NCT06753409
This study aims to evaluate whether the reduction in the amount of intraoperative norepinephrine required to prevent hypotension, facilitated by processed electroencephalography (pEEG) -guided general anesthesia, will lead to a decrease in postoperative complications, particularly acute kidney injury (AKI).
NCT06598228
Acute kidney injury (AKI) is a common complication after pediatric liver transplantation (PLT), and renal impairment after LT has proven to be related with increased graft failure and mortality. The recovery mode of kidney injury after PLT has not been systematically studied. Therefore, in this study the investigators aimed to systematically evaluate prognosis of AKI after PLT, combine the recovery mode of AKI with related risk factors, and establish a relationship between AKI and CKD.

The authors aimed to determine the risk factors associated with postoperative acute kidney injury in patients undergoing total joint arthroplasty.
NCT05569265
MAIN AIM OF THE STUDY To establish whether hemodynamic management guided by the hypotension prediction index (HPI) guided by the administration of intravenous fluids and vasoactive drugs in patients undergoing elective major abdominal surgery reduces the incidence of postoperative moderate-severe acute kidney injury (AKI) in the 30 days after surgery. STUDY DESIGN A low intervention level clinical, blinded, controlled, randomized, multicenter, with daily follow-up of patients until hospital discharge and of postoperative complications and mortality 30 days after surgery will be performed. This is a low-intervention clinical trial comparing standard treatments: * The drugs used in the investigation are licensed. * The drugs are used according to the indications contemplated in the technical data sheet and there are published scientific data on their efficacy and safety. * The complementary diagnostic or follow-up procedures entail a very limited additional risk or burden to the safety of the subjects, which is minimal compared to that of standard clinical practice. STUDY DISEASE Intraoperative hemodynamic monitoring and management in surgical patients undergoing major abdominal surgery. STUDY POPULATION AND TOTAL NUMBER OF PATIENTS The sample of this study consists of patients of both genders, aged over 65 years and/or physical status ASA III or IV, undergoing elective major abdominal surgery (abdominal, urological, gynecological) under general/combined anesthesia (using laparoscopic or open approaches. To detect a 5% absolute reduction (from 10% to 5%) in the primary outcome variable (postoperative AKI up to 30 days) with a sample size ratio of 1%, and an overall type I error rate of 5%, we need 870 patients (435 per arm). Assuming a 10% loss rate, the total amounts to 958 patients, 479 for each group. DURATION OF THE STUDY The total planned duration of the overall study, which includes authorization, recruitment of subjects, and follow-up of subjects until completion of the analysis of the results obtained, is 19 months.
NCT05090254
Perioperative cardiac output-guided goal-directed therapy (GDT) triggers fluid, vasopressor, and inotrope administration assuming that optimizing cardiac output (i.e., global blood flow) ensures adequate oxygen delivery and microcirculatory perfusion - that are usually not directly monitored during goal-directed therapy. There is increasing evidence that perioperative cardiac output-guided goal-directed therapy may reduce postoperative complications compared to routine hemodynamic management in high-risk patients having major surgery. The effect of cardiac output-guided goal-directed therapy algorithms on perioperative oxygen delivery and consumption as well as microcirculatory perfusion, however, is unknown. The investigators aim to investigate the effect of using different cardiac output-guided goal-directed therapy algorithms on perioperative oxygen delivery and consumption as well as sublingual microcirculatory perfusion compared to routine perioperative hemodynamic management in patients having major abdominal surgery with general anesthesia.
NCT04922866
Acute kidney injury (AKI) is a severe complication after liver resection and is associated with morbidity and mortality. The incidence of postoperative AKI is significantly higher in elderly patients, especially in those with comorbidities. There is currently limited evidence on the incidence and associations of postoperative AKI in elderly patients following liver resection. This study will evaluate the incidence and associations of AKI in elderly patients after liver resection and its impact on postoperative mortality.
