Comparison of pericapsular nerve group block and fascia iliaca compartment block for analgesia following hip fracture surgery: a meta-analysis / 中华麻醉学杂志

ABSTRACT

Objective:To systematically compare the analgesic efficacy of pericapsular nerve group (PENG) block and fascia iliaca compartment block (FICB) after hip fracture surgery.Methods:Databases including Pubmed, Embase, Cochrane, CNKI, Wanfang and VIP were searched for randomized controlled trials involving comparison of the analgesic efficacy of PENG block and FICB after hip fracture surgery from inception to August 2022. The primary outcome was the postoperative pain score, and the secondary outcome was the amount of postoperative analgesics and incidence of postoperative adverse reactions. The data were analyzed using Revman 5.4 software.Results:Eight studies were included ( n=374), and the pain score at rest 30 min after block was significantly lower in PENG group than in FICB group ( MD=-0.35, 95% CI -0.60--0.11, I2=14%, P<0.05). There was no statistically significant difference between PENG group and FICB group in pain scores at rest and during activity at 6, 12, 24 and 48 h after operation ( P>0.05). Compared with FICB group, the amount of analgesics used was significantly reduced at 24 and 48 h after operation in PENG group ( MD=-9.10, 95% CI -19.11-0.91, I2=95%, P<0.05). There was no statistically significant difference in the incidence of adverse reactions after operation between the two groups ( P>0.05). Conclusions:PENG block provides better efficacy when used for analgesia following hip fracture than FICB.
