Obstetrical Management of Partial Uterine Prolapse in a Mare

Uterine Prolapse is termed as the eversion of the uterus or casting of ‘’wethers’’ or casting of calf bed. It is a common complication of the third stage of labor and more common in pleuripara than primipara. Uterine prolapse is common in cows and ewes, but rarely seen in mares, dogs, and cats. A six-year-old female pony was brought to the emergency unit at the Obstetrics Unit of Veterinary Clinical Complex, Veterinary College and Research Institute Orathanadu, with a history of aborted pre-term (eight months) a day before and the mass hanging through the vulva. On clinical examination, the animal was dull and in a standing posture, the congested mucous membrane with tachycardia was noticed. Further examination of the mass revealed severe congestion and edema of the prolapsed uterus with no evidence of fetal membrane remnants. A vaginal examination explored constricted cervix. Blood samples were collected for hematology and serum biochemistry. Upon epidural anesthesia, the prolapsed mass was washed with potassium permanganate solution and then a hypertonic solution. After 10 minutes, the mass was washed with warm normal saline. Using Cetrimide cream as a lubricant and an antiseptic, the mass was reduced and repositioned. No Buhner’s suture was applied. Mare has received 40 IU of oxytocin for the involution process to begin. Systemic antibiotics and anti-inflammatory drugs were administered for five days. Uterine lavage was done for three days with normal saline and povidone-iodine to aid in uterine clearance. On consequent days, the mare had improved and the cervix was closed with no discharge. The mare had an uneventful recovery.
