic requirements as compared with caudal block in pediatric patients undergoing penile surgeries and also demonstrated that both analgesic techniques are safe.

Effect of pericapsular nerve group block and suprainguinal fascia iliaca block on postoperative analgesia and stress response in elderly patients undergoing hip arthroplasty: a prospective randomized controlled double-blind trial

BackgroundAs a novel regional analgesic technique, ultrasound-guided pericapsular nerve group (PENG) block has some potential advantages, and we designed a randomized clinical trial (RCT) to investigate whether the ultrasound-guided PENG block combined with general anesthesia can better reduce stress response, maintain intraoperative hemodynamic stability, and reduce postoperative analgesia in elderly hip arthroplasty compared with ultrasound-guided suprainguinal fascia iliaca block (SIFIB) combined with general anesthesia.MethodsSeventy-four subjects were enrolled over an 8-month period (20 April 2023 to 31 December 2023). All patients were divided into the test group (group P) and the control group (group S) using the envelope as the randomization method. The test group was treated with preoperative ultrasound-guided PENG block analgesia combined with general anesthesia and the control group was treated with preoperative ultrasound-guided SIFIB analgesia combined with general anesthesia. The primary outcome selected was the patient Visual Analogue Scale (VAS) score at 12 h postoperatively.ResultsAfter generalized estimating equations (GEE) analysis, there was a statistically significant difference in the main effect of postoperative VAS score in group P compared with group S (P = 0.009), the time effect of VAS score in each group was significantly different (P < 0.001), and there was no statistically significant difference in the group-time interaction effect (P = 0.069). There was no statistically significant difference in the main effect of intraoperative mean arterial pressure (MAP) change (P = 0.911), there were statistically significant differences in the time effect of MAP in each group (P < 0.001), and there were statistically significant differences in the interaction effect (P < 0.001).ConclusionsIn summary, we can conclude that in elderly patients undergoing hip fracture surgery, postoperative analgesia is more pronounced, intraoperative hemodynamic parameters are more stable, and intraoperative stress is less induced in patients receiving SIFIB than in patients receiving PENG block.

Effects of buccal acupuncture on postoperative analgesia in elderly patients undergoing laparoscopic radical gastrectomy: a randomized controlled trial.

This study aimed to evaluate the efficacy and safety of buccal acupuncture on postoperative analgesia, perioperative stress response and adverse events in elderly patients undergoing laparoscopic radical gastrectomy. It was a prospective, outcome assessor-blinded, randomized controlled trial, involving 90 patients aged 65-80 years who were treated with an elective laparoscopic radical gastrectomy. They were randomly assigned to buccal acupuncture group (Group B) and control group (Group C). Buccal acupuncture was applied to patients of Group B before the induction of general anesthesia, while no additional application was given to those in Group C. Patient-controlled intravenous analgesia (PCIA) with sufentanil was postoperatively performed in both groups. Sufentanil consumption and the Visual Analog Scale (VAS) score within 48 h postoperatively were assessed as primary outcomes. Secondary outcomes included peripheral levels of stress markers, intraoperative consumptions of anesthetic drugs and postoperative recovery. Patients in Group B presented significantly lower VAS scores within 24 h and less consumption of sufentanil within 48 h postoperatively (both p < 0.01). The awaking time, time to extubation and length of stay were significantly shorter in Group B than in Group C (p = 0.005, 0.001 and 0.028, respectively). Compared with Group C, stress response and inflammatory response within 24 h postoperatively were also significantly milder in Group B. The use of buccal acupuncture before general anesthesia induction favors the postoperative analgesic effect and recovery in elderly patients undergoing laparoscopic radical gastrectomy, the mechanism of which involves relieving postoperative stress response and inflammatory response. This study was registered in the Chinese Clinical Trial Registry (www.chictr.org.cn) on 15/06/2023 (ChiCTR2300072500).

