COMPARATIVE ASSESSMENT OF THE EFFICACY OF TWO DOSES OF 0.25% BUPIVACAINE FOR PERICAPSULAR NERVE BLOCK FOR POSITIONING SUBJECTS FOR A SUBARACHNOID BLOCK FOR HIP FRACTURE SURGERY

Abstract

Background: PENG (peri-capsular nerve block) is an ultrasound-guided nerve block procedure that is commonly used to provide regional anesthesia in patients with hip fractures. 

Aim: The current study sought to compare the efficacy of two doses of 0.25% bupivacaine (15 mL and 20 mL) for pericapsular nerve block in ultrasound-guided PENG block for positioning participants for subarachnoid block for hip fracture surgery.

Methods: The research examined 120 patients receiving hip fracture surgery under subarachnoid block. The PENG block was performed using an ultrasound-guided technique with individuals lying supine. The individuals were separated into two groups of 60 each, with Group I receiving 20 mL of 0.25% bupivacaine and Group II receiving 15 mL. The simplicity of placing the individuals was evaluated and contrasted when administering subarachnoid block. Pain was measured in two groups using VAS at rest and 15-degree leg lifts at baseline, 10, and 20 minutes after the block. 

Result: Group I had a substantially higher mean ease of placement for subarachnoid block (2.45±0.75, 95% CI 2.172.67) than Group II (1.84±0.64, 95% CI 1.63-2.3, p=0.001). Group I showed a substantial decrease in pain levels using VAS compared to Group II at rest and 15 leg lift postures at all evaluation periods (p<0.05). Conclusions: The current study found that 20 mL of 0.25% bupivacaine produced better surgical results than 15 mL of 0.25% bupivacaine in terms of patient placement during subarachnoid block during hip fracture procedures.  Keywords: analgesia, anesthetic, bupivacaine, ease of positioning, hip fractures, and PENG
