Comparison of the effects of general anesthesia between remimazolam and propofol in pediatric patients undergoing binocular strabismus day surgery

Objective: To compare the effects of general anesthesia between remimazolam and propofol in pediatric patients undergoing binocular strabismus day surgery. Methods: Prospectively, 60 pediatric patients, American Society of Anesthesiologists (ASA) grade Ⅰ-Ⅱ, scheduled to undergo binocular strabismus daytime surgery in Beijing Tongren Hospital under general anesthesia with laryngeal mask airway from December 2021 to May 2022 were selected. They were randomly divided into Remimazolam group and Propofol group with 30 cases in each group, according to the ratio of 1∶1 by SPSS program. Patients in Remimazolam group were induced by remimazolam, remifentanil and micuronium chloride, and maintained by remimazolam and remifentanil. Patients in Propofol group were induced by propofol, remifentanil and micuronium chloride, and maintained by propofol and remifentanil. Patients in Remimazolam group were given 0.1 mg of flumazenil for antagonism 3 minutes after operation, while children in Propofol group waited for natural awakening. The primary outcome was the time from drug withdrawal to laryngeal mask removal after operation. The secondary outcomes included the time for consciousness loss during induction, intraoperative hemodynamic data [mean arterial pressure (MAP) and heart rate], the success rate of sedation, the awareness rate during operation, and the incidence of adverse events after admission to postanesthesia care unit(PACU). Results: The Remimazolam group included 12 males and 18 females, aged (5.0±1.4) years. There were 14 males and 16 females in the Propofol group, aged (5.3±1.3) years. The time from drug withdrawal to laryngeal mask removal in Remimazolam group was (6.5±1.2) min, which was shorter than that in Propofol group of (10.7±1.9) min (P<0.001). The time for consciousness loss during induction was (38.1±4.8) s in Remimazolam group, which was longer than that in Propofol group of (31.6±4.9) s (P<0.001). The variability of MAP and heart rate of patients during operation in Remimazolam group was lower than that in Propofol group (all P<0.05). There was no significant difference in sedation success rate, intraoperative awareness and adverse reactions in PACU between the two groups (all P>0.05). Conclusion: In pediatric patients with binocular strabismus during daytime surgery, general anesthesia with remimazolam can shorten the time from drug withdrawal to laryngeal mask removal after operation without increasing the incidence of postoperative adverse reactions and can provide more stable hemodynamics.

Application of multimodal standardized analgesia under the concept of enhanced recovery after surgery in laparoscopic radical colorectal cancer surgery.

To observe the efficacy and safety of multimodal standardized analgesia in patients undergoing laparoscopic radical colorectal cancer surgery. A prospective, double-blind, randomized study of patients who were admitted to our hospital between December 2020 and March 2022 with a diagnosis of colorectal cancer and who intended to undergo elective laparoscopic radical colorectal cancer surgery was conducted. The participants were randomly divided into two intervention groups, namely, a multimodal standardized analgesia group and a routine analgesia group. In both groups, the visual analogue scale (VAS) pain scores while resting at 6h, 24h, 48h and 72h and during movement at 24h, 48h and 72h; the number of patient controlled intravenous analgesia (PCIA) pump button presses and postoperative recovery indicators within 3 days after surgery; the interleukin-6 (IL-6) and C-reactive protein (CRP) levels on the 1st and 4th days after surgery; and the incidence of postoperative adverse reactions and complications were recorded. Compared with the control group, the multimodal standardized analgesia group had significantly lower VAS pain scores at different time points while resting and during movement (P<0.05), significantly fewer PCIA pump button presses during the first 3 postoperative days (P<0.05), and significantly lower IL-6 and CRP levels on the 1st postoperative day (P<0.05). There was no statistically significant difference in the time to out-of-bed activity, the time to first flatus, the IL-6 and CRP levels on the 4th postoperative day or the incidence of postoperative adverse reactions and complications between the two groups (P >0.05). For patients undergoing laparoscopic radical colorectal cancer surgery, multimodal standardized analgesia with ropivacaine combined with parecoxib sodium and a PCIA pump had a better analgesic effect, as it effectively inhibited early postoperative inflammatory reactions and promoted postoperative recovery and did not increase the incidence of adverse reactions and complications. Therefore, it is worthy of widespread clinical practice.

