PENG Block: Continuous Infusion vs. Programmed Intermittent Bolus in Neck of Femur Fracture
Trial Parameters
Brief Summary
Pericapsular Nerve Group Block (PENG) is an effective regional anaesthesia modality in providing analgesia following neck of femur fracture. Continuous PENG techniques, using indwelling catheters and infusions of local anaesthetic, facilitate the continuation of analgesia for a number of days following hip fracture surgery. It is unclear from the published literature whether an optimal strategy of local anaesthetic delivery has been characterized. Similar doses of local anaesthetic agents can be administered by either continuous infusion or timed intermittent bolus. It is unclear whether one dosing strategy is superior to the other in the context of hip fracture analgesia. The study aims to evaluate the clinical efficacy of both dosing strategies in patients undergoing hip fracture surgery.
