Abstract

Lumbar Erector Spinae Plane Block for Total Hip Arthroplasty: A Comparison of 24-Hour Opioid Requirements. Materials and Methods: Patients between the ages of 20 and 75 who elected to have a primary unilateral total hip arthroplasty performed under spinal anesthesia by one of the collaborating surgeon co-investigators. Initial eligibility determinations for participants were made by the lead investigator, while the research staff was responsible for making phone calls, recruiting individuals, enrolling them, and obtaining written permission. Results: The main goal was unsuccessful in demonstrating that the combination of ESPB with spinal anesthesia is superior to spinal anesthesia alone on 24-hour postoperative opioid intake when compared to spinal anesthesia alone. In the ESPB group, the average daily use of opioids was 1088 mg, whereas in the control group, the average daily consumption was 1408 mg (p = 0.11). However, the control group had a considerably greater median opioid intake than the ESPB group in the first 8 hours postoperatively, 480 mg OME against 96 mg OME (p = 0.02). At 48 hours postoperative, there was no statistically significant difference in the amount of opioid intake between the two groups (1120 mg and 1420 mg OME in the ESPB group and the control group, respectively) (p=0.47). Conclusion: We came to the conclusion that there is potential advantage of lumbar ESPB in lowering the amount of opioids needed in the first eight hours after hip arthroplasty but not beyond that. Our findings at the 24-hour mark are equivocal because of the limited size of the sample we used and the widespread dispersion of the opioid data.
