Effects of Ringer's lactate, medroxyprogesterone acetate, gonadotropin-releasing hormone analogue and its diluent on the prevention of postsurgical adhesion formation in rat models

Fifty adult female rats were randomly divided into five groups. Before the standard surgical procedure which consisted of creating a lesion with electrocautery over the uterus, leuprolide acetate (LA) together with its diluent, the diluent alone and medroxyprogesterone acetate (MPA) were injected to the third, fourth, and fifth groups, respectively. Ringer's lactate (RL) solution was applied intraperitoneally to the second group at the end of the surgery. Group I received no medication. Relaparotomy was performed 3 weeks later to evaluate the adhesions. The mean adhesion scores were (mean +/- SD) 2.6 +/- 0.7, 1.4 +/- 0.8, 0.9 +/- 0.6, 2.3 +/- 0.8, and 0.8 +/- 0.6 in groups I, II, III, IV, and V, respectively. The postsurgical adhesions were significantly less in the groups treated with RL, LA, and MPA.
