This meta-analysis compared the efficacy of pericapsular nerve group block combined with lateral femoral cutaneous nerve block (PENG+LFCN) versus fascia iliaca compartment block (FICB) for postoperative pain management and recovery in hip surgery. Sixteen studies were analyzed, revealing that PENG+LFCN resulted in significantly lower resting and dynamic VAS scores, reduced muscle weakness, and shorter time to ambulation.
Key findings
- PENG+LFCN group had lower resting VAS scores (MD = -0.54; p < 0.00001).
- Lower incidence of postoperative muscle weakness in the PENG+LFCN group (OR = 0.10; p = 0.0001).
- Time to first ambulation was shorter by 9.22 hours in the PENG+LFCN group (p < 0.0001).
- Morphine consumption was reduced by 24.22 mg in the PENG+LFCN group (p = 0.001).
Why it matters
Effective postoperative pain management is crucial for enhancing recovery after hip surgery. This study suggests that PENG+LFCN may improve pain control and functional recovery, potentially leading to better patient outcomes within ERAS protocols.
