Development of a technique to directly measure arterial blood pressures in horses after anesthesia and surgery for exploratory laparotomy due to colic

Hypotension (low blood pressure) is a common occurrence in equine anesthesia. It can occur in any of equine patient, even those who are healthy and undergoing anesthesia for an elective procedure. It is more common in horses undergoing emergency surgery (ex: colic surgery.) Blood pressure in horses is most accurately measured by placing a catheter in an artery. This type of catheter is placed in all horses undergoing general anesthesia at the OSU VMC. In most cases, these catheters are removed before the horse is moved to the recovery stall. In this study, the catheter will be left in place during recovery, and blood pressure will be monitored and recorded. This will help to describe post-operative blood pressure in horses undergoing colic surgery.

Which patients are eligible to participate in this clinical trial?
All horses undergoing emergency surgery for abdominal exploration (colic surgery).

What side effects or risks may my dog experience while participating in this clinical
trial?
The biggest risk of leaving an arterial catheter intact during recovery is that the catheter may become dislodged while the horse is attempting to stand. This may result in some mild bleeding, bruising or swelling at the catheter site; these should resolve within 2-3 days.

What financial incentives will be provided for my horse’s participation?
Unfortunately, no financial incentive is available at this time.