The impact of nursing interventions on the rehabilitation outcome of patients after lumbar spine surgery

BackgroundThis study aimed to investigate the impact of nursing interventions on the rehabilitation outcomes of patients after lumbar spine surgery and to provide effective references for future postoperative care for patients undergoing lumbar spine surgery.MethodsThe study included two groups: a control group receiving routine care and an observation group receiving additional comprehensive nursing care. The comprehensive care encompassed postoperative rehabilitation, pain, psychological, dietary management, and discharge planning. The Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), Short-Form 36 (SF-36) Health Survey, self-rating depression scale (SDS) and self-rating anxiety scale(SAS) were used to assess physiological and psychological recovery. Blood albumin, haemoglobin, neutrophil counts, white blood cell counts, red blood cell counts, inflammatory markers (IL-6, IL-10, and IFN-γ) were measured, and the incidence of postoperative adverse reactions was also recorded.ResultsPatients in the observation group exhibited significantly improved VAS, ODI, SF-36, SDS and SAS scores assessments post-intervention compared to the control group (P < 0.05). Moreover, levels of IL-6, IL-10, and IFN-γ were more favorable in the observation group post-intervention (P < 0.05), indicating a reduction in inflammatory response. There was no significant difference in the incidence of postoperative adverse reactions between the groups (P > 0.05), suggesting that the comprehensive nursing interventions did not increase the risk of adverse effects.ConclusionComprehensive nursing interventions have a significant impact on the postoperative recovery outcomes of patients with LSS, alleviating pain, reducing inflammation levels, and improving the overall quality of patient recovery without increasing the patient burden. Therefore, in clinical practice, it is important to focus on comprehensive nursing interventions for patients with LSS to improve their recovery outcomes and quality of life.

Effects of a Modified Long-Acting Cocktail on Analgesia and Enhanced Recovery After Total Hip Arthroplasty: A Double-Blinded Randomized Clinical Trial

BackgroundWe compared the efficacy and safety of a modified cocktail for postoperative analgesia and early functional rehabilitation in patients undergoing total hip arthroplasty (THA). MethodsMagnesium sulfate and sodium bicarbonate were added to a cocktail of ropivacaine, epinephrine, and dexamethasone. Primary outcome measures were visual analog scale (VAS) pain scores at various intervals after surgery, morphine consumption for rescue analgesia after surgery, and time to first rescue analgesia. Secondary outcomes were hip function after surgery, daily walking distance, quadriceps muscle strength, and the incidence of postoperative adverse reactions. ResultsMorphine consumption was significantly lower in the modified cocktail group than in the control group in the first 24 hours after surgery (6.2 ± 6.0 versus 14.2 ± 6.4 mg, P < .001), as was total morphine consumption (10.0 ± 8.6 versus 19.2 ± 10.1 mg, P < .001). The duration of the first rescue analgesia was significantly prolonged (23.7 ± 10.3 versus 11.9 ± 5.8 mg, P < .001). Morphine consumption was also reduced in the magnesium sulfate and sodium bicarbonate groups over a 24-hour period compared to the control group (P < .001). The modified cocktail group had significantly lower resting VAS pain scores than the control group within 24 hours after surgery (P < .050). The VAS pain scores during movement within 12 hours after surgery were also lower (P < .050). The experimental groups showed better hip range of motion (P < .050) and longer walking distance (P < .050) on the first postoperative day, and levels of inflammatory markers were significantly reduced. The incidence of postoperative adverse reactions was similar among the 4 groups. ConclusionsThe modified cocktail with a new adjuvant can prolong the duration of postoperative analgesia, reduce the dosage of rescue analgesics, and accelerate early postoperative functional recovery in patients undergoing THA.

Comparison of Thoracoscopy-Guided Thoracic Paravertebral Block and Ultrasound-Guided Thoracic Paravertebral Block in Postoperative Analgesia of Thoracoscopic Lung Cancer Radical Surgery: A Randomized Controlled Trial.

