The Impact of Driving Pressure-Guided Positive End-Expiratory Pressure Ventilation on Cerebral Blood Flow and Pulmonary Function in Patients Undergoing Laparoscopic Radical Prostatectomy.

Purpose: To examine the impact of driving pressure-guided positive end-expiratory pressure ventilation on cerebral blood flow and pulmonary function in patients undergoing laparoscopic radical prostatectomy.

Methods: A retrospective analysis was conducted on clinical data from patients who underwent laparoscopic radical prostatectomy at our hospital between June 2022 and June 2023. The patients were divided into two groups, namely the conventional ventilation group and the driving pressure-guided positive end-expiratory pressure ventilation group.

Intraoperative venous congestion rather than hypotension is associated with acute adverse kidney events after cardiac surgery: a retrospective cohort study.

Background: The pathophysiological mechanisms by which venous congestion and hypotension lead to acute adverse kidney events after cardiac surgery with cardiopulmonary bypass have not been elucidated. We tested the hypothesis that intraoperative hypotension and venous congestion are associated with acute kidney injury and acute kidney disease.

Methods: Primary exposures were venous congestion and intraoperative hypotension defined by central venous pressure ≥12, 16, or 20 mm Hg or mean arterial pressure ≤55, 65, or 75 mm Hg.

Dexmedetomidine effect on delirium in elderly patients undergoing general anesthesia: A protocol for systematic review and meta-analysis.

Background: Delirium is a common postoperative complication. Many studies have found that dexmedetomidine is associated with a reduced incidence of postoperative delirium (POD). This meta-analysis aimed to analyze the effects of dexmedetomidine on POD incidence among elderly patients undergoing general anesthesia.
