- Systematic Review
Summary
This research article provides a systematic review of studies conducted from 2000-2023 on post-operative complications in horses after general anaesthesia. The study found that such complications are prevalent and significantly higher after colic surgery compared to non-abdominal, elective surgeries.
Research Methodology
The researchers embarked on the study by searching databases for prior relevant researches. Their criteria included:
- Studies that reported the prevalence of post-operative complications in horses.
- These studies had to be published between 2000 and 2023 as a full paper in English.
- The papers also had to be peer-reviewed and published in a journal.
The studies found were critically evaluated using two major tools:
- JBI Critical Appraisal Checklist for Prevalence Studies: This tool is used to assess the authenticity, robustness, and applicability of a study involving prevalence data.
- The GRADE (Grading of Recommendations, Assessment, Development and Evaluations) framework: This tool is used to evaluate the quality of evidence in a research piece and the strength of its recommendations.
Results Analysis
Data analysis from the 67 studies that met the eligibility criteria entailed using Chi-squared analysis of weighted means. This method helped answer 13 PICO (Population, Intervention, Comparator and Outcomes) questions. The most common procedural aftermaths scrutinised were:
- Colic
- Surgical site complications
- Myopathy/neuropathy
- Laminitis
- Diarrhoea/colitis
- Fever/pyrexia
- Jugular thrombophlebitis/thrombosis
- Respiratory complications
Study Findings
The result highlights that the overall prevalence of post-operative complications after elective/non-abdominal surgery is about 17.48%, but this rises significantly to 55.62% after colic surgery. The complication reported most was post-operative colic. Following elective/non-abdominal surgery, the weighted mean prevalence of surgical site complications, laminitis, diarrhoea/colitis, fever/pyrexia, jugular thrombophlebitis/thrombosis and respiratory complications were found to have significantly increased after colic surgery. However, the prevalence of myopathy/neuropathy showed no significant difference between the groups.
Conclusion
The data used in this study was largely drawn from retrospective studies. The definitions for morbidity, data collection periods, follow-up times, and methods varied across the studies, which could have had an impact on findings. Despite this, the study concludes that post-operative colic, surgical site complications, laminitis, diarrhoea/colitis, fever/pyrexia, jugular thrombophlebitis/thrombosis, and respiratory complications are prevalent and significantly higher after colic surgery, as opposed to elective/non-abdominal surgery performed under general anaesthesia.
