BACKGROUND: Ultrasound-guided quadratus lumborum block (QLB 2) and erector spinae plane block (ESPB) were suggested to prevent somatic and visceral pain in a small number of abdominal surgeries. In this study, we aimed to compare these fascial plane blocks in terms of efficacy and safety in patients undergoing open nephrectomy.
METHODS: This double-blind randomized controlled trial included a total of 40 patients (aged 18-70 years, with an ASA Score of I-III) and underwent partial or radical nephrectomy with subcostal incision. Unilateral ESPB and QLB 2 were performed at the end of the operation. The patients were then assessed for total morphine consumption, pain scores, and side effects at the postoperative 24^th hour.
RESULTS: The ESPB and QLB 2 groups showed similar total morphine consumption (20.95+12.40 mg and 25.05+13.60 mg, P=0.870) and morphine demands (37.85+29.43 and 41.15+31.75, P=1.000), respectively. Despite the lower VAS scores at rest and movement in the ESPB group, there were no statistically significant differences between groups.
CONCLUSIONS: Ultrasound-guided QLB 2 and ESP block were found to achieve similar results on at rest and at movement pain scores and morphine consumption of the patients undergoing open nephrectomy. Both blocks may be preferred, depending on the clinician’s experience.
