Postoperative Day In Patients Research Articles

Red blood cell count in cerebrospinal fluid was correlated with inflammatory markers on the seventh postoperative day and all associated with the outcome of aneurysmal subarachnoid hemorrhage patients.

Exploring factors associated with the outcome of patients with aneurysmal subarachnoid hemorrhage (aSAH) has become a hot focus in research. We sought to investigate the associations of inflammatory markers and blood cell count in cerebrospinal fluid with the outcome of aSAH patients. We carried a retrospective study including 200 patients with aSAH and surgeries. The associations of neutrophil, lymphocyte, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), systemic immune inflammation index (SII), system inflammation response index (SIRI), and blood cell count in cerebrospinal fluid on the 1st and 7th postoperative days with the outcome of aSAH patients were investigated by univariate analysis and multivariate logistic regression model. According to the modified Rankin scale (mRS) score, there were 147 patients with good outcome and 53 patients with poor outcome. The neutrophil, NLR, SIRI, and SII levels on the seventh postoperative day in patients with poor outcome were all significantly higher than patients with good outcome, P < 0.05. The multivariate logistic regression model including inflammatory markers and blood cell counts in cerebrospinal fluid on the 1st postoperative day confirmed that red blood cell count in cerebrospinal fluid (≥177 × 109/L; OR: 7.227, 95% CI: 1.160-45.050, P = 0.034) was possibly associated with poor outcome of aSAH patients, surgical duration (≥169 min), Fisher grade (III-IV), hypertension, and infections were also possibly associated with the poor outcome. The model including inflammatory markers and blood cell counts in cerebrospinal fluid on the 7th postoperative day confirmed that red blood cell count in cerebrospinal fluid (≥54 × 109/L; OR: 39.787, 95% CI: 6.799-232.836, P < 0.001) and neutrophil-lymphocyte ratio (≥8.16; OR: 6.362, 95% CI: 1.424-28.428, P = 0.015) were all possibly associated with poor outcome of aSAH patients. The NLR (r = 0.297, P = 0.007) and SIRI (r = 0.325, P = 0.003) levels were all correlated with the count of red blood cells in cerebrospinal fluid. Higher neutrophil-lymphocyte ratio and higher red blood cell count in cerebrospinal fluid were all possibly associated with poor outcome of patients with aneurysmal subarachnoid hemorrhage. However, we need a larger sample study.

Individualized Perioperative Hemodynamic Management Using Hypotension Prediction Index Software and the Dynamics of Troponin and NTproBNP Concentration Changes in Patients Undergoing Oncological Abdominal Surgery.

Abdominal oncologic surgeries pose significant risks due to the complexity of the surgery and patients' often weakened health, multiple comorbidities, and increased perioperative hazards. Hypotension is a major risk factor for perioperative cardiovascular complications, necessitating individualized management in modern anesthesiology. This study aimed to determine the dynamics of changes in troponin and NTproBNP levels during the first two postoperative days in patients undergoing major cancer abdominal surgery with advanced hemodynamic monitoring including The AcumenTM Hypotension Prediction Index software (HPI) (Edwards Lifesciences, Irvine, CA, USA) and their association with the occurrence of postoperative cardiovascular complications. A prospective study was conducted, including 50 patients scheduled for abdominal cancer surgery who, due to the overall risk of perioperative complications (ASA class 3 or 4), were monitored using the HPI software. Hypotension was qualified as at least one ≥ 1 min episode of a MAP < 65 mm Hg. Preoperatively and 24 and 48 h after the procedure, the levels of NTproBNP and troponin were measured, and an ECG was performed. We analyzed data from 46 patients and found that 82% experienced at least one episode of low blood pressure (MAP < 65 mmHg). However, the quality indices of hypotension were low, with a median time-weighted average MAP < 65 mmHg of 0.085 (0.03-0.19) mmHg and a median of 2 (2-1.17) minutes spent below MAP < 65 mmHg. Although the incidence of perioperative myocardial injury was 10%, there was no evidence to suggest a relationship with hypotension. Acute kidney injury was seen in 23.9% of patients, and it was significantly associated with a number of episodes of MAP < 50 mmHg. Levels of NTproBNP were significantly higher on the first postoperative day compared to preoperative values (285.8 [IQR: 679.8] vs. 183.9 [IQR: 428.1] pg/mL, p < 0.001). However, they decreased on the second day (276.65 [IQR: 609.4] pg/mL, p = 0.154). The dynamics of NTproBNP were similar for patients with and without heart failure, although those with heart failure had significantly higher preoperative concentrations (435.9 [IQR: 711.15] vs. 87 [IQR: 232.2] pg/mL, p < 0.001). Patients undergoing laparoscopic surgery showed a statistically significant increase in NTproBNP. This study suggests that advanced HPI monitoring in abdominal cancer surgery effectively minimizes intraoperative hypotension with no significant NTproBNP or troponin perioperative dynamics, irrespective of preoperative heart failure.

