The analgesic efficacy of erector spinae plane block for percutaneous nephrolithotomy: a systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION

The analgesic efficacy of erector spinae plane block (ESPB) for postoperative analgesia after percutaneous nephrolithotomy(PCNL).

METHODS

We searched Pubmed, Embase, Cochrane library, the Chinese Biomedical Literature Database, and randomized controlled trials (RCTs) assessing analgesic efficacy of ESPB for PCNL are included in this meta-analysis.The related trials met the inclusion criteria were analyzed using RevMan 5.4 and GRADE pro software.

RESULTS

Nine RCTs are included in the meta-analysis showed that ESPB group had significantly lower requirement of opioid consumption (MD-20.66 ,95% CI -34.84 to-6.49;P<0.00001),lower pain scores with ESPB use throughout the 24-hour postop period(MD -0.56,95% CI -0.90 to -0.22;P=0.001) and longer the first rescue time in minutes(MD52.68, 95% CI 8.66 to 96.7,P=0.02) ,in hours (MD11.76, 95% CI 5.59 to 17.92, P=0.0002),respectively.

CONCLUSION

The available evidence suggests that ESPB was an efficient and safe procedure for postoperative pain management in PCNL.
