Posterior quadratus lumborum versus transversus abdominis plane block for inguinal hernia repair: a prospective randomized controlled study.

Background And Objectives: We aimed to compare the analgesic effects of both posterior (type 2) Quadratus Lumborum Block (QLB) and Transversus Abdominis Plane Block (TAPB) compared to spinal anesthesia alone for postoperative pain management in inguinal hernia repair.

Methods: This study enrolled 63 patients scheduled for open inguinal hernia repair. The eligibility criteria were undergoing elective unilateral inguinal hernia repair surgery, having an American Society of Anesthesiologists (ASA) physical status I, II, or III, and not suffering from any chronic pain condition.

Unexpectedly prolonged fasting and its consequences on elderly patients undergoing spinal anesthetics. A prospective observational study1.

Purpose: To measure the preoperative fasting durations with respect to time of the day and its effect on vital parameters and electrocardiogram in elderly patients undergoing surgery under spinal anesthesia.

Methods: This study investigated 211 patients older than 60 years undergoing elective surgery under spinal anesthesia. Patients scheduled for surgery in morning hours (AM) and afternoon hours (PM) were compared.
