Effect of preoperative liposomal bupivacaine single-injection pericapsular nerve group (PENG) block on lower extremity deep vein thrombosis in elderly patients with hip fractures: a randomised controlled, double-blind, prospective clinical study protocol.

ABSTRACT:

Introduction

Deep vein thrombosis (DVT) of the lower limbs has a significantly higher incidence among elderly populations than that observed in other types of fractures, prolonged immobilisation and the systemic inflammatory response triggered by preoperative pain are the main risk factors. Liposomal bupivacaine (LB) single-injection pericapsular nerve group (PENG) block has demonstrated effective analgesia both before and after surgery, while preserving motor function in patients with hip fracture. Although regional nerve block is a well-established component of preoperative multimodal analgesia, its potential role and underlying mechanisms in the prevention of DVT in elderly patients with hip fracture remain largely unexplored.
