Erector spinae plane block vs non-steroidal anti-inflammatory drugs for severe renal colic pain: A pilot clinical feasibility study.

Aim: Ultrasound-guided plane blocks are increasingly used in the multi-modal analgesic concept for reducing opioid consumption. The present study was conducted to compare the analgesic effect of intravenous non-steroidal anti-inflammatory drugs (NSAIDs) and erector spinae plane (ESP) block in renal colic patients.

Methods: In this prospective randomised study, 40 patients with renal colic pain were randomly assigned into two groups: Group NSAID (n = 20) received an intravenous infusion of 50 mg of dexketoprofen trometamol and Group ESP (n = 20) received ultrasound-guided ESP block with 30 ml 0.25% bupivacaine at the T8 level. The pain severity of patients was assessed using the visual analogue scale (VAS) at baseline, 5, 15, 30, 45 and 60 minutes after intervention. Opioid consumption, patient satisfaction and side effects were recorded.

Results: In the ESP group, the VAS scores were significantly lower than the NSAID group at 5, 15, 30, 45 and 60 minutes after the procedure (P < .001). Opioid consumption was significantly higher in the NSAID group compared with the ESP group (10/20 vs 0/20, respectively; P < .001). Patient satisfaction was significantly higher in the ESP group (P < .001).

Conclusions: ESP block can be an alternative, efficient and safe method for the relief of acute renal colic pain.