Associations of neutrophil to lymphocyte ratio and red cell distribution width on different days with the prognosis of aneurysmal subarachnoid hemorrhage patients.

The associations of neutrophil to lymphocyte ratio (NLR) and red cell distribution width (RDW) with the prognosis of aneurysmal subarachnoid hemorrhage (aSAH) patients were confirmed in a few studies. But NLR and RDW levels in most of these studies were on admission. Here we carried 1 retrospective study including 150 patients with aSAH who underwent surgeries in the First Affiliated Hospital of Yangtze University from January 2020 to February 2023 to explore the associations on the preoperative day, the first (1st), third (3rd), and seventh (7th) postoperative days. The level of RDW on the 3rd postoperative day and level of NLR on the 7th postoperative day in patients with poor prognosis were significantly higher than patients with good prognosis. The results of multivariate logistic analysis also confirmed the associations of RDW on the 3rd postoperative day (OR = 16.785, 95% CI: 4.077-69.107, P < .001) and NLR on the 7th postoperative day (OR = 8.399, 95% CI: 2.167-32.544, P = .002) with prognosis of aSAH patients. The results of receiver operating characteristic curve showed that cutoff values of RDW and NLR for predicting the prognosis in aSAH patients were 13.05% and 6.97, respectively. Higher RDW on the 3rd postoperative day and NLR on the 7th postoperative day were possibly associated with poor prognosis of aSAH patients. We should pay attention to the RDW and NLR levels during different hospitalization periods, especially in the short postoperative period. Moreover, the cutoff values for predicting prognosis need to be validated in larger-sample studies.

Systemic inflammation response index (SIRI) on the 3rd postoperative day are associated with severe pneumonia in cerebral hemorrhage patients: A single-center retrospective study.

Inflammatory response was involved in the progression of cerebral hemorrhage. We sought to explore the associations of easily obtained inflammatory indicators including blood cell counts and the ratios of different blood cells counts with pneumonia and severe pneumonia in cerebral hemorrhage patients. We carried 1 retrospective study including 200 patients with cerebral hemorrhage and surgeries. The associations of neutrophils, lymphocytes, monocytes, platelets, systemic immune inflammation index (SII), systemic inflammation response index (SIRI), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) with pneumonia and severe pneumonia in cerebral hemorrhage patients were estimated by univariate analysis and multivariate logistic regression model. Among the 200 patients included, there were a total of 163 (81.5%) had pneumonia after surgeries. Among 163 cerebral hemorrhage patients with pneumonia, 60 (36.8%) cases were evaluated as severe pneumonia. The level of SIRI on the 1st postoperative day in patients with severe pneumonia was higher than non-severe pneumonia (10.89 ± 12.10 × 109/L vs 7.14 ± 9.76 × 109/L, P = .003). The level of SIRI on the 3rd postoperative day in patients with severe pneumonia was more significantly higher (7.98 ± 7.46 × 109/L vs 4.10 ± 3.74 × 109/L, P < .001). The results of multivariate analysis showed that SIRI level on the 3rd postoperative day (>6.5 × 109/L) was associated with severe pneumonia in cerebral hemorrhage patients (OR: 4.409, 95% CI: 1.799-10.806, P = .001). SIRI was possibly a superior predictor for severe pneumonia in cerebral hemorrhage patients compared with other inflammatory indicators. On the one hand, we intend to validate the cutoff value of SIRI for predicting severe pneumonia in larger samples and multicenter studies. On the other hand, we also intend to use this index to guide the choice of antibacterial drugs in order to better benefit patients.