Ultrasound-guided thoracic paravertebral block (UTPB) is widely used for postoperative analgesia in thoracic surgery. However, it has many disadvantages. Thoracoscopy-guided thoracic paravertebral block (TTPB) is a new technique for thoracic paravertebral block (TPB). In this study, we compared the use of TTPB and UTPB for pain management after thoracoscopic radical surgery for lung cancer. In total, 80 patients were randomly divided 1:1 into the UTPB group and the TTPB group. The surgical time of TPB, the success rate of the first puncture, block segment range, visual analog scale (VAS) scores at 2, 6, 12, 24, and 48h post operation, and the incidence of postoperative adverse reactions were compared between the two groups. The surgical time of TPB was significantly shorter in the TTPB group than in the UTPB group (2.2 ± 0.3 vs. 5.7 ± 1.7min, t = - 12.411, P < 0.001). The success rate of the first puncture and the sensory block segment were significantly higher in the TTPB group than in the UTPB group (100% vs. 76.9%, χ2 = 8.309, P < 0.001; 6.5 ± 1.2 vs. 5.1 ± 1.3 levels, t = - 5.306, P < 0.001, respectively). The VAS scores were significantly higher during rest and coughing at 48h post operation than at 2, 6, 12, and 24h post operation in the TTPB group. The VAS scores were significantly lower during rest and coughing at 12 and 24h post operation in the TTPB group than in the UTPB group (rest: 2.5 ± 0.4 vs. 3.4 ± 0.6, t = 7.325, P < 0.001; 2.5 ± 0.5 vs. 3.5 ± 0.6, t = 7.885, P < 0.001; coughing: 3.4 ± 0.6 vs. 4.2 ± 0.7, t = 5.057, P < 0.001; 3.4 ± 0.6 vs. 4.2 ± 0.8, t = 4.625, P < 0.001, respectively). No significant difference was observed in terms of postoperative adverse reactions between the two groups. Compared with UTPB, TTPB shows advantages, such as simpler and more convenient surgery, shorter surgical time, a higher success rate of the first puncture, wider block segments, and superior analgesic effect. TTPB can effectively reduce postoperative pain due to thoracoscopic lung cancer radical surgery. https://www.chictr.org.cn , identifier ChiCTR2300072005, prospectively registered on 31/05/2023.

Analgesic effect of the ultrasound-guided thoracolumbar paravertebral block in patients undergoing robot-assisted laparoscopic nephrectomy: a randomized controlled trial.

Paravertebral block has similar effect as epidural anesthesia, and has good somatic and visceral analgesic effect. Paravertebral block is widely used in thoracic surgery, but rarely used in abdominal surgery. This study aimed to evaluate the analgesic effect of thoracolumbar paravertebral block in patients undergoing robot-assisted laparoscopic nephrectomy. One hundred patients undergoing elective robot-assisted laparoscopic nephrectomy were included in this study. Based on whether the thoracolumbar paravertebral block was performed, the patients were randomly divided into the thoracolumbar paravertebral block combined with general anesthesia group (TL-PVB group) and simple general anesthesia group (NO-PVB group). Oxycodone was administered for patient-controlled intravenous analgesia (PCIA). The primary outcomes included the amount of remifentanil used during surgery, the amount of oxycodone used in 24 and 48h after surgery. Secondary outcomes included the changes of heart rate (HR) and mean arterial pressure (MAP), time for the first analgesia administration, visual analog score (VAS) of pain during rest and movement, and time of postoperative recovery. Compared to the NO-PVB group, the amount of remifentanil used during surgery in patients with TL-PVB group was significantly reduced (1.78 ± 0.37mg vs. 3.09 ± 0.48 mg, p < 0.001), the amount of oxycodone used 24h after surgery was significantly reduced (8.70 ± 1.70mg vs. 13.79 ± 2.74 mg, p < 0.001), and the amount of oxycodone used 48h after surgery was remarkably reduced (21.83 ± 4.28mg vs. 27.27 ± 4.76 mg, p < 0.001). There were significant differences in the changes of HR and MAP between the two groups (p < 0.001). The first analgesic requirement time of TL-PVB group was significantly longer than that of NO-PVB group (468.56 ± 169.60min vs. 113.48 ± 37.26min, p < 0.001). The postoperative VAS during rest and movement of TL-PVB group were significantly lower than that of NO-PVB group (p < 0.01). Compared with NO-PVB group, patients in TL-PVB group needed shorter time to awaken from anesthesia, leave the operating room, anal exhaust, get out of bed, and had shorter length of postoperative hospital stay (p < 0.001). The incidence of postoperative adverse reactions were lower in the TL-PVB group than that in the NO-PVB group (p < 0.05). Ultrasound-guided thoracolumbar paravertebral block significantly reduces intraoperative and postoperative opioid consumption, and provides better analgesia in patients undergoing robot-assisted laparoscopic nephrectomy, which is a recommendable combined anesthesia technique.

