Clenbuterol (Ventipulmin® Solution) was included in the corrective management of dystocia cases requiring obstetrical surgery encountered in a Quebec rural practice. Data were collected on a total of 69 cases: 63 bovine and three ovine caesareans, and three bovine fetotomies. Ease of exteriorization of the gravid uterus and postoperative development of uterine adhesions were compared in two groups of bovine caesarean cases: a clenbuterol-treated group (Group A, n = 63) and a nontreated control group (Group B, n = 90). Clenbuterol produced a potent myometrial relaxant effect making its use beneficial in the correction of the bovine and ovine dystocias. It provided significantly improved uterine maneuverability (×2 = 47.63, P < 0.001) and significantly reduced postoperative development of adhesions (×2 = 14.05, P < 0.001) except in bovine caesarean cases with a high degree of myometrial distension. Neonatal and maternal health were not impaired and retention of fetal membranes was not increased. When used as directed, clenbuterol was a safe, reliable, and efficacious drug.
