犬子宫蓄脓：母犬发情后 2 个月内最危险的急症
2026/10/3· 约 4 分钟读完· 27 个要点
未绝育母犬发情后出现多饮多尿、外阴分泌物或精神沉郁，必须排查子宫蓄脓。这篇按 Vet Clin 综述与 Theriogenology 研究讲清识别、为何手术是首选及术后护理。
一、为什么会发生在"发情后"
发情周期中的孕酮作用使子宫内膜增生、宫颈关闭，细菌（常见大肠杆菌）上行感染并在子宫内积脓。所以高发窗口是发情结束后的数周至约 2 个月，中老年未绝育母犬风险更高[1][2]。
二、开放型 vs 闭合型：闭合型更危险
- 开放型：外阴有脓性/血性分泌物，容易被注意到；
- 闭合型：没有外流分泌物，脓液积在子宫内，毒素与脱水进展更快，容易误判为"普通没精神"[1]。
其他信号：多饮多尿、呕吐、食欲废绝、腹围增大、精神沉郁、发热（也可能体温偏低）。

Pyometra is a common disease in intact bitches and queens and occurs, although less frequently, in most other female pets. In bitches and queens, the illness is generally diagnosed within 4 months after estrus, in middle-aged to older individuals. Complications such as peritonitis, endotoxemia, and systemic inflammatory response syndrome are not uncommon and associated with more severe illness. Ovary-sparing surgical options such as hysterectomy could be considered in individuals with high-risk for detrimental side effects of spaying or without infection of the uterus but has not yet been evaluated for safety in pyometra.