Effect of Preventive Care on Postoperative Rehabilitation and Nutritional Status in Patients with Cerebral Hemorrhage

Cerebral hemorrhage is a common cerebrovascular disease affecting middle-aged and older adults, with an increasing annual incidence. Surgical removal of intracranial hematomas can save the lives of patients with cerebral hemorrhage. However, surgery-induced stress injuries can severely affect the perioperative nutritional status of patients, leading to an adverse prognosis. This study aimed to examine the effect of preventive care on patients with cerebral hemorrhage to improve patient safety during treatment. We found that patients in the experimental group who received preventive care had substantially improved postoperative rehabilitation quality, a decreased incidence of postoperative adverse reactions, and a shortened hospital stay than those in the control group who received routine care. Furthermore, preventive care reduced the risk of malnutrition and considerably improved the nutritional status of patients with CH. Preventive care can effectively improve the postoperative safety of patients with CH, shorten their rehabilitation cycle, promote their body function recovery, and enhance their nutritional status, which is essential in clinical practice.

Stress response and safety of lidocaine combined with dexmedetomidine in patients undergoing laparoscopic hysterectomy

Purpose: To investigate the anesthetic effect and safety issues when lidocaine is combined with dexmedetomidine in laparoscopic hysterectomy.&#x0D; Methods: The data for 100 patients from the Anesthesiology Department of Changzhou Second People's Hospital Affiliated to Nanjing Medical University who underwent laparoscopic total hysterectomy were randomly but equally divided into a control group and a combination group. Lidocaine hydrochloride was administered by infusion in the control group, while dexmedetomidine and lidocaine were administered together in the combination group. Inflammatory factors and stress hormone levels before and after the operation, as well as the incidence of adverse reactions following the operation, hemodynamic index, visual pain simulation (VAS) score, and sedation score at various times after the operation were evaluated in the two groups. Furthermore, the incidence of postoperative adverse reactions were also recorded and compared between the two groups.&#x0D; Results: The combination group's recovery time was significantly longer than that of the control group (p &lt; 0.05). At the point of extubation and 10 min after, mean arterial pressure (MAP) and heart rate (HR) in the combination group were significantly lower than those of the control group, respectively (p &lt; 0.05), while the combination group's VAS and Ramsay scores were statistically lower than those of the control group at 30 min, 24 h, and 48 h following surgery, respectively (p &lt; 0.05). The incidence of nausea and vomiting in the combination group was significantly lower than that in the control group (28.0% vs 58.0%, p &lt; 0.05).&#x0D; Conclusion: Lidocaine and dexmedetomidine, when combined, enhance hemodynamics, postoperative analgesia, and sedation in laparoscopic hysterectomy patients. The combination also lowers inflammatory stress and stress hormone levels, as well as the risk of nausea and vomiting, leading to better safety in the patients. However, multicenter trials are recommended to validate these findings prior to its use clinical practice.

Comparison of Callisphere Drug-Eluting Beads Transarterial Chemoembolization and Conventional Transarterial Chemoembolization for the treatment of Hepatocellular Carcinoma.

To compare the efficacy of CalliSphere drug-eluting beads (DEBs) and conventional (c) transarterial chemoembolization (TACE) in the treatment of hepatocellular carcinoma (HCC). We retrospectively reviewed the clinical data of 125 patients with HCC who had received treatment in Affiliated Hospital of North Sichuan Medical College from January 2018 to February 2019. Sixty-one patients underwent DEB-TACE (observation group) and 64 patients underwent cTACE (control group). The clinical efficacies, overall survivals, and incidence of postoperative adverse reactions between the two groups were compared. The objective response rate in the observation group (85.25%) was higher than that in the control group (70.31%; P<0.05). The disease control in the observation group (96.72%) was higher than that in the control group (85.94%; P<0.05). The median survival time of the observation group (24.85 months) was significantly higher than that in the control group (18.18 months; P<0.05). The incidence of adverse reactions in the observation group (4.92%) was lower than that in the control group (17.19%, P<0.05). In the treatment of HCC, Callisphere DEB-TACE has better efficacy and longer patient survival with fewer adverse reactions compared to cTACE.