Pain management following simultaneous bilateral total knee arthroplasty: genicular nerve blockade versus periarticular injection

The aim of the present study was to investigate whether the analgesic solution prepared for periarticular injection (PAI) could be utilized as a genicular nerve blockade (GNB) agent in bilateral knee arthroplasty, and to assess the pain control efficacy of this approach in comparison with PAI. This was a retrospective cohort in which patients undergoing simultaneous bilateral total knee arthroplasty (TKA) were evaluated. Thirty patients were enrolled. The standard PAI was used for one knee, while the PAI solution was applied in the form of GNB to the other. Visual Analog Scale (VAS) pain scores were measured and recorded separately for each knee, at rest (static) and during exercise (dynamic). Active range of joint motion (JRM) for both knee joints was measured preoperatively, at postoperatively. Compared to the PAI group, the GNB group had lower VAS scores at 2 and 8 hours (p = 0.030 and p &lt; 0.001, respectively). The GNB group also had lower dynamic VAS scores at 2, 8, and 24 hours (p = 0.009, p &lt;0.001 and p&lt;0.001, respectively). Static and dynamic VAS measurements did not demonstrate any differences between groups (GNB vs. PAI) at 48 hours and 30 days (p&gt;0.05). When the reduction in VAS scores was assessed, we found that the decrease in both scores was significantly greater in the PAI group compared to the GNB group (p&lt;0.001, for both). There were no significant differences between the groups with regard to drainage volume, complications and JRM (p&gt;0.05). GNB was found to be more effective for pain control throughout the first postoperative day in patients who underwent simultaneous bilateral TKA.

Seroma prevention with topical Abnobaviscum sclerotherapy following excision of giant cervical lipoma.

Lipomas are common benign tumors of mesenchymal origin that are composed of mature adipocytes. Giant lipomas have a diameter ≥ 10 cm in one or more dimensions or weigh at least 1,000 g. The surgical excision of a giant lipoma requires extensive dissection, increasing the risk of a seroma, which can cause surgical site complications such as wound infection and necrosis. Sclerotherapy with Abnobaviscum (Viscum album extract) is a relatively new technique used to reduce malignant pleural effusion. In this study, we evaluated the effectiveness of prophylactic sclerotherapy using Abnobaviscum to decrease seroma after giant lipoma excision. We conducted a retrospective medical record review of patients who underwent surgical excision for giant lipoma of the neck from January 2019 to December 2022. Sclerotherapy was performed on the first postoperative day in patients who consented to the procedure, and Abnobaviscum was instilled through the existing Hemovac drain. We compared the clinical course between those who underwent postoperative sclerotherapy and those who did not. Among the 30 patients who underwent giant lipoma excision, we applied sclerotherapy with Abnobaviscum to 15 patients. The average time from surgery to Hemovac removal was statistically shorter in patients who underwent sclerotherapy (p= 0.004). Furthermore, seroma formation was significantly reduced in patients receiving sclerotherapy (p= 0.003). In patients undergoing giant lipoma excision, sclerotherapy using Abnobaviscum helps reduce postoperative seroma formation during the initial postoperative period. It can be an excellent method to reduce complications related to seroma and attenuate patients' postoperative burden.

Would surgical Apgar score be useful to predict postoperative complications after proximal femoral fracture surgery? - A retrospective cohort study.

