Active clinical trials for "Postoperative Complications"

This study evaluates postoperative morbidity of patients that undergo free gingival graft harvesting from palate with or without use of autogenous PRF (Platelet Rich Fibrin) membranes to cover the donor site.In the Test Group venous blood sampling was done in order to prepare PRF membranes used to cover the donor site, whereas in Control Group hemostatic agents with oxidized and regenerated cellulosa were used.

This is an interventional trial to introduce two short animated videos into preoperative counseling/consent and to compare patient comprehension and satisfaction with a multimedia approach compared to standard of care currently. The investigators anticipate that patients will retain more information about their surgery and peri-operative care and will be more satisfied with a multimedia approach.

In an estimated 150,000 patients, a knee joint replacement is performed in Germany every year. The perioperative care of the patients aims at an optimal surgical technique, which leads to a high functionality in the joint, and above all at an adequate pain treatment. Patients experience pain especially intraoperatively and in the first days after the operation. The intensity of pain is a decisive factor that can hinder the patient's mobilization. In the KneeOptOut study (ethics application number EA4/009/17), which has already been successfully carried out and approved by this ethics committee, it was shown that the use of local infiltration anaesthesia (LIA) for pain therapy after primary knee endoprosthetics is comparable to catheter-supported regional anaesthesia (manuscript under review at the European Journal of Anaesthesiology). During surgery, the morphine requirement of patients in the LIA group was significantly higher than that of patients who underwent catheterization. Postoperatively, however, both subjective pain by VAS and opiate consumption were comparable. In order to optimize the intraoperative opiate need/consumption, an early-intraoperative procedure for local infiltration anesthesia will now be compared with the previous late-intraoperative procedure. Both procedures correspond to SOP for the treatment of primary knee endoprostheses and are currently used depending on the surgeon's requirements.

The purpose of this study is to evaluate the feasibility of a closed-loop (automated) fluid administration system to deliver fluids using feedback from standard operating room hemodynamic monitors. In standard anesthesia care the rate of IV fluid administration to the patient is determined by the anesthesiologist caring for the patient. In this study protocol, the rate of fluid administration will be determined instead by the closed-loop (automated) control system under the supervision of the anesthesiologist. The system will independently decide when to give fluid and at what rate; the supervising anesthesiologist will monitor the system to ensure appropriate volumes are being delivered and to intervene if necessary.

The purpose of this multi-center randomized trial is to identify any differences in the complication rates of patients undergoing Hartmann's (end colostomy) versus Primary Anastomosis (with defunctioning ileostomy) for left-sided colonic performation (including the stoma reversal operation).

The aim of this study is to demonstrate the influence of peri-operative nutrition on the preservation of lean body mass after gastric bypass, as well as it's influence on postoperative complications.

The aim of this project is to develop a machine-learning model for calculating the risk of postoperative complications. In addition to the data collected during the premedication, the model will include all intraoperative values recorded in the Patient Data Management System (PDMS), which include not only vital and respiratory parameters, but also medication and doses, intraoperative events and times. Postoperative complications are defined according to their severity according to the Clavien-Dindo score (Dindo, Demartines et al., 2004) and are collected from the data available in the health information system (HIS). The machine-learning model is created using an extreme-gradient boosting algorithm which has been updated with new data from the year 2021 to ensure accuracy of the model.

Currently, there is a controversy regarding the best approach for simultaneous repair of bilateral inguinal hernia. The aim of this study was to compare the outcome of laparoscopic versus open repair of bilateral inguinal hernia

This study compared differences in weight loss, comorbidity resolution and complications and reoperations between a recently established sleeve gastrectomy (SG) and prior laparoscopic Rox-en-Y gastric bypass (RYGB).

The study aimed to evaluation of Tubularized incised palate urethroplasty with spongioplasty-dartosoraphy reinforcement (group A) through comparing of functional and cosmetic results of this technique with the conventional TIP urethroplasty (group B).