Impact of thoracic paravertebral block and sufentanil on outcomes and postoperative cognitive dysfunction in thoracoscopic lung cancer surgery

BACKGROUND Postoperative pain management and cognitive function preservation are crucial for patients undergoing thoracoscopic surgery for lung cancer (LC). This is achieved using either a thoracic paravertebral block (TPVB) or sufentanil (SUF)-based multimodal analgesia. However, the efficacy and impact of their combined use on postoperative pain and postoperative cognitive dysfunction (POCD) remain unclear. AIM To explore the analgesic effect and the influence on POCD of TPVB combined with SUF-based multimodal analgesia in patients undergoing thoracoscopic radical resection for LC to help optimize postoperative pain management and improve patient outcomes. METHODS This retrospective analysis included 107 patients undergoing thoracoscopic radical resection for LC at The Affiliated Cancer Hospital of Zhengzhou University and Henan Cancer Hospital between May 2021 and January 2023. Patients receiving SUF-based multimodal analgesia (n = 50) and patients receiving TPVB + SUF-based multimodal analgesia (n = 57) were assigned to the control group and TPVB group, respectively. We compared the Ramsay Sedation Scale and visual analog scale (VAS) scores at rest and with cough between the two groups at 2, 12, and 24 h after surgery. Serum levels of epinephrine (E), angio-tensin II (Ang II), norepinephrine (NE), superoxide dismutase (SOD), vascular endothelial growth factor (VEGF), transforming growth factor-β1 (TGF-β1), tumor necrosis factor-α (TNF-α), and S-100 calcium-binding protein β (S-100β) were measured before and 24 h after surgery. The Mini-Mental State Examination (MMSE) was administered 1 day before surgery and at 3 and 5 days after surgery, and the occurrence of POCD was monitored for 5 days after surgery. Adverse reactions were also recorded. RESULTS There were no significant time point, between-group, and interaction effects in Ramsay sedation scores between the two groups (P &gt; 0.05). Significantly, there were notable time point effects, between-group differences, and interaction effects observed in VAS scores both at rest and with cough (P &lt; 0.05). The VAS scores at rest and with cough at 12 and 24 h after surgery were lower than those at 2 h after surgery and gradually decreased as postoperative time increased (P &lt; 0.05). The TPVB group had lower VAS scores than the control group at 2, 12, and 24 h after surgery (P &lt; 0.05). The MMSE scores at postoperative days 1 and 3 were markedly higher in the TPVB group than in the control group (P &lt; 0.05). The incidence of POCD was significantly lower in the TPVB group than in the control group within 5 days after surgery (P &lt; 0.05). Both groups had elevated serum E, Ang II, and NE and decreased serum SOD levels at 24 h after surgery compared with the preoperative levels, with better indices in the TPVB group (P &lt; 0.05). Marked elevations in serum levels of VEGF, TGF-β1, TNF-α, and S-100β were observed in both groups at 24 h after surgery, with lower levels in the TPVB group than in the control group (P &lt; 0.05). CONCLUSION TPVB combined with SUF-based multimodal analgesia further relieves pain in patients undergoing thoracoscopic radical surgery for LC, enhances analgesic effects, reduces postoperative stress response, and inhibits postoperative increases in serum VEGF, TGF-β1, TNF-α, and S-100β levels. This scheme also reduced POCD and had a high safety profile.

A randomised comparative study of erector spinae plane block versus low-dose ketamine-dexmedetomidine intravenous infusion as intraoperative opioid-free analgesia for modified radical mastectomy.