The surgical Apgar score (SAS) is a perioperative risk evaluation score, which considers intraoperative minimum heart rate, minimum mean arterial pressure and estimated blood loss. Although validated in multiple surgical fields, SAS remains quite controversial in the orthopedic one. The main purpose of this study was to investigate if SAS relates with the occurrence of complications during the first 30-days after proximal femoral fracture surgery. Retrospective study including all consecutive patients submitted to proximal femoral fracture surgery between January and July 2019. Patients with no information about SAS were excluded. Patients were divided in two groups, based on the occurrence of complications during the first 30 post-operative days and their SAS calculated. Receiver operating characteristic (ROC) curves were used to assess SAS power as a predictive model of complications. Forty-two percent (n=76) of the 181 patients included in the study developed complications during the first 30 postoperative days. Eight patients (4,4%) died during that period. The patient's mean age was 79 years and 30,9% (n=56) were men. Heart failure, pacemaker use, chronic kidney disease, chronic obstructive pulmonary disease and dementia were significantly associated with post-operative morbidity. There was no significant correlation between SAS and the occurrence of complications during the first 30 postoperative days. The AUC of SAS as a predictive model for postoperative complications after proximal femoral fracture surgery was 0,522, being insufficient to be considered an accepted model of prediction. Based on this study, we conclude that SAS is not predictive of the development of complications in the first 30 post-operative days in patients submitted to proximal femoral fracture surgery. However, other clinical factors have been identified as associated with postoperative morbidity. In the future, prospective-based studies with higher samples may better clarify the role of SAS in this context.

Dexmedetomidine administration during brain tumour resection for prevention of postoperative delirium: a randomised trial

BackgroundDelirium is common, especially after neurosurgery. Dexmedetomidine might reduce delirium by improving postoperative analgesia and sleep quality. We tested the primary hypothesis that dexmedetomidine administration during intracerebral tumour resection reduces the incidence of postoperative delirium. MethodsThis randomised, double-blind, placebo-controlled trial was conducted in two tertiary-care hospitals in Beijing. We randomised 260 qualifying patients to either dexmedetomidine (n=130) or placebo (n=130). Subjects assigned to dexmedetomidine were given a loading dose of 0.6 μg kg−1 followed by continuous infusion at 0.4 μg kg−1 h−1 until dural closure; subjects in the placebo group were given comparable volumes of normal saline. The primary outcome was the incidence of delirium, which was assessed with the Confusion Assessment Method twice daily during the initial 5 postoperative days. ResultsThe average (standard deviation) age of participating patients was 45 (12) yr, duration of surgery was 4.2 (1.5) h, and patients assigned to dexmedetomidine were given an average of 126 (45) μg of dexmedetomidine. There was less delirium during the initial 5 postoperative days in patients assigned to dexmedetomidine (22%, 28 of 130 patients) than in those given placebo (46%, 60 of 130 patients) with a risk ratio of 0.51 (95% confidence interval: 0.36–0.74, P<0.001). Postoperative pain scores with movement, and recovery and sleep quality were improved by dexmedetomidine (P<0.001). The incidence of safety outcomes was similar in each group. ConclusionsProphylactic intraoperative dexmedetomidine infusion reduced by half the incidence of delirium during the initial 5 postoperative days in patients recovering from elective brain tumour resection. Clinical trial registrationNCT04674241.

High-dose preoperative glucocorticoid for prevention of emergence and postoperative delirium in liver resection: A double-blinded randomized clinical trial substudy.

BackgroundEmergence delirium (ED) and postoperative delirium (POD) are associated with increased morbidity and mortality and occur in up to one‐third of patients undergoing major non‐cardiac surgery, where the underlying pathogenesis is multifactorial, including increased inflammation. We aimed to assess the effect of pre‐operative high‐ versus low‐dose glucocorticoid on the occurrence of ED and POD.MethodsThis was a substudy from a randomized, double‐blinded clinical trial. Patients ≥18 years, undergoing open liver resection were randomized 1:1 to high‐dose (HD, 10 mg/kg methylprednisolone) or low‐dose (LD, 8 mg dexamethasone) glucocorticoid and assessed for ED and POD for a maximum of 4 days during hospitalization. The 3‐min Diagnostic Interview for CAM‐defined delirium (3D‐CAM) was used for assessment, 15 and 90 min after arrival in the post‐anesthesia care unit (PACU), and subsequently once daily in the ward.ResultsFifty‐three patients were included in this secondary substudy (26 HD‐group and 27 LD‐group). ED occurred in n = 5 HD versus n = 6 LD patients 15 min after PACU arrival. At 90 min after PACU arrival, 4 patients had ED, all from LD‐group, and resulted in significantly longer PACU admission, 273 versus 178 min in ED versus Non‐ED patients. During the first 4 days in the ward, n = 5 patients had at least one occurrence of POD, all from LD‐group.ConclusionsThe primary finding of the current substudy was a lower occurrence of ED/POD in the PACU 90 min after arrival and during the first four postoperative days in patients receiving high‐dose glucocorticoid compared with patients receiving low‐dose glucocorticoid. The two study groups were not evenly balanced concerning known explanatory factors, i.e., age and size of surgery, which calls for larger studies to elucidate the matter.

