Complication of Anesthesia

Observational retrospective study of patients in need of acute surgical care admitted to Skåne University Hospital between 2009 and 2019.

This prospective, randomized controlled trial aims to compare two multimodal regional anesthesia strategies for postoperative analgesia in elective total hip arthroplasty (THA) performed via anterior approach. Patients will be randomized to receive either a Pericapsular Nerve Group (PENG) block combined with a Lateral Femoral Cutaneous Nerve (LFCN) block, or a PENG block combined with wound infiltration (WI). The primary outcome is postoperative pain intensity at rest, measured by Numerical Rating Scale (NRS) at 6 hours after surgery. Secondary outcomes include dynamic pain scores at 6, 24, and 48 hours, total opioid consumption, time to first rescue analgesia, quadriceps strength, hip flexion angle, length of stay, and adverse events. All procedures are routinely used in clinical practice and carry minimal additional risk. Safety will be continuously monitored by the Principal Investigator and the study team according to an internal Safety Monitoring Plan.
