title: [Postoperative analgesia for the laparoscopic cholecystectomy].
abstract: BACKGROUND
  As laparoscopic cholecystectomy is assumed to be with less postoperative pain, it is managed only by general anesthesia during the surgery in our hospital. However, about 70 percent of cases needed the additional analgesic drugs after the operation. In addition, about 70 percent needed analgesic drugs within three hours after the operation, and it has been understood that early postoperative analgesia is insufficient. We focused on the ultrasound guided nerve block and used it to relieve postoperative pain after the laparoscopic cholecystectomy.
  
  
  METHODS
  Forty three cases managed by the general anesthesia alone are compared with 9 cases managed with the nerve block of the trunk in for the laparoscopic cholecystectomy.
  
  
  RESULTS
  Pain score early after the operation, the ratio of patient who used analgesic drug, and the frequency of its use are all decreased by performing the block.
  
  
  CONCLUSIONS
  The use of ultrasound guided nervous block for the postoperative pain after laparoscopic cholecystectomy has been helpful, and excellent pain relief has been obtained.
