Study of the clinical effects of postoperative parenteral nutrition in 15 horses.

This research investigates the clinical effects of providing parenteral nutrition to horses after they’ve undergone surgery for a strangulated small intestine. The study found that while parenteral nutrition may have some short-term negative impacts, there were no significant detrimental effects observed and no signs of overall improvement in the horse’s health status.

Study Design and Methodology

• The study was designed as a comparative research where two groups of 15 horses each, all recovering from a similar surgery – resection and anastomosis of a strangulated small intestine, were observed.
• The researchers separated the two groups based on their post-surgery feeding approach. One group was given parenteral nutrition, a method of feeding that bypasses the digestive system and introduces nutrients directly to the bloodstream. The other group was starved as per routine post-surgery procedure.

Findings and Observations

• The study provided some evidence that parenteral nutrition might have a temporary negative effect on the catheter sites and the process of gastric emptying. Catheter sites are the points where the feeding tube is inserted, and may be sensitive or prone to infection. Gastric emptying is the process of food passing from the stomach into the small intestine, and disturbance in this process can result in discomfort or other gastric complications.
• Notably, the negative impacts mentioned were short-lived and didn’t translate into severe clinical consequences. The outcomes did not cause lasting harm to the horses.
• Contrary to what one might expect, feeding the horses directly through their bloodstream after the operation did not seem to improve their condition. There was no observational evidence suggesting an enhancement in their health status compared to those who were starved.

Conclusion and Implications

• The research concludes that parenteral nutrition, while having some minor temporary drawbacks, does not bring about significant clinical harm to horses recovering from a resection and anastomosis.
• However, surprisingly, it did not offer any noticeable benefits to the horses’ condition either, raising questions about the effectiveness of this feeding method for postoperative care in horses.
• Larger scale studies might be useful to further understand these findings and determine whether parenteral nutrition should be regularly used for horses in this condition, or whether alternative feeding strategies might yield better results.