Efficacy of Submucosal Dexamethasone Injection on Postoperative Adverse Outcomes Following Third Molar Surgery

Introduction: The most common dento-alveolar procedure is surgical removal of an impacted third molar, which is associated with post-operative pain, swelling, and trismus.&#x0D; Objective: To determine the effect of submucosal dexamethasone injection on the post-operative outcomes in third molar surgeries.&#x0D; Materials and Methods: It was a descriptive study conducted in Department of Oral &amp; Maxillofacial Surgery, Liaquat College of Medicine &amp; Dentistry, Karachi between November 7, 2019 to May 6, 2020. All patients who fulfilled the inclusion criteria and visited to LCMD, Karachi were included in the study. Informed consent was taken after explaining the procedure, risks and benefits of the study. In our study, all the patients (n=65) received 4mg submucosal dexamethasone injection. The duration of surgery was recorded with postoperative outcomes in terms of pain, trismus and swelling were measured on 3rd and 7th day. All the collected data were entered into the proforma and used electronically for research purpose.&#x0D; Results: The mean SD of age was 25.9 ± 7.2 years. Right side surgery was documented in 39 (60%) patients, while left side surgery was documented in 26 (40%) patients. On the third and seventh day, the mean SD of VAS pain score was (5.9 ± 3.2), (3.8 ± 4.4), swelling was (2.5 ± 1.1), (0.9 ± 0.6) mm, and trismus was (16.9 ± 9.7), (11.8 ± 9.1) mm, respectively.&#x0D; Conclusion: It is to be concluded that a significant difference in outcomes was observed between the third and seventh post-operative days in patients who had submucosal dexamethasone injections in third molar surgeries.

Intravenous tranexamic acid reduce postoperative drainage and pain after open elbow arthrolysis: a randomized controlled trial.

Open elbow arthrolysis (OEA), which has become an established treatment for post-traumatic elbow stiffness (PTES), requires complete release of contracture tissue and wide excision of ectopic bone, which results in extensive bleeding. The aim of the present study is to evaluate the efficacy of intravenous tranexamic acid (TXA) on postoperative drainage, calculated blood loss, and early clinical outcomes in patients undergoing OEA. A double-blind, randomized, placebo-controlled trial including 96 patients undergoing OEA was undertaken. Patients received intravenously either 100 mL saline (placebo group, n = 48), or 100 mL saline plus 1 g TXA (TXA group, n = 48) before skin incision. The primary outcome was the drainage volume on postoperative days (PODs) 1-3. Secondary outcomes included the calculated blood loss, elbow pain score measured by visual analog scale (VAS), elbow function valued by Mayo Elbow Performance Score (MEPS), and rate of complications after OEA. Mean total postoperative drainage volume (TXA group: 182 mL vs. placebo group: 214 mL, P = .003) and mean calculated total blood loss (TXA group: 582 mL vs. placebo group: 657 mL, P = .004) were significantly lower in the TXA group. No transfusions were necessary in either group. Mean VAS pain scores in elbow motion showed marked differences between both groups on POD 1 (TXA: 5 vs. placebo: 6, P = .003) and POD 2 (TXA: 4 vs. placebo: 5, P = .023) but not in other postoperative time points. No differences were detected in complications, such as pin-related infection, hematoma, new or exacerbation of ulnar nerve symptoms, and recurrent heterotopic ossification. At the 6-month follow-up, no statistical differences were found between the 2 groups with respect to the elbow functions including range of motion, VAS score, and MEPS. Intravenous administration of TXA significantly decreased the postoperative drainage volume and the total estimated blood loss and alleviated the elbow pain with motion during early postoperative days in patients undergoing OEA.

