This report presents a case of uterine prolapse in a Thoroughbred mare. The uterine prolapse occurred after abortion of twins in the eighth month of gestation. The prolapsed uterus was bleeding and congested but not damaged. The placenta was still attached to the endometrium. Blood samples were collected for hematology and for estimation of calcium, progesterone and estrogen. The cervix and clitoris were swabbed for bacteriology. The mare showed a decrease in the number of lymphocytes. The concentrations of estrogen and progesterone seemed normal compared with mares that foaled. Pseudomonas aeruginosa was isolated. The prolapsed uterus was washed with warm normal saline, and the retained placenta was carefully removed. An antibiotic cream was spread on the prolapsed uterus before replacing it. Two-thirds of the upper vulva was transiently sutured. Systemic antibiotics and an anti-inflammatory were administrated for 5 days. After 24 hr, the sutures were removed, and uterine lavage was performed using warmed normal saline for three days. The mare received 20 IU of oxytocin twice a day for three days to aid uterine clearance. A local antibiotic was inserted into the uterus. After treatment, the mare did not show any health disorders. She entered estrus 9 days after abortion and again 10 days later. In conclusion, twin pregnancy in a mare is considered a critical condition that necessitates specific management during early and late pregnancy. Uterine prolapse is an emergency that should be treated in a skilled manner to protect the mare and her future fertility. Calcium deficiency might predispose mares to uterine prolapse.
本报告介绍了一匹纯种母马子宫脱垂的病例。子宫脱垂发生在妊娠第八个月双胞胎流产之后。脱垂的子宫有出血和充血现象，但未受损。胎盘仍附着于子宫内膜。采集血样进行血液学检查以及钙、孕酮和雌激素水平测定。擦拭子宫颈和阴蒂进行细菌学检查。该母马淋巴细胞数量减少。与已产驹的母马相比，雌激素和孕酮浓度似乎正常。分离出铜绿假单胞菌。用温生理盐水冲洗脱垂的子宫，并小心清除残留的胎盘。在将脱垂的子宫复位之前，在其上涂抹抗生素乳膏。暂时缝合三分之二的上外阴。给予全身抗生素和消炎药，持续5天。24小时后拆除缝线，用温生理盐水进行子宫灌洗，持续三天。母马每天两次接受20国际单位的催产素，持续三天，以促进子宫排空。向子宫内插入局部抗生素。治疗后，母马未出现任何健康问题。流产后9天进入发情期，10天后再次发情。总之，母马怀双胞胎被认为是一种危急情况，在妊娠早期和晚期需要进行特殊管理。子宫脱垂是一种紧急情况，应以熟练的方式进行治疗，以保护母马及其未来的生育能力。钙缺乏可能使母马易患子宫脱垂。
