Clinical records of all 212 ewes undergoing emergency caesarean surgery at a veterinary teaching hospital between January 2008 and December 2019 were evaluated retrospectively. Their age ranged from 1 to 10 years (median = 4 years), with German merino the predominant breed (48.1% of cases). The most frequently diagnosed indications were insufficient cervical dilatation (n = 94, 44.3%), uterine torsion (n = 50, 23.6%), foetopelvic disproportion (n = 31, 14.6%) and vaginal prolapse intra partum (n = 11, 5.2%). Fifty‐four (25.5%) of the 212 ewes additionally suffered from one or more concurrent, pre‐existing conditions. Overall ewe mortality until hospital discharge was 10.8% (23/212), and 3.8% (n = 6) for the 158 ewes without a history of concurrent disorders. Mortality during hospitalization increased to 31.5% (17/54) for those with pre‐existing conditions. Total lamb mortality was 49.1% (173/352) until hospital discharge. Pre‐existing conditions (p = .001) and the presence of post‐surgical complications (p = .025) were identified as significant factors influencing dam mortality, while delayed presentation for veterinary attention with an observed duration of labour of >12 hr was identified as the most influential factor on total lamb mortality (p = .010). The presence of dead or emphysematous foetuses was not significant for ewe mortality. Follow‐up information on further outcomes was available for 156 (82.5%) of the 189 discharged ewes. Eighty‐nine animals (57.1%) were re‐bred in the following season and achieved a 93.3% (83/89) pregnancy rate, while the remainder had either been slaughtered (n = 56, 35.9%), sold (n = 5, 3.2%) or had died of unknown causes (n = 3, 1.9%). The subsequent incidence of dystocia was 15.6% (n = 12) in the 77 ewes with available information on lambing ease. Adequate management of underlying conditions and timely intervention are important factors for best possible short‐term outcomes. In the long term, the subsequent pregnancy rate was good and the incidence of subsequent dystocia was within the normal range.

进行紧急剖腹产的绵羊的母羊和羔羊存活率及随后的繁殖性能相关因素

回顾性评估了2008年1月至2019年12月期间在兽医教学医院接受急诊剖宫产的所有212头母羊的临床记录。他们的年龄从1到10岁（中位数= 4岁），其中德国美利奴羊是主要品种（48.1％的病例）。最常诊断指征为宫颈扩张不足（Ñ  = 94，44.3％），子宫扭转（Ñ  = 50，23.6％），foetopelvic歧化（Ñ  = 31，14.6％）和阴道脱垂帧内产后（Ñ  = 11，5.2 ％）。212头母羊中有五十四（25.5％）名同时患有一种或多种并存的疾病。出院前的总体母羊死亡率为10.8％（23/212）和3.8％（n = 158头没有并发疾病史的母羊。已有疾病的患者的住院期间死亡率增加至31.5％（17/54）。出院前，羔羊总死亡率为49.1％（173/352）。既往病情（p  = .001）和术后并发症（p  = .025）被认为是影响大坝死亡率的重要因素，而观察到的劳动时间超过12 hr则延迟了兽医的诊治时间。被确定为影响羔羊总死亡率的最主要因素（p = .010）。死亡或气肿性胎儿的存在对母羊死亡率并不重要。189头母羊中有156头（82.5％）获得了关于进一步结果的后续信息。在接下来的季节再繁殖了89只动物（57.1％），并实现了93.3％（83/89）的怀孕率，而其余动物则被屠宰了（n  = 56，35.9 ％），出售了（n  = 5 （3.2％）或死于不明原因（n  = 3，1.9％）。随后的难产发生率为15.6％（n = 12）在77头母羊中提供有关产羔缓解的可用信息。对基本情况的充分管理和及时干预是实现最佳短期结果的重要因素。从长期来看，随后的妊娠率良好，并且难产的发生率在正常范围内。
