Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group 1: Deep neuromuscular blockade with bolus intraveneous 1 mg/kg rocuronium for 8 mmHg intraabdominal pressure for pneumoperitoneum at the beginning of the procedure. 5% carbon dioxide (CO2) at 37 degrees Celsius and 50% humidity was used for pneumoperitoneum from time of incision to time of closure of the abdomen. 0.1-0.2 mg/kg rocuronium was administered multiple doses at clinical discretion of anaesthetist to maintain deep neuromuscular blockade during surgery if post-tetanic count >1. Group 2: moderate neuromuscular blockade with bolus intraveneous 0.5 mg/kg rocuronium for 12 mmHg intraabdominal pressure for pneumoperitoneum at the beginning of the procedure. 5% carbon dioxide (CO2) at 37 degrees Celsius and 50% humidity was used for pneumoperitoneum from time of incision to time of closure of the abdomen. No further rocuronium was administered for moderate blockade.

Summary
Brief summary
We assessed the postoperative pain scores with 11 point numeric rating scale for deep and moderate muscle blockade after laparoscopic cholecystectomy. In addition we assessed the surgical space conditions during surgery with 4-point scale and numeric rating scale.

Public notes
ethics approval was not attained prior to recruitment of the first participant. because our ethical comitee did not approved. Then we finished the recruitment, they approved the study so ethical comitee date was late.