Opioid-sparing analgesia for acute postoperative pain after breast cancer surgery is crucial due to opioid-related side effects. The utilisation of erector spinae plane block and low-dose intravenous ketamine-dexmedetomidine are widely recognised as non-opioid analgesic methodologies. The objective of this study was to conduct a randomised trial to examine the analgesic efficacy of both approaches while minimising the use of opioids. Seventy-two female patients scheduled for unilateral modified radical mastectomy were recruited. They were allocated randomly to Group ESPB, which received ipsilateral ultrasound-guided erector spinae plane block by 20 mL bupivacaine 0.5% at the level of T5 after induction of general anaesthesia, and Group Ket-Dex, which received intravenous (IV) bolus 0.25 mg/kg of ketamine and 0.5 µg/kg of dexmedetomidine, followed by an IV infusion of 0.25 mg/kg of ketamine and 0.3 µg/kg of dexmedetomidine per hour. Total postoperative morphine consumption (24 h) was the primary outcome. The secondary outcomes were pain scores over 24 hours during rest, duration of analgesia, isoflurane consumption, time to awakening, postoperative nausea and vomiting (PONV), and postoperative serum cortisol level. The postoperative morphine consumption over 24-hour in Group ESPB was 3.26 mg (0-6.74) versus 2.35 mg (2.08-4.88) in Group Ket-Dex (P = 0.046). Group Ket-Dex had lower pain scores at rest, longer analgesia duration, longer awakening time, and lower postoperative serum cortisol levels. Intravenous low-dose ketamine-dexmedetomidine infusion intraoperatively with inhalational-based general anaesthesia provides superior opioid-sparing analgesia to that of ESPB in patients undergoing unilateral non-reconstructive modified radical mastectomy, with less postoperative opioid consumption and stress response.

Robotic-assisted surgery for left-sided colon and rectal resections is associated with reduction in the postoperative surgical stress response and improved short-term outcomes: a cohort study.

There is growing evidence that the use of robotic-assisted surgery (RAS) in colorectal cancer resections is associated with improved short-term outcomes when compared to laparoscopic surgery (LS) or open surgery (OS), possibly through a reduced systemic inflammatory response (SIR). Serum C-reactive protein (CRP) is a sensitive SIR biomarker and its utility in the early identification of post-operative complications has been validated in a variety of surgical procedures. There remains a paucity of studies characterising post-operative SIR in RAS. Retrospective study of a prospectively collected database of consecutive patients undergoing OS, LS and RAS for left-sided and rectal cancer in a single high-volume unit. Patient and disease characteristics, post-operative CRP levels, and clinical outcomes were reviewed, and their relationships explored within binary logistic regression and propensity scores matched models. A total of 1031 patients were included (483 OS, 376 LS, and 172 RAS). RAS and LS were associated with lower CRP levels across the first 4 post-operative days (p < 0.001) as well as reduced complications and length of stay compared to OS in unadjusted analyses. In binary logistic regression models, RAS was independently associated with lower CRP levels at Day 3 post-operatively (OR 0.35, 95% CI 0.21-0.59, p < 0.001) and a reduction in the rate of all complications (OR 0.39, 95% CI 0.26-0.56, p < 0.001) and major complications (OR 0.5, 95% CI 0.26-0.95, p = 0.036). Within a propensity scores matched model comparing LS versus RAS specifically, RAS was associated with lower post-operative CRP levels in the first two post-operative days, a lower proportion of patients with a CRP ≥ 150 mg/L at Day 3 (20.9% versus30.5%, p = 0.036) and a lower rate of all complications (34.7% versus 46.7%, p = 0.033). The present observational study shows that an RAS approach was associated with lower postoperative SIR, and a better postoperative complications profile.

Effects of the enhanced recovery after surgery (ERAS) protocol on the postoperative stress state and short-term complications in elderly patients with colorectal cancer.

