Efficacy of Lumbar Erector Spinae Plane Block for Postoperative Analgesia in Hip Arthroplasty Patients– A Prospective Case Series

The Thoracic Erector spinae plane block (ESPB) has been incorporated in multimodal analgesia protocols since 2016. In a series of 20 Total Hip Arthroplasty (THA) patients, done under spinal anaesthesia, we studied the efficacy of Lumbar Erector spinae plane block (L-ESPB) for post operative analgesia. L-ESPB was administered at L4 with Ropivacaine 0.2% (0.4 mg/kg). Time to first analgesia (TTFA) request (mean 15.03 hours) and total opioid consumption in first 24 hours (mean 27.5 mg Tramadol) was noted. A median NRS at TTFA was 3.5. Our study demonstrates L-ESPB as an effective alternate technique for postoperative analgesia in THA patients. Keywords: Lumber ESP block, Hip Arthroplasty