Combination of Remimazolam, Remifentanil Anesthesia, and Enteral Nutrition Support Restores Vital Signs and Nutritional Status of Patients Undergoing Intravascular Interventional Therapy for Intracranial Aneurysms

Ninety-eight patients from our hospital were included in the study from March 2022 to March 2023. The patients were divided into two groups: 49 patients received propofol + remifentanil in the control group and 49 patients received remimazolam + remifentanil in the observation group. Postoperatively, the control group accepted parenteral nutrition support, while the observation group accepted enteral nutrition support. The observation group experienced a longer duration of consciousness loss but shorter times for consciousness recovery and trachea extubation than the control group. Although both groups experienced elevated mean blood pressure, heart rate, norepinephrine, angiotensin II, and plasma cortisol levels during tracheal intubation and extraction, the observation group showed differences compared to the control group. No statistical significance was discovered in the incidence of postoperative adverse reactions between the two groups (P = 0.29). Furthermore, tumor necrosis factor-α and interleukin-6 levels were lower in the observation group than in the control group, while total protein, albumin, and hemoglobin levels were higher. Overall, remimazolam combined with remifentanil demonstrated superiority over propofol combined with remifentanil in the perioperative period for patients undergoing intravascular interventional therapy for intracranial aneurysms.

Treatment of Cystic-Solid Thyroid Nodules with Ultrasound-Guided Radiofrequency Ablation and Enhancement of Thyroid Function.

To investigate the efficacy of ultrasound-guided radiofrequency ablation and its effect on thyroid function in patients with cystic-solid thyroid nodules. We enrolled 90 patients with cystic-solid thyroid nodules and randomly assigned to either a control group (n = 37) or an observation group (n = 53). Patients in the observation group underwent ultrasound-guided radiofrequency ablation, while those in the control group were treated with ultrasound-guided lauromacrogol. Thyroid function was monitored, and complications were recorded for both groups, while nodule reduction rates were compared across a range of volumes and time periods. One month after surgery, the observation group had a larger volume of nodules than the control group, while at 12 months, the volume of nodules in the observation group was smaller. (P < 0.05). Thyroid-stimulating hormone (TSH), free thyroxine 4 (FT4), and free triiodothyronine (FT3) levels were all within normal ranges after treatment in both groups and showed no significant differences from pre-treatment levels. (P > 0.05). There was no statistically significant difference between the total incidence of adverse reactions in the control group (8.11%) and the observation group (5.66%) (P > 0.05). With a low incidence of postoperative adverse reactions, the ultrasound-guided radiofrequency ablation protocol in the clinical treatment of patients with cystic-solid thyroid nodules can effectively reduce the volume of solid thyroid nodules without affecting the thyroid function of patients and can achieve more ideal treatment effectiveness, and is deserving of promotion.

Effect of postoperative application of esketamine on postoperative depression and postoperative analgesia in patients undergoing pancreatoduodenectomy: a randomized controlled trial protocol

BackgroundPancreatoduodenectomy (PD) is traumatic, difficult to perform, and has a high incidence of postoperative complications and perioperative mortality. Postoperative complications and pain occur frequently and seriously affect the psychological status of patients. Esketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has analgesic and antidepressant effects. In this study, we aim to investigate the effect of esketamine on postoperative depression and pain in patients undergoing PD.Methods/designThis prospective, single-center, randomized control trial will include 80 patients who will undergo elective PD. The patients will be randomly assigned to two groups: the experimental group that will receive esketamine (n = 40) and the control group (n = 40). In the esketamine group, the analgesic pump will be connected immediately after surgery. A solution of esketamine 1.5 mg/kg + sufentanil 2 µg/kg, diluted to 150 mL, will be administered continuously for 72 h at the background infusion and impact doses of 1 mL/h and 2 mL/time, respectively; the locking time will be 10 min. The control group will receive sufentanil 2 µg/kg that will be administered as per the esketamine group. The primary outcome will be the Hamilton Depression Scale (HAMD-17) score on the third day post-surgery (POD3). Secondary study indicators will include (1) visual analog scale (VAS) score and HAMD-17 score prior to surgery, immediately after entering the postanesthesia care unit (PACU) and 1, 2, 3, 4, and 5 days after surgery; (2) Richmond Agitation-Sedation Scale (RASS) score at 1, 2, 3, 4, and 5 days after surgery; (3) consumed doses of sufentanil and esketamine after surgery; (4) postoperative analgesia pump effective press times, rescue analgesia times, and rescue drug dosage, recording the number of rescue analgesia and rescue drug dosage at 6, 24, 48, and 72 h after the patient enters the PACU; (5) postoperative complications and adverse events; (6) postoperative hospital stay; (7) concentrations of brain-derived neurotrophic factor (BDNP), 5-hydroxytryptamine (5-HT), tumor necrosis factor (TNF-α) and interleukin-6, at 1, 3, and, 5 days post-surgery; and (8) the patient survival rate at 6 and 12 months post-surgery.DiscussionThe study hypothesis is that the postoperative HAMD-17 and VAS scores, incidence of postoperative adverse reactions, and concentration of serum markers BDNP, 5-HT, TNF-α, and IL-6 in the experimental group will be lower than those in the control group.Trial registrationClinicalTrials.gov ChiCTR2200066303.

