Intra-abdominal Pressure Screening of Horses With Colic.

The research article evaluates the relation between intra-abdominal pressure (IAP) and various colic-related conditions in horses. The primary findings suggest that higher IAP is linked to severe forms of colic that require surgical intervention and have a higher risk of death or euthanasia.

Study Overview

• The research was a 2-year cohort study, conducted between 2014 to 2016, in a veterinary teaching hospital.
• The subjects were 28 horses of different breeds and both genders, aged between 2 and 20 years, and weighing between 300 and 450 kg.
• All these horses were demonstrating signs of colic, a condition in horses characterized by abdominal pain.

Methodology

• IAP, which indicates the pressure within the abdominal cavity, was measured in two ways: at the right flank when the horse was standing under sedation, and at the linea alba when the horse was in a supine position under general anesthesia.
• Each measurement site had twenty readings taken at the point of end expiration.

Findings and Conclusions

• IAP values greater than 0.0 mmHg, obtained while measuring at the upper right flank in the standing position, were linked with surgical treatments.
• These higher IAP readings were associated with strangulated obstructions of the large colon, resulting in a significant increase in death occurrences due to colic.
• The research also discovered that IAP could vary considerably within horses suffering from colic, even if the underlying causes were the same.
• The study indicates that horses with colic related to strangulating obstructions of the large intestine and an IAP greater than 0.0 mmHg at the upper right flank were more likely to require surgery and face death or euthanasia.

The outcomes of this research shed light on the need for a more detailed understanding of the relationship between IAP and different manifestations of colic in horses. Such insight might guide veterinarians in determining the best course of action when treating horses with colic.
