Efficacy of perioperative analgesia with pericapsular nerve group block combined with lateral femoral cutaneous nerve block in elderly patients with hip fractures
Objective To observe the efficacy of perioperative analgesia with pericapsular nerve group(PENG)block combined with lateral femoral cutaneous nerve(LFCN)block in elderly patients with hip fractures.Methods Sixty elderly patients undergoing open reduction and internal fixation for hip fractures under subarachnoid block were randomly divided into two groups with 30 cases each.Group P received ultrasound-guided PENG block alone and group PL received additional ultrasound-guided LFCN block.The VAS pain scores of two groups were recorded before nerve block(T0),and 5 minutes(T1),10 minutes(T2)and 20 minutes(T3)after block at both resting and activity states,as well as in subarachnoid block positioning(T4)at activity states.The VAS pain scores were evaluated at 6,12,24 and 48 hours postoperatively.The numbers of effective patient-controlled analgesia(PCA)compression and total compression and the consumption of oxycodone were recorded within 48 hours postoperatively.Results The resting VAS pain scores of two groups at T1 to T3 were lower than those at T0(P＜0.05).The activity VAS pain scores of two groups at T1 to T4 were lower than those at T0(P＜0.05).The resting and activity VAS pain scores at 6,12,24,48 hours postoperatively were lower in group PL than those in group P(P＜0.05)The effective PCA compression number and total PCA compression number and dosage of oxycodone within 48 hours after surgery were all less in group PL than those in group P(P＜0.05).Conclusion Compared with PENG block alone,combined use of PENG block and LFCN block has a better perioperative analgesic efficacy in elderly patients with hip fractures.
