PENG Block: Continuous Infusion vs. Programmed Intermittent Bolus in Neck of Femur Fracture

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.

Outcome Measures
Primary Outcomes (1)
Numeric Rating Pain Scale (NRS 0-10)
Patients will be invited to rate their post operative pain at rest and on movement on a 0-10 scale; where 0 is no pain and 10 is worst imaginable pain.
48 Hours Post-operatively
Secondary Outcomes (2)
Numeric Rating Pain Scale (NRS 0-10)
1, 2, 4, 24 hours postoperatively
Quality of Recovery 15 (QOR15)
48 hours postoperatively
Study Arms (2)
Continuous PENG Infusion
ACTIVE COMPARATORParticipants will be randomly assigned to this arm and will receive a continuous infusion of levobupivacaine.
Programmed Intermittent Bolus PENG
EXPERIMENTALParticipants will be randomly assigned to this arm and will receive a timed pre-set bolus dose of levobupivacaine.
Interventions
Participants in this arm will receive a continuous infusion of levobupivacaine via a regional anaesthesia catheter placed in the PENG fascial space. The total dose over 24 hours will be equivalent in both arms of the study.
Participants in this arm will receive a timed pre-set bolus dose of levobupivacaine via a regional anaesthesia catheter placed in the PENG fascial space. The total dose over 24 hours will be equivalent in both groups.
