Active clinical trials for "Postoperative Complications"

The purpose of this study is to assess the association between the "point-of-care" (POC) measured ChE activity (Acetylcholinesterase (ChE) + Buturylcholinesterase (ChE)) and postoperative delirium in elderly patients undergoing cardiac surgery. Furthermore the investigators aim to identify factors, which influence the baseline levels and the time course of ChE activity.

Background: The list of studies with inconsistent data regarding the effect of intra-operative ventilatory management on post-operative lung injury is large. The literature is lacking data on the least injurious way of ventilating surgical patients intra-operatively. This study is necessary to support future guidelines on the practice of intra-operative mechanical ventilation. Specific Aim: The aims of this study is first to describe intra-operative ventilatory practices at the American University of Beirut Medical Center (AUBMC), (with particular focus on the mode of ventilation, tidal volume per body weight and PEEP settings) and second, to identify the post-operative complications that could be associated with particular settings. Methodology: This is a prospective observational study that will be conducted in the operating room at AUBMC, on patients being admitted for surgeries under general anesthesia. During the patient's stay in the hospital, targeted process (patient characteristics, surgical procedure, mechanical ventilation management, anesthesiologist characteristics) and outcomes parameters (postoperative pulmonary complications) will be collected for analysis. Patients will be monitored and followed up with intraoperatively and postoperatively. Analysis: Different parameters and outcomes will be collected and by subgrouping the patients per their medical history statistical significance will be tested to reach a correlative analysis to the outcomes documented. Statistical comparison will be made using the ANOVA, Student's t-test, and Chi-squared test. Level of statistical significance will be considered at p<0.05. Mean age, weight, height and BMI of participants in the different groups will be calculated. ANOVA test will be performed to test statistical significance to compare the different means between different subgroups. A two sided P value of less than 0.05 was considered to be significant Significance: The literature is lacking data on the least injurious way of ventilating surgical patients intra-operatively. This study is necessary to support future guidelines on the practice of intra-operative mechanical ventilation

A randomized controlled trial to determine whether changing of gloves by the surgical team during cesarean section may decrease post-operative infectious morbidity and wound complications

The POSE study will predict critical stages and outcome in a large sample of all surgical and non-surgical interventional patients ≥80 years of age in Europe.

The purpose of the study is to measure patient- temperature in the perioperative period of patients undergoing plastic surgery in an ambulatory surgical unit. This study will evaluate if active warming with self-warming blanket (Easywarm®) is as effective as active warming with forced-air blanket (BairHugger®). Second the study will evaluate if one or both methods is effective in preventing perioperative hypothermia.

Hypothermia is a frequent perioperative complication. Its appearance can have deleterious effects such as perioperative bleeding or surgical site infection. Once the temperature has decreased, its treatment is difficult. Preoperative warming prevents hypothermia, lowering the temperature gradient between core and peripheral compartments and reducing thermal redistribution. The most recent clinical practice guidelines advocate for active prewarming before induction of general anaesthesia since it is very effective in preventing perioperative hypothermia. However, the ideal warming time prior to the induction of anesthesia has long been investigated. This study aims to evaluate if different time periods of preoperative forced-air warming reduces the incidence of hypothermia at the end of surgery in patients submitted to laparoscopic urological surgery under general anesthesia. This is an observational prospective study comparing routine practice of pre-warming in consecutive surgical patients scheduled to laparoscopic prostatectomy or nephrectomy between August and December 2018. In this study 64 - 96 patients will be included and prewarming will be applied following routine clinical practice. The prewarming time will depend on the time the patient has to wait before entering in the operating theatre. Measurement of temperature will be performed using an esophagic thermometer. Patients will be followed throughout their hospital admission. Data will be recorded using a validated instrument and will be analysed using the statistics program R Core Team.

This is a randomized clinical trial, double-blind, placebo-controlled study with the goal to assess the influence of using N-AcetylCysteyn (NAC) for prevention of AKI (Acute Kidney Injury) in post operatory of valve replacement until their discharge or death

There are few data of paediatric peri-operative morbidity and mortality in South Africa. There is little information on the burden or profile of surgical disease in the paediatric population, the level of anaesthesia or surgical care (specialist versus non-specialist) for paediatric patients, the quality of peri-operative care or contributing factors to poor outcomes. In order to understand current paediatric peri-operative morbidity and mortality in South Africa, it is important to start obtaining these data. Risk factors can be identified and changes can be in implemented accordingly to improve future outcomes. The study will take place over fourteen-days. It is a South African national multi-centre prospective cohort study of paediatric patients (<16 years) undergoing surgery. The SAPSOS study (as was the South African Surgical Outcomes Study (SASOS) study) will be based on the methodology of the European Surgical Outcomes Study (EuSOS). This study has important public health implications for South Africa as surgery is now recognized internationally as an essential part of public health, yet still needs to be defined as a priority in South Africa. Policy-makers and healthcare providers need evidence to plan resource allocation in a way that will improve quality and outcomes. The data from SAPSOS and SASOS, would provide a platform for government and health care providers in South Africa to appropriately allocate funding, make policy decisions and plan future peri-operative healthcare in South Africa.

Whether the pre-operative blood lipid level and post-operative cardiovascular events is associated is unknown. This study is to find out the main blood lipid and relative protein level change and the post-operative cardiovascular events occurrence.

Frailty is prevalent in older adults and may be a better predictor of post-operative morbidity and mortality than chronological age. Preoperative risk factors and physiological reserves were assessed on patients more than 70 years old who are scheduled for surgery under general or regional anesthesia. The aim of this retrospective analysis was to examine the impact of relevant geriatric assessments on adverse outcomes in older surgical patients.
