Project description:BackgroundPostoperative pulmonary complications (PPCs) are a major cause of morbidity and mortality after open abdominal surgery. Optimized perioperative lung expansion may minimize the synergistic factors responsible for the multiple-hit perioperative pulmonary dysfunction. This ongoing study will assess whether an anesthesia-centered bundle focused on perioperative lung expansion results in decreased incidence and severity of PPCs after open abdominal surgery.MethodsProspective multicenter randomized controlled pragmatic trial in 750 adult patients with at least moderate risk for PPCs undergoing prolonged (≥2 hour) open abdominal surgery. Participants are randomized to receive either a bundle intervention focused on perioperative lung expansion or usual care. The bundle intervention includes preoperative patient education, intraoperative protective ventilation with individualized positive end-expiratory pressure to maximize respiratory system compliance, optimized neuromuscular blockade and reversal management, and postoperative incentive spirometry and early mobilization. Primary outcome is the distribution of the highest PPC severity by postoperative day 7. Secondary outcomes include the proportion of participants with: PPC grades 1-2 through POD 7; PPC grades 3-4 through POD 7, 30 and 90; intraoperative hypoxemia, rescue recruitment maneuvers, or cardiovascular events; and any major extrapulmonary postoperative complications. Additional secondary and exploratory outcomes include individual PPCs by POD 7, length of postoperative oxygen therapy or other respiratory support, hospital resource use parameters, Patient-Reported Outcomes Measurements (PROMIS®) questionnaires for dyspnea and fatigue collected before and at days 7, 30 and 90 after surgery, and plasma concentrations of lung injury biomarkers (IL6, IL-8, RAGE, CC16, Ang-2) analyzed from samples obtained before, end of, and 24 hours after surgery.DiscussionParticipant recruitment for this study started January 2020; results are expected in 2024. At the conclusion of this trial, we will determine if this anesthesia-centered strategy focused on perioperative lung expansion reduces lung morbidity and healthcare utilization after open abdominal surgery.Trial registrationClinicalTrial.gov NCT04108130.

Project description:BackgroundNumerous studies have shown that improving oral hygiene contributes to a reduction in the risk of postoperative complications in patients with head and neck cancer, cardiac disease, and esophageal cancer. However, the beneficial standard for oral management procedures during the perioperative period has not yet been established. Therefore, our aim was to determine whether or not their innovative oral management intervention contributed to a reduction in postoperative complications in lung cancer.MethodsWe performed a retrospective analysis of medical records of patients who underwent lung cancer surgery with lobectomy and pneumonectomy at Kyorin University Hospital. Patients were divided into 2 groups: a perioperative oral management intervention group that underwent lung cancer surgery from April 2016 to March 2018 (n = 164), and a control group without oral management that underwent surgery from April 2014 to March 2016 (n = 199). In particular, our oral management procedure emphasized oral mucosa stimulation to induce saliva discharge as in gum chewing, rather than simply using teeth brushing to reduce oral microbiome. Therefore, our oral management procedure is different from traditional oral care.ResultsThis study demonstrated that our oral management practice was associated with a decline in the occurrence of postoperative pneumonia (odds ratio, 0.184; 95% CI, 0.042-0.571; P = .009), postoperative hospital stay duration (β coefficient, -4.272; 95% CI, -6.390 to -2.155; P < .001) and Clavian-Dindo classification grade II or above (odds ratio, 0.503; 95% CI, 0.298-0.835; P = .009).ConclusionsWe propose an innovative new strategy using their unique oral management procedure to reduce postoperative complications resulting from pulmonary resection.

Project description:Background and aimsRespiratory system compliance (Crs) is a simple indicator of lung flexibility. However, it remains unclear whether a low Crs during anesthesia induction (iCrs) is associated with an increased risk of postoperative mechanical ventilation.MethodsThis retrospective observational study was conducted using a local database. All mechanically ventilated postoperative ICU patients were included in this study. The duration of postoperative mechanical ventilation, length of hospital stay, and in-hospital mortality were compared between the low iCrs group (<25% of distribution) and the normal iCrs group.ResultsA total of 315 patients were classified into the low iCrs (<39 mL/cmH2O) group (n = 78) or the normal iCrs group (n = 237). Low iCrs was associated with a higher chance of mechanical ventilation in 28 days (log-rank test, p < 0.001). The duration of hospital stay was similar. Multivariate analysis showed that in-hospital mortality was higher in the low iCrs group than in the normal iCrs group (adjusted odds ratio, 6.04 [1.13, 32.26]; p = 0.04).ConclusionLow iCrs was associated with an increased risk of requiring postoperative mechanical ventilation. An additional result of poor survival related to low iCrs may require further study.

