AbstractAlthough the surgical advantages of laparoscopic cholecystectomy (LC) have been reported, the anaesthetic problems associated with this new technique have not been well described. For the first 101 patients undergoing laparoscopic cholecystectomy at our institution, we prospectively documented intraoperative critical observations and adverse outcomes in the PACU (Post-Anaesthetic Care Unit). In order to put the magnitude of these problems into perspective, we compared, in an identical manner, the anaesthetic management and outcomes of two more familiar surgical groups, cholecystectomy by laparotomy (C), and laparoscopy for gynaecological examination (LG). For this new procedure LC, intraoperative hypotension (12.9%), and PACU hypothermia (31.4%), nausea and vomiting (12.9%) and desaturation (10.9%) were common but excessive pain (4.0%) was rare. Patients undergoing C, who were older and less healthy, tended to have fewer incidents of OR hypotension (3.4%) but in the PACU experienced more desaturation (25.9%) and excessive pain (12.9%) (P < or = 0.05). The younger and healthier LG group had fewer problems, less OR hypotension (0.4%), and less PACU nausea and vomiting (5.7%) and desaturation (1.3%) (P < or = 0.05). However, the LG group had a similar incidence of excessive pain (4.4%). We have documented considerable postoperative anaesthetic benefits for patients undergoing laparoscopic cholecystectomy compared with conventional cholecystectomy. However, there is still considerable perioperative morbidity compared with gynaecological laparoscopies. Now that specific problems have been identified, they may be amenable to specific anaesthetic interventions.