Correlation between burst suppression and postoperative delirium in elderly patients: a prospective study.

To explore the correlation between intraoperative burst suppression (BS) and postoperative delirium (POD) in elderly patients, and provide more ideas for reducing POD in clinical. Ninety patients, aged over 60years, who underwent lumbar internal fixation surgery in our hospital were selected. General information of patients was obtained and informed consent was signed during preoperative visits. Patients were divided into burst suppression (BS) group and non-burst suppression (NBS) group by intraoperative electroencephalogram monitoring. Intraoperative systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were recorded, and the variation and minimum value were obtained by calculating. Hemoglobin (HGB), C-reactive protein (CRP), system immune inflammatory index (SII) at 24 and 72h after surgery, the incidence of postoperative adverse reactions, postoperative hospital stay, and total cost were recorded after operation. POD assessment was performed using CAM within 7days after surgery or until discharge. SPSS25.0 was used for statistical analysis. Compared with the NBS group, the number of elderly patients with high frailty level in BS group was more (P = 0.048). There is correlation between BS and POD (OR: 4.954, 95%CI 1.034-23.736, P = 0.045), and most of the POD patients in BS group behave as hyperactive type. The occurrence of intraoperative BS is associated with POD, and elderly patients with frailty are more likely to have intraoperative BS. BS can be used as a predictor of POD.

Clinical application of intubation-free anesthesia in radical resection of lung cancer.

In recent years, video-assisted thoracic surgery (VATS) has become increasingly widespread. However, the implementation of VATS requires the assistance with lung isolation techniques. Spontaneous breathing with laryngeal masks is also increasingly used in VATS. However, evidence on the characteristics of intubated anesthesia is insufficient. This study aimed to explore whether intubation-free anesthesia has more advantages than other intubation methods in the clinical setting. Patients with lung tumors who underwent VATS in our hospital between June 2022 and October 2022 were included in the study. Perioperative data of patients, including basic information, intraoperative hemodynamic changes, postoperative inflammatory indicators, and adverse reactions were obtained through the electronic medical record system. According to the protocol of airway management during anesthesia, participants were divided into the following groups: laryngeal mask with spontaneous breathing group (LMSB group), laryngeal mask combined with bronchial blocker group (LM + BB group), double-lumen tube group (DLT group), and tracheal tube combined with bronchial blocker group (TT + BB group). All data were analyzed using SPSS 25.0 software. At baseline, patients in the LMSB and LM + BB groups had a lower body weight (P = 0.024). Systolic blood pressure (SBP), diastolic BP (DBP), and heart rate (HR) were significantly higher in the DLT group than in the non-intubated group during surgery (SBP: T1 P = 0.048, T4 P = 0.021, T5 P ≤ 0.001, T6 P ≤ 0.001, T7 P = 0.004; DBP: T5 P ≤ 0.001, T6 P ≤ 0.001, T7 P ≤ 0.001; HR: T1 P = 0.021, T6 P ≤ 0.001, T7 P = 0.007, T8 P ≤ 0.001). The input fluid (P = 0.009), urine output (P = 0.010), surgery duration (P = 0.035), and procalcitonin levels (P = 0.024) of the DLT group were also significantly higher than those of the other groups. The recovery duration of the LMSB group was significantly longer (P = 0.003) and the incidence of postoperative adverse reactions, mainly atelectasis, was higher (P = 0.012) than those of the other groups. Although the intubation-free anesthesia has less stimulation during operation and less postoperative inflammatory response, it has obvious adverse reactions after operation, which may be not the best anesthesia scheme for radical resection of lung cancer in VATS. https://www.chictr.org.cn/showproj.html?proj=182767, identifier ChiCTR2200066180.

Clinical efficacy of minimally invasive puncture and drainage versus trepanation and drainage for chronic subdural hematoma: Systematic review and meta-analysis.

