The Use of Erector Spinae Plane Block Reduces Opioid Consumption and Pain Score in Postoperative Period After Hip Surgery: A Meta-Analysis

Erector spinae plane block (ESPB) is a relatively new regional anesthesia block that has been used in thoracic and abdominal surgeries with variable success. ESPB can easily be administered using an ultrasound technique with a safer profile. Recently, there have been few randomized controlled trials (RCTs) regarding the role of ESPB in hip surgeries. A current meta-analysis was done to evaluate the role of ESPB block in controlling postoperative pain after hip surgeries. PRISMA guidelines were followed to perform this meta-analysis. We used online databases including Science Direct, PubMed, Google Scholar, and Cochrane Library. This review was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database as ID-CRD42023445516 in July 2023. We included studies that reported opioid use, pain control after surgery, and side effects associated with ESPB for hip surgeries. The ReviewManager software, i.e., RevMan for Mac 5.4 (Cochrane Collaboration, Oxford, UK), was utilized to conduct this meta-analysis. We included five RCTs during this meta-analysis. Our results demonstrated that the use of ESPB in hip surgery caused a significant decrease in 24-hour postoperative opioid consumption (p=0.02). ESPB also resulted in a significant decrease in pain scores up to nine hours postoperatively (p<0.05).
