Surgical sterilisation is currently the method of choice for controlling free-roaming dog populations. However, there are significant logistical challenges to neutering large numbers of dogs in low-resource clinics. The aim of this study was to investigate the incidence of short-term surgical complications in a low-resource sterilisation clinic which did not routinely administer post-operative antibiotics. The medical records of all sterilisation surgeries performed in 2015 at the Worldwide Veterinary Service International Training Centre in Tamil Nadu, India were reviewed (group A) to assess immediate surgical complications. All animals in this group were monitored for at least 24 h post-surgery but were not released until assessed by a veterinarian as having uncomplicated wound healing. In the second part of this study from August to December 2015, 200 free-roaming dogs undergoing sterilisation surgery, were monitored for a minimum of 4-days post-surgery to further assess postoperative complications (group B).
Surgery related complications were seen in 5.4% (95%CI, 4.5-6.5%) of the 1998 group A dogs monitored for at least 24 h, and in 7.0% (3.9-11.5%) of the 200 group B dogs monitored for 4 days. Major complications were classed as those requiring an intervention and resulted in increased morbidity or mortality. Major complications were seen in 2.8% (2.1-3.6%) and 1.5% (3.1-4.3%) of group A and B, respectively. Minor complications requiring little or no intervention were recorded for 2.6% (1.9-3.4%) for group A and 5.5% (2.8-9.6%) for group B. There was no evidence for a difference in complication rates between the two groups in a multivariate regression model.
This study demonstrated that high volume, low-resource sterilisation of dogs can be performed with a low incidence of surgical complications and low mortality.
手术绝育是目前控制流浪狗数量的首选方法。然而，在资源匮乏的诊所对大量狗进行绝育手术存在重大后勤挑战。本研究的目的是调查一家资源匮乏的绝育诊所中短期手术并发症的发生率，该诊所通常不使用术后抗生素。回顾了2015年在印度泰米尔纳德邦全球兽医服务国际培训中心进行的所有绝育手术的病历（A组），以评估即时手术并发症。该组所有动物术后至少监测24小时，但直到兽医评估伤口愈合无并发症后才被放行。在本研究的第二部分，2015年8月至12月，对200只接受绝育手术的流浪狗术后至少监测4天，以进一步评估术后并发症（B组）。
在至少监测24小时的1998只A组狗中，5.4%（95%CI，4.5 - 6.5%）出现手术相关并发症，在监测4天的200只B组狗中，7.0%（3.9 - 11.5%）出现手术相关并发症。主要并发症被定义为需要干预且导致发病率或死亡率增加的并发症。A组和B组分别有2.8%（2.1 - 3.6%）和1.5%（3.1 - 4.3%）出现主要并发症。A组有2.6%（1.9 - 3.4%）、B组有5.5%（2.8 - 9.6%）记录了几乎不需要或不需要干预的轻微并发症。多变量回归模型中两组并发症发生率无差异。
本研究表明，对狗进行大量、资源匮乏的绝育手术，手术并发症发生率低，死亡率也低。
