Active clinical trials for "Postoperative Complications"

This retrospective, population-based cohort study will evaluate the comparative effectiveness of peripheral nerve blocks on patient outcomes after ambulatory shoulder surgery in adults patients undergoing surgery in Ontario.

Whereas there are several validated systems for reporting postoperative complications, there are only a few and not prospectively validated systems for reporting intraoperative complications. The investigators developed a definition and CLASSification for Intraoperative Complications CLASSIC within a Delphi study involving international interdisciplinary experts. As both surgery and anaesthesia may be involved in complications in the perioperative period, all patient-related intraoperative complications occurring between skin incision and closure are considered in this reporting system. CLASSIC was updated to ClassIntra® v1·0, by encompassing five severity grades to align with the validated Clavien-Dindo Classification for grading postoperative complications. The aim of this international multicentre observational cohort study is to assess the validity and practicability of this newly derived and updated classification system ClassIntra® in patient undergoing an in-hospital surgical procedure. Providing an easy applicable and internationally validated classification system is a contribution to improve quality of health care and patient safety.

Pancreatectomy represents the classic approach for resectable lesions of the pancreas, duodenum and periampullary region. Due to the technical skills required, the complex anatomy and the extreme fragility of the pancreatic parenchyma, pancreatic resection is still considered to be at risk of postoperative complication mainly due to pancreatic juice leaks. Anastomotic leaks are the major cause of morbidity and in-hospital mortality due to the activation of pancreatic enzymes and the following infectious and hemorrhagic complications. Severe complications negatively affect postoperative outcomes, long-term survival, quality of life, and costs. Operative mortality traditionally has been defined as the rate within 30 days or during the initial hospitalization. But in pancreatic surgery mortality rates within 90 days after pancreatic resection are double those at 30 days. In the present study, the investigators sought to evaluate the usefulness of postoperative CT-scan on the seventh postoperative day before discharging the patients to detect undiagnosed postoperative complication.

Cigarette smoking is associated with surgical complications, including wound healing and surgical site infection. However, the association between smoking status and postoperative wound complications is not completely understood. Our objective is to investigate the effect of smoking on postoperative wound complications for major surgeries.

The investigators decided to assess the prognostic value of NLRP3 inflammasome level in early after heart valve replacement surgery and whether it was related to postoperative cognitive dysfunction. Study population included 90 subjects. Neuropsychological tests were administrated one day before surgery and seven days after surgery. Before induction of anesthesia, before the end of the operation, 7 days after the operation, peripheral venous blood was sampled to measure IL-1B, IL-18 and NLRP3 inflammatory protein expression in peripheral blood monocytes. Analyze the data and draw conclusions.

Studying the effects of both inhalational anesthetics desflurane and sevoflurane on hepatic integrity and renal function, guided by recent blood and urine biomarkers in patients undergoing laparoscopic cholecystectomy surgery.

It has been estimated that in the United States alone 48 million operations are performed annually and most involve the use of multiple surgical items, including needles and other sharp objects, surgical sponges, and surgical instruments1. Textile material and instruments forgotten in a patient undergoing an invasive procedure is a negligence of an entire team responsible for maintaining patient safety. A retained surgical foreign body (RSFB) usually requires at least a second surgery for retrieval of the object, and also carries a risk for major complications including morbidity and death2. Retained foreign bodies are underreported to minimize exposure to possible litigation3. Therefore, the real occurrence of RSFB is underestimated, recently there has reported an incidence of 0.356 / 1,000 patients whereas others reported a rate of 1/5000 with an associated mortality ranging from 11 to 35% 4-5. Therefore, there is a need for improved systems and methods for identifying and tracking surgical items, including needles and other sharp objects, surgical sponges, and surgical instruments during a surgical procedure.

Serum lactate is a risk factor for postoperative complications in patients undergoing cytoreduction surgery in peritoneal carcinomatosis

Post-operative monitoring of all patients after anaesthesia in the post anaesthesia care unit (PACU) is standard of care today. It helps to reduce morbidity and even mortality in high-risk patients. In addition to clinical monitoring by qualified staff, standard monitoring in the PACU includes non-invasive, intermittent, haemodynamic monitoring. This research is going to investigate the influence of the continuation of goal directed haemodynamic optimization in the recovery room on the basis of non-invasive monitoring tools, i.e. ultrasound and the volume-clamp method, in regard of length of stay in the PACU and postoperative complications.

The purpose of this study is to objectively quantify liver fat content (LFC) by Magnetic Resonant Imaging (MRI) prior to major liver surgery, and to investigate its association with post-operative complications.
