Analgesic efficacy of erector spinae plane block in percutaneous nephrolithotomy : A randomized controlled trial.
The postoperative pain in percutaneous nephrolithotomy (PCNL) is due to dilatation of the renal capsule and the parenchymal tract. The aim of the study was to evaluate the analgesic effect of preoperative single-shot ultrasound(US)-guided erector spinae plane block (ESPB) at theT11 vertebral level in patients undergoing PCNL. ⋯ The use of US-guided ESPB provides a good postoperative analgesia and decreases opioid consumption over 24 h in patients undergoing PCNL.
