Popis: Background and Aims: Regional anaesthesia has been used to reduce acute post-operative pain as well as opioid-related side effects in breast cancer surgery. Erector spinae plane (ESP) block is a relatively new fascial plane block being tried in various surgical procedures. Our study is a double-blind randomised trial, designed to prove the efficacy of this block in breast surgeries. Methods: Seventy female patients scheduled for unilateral breast surgery were enroled in this prospective, randomised, double-blind study. Patients were randomised to group A and group B. All patients received general anaesthesia while group B received additional ultrasound-guided erector spinae block given at thoracic level—T5 with 20ml of 0.25% bupivacaine. Time to first rescue analgesia was the primary outcome. Secondary outcomes were total intraoperative opioid consumption, pain scores over 24 h, post-operative nausea and vomiting and patient satisfaction score at discharge. The Shapiro–Wilk test was used to check the normality of each variable. A comparison was done using Mann–Whitney test and the level of significance was set at 0.05. Results: The median time to first rescue analgesia in group A versus group B was 1 h (1–12h) versus 8 h (1–26h), respectively, with a P value of 0.044. Group B patients had lower pain scores post-operatively and better satisfaction scores at discharge. There was no statistically significant difference in intraoperative fentanyl consumption. Conclusion: Ultrasound-guided ESP block with general anaesthesia offers superior post-operative analgesia compared to general anaesthesia alone in patients undergoing unilateral nonreconstructive breast cancer surgeries.