The aim of this study was to evaluate the feasibility and necessity of enhanced recovery after surgery in elderly patients with colorectal cancer by observing inflammatory markers and postoperative complications. Hospitalized colorectal cancer patients from the Affiliated Hospital of Jiangsu University from January 2021 to September 2022 were included in the study and divided into two groups: Enhanced Recovery After Surgery (ERAS) and non-ERAS. Data on postoperative inflammatory markers and complications were also collected. A total of 313 patients with colorectal cancer were included: 182 in the ERAS group and 131 in the non-ERAS group. The patients in the ERAS group had significantly shorter days of postoperative hospitalization, urinary catheter and drainage tube withdrawal times, and recovery of bowel function (P < .05) than those of the non-ERAS group. Moreover, the ERAS group had lower hospitalization expenses than those of the non-ERAS group (P < .05). However, the procalcitonin and tumor necrosis factor (TNF)-α levels in the ERAS group was significantly lower than those in the non-ERAS group on postoperative days 1 and 3 (P < .05), and the interleukin (IL)-6 and IL-10 levels in the ERAS group were significantly lower than those in the non-ERAS group on the 1st, 3rd, and 5th postoperative days (P < .05). The C-reactive protein (CRP) and white blood cell (WBC) levels in the ERAS group were lower than those in the non-ERAS group on postoperative days 3 and 5 (P < .05). However, the hemoglobin levels did not differ significantly (P > .05). The albumin levels did not differ significantly between the two groups before surgery (P > .05); however, the albumin level in the ERAS group was higher than that in the non-ERAS group on postoperative days 3 and 5 (P < .05). The ERAS patients had lower albumin levels after surgery than those of the non-ERAS patients (P < .05). ERAS leads to a series of perioperative optimization measures, thereby reducing the postoperative stress response in elderly patients with colorectal cancer and the occurrence of perioperative complications.

Clinical nursing value of predictive nursing in reducing complications of pregnant women undergoing short-term massive blood transfusion during cesarean section.

Cesarean hemorrhage is one of the serious complications, and short-term massive blood transfusion can easily cause postoperative infection and physical stress response. However, predictive nursing intervention has important clinical significance for it. To explore the effect of predictive nursing intervention on the stress response and complications of women undergoing short-term mass blood transfusion during cesarean section (CS). A clinical medical record of 100 pregnant women undergoing rapid mass blood transfusion during sections from June 2019 to June 2021. According to the different nursing methods, patients divided into control group (n = 50) and observation group (n = 50). Among them, the control group implemented routine nursing, and the observation group implemented predictive nursing intervention based on the control group. Moreover, compared the differences in stress response, complications, and pain scores before and after the nursing of pregnant women undergoing rapid mass blood transfusion during CS. The anxiety and depression scores of pregnant women in the two groups were significantly improved after nursing, and the psychological stress response of the observation group was significantly lower than that of the control group (P < 0.05). The heart rate and mean arterial pressure (MAP) of the observation group during delivery were lower than those of the control group, and the MAP at the end of delivery was lower than that of the control group (P < 0.05). Moreover, different pain scores improved significantly in both groups, with the observation group considerably less than the control group (P < 0.05). After nursing, complications such as skin rash, urinary retention, chills, diarrhea, and anaphylactic shock in the observation group were 18%, which significantly higher than in the control group (4%) (P < 0.05). Predictive nursing intervention can effectively relieve the pain, reduce the incidence of complications, improve mood and stress response, and serve as a reference value for the nursing of women undergoing rapid mass transfusion during CS.

Inflammatory stress response after transanal vs laparoscopic total mesorectal excision: a cohort study based on the TaLaR trial.

Transanal total mesorectal excision (taTME) is a novel approach to radical surgery for low rectal cancer; however, it is not clear whether taTME causes a more severe inflammatory stress response than laparoscopic total mesorectal excision (laTME). Therefore, the authors conducted this study to address this question, with the secondary objective of analyzing the predictive effect of inflammatory indexes on postoperative infective complications between laTME and taTME. A total of 545 cases of laTME and 544 cases of taTME from the TaLaR randomized controlled trial were included. Inflammatory stress response was assessed via C-reactive protein (CRP), white blood cell count, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, lymphocyte-monocyte ratio, and prognostic nutritional index. Inflammatory indexes were measured and calculated preoperatively (t1) and on postoperative days one (t2) and seven (t3). The accuracy of inflammatory indexes as predictor of infective complications was evaluated by areas under the receiver operating characteristic curve. Preoperative blood parameters were comparable between the two surgical methods. There were no significant differences in CRP, white blood cell count, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, lymphocyte-monocyte ratio, or prognostic nutritional index between the two surgical methods at any time point ( P >0.05). Among the inflammatory indexes at three time points, CRP on the first postoperative day was the most accurate predictor of infective complications, which is suitable for two surgical methods. The AUC was 0.7671 ( P <0.0001) with a cutoff of 39.84mg/l, yielding 94% sensitivity and 47% specificity. Compared with laTME, taTME surgery has no obvious disadvantage with respect to the postoperative inflammatory stress response. In addition, inflammatory indexes were favorable in predicting infective complications, with the best results for CRP on the first postoperative day. Defining the specific predictors for laTME and taTME is unnecessary.

