Background
Ultrasound-guided erector spinae plane block has been reported to reduce postoperative pain following a laparoscopic surgery, which is one of the most common abdominal surgeries. The case reports and randomized controlled trials published previously mostly used bilateral erector spinae plane block; however, we report a case in which a unilateral erector spinae plane block was performed.
Case presentation
A 34-year-old male patient who underwent laparoscopic cholecystectomy was scheduled for a unilateral erector spinae plane block. The block was performed preoperatively, followed by the induction of general anesthesia.
Conclusions
The patient was comfortable and had a visual analog scale score of 2 for 12 h. Thus, we report successful pain management with the unilateral erector spinae plane block; however, more studies are needed for conclusive information.
