Overview
Brief Summary
The purpose of this study was to investigate the effectiveness of erector spinae plane block on postoperative visceral pain in laparoscopic cholecystectomy (LLC). Given that rectus sheath block may provide sufficient somatic pain block, investigators aimed to investigate whether erector spinae block is effective in visceral pain block.
After induction of general anesthesia, group of patient is decided randomly. In Group R, rectus sheath block is performed with 0.2% Ropivacaine 30ml before the operation. In Group RE, rectus sheath block and erector spinae plane block are performed with 0.2% ropivacaine 70ml before the operation.
NRS score measurement and comparison of the rescue analgesic dose used at 0, 0.5, 1, 2,6, 12, 18, and 24 hours after arrival at the recovery room were collected

Outcomes
Primary Outcomes
Difference of analgesic consumption between both group
Time Frame: at 0, 0.5, 1, 2, 6, 12, 18, 24 hours after operation
The difference in analgesics usage between the two groups after the operation is checked at fixed intervals (at 0, 0.5, 1, 2, 6, 12, 18, 24 hours after operation) to compare.
Secondary Outcomes
- compare the Numeric rating scale (NRS)(at 0, 0.5, 1, 2, 6, 9, 18, 24 hours after operation)