A Menu-based Nursing Intervention Using the Health Action Process Approach Model on the Stress Response and Postoperative Rehabilitation after Liver Cancer Surgery

We investigated the effects of a menu-based nursing intervention using the health actionprocess approach (HAPA) model on patient stress response and postoperative rehabilitation after livercancer surgery. Methods: We randomly assigned 120 patients with liver cancer to intervention (N=60)or control groups (N=60). Intervention patients received a menu-based nursing intervention using theHAPA model; control patients received routine care. We measured physiological and psychological stressresponses using C-reactive protein (CRP) and cortisol (Cor) levels and the Hamilton anxiety rating scale(HAMA) and the Hamilton depression rating scale (HAMD). Results: Intervention group HAMA and theHAMD scores were lower than the control group’s (p &lt; .05). Postoperative intervention group CRP andCor levels were lower than control group levels at 1 and 3 days (p &lt; .05). Those in the intervention grouphad a shorter time until their first exhaust and meal and a shorter hospital stay than those in the controlgroup (p &lt; .05). Self-management ability and quality of life scores of the intervention group were higherthan for the control group (p &lt; .05). Conclusion: The menu-based nursing intervention using the HAPAmodel can reduce postoperative stress response and complications and accelerate postoperative recovery.

Association Preoperative Protein Adequacy and Post Elective Laparotomy Surgical Site Infection.

Postoperative complications tend to occur in high-risk populations, including those undergoing major surgery. Surgical site infections (SSI) are some of the most common postoperative complications in laparotomy procedures. Surgery induces a postoperative stress response, triggering an inflammatory process that increases muscle protein proteolysis. Preoperative protein intake increases muscle protein reserves and supports postoperative wound healing and immunity. This study analyzed the association between preoperative protein adequacy and post-elective laparotomy SSI. A prospective cohort study was conducted on 93 subjects with an adequate protein group of 48 subjects and an inadequate protein group of 45 subjects undergoing elective laparotomy at Dr. Cipto Mangunkusumo Hospital, Jakarta. The protein adequacy was analyzed using an interview method for seven days preoperatively. Patient monitoring was carried out for 30 days postoperatively to assess the complications in the form of SSIs. The association between protein adequacy and SSI was analyzed using a Chi-Square test, and multivariate analysis was performed to assess the factors most associated with post-elective laparotomy SSI. An association was observed between preoperative protein adequacy and post-elective laparotomy SSI (RR 3.413; 95% CI, 1.363-8.549; p=0.004). Multivariate analysis showed that the preoperative protein adequacy and preoperative albumin levels were strongly predictive of the occurrence of SSI. The preoperative protein adequacy and albumin levels were strongly related to predicting the post-elective laparotomy SSI.

Comparison of the effects of sufentanil-dominant anaesthesia/analgesia and epidural anaesthesia/analgesia on postoperative immunological alterations, stress responses and prognosis in open hepatectomy: a randomized trial.

