An interventional study of Ultrasound guided Rectus sheath block and Intercostal nerve block in Preemptive Peripheral Nerve Block, Pain, Postoperative and Acute Pain, sponsored by Asan Medical Center. Completed at 1 site in Korea, Republic of. Open to participants aged 20 Years to 80 Years. Per ClinicalTrials.gov, last updated 2019-01-23.
Sponsored by Asan Medical Center · Not applicable, Interventional, and Prevention
The purpose of this study was to investigate the effectiveness of preemptive effect of rectus sheath block (RSB) and intercostal nerve block (ICNB) on postoperative visceral pain in laparoscopic cholecystectomy (LLC).
After induction of general anesthesia, group of patient is decided randomly. In Group pre, RSB and ICNB are performed with 0.25% Ropivacaine 40ml before the operation. In Group post, RSB and ICNB are performed with 0.25% Ropivacaine 40ml after the operation.
Measure the NRS and compare the rescue analgesic dose used at 0, 0.5, 1, 2, 6, 9, 18, and 24 hours after arrival at the recovery room.
Exclusion Criteria:
ultrasound guided Rectus sheath block block with 0.25% ropivacaine 40ml Before surgical incision
Drug: Ultrasound guided Rectus sheath block · Drug: Intercostal nerve block
ultrasound guided Rectus sheath block block with 0.25% ropivacaine 40ml After surgical incision
Drug: Ultrasound guided Rectus sheath block · Drug: Intercostal nerve block
Ultrasound guided rectus sheath block with 0.25% ropivacaine 34ml around umbilicus
Ultrasound guided intercostal nerve block with 0.25% ropivacaine 6ml in 7,8,9 th intercostal space
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, 9, 18, 24 hours after operation) to compare.
Time frame: at 0, 0.5, 1, 2, 6, 9, 18, 24 hours after operation
compare the Numeric rating scale (NRS)
The Numeric Rating Scale (NRS-11) is an 11-point scale for patient self-reporting of pain. It is for adults and children 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, 9, 18, 24 hours postoperatively).
Time frame: at 0, 0.5, 1, 2, 6, 9, 18, 24 hours after operation