Project description:Proteins are the active players in performing essential molecular activities throughout biology, and their dynamics has been broadly demonstrated to relate to their mechanisms. The intrinsic fluctuations have often been used to represent their dynamics and then compared to the experimental B-factors. However, proteins do not move in a vacuum and their motions are modulated by solvent that can impose forces on the structure. In this paper, we introduce a new structural concept, which has been called the structural compliance, for the evaluation of the global and local deformability of the protein structure in response to intramolecular and solvent forces. Based on the application of pairwise pulling forces to a protein elastic network, this structural quantity has been computed and sometimes is even found to yield an improved correlation with the experimental B-factors, meaning that it may serve as a better metric for protein flexibility. The inverse of structural compliance, namely the structural stiffness, has also been defined, which shows a clear anticorrelation with the experimental data. Although the present applications are made to proteins, this approach can also be applied to other biomolecular structures such as RNA. This present study considers only elastic network models, but the approach could be applied further to conventional atomic molecular dynamics. Compliance is found to have a slightly better agreement with the experimental B-factors, perhaps reflecting its bias toward the effects of local perturbations, in contrast to mean square fluctuations. The code for calculating protein compliance and stiffness is freely accessible at https://jerniganlab.github.io/Software/PACKMAN/Tutorials/compliance.

Project description:IntroductionWe performed a meta-analysis of the current literature to assess the association of caudal block and postoperative complication rates following hypospadias repair.MethodsA Systematic literature search was conducted on October 2017. Five reviewers independently screened, identified, and evaluated comparative studies assessing postoperative outcomes following hypospadias repair with and without caudal block. The incidence of post-surgical complications from each study was extracted for caudal block and control groups to generate the odds ratio (OR) and corresponding 95% confidence intervals (CI). Effect estimates were pooled using inverse-variance method with random-effects model. Subgroup analyses were performed according to study type and hypospadias severity.ResultsNine studies (2096patients) of low- to moderate-quality were included for meta-analysis. Overall pooled effect estimates demonstrated increased occurrence of postoperative complication rates among patients with caudal block (OR 2.32; 95% CI 1.29-4.16). Subgroup analysis according to hypospadias severity revealed that a significant increased OR in complication rate was noted among proximal hypospadias (OR 3.55; 95% CI 1.80-7.01), but not distal hypospadias (OR 1.31; 95% CI 0.59-2.88).ConclusionsOur meta-analysis of poor-quality evidence may have revealed a significant association between caudal block and postoperative complications following hypospadias repair. However, subgroup analysis demonstrated that hypospadias severity is important in determining complication rates, suggesting that confounding factors and selection bias may play a central role in characterizing the true effect of the anesthesia approach.

Project description:ObjectiveBone marrow aspiration and lumbar puncture are procedures frequently performed in pediatric oncology. We aimed at assessing the incidence and risk factors of perioperative complications in children undergoing these procedures under sedation or general anesthesia.MethodsBased on the APRICOT study, we performed a secondary analysis, including 893 children undergoing bone marrow aspiration and lumbar puncture. The primary outcome was the incidence of perioperative complications. Secondary outcomes were their risk factors.ResultsWe analyzed data of 893 children who underwent 915 procedures. The incidence of severe adverse events was 1.7% and of respiratory complications was 1.1%. Prematurity (RR 4.976; 95% CI 1.097-22.568; P = 0.038), intubation (RR: 6.80, 95% CI 1.66-27.7; P =0.008), and emergency situations (RR 3.99; 95% CI 1.14-13.96; P = 0.030) increased the risk for respiratory complications. The incidence of cardiovascular instability was 0.4%, with premedication as risk factor (RR 6.678; 95% CI 1.325-33.644; P =0.021).ConclusionA low incidence of perioperative adverse events was observed in children undergoing bone marrow aspiration or lumbar puncture under sedation and/or general anesthesia, with respiratory complications being the most frequent. Careful preoperative assessment should be undertaken to identify risk factors associated with an increased risk, allowing for appropriate adjustment of anesthesia management.