Both in vitro and in animal studies have shown immunosuppressive effects of opioids which might provoke tumour growth and metastasis, while no definite results were shown in previous clinical studies. To find out the effects between general anaesthesia combined with sufentanil target-controlled infusion (SGA) and general anaesthesia combined with epidural anaesthesia (EGA) on immunological alterations, stress responses and prognosis in patients undergoing open hepatectomy, a prospective, non-inferiority, randomized-controlled study was performed. Patients with liver neoplasms undergoing open hepatectomy were randomly assigned to either SGA (n=81) or EGA (n=81) group. The primary outcome was the ratio of interferon (IFN)-γ/interleukin (IL)-4 at 24 h after surgery (T3). The secondary outcomes included immune-related cytokines, circulating immune cells, stress-related cytokines, cortisol and blood glucose, visual analogue scale scores. Plasma was sampled at five-time points [baseline/before surgery (T0), 5 min after portal block release (T1), 1 h after surgery (T2), T3, and on a postoperative day (POD)5 (T4)]. Cancer-related outcomes, including recurrence, metastasis and survival, were followed up at 3 months and 1 year after surgery. The IFN-γ/IL-4 ratios were comparable between both groups at T3 {median [interquartile range (IQR)]: 20.78 (12.73-29.18) vs. 19.52 (13.98-29.29), P=0.607}. At T3, the proportions of circulating T cells were decreased, while those of B and natural killer cells were increased. The plasma level of tumour necrosis factor (TNF)-α at T2 was significantly higher in the SGA group [median (IQR): 7.45 (6.20-9.80) vs. 5.95 (4.95-7.45) pg/mL, P<0.001]. Patient-controlled intravenous analgesia was less effective than epidural analgesia on POD0 and POD2. For hepatocellular carcinoma (HCC)-related outcomes, no significant differences were found in either short- or long-term follow-ups. Although the levels of TNF-α were higher in the SGA group, the tumour-related immunological alterations and follow-ups showed no difference between groups. SGA appears not to be inferior to EGA regarding tumour-related immunity and prognosis. Intravenous opioid use appears not to be inferior to epidural anaesthesia, and can be used safely in HCC patients without worsening patients' prognosis.

Effect of da Vinci robot versus thoracoscopic surgery on lung function and oxidative stress levels in NSCLC patients: a propensity score-matched study.

To evaluate the short-term efficacy, lung function, and oxidative stress levels between the robotic-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery group (VATS) for non-small cell lung cancer (NSCLC). We conducted a retrospective cohort study, selecting 248 NSCLC patients who underwent minimally invasive lobectomy at the Department of Thoracic Surgery, Gansu Provincial People's Hospital, from August 2019 to February 2023. There were 105 patients in the RATS group and 143 patients in the VATS group. The patients in the two groups were subjected to 1:1 propensity score matching analysis (PSM), and the perioperative indicators were recorded. The levels of oxidative stress factors (superoxide dismutase, SOD; malondialdehyde, MDA) and inflammatory factors were measured 1day before surgery and 3days after surgery, respectively. Pulmonary function and patient quality of life were measured at 1day preoperatively and 3months postoperatively. There are 93 patients in each group after PSM. Compared to the VATS group, the RATS group had shorter operation time, less intraoperative blood loss, greater number and groups of lymph nodes cleared, and shorter postoperative hospital stay. The SOD level in the RATS group was higher and the MDA level was lower than that in the VATS group after surgery. Postoperative inflammatory cytokine levels were less elevated in the RATS group than in the VATS group. At 3months postoperatively, FVC%, FEV1%, and GQOLI-74 scores were higher in the RATS group than in the VATS group. Compared to VATS lobectomy, RATS lobectomy has the advantages of shorter operative time, lesser bleeding, more lymph node dissection, faster postoperative recovery, and lesser impact on postoperative lung function. It is also capable of reducing the postoperative oxidative stress and inflammatory response, which can improve patients' quality of life.