The Impact of Unilateral and Bilateral Eversion Carotid Endarterectomy on Postoperative Hemodynamic Parameters.

Background:Carotid endarterectomy (CEA) is an effective and safe treatment of stenosed carotid arteries, and is a preventive operation with well-defined indications. It is associated with a loss of the baroreceptor reflex and postoperatively increased hemodynamic parameters.Objective:The aim of the study was to confirm the sensitivity of baroreceptors and the impact on arterial pressure and heart rate in unilateral and bilateral eversion carotid endarterectomies.Methods:A retrospective study was conducted with 30 patients treated with E-CEA in local anesthesia at the Clinic for cardiovascular surgery from December 2019 to May 2021, due to stenosis of the carotid arteries. Patients were divided into two groups: 15 patients in group A (patients with unilateral E-CEA; 15 patients in group B: patients with bilateral E-CEA).Results:Out of the total of 30 patients included in the research, 15 patients in groups A and B respectively, there were no statistically significant differences in regards to gender (p= 0,245) and preoperative risk factors: smoking (p=0,449); hypertension (p=0,388); diabetes (p= 0,714); hyperlipidemia (p=0.388), coronary disease (p=0.461) and symptomatic stenosis of the carotid arteries (p=0.449). Noted were the statistically significant differences in values of systolic and diastolic pressure on the 3rd postoperative days in patients with bilateral E-CEA (p=0,001; p=0,001), a statistically significant difference in the heart rate was not found in the analyzed groups in the postoperative period (p=0,225; p=0,994).Conclusion:This study identified statistically significant differences in values of systolic and diastolic pressure in the early postoperative period. In his period, early detection and correction of these hemodynamic disorders are needed.

P136 COMPARISON OF TOTALLY MINIMALLY AND HYBRID IVOR LEWIS ESOPHAGECTOMY FOR CANCER OF DISTAL ESOPHAGUS AND ESOPHAGOGASTRIC JUNCTION

Abstract Aim Aim of this retrospective study is the comparison of the short-terms outcomes and QoL of Hybrid Ivor Lewis (HIL) and Totally Minimally Invasive Ivor Lewis (TMIIL). Background &amp; Methods Minimally invasive techniques for esophagectomy represents a challenging procedure with aiming to decrease cardiopulmonary complications and guarantee better quality of life (QoL) compared to open techniques, without compromising oncological radicality. Patients with cancer of distal esophagus and EGJ were included into (HIL) and (TMIIL) groups in the period January 2017 – March 2019. General features, intraoperative and postoperative results were analyzed. For all the patients a feeding jejunostomy was performed. The surgical radicality and number of resected nodes were also evaluated. QoL was determined preoperatively, at 7 and 90 days postoperatively with EORTC QLQ-C30 questionnaire. Results Eighteen and 24 patients were submitted to TMIIL and HIL respectively. General features were similar in the two groups. Median intervention duration was 360 minutes [range: 240-420] in TMIIL group and 335 minutes [range: 150-400] for HIL group (p=0.0647). Median blood losses were similar for TMIIL and HIL group, 100 ml [range:50-400] and 175 ml [50-350] respectively (p=0.0831). No differences were observed in terms of postoperative complications CD≥2. One exitus occurred in HIL group (CD=5), none in TMIIL group (p=n.s). No differences were evidenced for median number of lymphnodes harvested in the two group as well for rate of R0 and R1 resections. Results obtained from the QoL questionnaires evidenced a reduction of postoperative pain during the first 7 postoperative day for patients in the TMIIL group compared to HIL; these data were confirmed by the analysis conducted on postoperative day 90, as well for the global health status, physical functioning and role functioning. Conclusion Our experience evidenced TMIIL esophagectomy seems to give the similar results, of HIL influencing positively the QoL within 90-day after surgery. Duration of surgery and anastomotic leaks are the key elements influencing the learning curve. Randomized controlled trials are necessary to confirm the good results obtained and to give recommendations to avoid a high rate of complications

