Post-operative morbidity associated with the use of atracurium and vecuronium in day-case laparoscopy.

: Patients were randomly allocated to receive either vecuronium or atracurium as the sole muscle relaxant for day-case gynaecological laparoscopy to determine if either agent was superior with respect to post-operative morbidity during the 48 h after operation. Intubating conditions and cardiovascular stability were similar in both groups. Post-operative morbidity prior to discharge was also similar except for a significantly higher incidence of abdominal pain in the vecuronium group. There was no statistical difference in specific morbidity during the 48 h after laparoscopy, but a greater number of patients in the vecuronium group was able to resume normal activity 24 h after laparoscopy. Both agents are very suitable for day-case laparoscopies and other short surgical procedures.