Project description:BackgroundTibial tubercle osteotomy (TTO) is a well-established surgical treatment option for patients with patellofemoral disorders.PurposeTo determine the rate of early (≤90 day) postoperative complications after TTO and variables related to postoperative complications.Study designCase series; Level of evidence, 4.MethodsPatients who underwent TTO at a single academic institution within a 15-year period (2008-2022) were identified. All patients with a minimum 90-day follow-up were considered for study inclusion. Exclusion criteria were age younger than 14 years and revision surgery. Patient characteristics, surgical history, and concomitant procedures were identified, and risk factor analysis was performed to identify variables associated with early postoperative complications.ResultsA total of 344 knees in 313 patients met eligibility criteria and were included in the final analysis. One intraoperative complication (0.3%), a premature closure of the incision before repair of the vastus medialis, was identified. There were 141 postoperative complications (138 surgical, 3 medical) in 118 patients for a complication rate of 34.3%. The most common complications were stiffness requiring a nonstandard-of-care intervention (16.3%), superficial wound infection/wound dehiscence (8.1%), and hemarthrosis/effusion requiring aspiration (5.8%). Patients experiencing postoperative complications were older (mean difference, 3.49 years; 95% CI, 1.26-5.73 years; P = .002), had a higher mean Charlson Comorbidity Index (mean difference, 0.26; 95% CI, 0.08-0.45; P = .006), and were more likely to be current smokers (P = .015) compared with patients with no complications. Inpatient surgery (defined as surgery in a hospital setting with at least 1 overnight stay) was associated with postoperative complications (odds ratio [OR], 2.29; 95% CI, 1.39-3.77; P = .001); this association remained significant generation of a multivariate model (OR, 2.07; 95% CI, 1.19-3.58; P = .010). Previous surgery on the ipsilateral knee (P < .001) and concomitant autologous chondrocyte implantation (P = .046) were also associated with postoperative complications.ConclusionThe study findings indicated a low intraoperative complication rate (0.3%) and a relatively high early postoperative (≤90 day) complication rate (34.3%) after TTO. Variables associated with postoperative complications included greater age, higher Charlson Comorbidity Index, surgery in an inpatient setting, previous surgery on the ipsilateral knee, and concomitant autologous chondrocyte implantation.

Project description:BackgroundSince postoperative pulmonary complications are one of the main causes of morbidity and mortality in patients undergoing lung resection surgery, we performed a meta-analysis to compare the incidence of postoperative pulmonary complications and hospital death, and the length of hospital stay in patients who received nonintubated or intubated anesthesia during thoracoscopic surgery for lung resection and further explore the tricks in nonintubated anesthesia.MethodsPubMed, Embase, and Cochrane Library were searched from inception to September 2017. We included eligible research comparing nonintubated anesthesia with intubated anesthesia in thoracoscopic surgery for lung resection. The primary outcomes involved postoperative pulmonary complications, hospital death, and hospital stay. The rates and causes of conversion from nonintubated anesthesia to intubated anesthesia were also analyzed.ResultsAfter screening through 754 potentially relevant articles, we included 3 randomized controlled trials and 7 observational studies with 1138 patients. There was no perioperative mortality in 2 groups. The nonintubated group revealed comparable postoperative pulmonary complications (OR?=?0.57; P?=?.07; P for heterogeneity?=?.49, I?=?0%) and shorter hospital stay (WMD?=?-1.10; P?<?.00001; P for heterogeneity?=?.84, I?=?0%) in overall findings with little heterogeneity.ConclusionNonintubated anesthesia in thoracoscopic surgery for lung resection shortened the length of hospital stay compared with intubated anesthesia. However, the incidence of postoperative pulmonary complications was comparable between nonintubated and intubated group. Given the potential perioperative emergencies, such as persistent hypoxemia, carbon dioxide retention, or extensive pleural adhesions, nonintubated anesthesia in lung resection surgery requires extra vigilance to ensure the safety of the patients and the success of the surgery. Powerful randomized controlled trials in the future are essential to provide more certainty and address long-term effectiveness. Only when anesthesiologists and surgeons make efforts together can better clinical outcomes in lung resection surgery be achieved.

