Pericapsular Nerve Group (PENG) Block and Lateral Femoral Cutaneous Nerve (LFCN) Block Versus Fascia Iliaca (FIC) Block for Multimodal Analgesia After Total Hip Replacement Surgery: a Retrospective Analysis Focused on Movement (Retro- PvF)
Pericapsular Nerve Group (PENG) Block and Lateral Femoral Cutaneous Nerve (LFCN) Block Versus Fascia Iliaca (FIC) Block for Multimodal Analgesia After Total Hip Replacement Surgery: a Retrospective Analysis Focused on Movement (Retro- PvF)
Total hip arthroplasty is a major surgical procedure performed on a growing number of patients. Optimal pain control with limited muscle weakness is paramount for a swift initiation of physical therapy and ambulation, thus expediting hospital discharge. Amongst the many peripheral nerve blocks, FIB (fascia iliaca block) has been recommended as the block of choice by many international guidelines since it offers the best pain control with a relatively low risk of motor block. PENG (pericapsular nerve group) and its association with LFCN (lateral femoral cutaneous nerve) has been proposed as an effective alternative that offers comparable, If not better, pain control with a considerably lower risk for motor block compared to FIB. Given the novelty of this block, there are few published papers on the subject, mostly case series or case reports thus justifying the need for retrospective study.
The primary outcome was the degree of residual quadriceps femoris muscle paresis assessed with the MRC (medical research council) scale at 6 hours between PENG and LCFN. The secondary outcomes were NRS (numeric rating scale) at 6,12, 24 hours, total opioid consumption expressed as milligrams of morphine equivalents (MME), time to first rescue opioid and time to first postoperative ambulation.