This study aimed to evaluate the clinical efficacy of minimally invasive puncture and drainage (MIPD) versus trepanation and drainage in the treatment of chronic subdural hematoma (CSDH). PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and Wanfang database were searched for studies on the treatment of CSDH by MIPD and trepanation and drainage. By reading the title, abstract and full text, and screening according to the inclusion and exclusion criteria, the qualified articles were confirmed. Subsequently, the literature quality was evaluated based on the Cochrane Handbook for Systematic Reviews of Interventions, and the data of the research subjects and the primary outcome measures were extracted for meta-analysis with RevMan 5.1 software. Ten articles were included, with a total of 1000 patients. According to the meta-analysis, the 2 groups showed no statistical difference in CSDH recurrence rate (P > .05). The operation time, intraoperative blood loss, and incidence of postoperative adverse reactions were lower and the cure rate was higher in the MIPD group compared with trepanation and drainage group (all P < .05). By drawing the funnel plot of the outcome measures with heterogeneity, it can be seen that the distribution on both sides of the funnel was basically symmetrical, suggesting a low deviation possibility of the analysis results and reliable reference significance of our findings. Compared with trepanation and drainage, MIPD has better clinical effects and higher safety in treating CSDH and can effectively reduce surgery-induced damage, which is worth popularizing in clinical practice.

Protective Efficiency Comparison of Direct and Remote Ischemic Preconditioning on Ischemia Reperfusion Injury of the Liver in Patients Undergoing Partial Hepatectomy.

Ischemia reperfusion injury greatly damages liver function and deteriorates the prognosis of patients undergoing partial hepatectomy. This study is to compare the protective efficiency of direct and remote ischemic preconditioning (DIPC and RIPC) on ischemia reperfusion injury of the liver in patients undergoing partial hepatectomy. 90 patients scheduled for partial hepatectomy were enrolled and randomly divided into control (n = 30), DIPC (n = 30), and RIPC (n = 30) groups. Baseline and surgery characteristics were collected, and ischemic preconditioning methods were carried out. Intraoperative hemodynamics, liver function and liver reserve capacity, oxidative stress, and inflammatory responses were measured, and the incidence of postoperative adverse reactions was calculated finally. 10 patients were excluded from the study, and finally, the eligible patients in three groups were 27, 28, and 25, separately. No significant differences were observed in baseline and surgery characteristics among the three groups. SBP and DBP were significantly higher after hepatic portal vein occlusion while they were significantly lower after surgery in the DIPC and RIPC groups compared with that in the control group, SBP and DBP were of great fluctuation at different time points in the control group while they showed much more stabilization in the DIPC and RIPC groups. ALT, AST, and TBIL were significantly decreased on days 1, 3, and 5 after surgery, and ICG R15 was significantly decreased while ICG K value and EHBF were significantly increased on day 1 after surgery in the DIPC and RIPC groups compared with that in the control group. Moreover, antioxidant enzyme SOD was increased, and inflammatory factors TNF-α and IL-1β were decreased 24 hours after surgery in the DIPC and RIPC groups compared with that in the control group. DIPC and RIPC also decreased hospital stays and the incidence of nausea, vomiting, and hypertension. DIPC and RIPC both alleviated ischemia reperfusion injury of the liver and reduced perioperative complications with similar protective efficiency in patients undergoing partial hepatectomy.

Combined acupuncture-medicine anesthesia used in thyroid surgery: A systematic review and meta-analysis.

Combined acupuncture-medicine anesthesia (CAMA) is extensively used in thyroid surgery in China. We conducted a systematic review and meta-analysis to assess the efficacy and safety of CAMA. We searched the China National Knowledge Infrastructure (CNKI), VIP database, WanFang database, PubMed, EMBASE, and the Cochrane Library for relevant literature. The term of literature was published before April 18, 2020, and there were no restrictions on publication language, region, or publication year. The inclusion criteria included a randomized controlled trial (RCT) of acupuncture combined with cervical plexus anesthesia. We used RevMan5.3 software for data analysis. If the chi-square test showed no significant heterogeneity (P > .10, I2 < 50%), we used the fixed-effect model to calculate risk ratio (RR) and mean difference. Otherwise, the random-effects model was used. Overall, 18 RCTs involving 1211 patients were included in the study. The anesthesia significant rate (ASR) in the transcutaneous electrical acupoint stimulation (TEAS) plus cervical plexus block anesthesia (CPBA) and electroacupuncture (EA) plus CPBA groups was significantly higher compared with the CPBA group (TEAS + CPBA: P < .001; EA + CPBA: P < .001). The pooled effect values of the intraoperative heart rate (HR) and mean arterial pressure (MAP) were significantly lower in both the TEAS + CPBA and EA + CPBA groups relative to the control group (HR: P = .05, P < .001; the MAP: P = .002, P < .001; respectively). Moreover, the postoperative adverse reaction was markedly lower in the experimental group than in the control group (RR = 0.30, P < .001), and there was no heterogeneity between the two groups (P = .71, I2 = 0%). Combined acupuncture-medicine anesthesia significantly increases the anesthesia significance rate, reduces the intraoperative heart rate, and blood pressure, and reduces the incidence of postoperative adverse reactions. However, more high-quality future studies should be conducted to validate the efficacy and safety of acupuncture combined anesthesia further.