“Continuous” and “one-shot” serratus plane block in uniportal video-assisted thoracic surgery: preliminary results

Background: Post-operative pain management has always been a fundamental topic in thoracic surgery. Common analgesic techniques may have important side effects. Minimally invasive surgery provides reduction of post-operative pain if compared with open thoracic surgery, but it doesn’t solve the issue. The aim of this study was to evaluate the role of “serratus plane block” (SPB) in uniportal video-assisted thoracic surgery (U-VATS) and to compare the effectiveness of “continuous” vs . “one-shot” administration of it. Methods: Forty-four patients undergoing U-VATS surgery were involved in this study: SPB was performed in 22 patients by using a catheter that was positioned above the serratus to obtain a “continuous” SPB through a local continuous application of the anesthetic for 72 hours after surgery, a “one-shot” SPB in other 22 patients, applying a single dose of the anesthetic drug on the serratus superficial fascia before the end of the surgical time. Results: There was a statistical significance since the first post-operative day for patients in the continuous SPB (cSPB) group, who had better pain control compared with the “one-shot” SBP (osSBP) group. Patients in the cSPB required less systemic pain therapy administration. Conclusions: cSPB performed after U-VATS surgery seems to offer patients gain in good level of pain tolerance with no observed side effects.

Preoperative sleep disruption and postoperative functional disability in lung surgery patients: a prospective observational study.

Our aims were to evaluate the prevalence of preoperative acute sleep disruption in the hospital and to assess perioperative sleep quality and the effects of acute sleep disruption on postoperative functional recovery in a surgical setting. This prospective observational study included 24 patients aged ≥20years who underwent video-assisted thoracoscopic surgical lobectomy for lung cancer under general anesthesia at a tertiary hospital in Japan between October 2016 and May 2017. Actigraphy was performed for 7days in the hospital, including the night before surgery. We defined acute sleep disturbance as less than 85% preoperative sleep efficiency and analyzed its effect on postoperative functional disability using the 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) and Mann-Whitney U testing. The perioperative change in sleep efficiency was compared using a Dunn analysis. A high score on the WHODAS 2.0 is indicative of impaired function. Nineteen (79.1%) patients had low sleep efficiency in the hospital prior to surgery. Three months after surgery, the 12-item WHODAS 2.0 score was higher in patients with acute sleep disturbance than in those without it (38.8 versus 33.3, p = 0.02, effect size 0.5). Sleep efficiency decreased significantly on the 5th postoperative day in patients with acute sleep disturbance. Our results showed a high prevalence of acute sleep disturbance. Patients with acute sleep disruption had low postoperative sleep efficiency and impaired functional ability three months after surgery.

Early exercise pulmonary diffusing capacity of carbon monoxide after anatomical lung resection: a word of caution for fast-track programmes.

In healthy individuals, increasing pulmonary blood flow during exercise also increases the % of the diffusing capacity of the lungs for carbon monoxide (DLCO%), but its evolution after lung resection is unknown. In this study, our goal was to measure changes in exercise DLCO% during the first 3 days after anatomical lung resection. We performed a prospective observational study on consecutive patients with non-small-cell lung cancer scheduled for anatomical resection, except pneumonectomy, during a 6-month period. Patients underwent measurement of the DLCO% by a single-breath technique adjusted by the concentration of haemoglobin-before and after standardized exercise the day before and 3 consecutive days after surgery. The delta (Δ) variation (basal versus exercise) was calculated. The number of functioning resected segments was calculated by bronchoscopy. Postoperative pain and pleural air leak were estimated using a visual analogue scale and graduated conventional pleural drainage systems, respectively, and their influence on ΔDLCO each postoperative day was evaluated by linear regression analysis. Fifty-seven patients were included. The visual analogue scale of pain and pleural air leaks were not correlated to Δ values (model R2: 0.0048). The evolution of Δ values during 3 postoperative days showed a progressive recovery of values, but on the third day, DLCO% capacity during exercise was still impaired (P < 0.01), especially in patients who underwent a resection of more than 3 functioning segments. Physiological increase in DLCO% during exercise is still impaired on the third postoperative day in patients undergoing resection of more than 3 functioning pulmonary segments. This fact should be considered before discharging those patients after anatomical lung resection.