Effects of Locking Compression Plate and Intramedullary Nailing on the Healing, Stress Factors and Inflammatory Factors of Patients with Open Humerus Fractures in Emergency

To investigate the efficacy of internal fixation with locking compression plate and intramedullary nailing in the treatment of open humerus fractures in emergency and their influences on the stress factors and inflammatory factors of patients. Sixty patients with open humerus fractures admitted in emergency department from December 2017 to December 2019 were enrolled in this study, and they were randomly divided into group A (n = 30) and group B (n = 30) based on treatment methods. Patients in group A received the internal fixation with locking compression plate, while patients in group B were treated with intramedullary nailing. The study compared various factors between the two groups, including operation time, surgical incision size, intraoperative blood loss, postoperative weight-bearing time, healing time, treatment effectiveness, inflammatory factors, stress factors, and the incidence of postoperative complications. In group B, patients had significantly shorter operation times and less intraoperative blood loss compared to group A (P &lt; 0.05). Additionally, patients in group B started postoperative shoulder training earlier. The surgical incision size and fracture healing time did not show significant differences between the two groups (P &gt; 0.05). The excellent and good rate of treatment in group A was 93.33% while 96.67% for group B (P &gt; 0.05). On the 7th day after operation, patients in both groups exhibited increased serum levels of ESR, WBC, and IL-6. However, group B demonstrated significantly lower levels of these factors compared to group A (P &lt; 0.05). Moreover, the norepinephrine (NE), epinephrine (E) and cortisol (Cor) all increased, and group B demonstrated lower levels than group A (P &lt; 0.05). The incidence of postoperative complications in groups A and B were 36.67% and 13.33%, respectively (P &lt; 0.05). Both internal fixation with a locking compression plate and intramedullary nailing are effective in treating open humerus fractures in emergency cases. However, intramedullary nailing offers advantages such as shorter operation time, reduced intraoperative blood loss, lower postoperative stress and inflammatory responses, and a lower incidence of postoperative complications. Therefore, intramedullary nailing should be promoted as a treatment option for these fractures.

Effect of perioperative application of dexmedetomidine on post-operative stress reaction, pain and prognostic adverse effects in patients undergoing gynaecological laparoscopy.

The aim of this study was to analyse the effect of perioperative dexmedetomidine (DEX) application on stress response, post-operative pain and prognosis in patients undergoing gynaecologic laparoscopy. One hundred and sixty-eight patients admitted for gynaecologic laparoscopic surgery from May 2020 to November 2022 were included in the study. The patients were randomly divided into pre-operative DEX group (n = 56), intraoperative DEX group (n = 56) and post-operative DEX group (n = 56) according to the application of DEX in the perioperative period. The visual analogue scale (VAS), time awake, extubation time, pneumoperitoneum time, post-anaesthesia care unit (PACU) stay time and Richmond agitation-sedation scale score (RASS) were recorded. Patients in both the pre-operative and intraoperative DEX groups had substantially shorter wakeup and extubation times than those in the post-operative DEX group. Patients in the pre-operative DEX group had considerably shorter wakeup and extubation times than those in the intraoperative DEX group, and their pneumoperitoneum time was significantly shorter than that of the post-operative DEX group (P < 0.001). The RASS scores of the pre-operative DEX group and intraoperative DEX group were significantly lower than those of the post-operative DEX group at 1 h, 6 h and 12 h after surgery. Meanwhile, at all time periods, the RASS scores of patients in the pre-operative DEX group were considerably lower than those in the intraoperative DEX group (P < 0.01). The VAS scores of patients in the pre-operative DEX group and intraoperative DEX group were evidently lower than those in the post-operative DEX group at 0.5 h, 2 h and 12 h postoperatively, and the VAS scores of patients in the pre-operative DEX group were markedly lower than those in the intraoperative DEX group (P < 0.001). The incidence of nausea and vomiting was significantly lower in the pre-operative DEX group than in the intraoperative DEX group and the post-operative DEX group at 0-2 h, >2-12 h and >12-24 h postoperatively (P < 0.001). The incidence of nausea and vomiting in the intraoperative DEX group was significantly lower than that in the post-operative DEX group from 0 to 2 h after surgery (P < 0.05). The incidence of adverse reactions was not significantly different amongst the three groups of patients (P > 0.05). Pre-operative and intraoperative application of DEX can help reduce post-operative pain and stress responses, help patients recover quickly after surgery and improve patient prognosis, especially the pre-operative application of DEX.
