Effects of carbon dioxide-saturated normal saline and Ringer's lactate on postsurgical adhesion formation in the rabbit.

Objective: To evaluate the effect of combining carbon dioxide gas (CO 2 ) with normal saline versus CO 2 with lactated Ringer's solution on adhesion formation in the rabbit model. Methods: Sixty New Zealand white rabbits underwent surgery based on a proven experimental adhesion model. Following abdominal closure, the animals were randomly assigned to three groups: Group 1 underwent abdominal CO 2 insufflation only; group 2 underwent abdominal irrigation with CO 2 -saturated normal saline; group 3 underwent abdominal irrigation with CO 2 -saturated lactated Ringer's solution
