Active clinical trials for "Intraoperative Complications"

Study Protocol: Outcome Measurements Primary Outcome The main outcome will be the preoperative performance of the dIVCmax/IVCCI ratio to foresee the incidence of hypotension after spinal anesthesia in a greater extent to that of the established IVCCI measurements. Secondary Outcomes To identify other echocardiographic or clinical measurements that can predict an intraoperative spinal-induced haemodynamic instability. Sample Size Calculation A pilot study of 20 patients revealed a detected area under the ROC curve (AUC) of 0,91 for dIVCmax/IVCCI and for dIVCmax 0,82 with rank correlation between the two assays being 0.87 in both positive and negative cases. Based on this result, a sample of 56 patients will achieve 80% power to detect significant difference (at a level 0.05) between dIVCmax/IVCCI and dIVCmax. Potential Benefits of the Study The results of this study will allow us to determine which clinical or US-measurement can yield better performance so as a preoperative prediction of spinal-induced hypotension can be achieved; that way these measurements can permit and guide a targeted preoperative fluid challenges prior to the implementation of spinal anesthesia Potential Side Effects of the Study Participation in this protocol will not put patients at higher risk for complications since we do not perform any intervention (either pharmacological or surgical) There will be no occupational risks to researchers or assistants. Proposed Timetable According to the exclusion criteria and taking into account the number of cases performed in our department per monthly basis, it should take us approximately 6 months to recruit 60 patients.

Background: Three-dimensional (3D) printing has been increasingly used in medical applications with the creation of accurate patient-specific 3D printed models in medical imaging data. However, research on 3D printing in pancreaticobiliary disease is limited with lack of studies on validation of model accuracy. Methods: This is a where general surgery residents, are introduced to 5 distinct hepatopancreatobiliary disease scenarios to generate a perception and required to compare their perception level of these cases with computed tomography (CT), 3D images and 1:1 solid models that the pathology, diverse diagnosis and presurgery diagnosis stages can be investigated.

Acute inflammation induced by surgery and sepsis is complicated by the development of iron-restricted anemia due to the up-regulation of hepcidin. Excess hepcidin causes intracellular sequestration of iron, decreasing its availability for erythropoiesis. Hepcidin might be a potential target to reduce transfusion requirements in surgical and sepsis patients. Vitamin D supplementation might constitute a novel strategy to modulate the hepcidin-ferroportin-iron axis. Up to now, there are no data regarding the possibility that by using vitamin D supplementation in surgical and septic shock patients, the physicians could ameliorate anemia and, hence, reduce transfusion requirements. Aim: to conduct a randomised controlled trial to determine the impact of high-dose vitamin D enteral supplementation on serum hepcidin levels and transfusion requirements after major abdominal surgery and in septic shock patients.

Aspirin is very common in older patients. Therefore many of the investigators patients have aspirin. The aim of the study is to proof that Transurethral Surgery of the bladder or the prostate can be performed with aspirin.

Primarily, the investigators want to test the hypothesis that it is possible to detect epileptiform EEG during cardiac surgery under general anesthesia. Furthermore, the investigators will examine if those epileptic potentials coincide, follow or are unrelated to ischemic events detected by EEG or Near-infrared spectroscopy (NIRS). Finally, the investigators will look for independent associations between intraoperative seizures (with or without ischemic events) and postoperative neurological outcome, as well as between intraoperative seizures (with or without ischemic events) and the total amount of TXA given.

This clinical observational study investigates perioperative oxygen consumption and delivery in elderly patients undergoing major surgery. The primary objectives are to characterise the perioperative oxygen delivery, consumption and potential markers of oxygen debt. Secondary objective is to estimate the correlation between oxygen delivery/consumption and postoperative outcomes to guide the design of a future trial.

Acute myocardial infarction (MI) is a significant complication following non-cardiac surgery. We sought to evaluate incidence of perioperative MI, its preoperative - and intraoperative - risk factors and outcomes after this complication.

Protective ventilation decreased morbidity and mortality in adults' patients and is now a standard of care in intensive care unit and in anesthesiology. In children, there is no evidence in the literature to recommend protective ventilation during anaesthesia. Moreover the ratio of instrumental dead space to tidal volume is higher in children than in adults. Therefore, it is difficult to propose an "optimal" tidal volume for all children. The objective of this study is to evaluate the use of alveolar ventilation (estimated by the volumetric capnography) in children under anesthesia. The hypothesis is that in children, alveolar ventilation reported to ideal body weight is a constant to maintain normocarbia, unlike the tidal volume.

The purpose of this study is to assess patient satisfaction with the Titan one touch release penis prosthesis and to register complications with this prosthesis. This will regard the first prostheses inserted at Herlev Hospital/Frederikssund Hospital. Patient satisfaction will be assessed by mailing out the "Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) Questionnaire" and recording the patient answers. The most important question will be "Overall how satisfied are you with penile prosthesis?". Complications (including infection, bleeding, and mechanical failure) will be assessed by a patient chart review and confirmed by a brief phone interview.

Ventilation management in paediatric anaesthesia remains difficult because of the wide range of age and weight, and therefore practices are heterogeneous. In adults, protective ventilation during anesthesia is now a standard of care but in children there is no level of evidence to recommend it. The aim of the study was to describe current practice and the factors associated with the use of high tidal volume during anaesthesia in children in France.