Effect of Dexmedetomidine Combined with Dezocine for Cervical Plexus Block in Thyroid Surgery

This study mainly explores the clinical effects of dexmedetomidine and dezocine assisted ultrasound-guided nerve block in thyroid surgery. The data from a total of 72 patients who underwent thyroid surgery in our hospital were analyzed. All patients were given ultrasound-guided cervical plexus block anesthesia and divided into three groups. Group A (n=20) and group B (n=22) received dexmedetomidine and dezocine assisted anesthesia respectively, and group C (n=30) was given dexmedetomidine plus dezocine assisted anesthesia. Anesthesia time, operation time and other clinical indicators were compared among the three groups. The results showed that at 12 h and 24 h, group C had a lower degree of pain than groups A and B. The postoperative comfort score of group C was higher compared to groups A and B. The incidence of postoperative adverse reactions reported was lower in group C compared with the other two groups. The above outcomes shows that the combined use of dexmedetomidine and dezocine in ultrasound-guided assisted nerve block during thyroid surgery contributes to better clinical efficacy compared with their single use.

Effect of Dexmedetomidine on Recovery from Anesthesia in Gynecologic Laparoscopic Surgery

To evaluate the effect of dexmedetomidine on patient recovery from anesthesia in gynecologic laparoscopic surgery. A total of 74 patients who underwent gynecological laparoscopic surgery in our hospital between January 2020 and March 2022 were recruited and assigned via random method to receive either 0.6 μg/ kg of saline (observation group) or 0.6 μg/kg of dexmedetomidine (experimental group) before anesthesia induction during gynecologic laparoscopic surgery, with 37 cases in each group. Outcome measures included postoperative indices (recovery time, awakening time, orientation recovery time and extubation time), Ramsay scores, hemodynamic indices (heart rate, mean arterial pressure, pulse oximetry) at different time points and postoperative adverse events. Dexmedetomidine resulted in significantly shorter respiratory recovery time, awakening time, orientation recovery time and extubation time vs. control treatment (p<0.05). The Ramsay scores in the experimental group were significantly higher than those in the observation group (p<0.05) after treatment. Patients receiving dexmedetomidine showed lower heart rate and mean arterial pressure levels and higher pulse oximetry levels at extubation and 15 min after extubation than the controls (p<0.05). The incidence of postoperative adverse reactions in the experimental group was significantly lower than that in the observation group (p<0.05). Dexmedetomidine effectively shortens the recovery time of respiration, awakening time, recovery time of orientation and extubation time in patients undergoing gynecological laparoscopy and maintains the hemodynamic stability of the body without increasing the risk of postoperative adverse events in patients.

Investigation of the Effects of Large Bone Flap Craniotomy on Cerebral Hemodynamics, Intracranial Infection Rate, and Nerve Function in Patients with Severe Craniocerebral Trauma.

In order to explore the clinical value of large bone flap craniotomy, the effects of standard large bone flap craniotomy on cerebral hemodynamic indexes, incidence of postoperative intracranial infection, and neurological function in patients with severe craniocerebral trauma are investigated. 89 patients with severe craniocerebral trauma admitted from January 2020 to June 2021 are analyzed retrospectively. All patients are divided into a large craniotomy group (n = 45) and control group (n = 44) according to different surgical methods. The large craniotomy group is treated with large craniotomy decompression, and the control group is treated with traditional craniotomy decompression. The incidence of intracranial infection in each group is recorded, and NIHSS is applied to observe the neurological function recovery of 2 groups before and 1 month after operation. Besides, the patients are followed up after surgery and the Kaplan–Meier survival curve is obtained to compare the survival rate of patients in the two groups. It is clearly evident that the two surgical methods have certain clinical efficacy in the treatment of patients with severe craniocerebral trauma. Comparatively, the large craniotomy can further improve brain blood supply and improve neurological function recovery. Also, it can obtain low incidence of postoperative adverse reactions and intracranial infection.