Project description:ObjectivesPostoperative pulmonary complications (PPCs) provoke an extended hospital stay and increased postoperative mortality. Although several factors can cause PPCs, smoking is the only factor that can be adjusted within a short period of time preoperatively. However, the optimal period of smoking cessation to reduce the risk of PPCs remains unclear.MethodsA total of 1260 patients with primary lung cancer who underwent radical pulmonary resection between January 2010 and December 2021 were analysed retrospectively.ResultsWe classified patients into 2 groups: non-smokers (patients who had never smoked) and smokers (patients who had ever smoked). The frequency of PPCs was 3.3% in non-smokers and 9.7% in smokers. PPCs were significantly less frequent in non-smokers than in smokers (P < 0.001). When smokers were classified according to the duration of smoking cessation, the frequency of PPCs was significantly lower for a duration of 6 weeks or more than for <6 weeks (P < 0.001). In a propensity score analysis performed for 6 or >6 and <6 weeks' smoking cessation in smokers, the frequency of PPCs was significantly lower for smokers with 6 or more weeks' smoking cessation than for smokers with <6 weeks' smoking cessation (P = 0.002). A multivariable analysis identified <6 weeks' smoking cessation as a significant predictor of PPCs for smokers (odds ratio: 4.55, P < 0.001).ConclusionsSmoking cessation for 6 or more weeks preoperatively significantly reduced the frequency of PPCs.

Project description:Background: Patients undergoing carotid endarterectomy (CEA) for severe carotid stenosis are vulnerable to postoperative delirium, a complication frequently associated with poor outcome. This study investigated the impact of processed electroencephalogram (EEG)-guided anesthesia management on the incidence of postoperative delirium in patients undergoing CEA. Methods: This single-center, prospective, randomized clinical trial on 255 patients receiving CEA under general anesthesia compared the outcomes of patient state index (PSI) monitoring [SEDLine Brain Function Monitor (Masimo, Inc, Irvine, CA)] (standard group, n = 128) with PSI combined with density spectral array(DSA) -guided monitoring (intervention group, n = 127) to reduce the risk of intraoperative EEG burst suppression. All patients were monitored by continuous transcranial Doppler ultrasound (TCD) and near-infrared spectroscopy (NIRS) to avoid perioperative cerebral hypoperfusion or hyperperfusion. According to the surgical process, EEG suppression time was calculated separately for three stages: S1 (from anesthesia induction to carotid artery clamping), S2 (from clamping to declamping), and S3 (from declamping to the end of surgery). The primary outcome was incidence of postoperative delirium according to the Confusion Assessment Method algorithm during the first 3 days post-surgery, and secondary outcomes were other neurologic complications and length of hospital stay. Results: There were no episodes of cerebral hypoperfusion or hyperperfusion according to TCD and NIRS monitoring in either group during surgery. The incidence of postoperative delirium within 3 days post-surgery was significantly lower in the intervention group than the standard group (7.87 vs. 28.91%, P < 0.01). In the intervention group, the total EEG suppression time and the EEG suppression time during S2 and S3 were shorter (Total, 0 "0" vs. 0 "1.17" min, P = 0.04; S2, 0 "0" vs. 0 "0.1" min, P < 0.01; S3, 0 "0" vs. 0 "0" min, P = 0.02). There were no group differences in incidence of neurologic complications and length of postoperative hospital stay. Conclusion: Processed electroencephalogram-guided general anesthesia management, consisting of PSI combined with DSA monitoring, can significantly reduce the risk of postoperative delirium in patients undergoing CEA. Patients, especially those exhibiting hemodynamic fluctuations or receiving surgical procedures that disrupt cerebral perfusion, may benefit from the monitoring of multiple EEG parameters during surgery.