Postoperative microcirculatory perfusion and endothelial glycocalyx shedding following cardiac surgery with cardiopulmonary bypass.

SummaryWe investigated microcirculatory perfusion disturbances following cardiopulmonary bypass in the early postoperative period and whether the course of these disturbances mirrored restoration of endothelial glycocalyx integrity. We performed sublingual sidestream dark field imaging of the microcirculation during the first three postoperative days in patients who had undergone on‐pump coronary artery bypass graft surgery. We calculated the perfused vessel density, proportion of perfused vessels and perfused boundary region. Plasma was obtained to measure heparan sulphate and syndecan‐1 levels as glycocalyx shedding markers. We recruited 17 patients; the mean (SD) duration of non‐pulsatile cardiopulmonary bypass was 103 (18) min, following which 491 (29) ml autologous blood was transfused through cell salvage. Cardiopulmonary bypass immediately decreased both microcirculatory perfused vessel density; 11 (3) vs. 16 (4) mm.mm−2, p = 0.052 and the proportion of perfused vessels; 92 (5) vs. 69 (9) %, p < 0.0001. The proportion of perfused vessels did not increase after transfusion of autologous salvaged blood following cardiopulmonary bypass; 72 (7) %, p = 0.19 or during the first three postoperative days; 71 (5) %, p < 0.0001. The perfused boundary region increased after cardiopulmonary bypass; 2.2 (0.3) vs. 1.9 (0.3) μm, p = 0.037 and during the first three postoperative days; 2.4 (0.3) vs. 1.9 (0.3) μm, p = 0.003. Increased plasma heparan sulphate levels were inversely associated with the proportion of perfused vessels during cardiopulmonary bypass; R = −0.49, p = 0.02. Plasma syndecan‐1 levels were inversely associated with the proportion of perfused vessels during the entire study period; R = −0.51, p < 0.0001. Our study shows that cardiopulmonary bypass‐induced acute microcirculatory perfusion disturbances persist in the first three postoperative days, and are associated with prolonged endothelial glycocalyx shedding. This suggests prolonged impairment and delayed recovery of both microcirculatory perfusion and function after on‐pump cardiac surgery.

The Effect of Cigarette Smoking on Wound Complications After Single-Level Posterolateral and Interbody Fusion for Spondylolisthesis

To evaluate the impact of cigarette smoking on the development of wound complications, including wound dehiscence, superficial infection, deep infection, or organ space infection, within the first 30 postoperative days in patients undergoing surgery for spondylolisthesis. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for the years 2012-2014 was used to identify adult patients who underwent single-level posterolateral fusion (PLF) or interbody fusion for spondylolisthesis. Wound complications occurring within 30 days were compared between current smokers and nonsmokers. A total of 1688 patients who underwent single-level PLF or interbody fusion for spondylolisthesis were identified, among whom 271 were current smokers (16.1%). The overall wound complication rate was 3.3% for smokers versus 1.8% for nonsmokers (P= 0.095). When stratified by operative technique, the rate of wound complications was not significantly different between smokers and nonsmokers undergoing PLF (2.4% vs. 2.6%; P= 1.00); however, smokers who underwent interbody fusion were more likely to experience a wound complication compared with nonsmokers undergoing interbody fusion (3.7% vs. 1.3%; P= 0.028). On multivariate analysis, smoking was an independent predictor of organ/space infection irrespective of fusion technique used (odds ratio, 15.4; 95% confidence interval, 1.34-175.4; P= 0.028). The rate of wound complications was not higher in smokers undergoing PLF alone, but was significantly higher in smokers who underwent interbody fusion. However, multivariate analysis identified smoking as an independent predictor of organ/space infection irrespective of fusion technique used.
