The Visceral Analgesic Effect of Erector Spinae Plane Block in Laparoscopic Cholecystectomy

Asan Medical Center60 enrolled

Overview

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

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.

Time frame: at 0, 0.5, 1, 2, 6, 12, 18, 24 hours after operation

Secondary Outcomes

compare the Numeric rating scale (NRS)

10 years old or older. 0: No pain, 1-3: mild pain, 4-6: Moderate pain, 7-10: severe pain, 10: worst pain imaginable. After surgery, the NRS differences between the two groups were compared at a constant interval (0, 0.5, 1, 2, 6, 12, 18, 24 hours postoperatively).

Time frame: at 0, 0.5, 1, 2, 6, 9, 18, 24 hours after operation
