Risk factors associated with gastrointestinal dysfunction in horses undergoing elective procedures under general anaesthesia.
Abstract: Gastrointestinal dysfunction occurs commonly following elective anaesthesia. Identification of risk factors may allow implementation of preventative measures to reduce the prevalence of colic following elective anaesthetic procedures. Objective: To examine risk factors associated with gastrointestinal dysfunction or post anaesthetic colic for horses undergoing elective surgical or diagnostic procedures under general anaesthesia. Methods: Retrospective case series. Methods: Medical records were collected from adult horses undergoing general anaesthesia from 1 January 2008 to 31 December 2010 using a retrospective cohort design. Potential risk factors were examined using univariable logistic regression with a limit of a P<0.25. Through backward elimination, the final multivariate model was created to identify variables significantly associated with gastrointestinal dysfunction. Results: Colic or delayed faecal output was reported in 36 out of 416 (8.7%) horses undergoing general anaesthesia in the study period. In the final multivariable model, horse breed (P = 0.05), intraoperative peripheral blood lactate (P = 0.02), right lateral recumbency during general anaesthesia (P = 0.04), post anaesthetic rectal temperature (P = 0.03) and hours to first passage of faeces (P<0.01) were statistically significant between horses that exhibited colic compared with those that did not. Arabians were more likely to develop colic compared with other horse breeds (4/13, 30.8%). Horses that exhibited gastrointestinal dysfunction passed faeces later than those that did not (7.2 ± 0.8 h and 5.4 ± 0.2 h, respectively). As blood lactate increased at the end of anaesthesia, the odds of colic occurring also increased (odds ratio:1.4, 95% confidence interval: 1.04-1.83, P = 0.02). Conclusions: This study demonstrated the prevalence of colic in horses undergoing elective general anaesthetic procedures in our hospital population. Arabian horses, increasing blood lactate and delayed passage of faeces were significantly associated with an increased risk of gastrointestinal dysfunction.

The research explores the relationship between various risk factors and the occurrence of gastrointestinal dysfunction, also known as colic, in horses that undergo elective surgical or diagnostic procedures under general anesthesia. The data suggest that Arabian horse breed, increased blood lactate, and delayed passage of faeces are significantly related to an increased risk of experiencing gastrointestinal issues post-anaesthetic.
Objective and Methodology
- The primary aim of this research was to evaluate the risk factors associated with gastrointestinal dysfunction in horses who had undergone elective surgical or diagnostic procedures under general anesthesia. This was done in the hope that the identification of these risk factors may allow for the establishment of preventative measures to curb the prevalence of colic following sedation.
- The chosen methodology was a retrospective case series. The research examined medical records of adult horses that had been put under general anaesthetic from 1st January 2008 to 31st December 2010.
- The potential risk factors were evaluated using a univariate logistic regression. The final multivariate model was created via backward elimination to indicate the variables significantly relating to gastrointestinal dysfunction.
Results
- Colic or delayed faecal output was observed in 36 out of 416 (8.7%) horses that were put under general anesthesia within the study period.
- The breed of the horse, intraoperative peripheral blood lactate, the horse’s position (right lateral recumbency) during anesthesia, post anesthetic rectal temperature, and hours until the first passage of faeces were all found to be statistically significant factors between horses that demonstrated colic compared to those that did not.
- Arabian horses were found to be more susceptible to developing colic compared to other breeds.
- Horses that experienced gastrointestinal dysfunction passed faeces noticeably later than horses that did not.
- The odds of a horse experiencing colic increased as the blood lactate level increased at the end of the anaesthesia.
Conclusions
- The research established that the practice of elective general anaesthetic procedures is accompanied by a prevalence of colic in horses in the studied hospital population.
- Specific risk factors such as being of the Arabian breed, having an increased blood lactate level, and experiencing a delayed passage of faeces were found to be strongly associated with an increased risk of gastrointestinal dysfunction.
