Official Title: Efficacy of Intraperitoneal Local Anaesthetic Techniques During Laparoscopic Cholecystectomy: A Double Blind Randomized Controlled Trial

Brief Summary:

Pain following laparoscopic cholecystectomy (LC) results in morbidity and is a barrier to same day discharge. In several trials local anaesthetic (LA) washed over the liver and gall bladder decreases pain. In many patients pain has a strong component attributable to diaphragmatic origin. A wash of LA over the liver and gall bladder is unlikely to provide high levels of analgesia to pain fibres from the diaphragm. The investigators hypothesise that LA injected to the right hemidiaphragm during LC would be more effective than wash.

Methods Double blind randomised controlled trial of 128 consecutive subjects undergoing elective LC. Control -sham injection of diaphragm and sham wash over liver/GB with saline; Test treatment 'subperitoneal LA' - bupivocaine injection/sham wash; Internal control 'topical LA' - sham injection/bupivocaine wash. Primary outcome: pain scores in theatre recovery and the ward. Secondary outcomes: analgesic use, physiological observations, time to eating and mobilising, day case surgery.

Current Primary Outcome: VAS pain score [ Time Frame: 1, 4, 8 hours after operation and at discharge ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Time to ambulation [ Time Frame: following the procedure ]
    The first time the patient gets out of bed and walks following the procedure
  • Same day discharge [ Time Frame: 24 hours ]
  • VRS pain scores [ Time Frame: Every 10 minutes in theatre recovery ]
    Immediately following the operation


Original Secondary Outcome: Same as current
