Cardiorespiratory Changes and Pain Response of Lift Laparoscopy Compared to Capnoperitoneum Laparoscopy in Dogs.

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.
