Preliminary results on the association with feeding and recovery length in equine colic patients after laparotomy.

This research study investigates the relationship between nutritional management and recovery length in horses that have undergone surgery for colic. Specifically, it suggests that the timing of the first feeding post-surgery impacts recovery time, with early feeding linked to shorter recovery periods.

Research Methodology

• The study employed a retrospective approach, retrieving data from the records of horses that have undergone surgery for colic at two hospitals.
• The primary outcome of interest was the recovery time post-surgery, categorized into short, medium, and long durations.
• Various parameters including patient details, preoperative clinical and laboratory examinations, postoperative parameters, as well as nutritional parameters after surgery were collected for data analysis.
• The collected data was subjected to multivariate analysis (MCA and PCoA).
• Kendall’s tau correlation was calculated to examine the association between recovery length and the other parameters. Data was also analyzed statistically for differences in the recovery length among groups (Kruskal-Wallis and Dunn’s Multiple Comparison Test).

Findings

• The researchers found no differences in preoperative clinical parameters (Body Condition Score, Packed Cell Volume, total protein), postoperative parameters (time to first defecation, time to end intravenous fluid therapy and time to first water drinking, anesthesia) and patient details (age) among the groups with different recovery lengths.
• However, the study did find differences in post-surgical nutritional parameters among these groups. Horses with a short recovery period were observed to consume a higher percentage of dry matter (DM) as forages in the 24 hours post-surgery compared to horses with longer recoveries. They also reached the minimum DM intake in a shorter period.
• Both the Kendall and MCA analysis indicated that the time to first feeding post-surgery has a positive association with the recovery length, thus suggesting that earlier feeding could lead to a shorter recovery period.

Limited Sample Size

• It is worth noting that the research was conducted with a small sample size of only 37 horses that underwent colic surgery, which may limit the generalizability of the findings.

Clinical Implications

• Despite the limited sample size, from a clinical standpoint, the study provides valuable insights into which nutritional parameters might be associated with shorter recovery periods post colic surgery in horses, particularly highlighting the potential benefits of early feeding during the recovery process.
