Hemodynamic Effects of Lithotomy Position in Surgical Patients (PH-LITHO)

Anesthesia-induced hypotension is a common occurrence in elderly hypertensive patients and is closely associated with increased postoperative morbidity * This study aims to investigate whether the lithotomy position, a non-pharmacological and cost-free approach, can reduce the incidence of post-induction hypotension (PIH) in this high-risk population by increasing venous return Sixty patients aged 65-80 with a history of hypertension were randomly assigned to either the Supine Group (Group S) or the Lithotomy Group (Group L) * In Group L, patients were placed in the lithotomy position 120 seconds before the start of anesthesia induction * Blood pressure was monitored every minute for the first five minutes following induction * The study evaluates whether this simple positioning strategy can maintain hemodynamic stability, reduce the drop in mean arterial pressure, and decrease the overall need for vasopressor medications like ephedrine
