Objective:To compare intraoperative physiologic variables and post-operative pain associated with lift laparoscopy and conventional capnoperitoneum laparoscopy.Study Design:Prospective randomized case controlled study.Animals:Healthy dogs (n = 30).Methods:Dogs having laparoscopic ovariohysterectomy were randomly assigned to lift laparoscopy (n = 14) or capnoperitoneum (16) laparoscopy. Physiologic variables measured intraoperatively were documented. Postoperatively, pain response was assessed in a blinded fashion using the short Glasgow pain scale and von Frey filament aesthesiometry.Results:Lift laparoscopy was associated with less frequency of hypercapnia, required less anesthetic gas, and was not more time-consuming or painful than capnoperitoneum laparoscopy.Conclusions:Lift laparoscopy is a feasible alternative to capnoperitoneum laparoscopy, especially in dogs where pressurized capnoperitoneum is not desired.
