Assessment and comparison of microcirculation and macrocirculation in horses undergoing emergency exploratory celiotomy versus elective surgical procedures.

Objective: To assess oral buccal microcirculation by hand-held videomicroscopy in horses during colic surgery, comparing microcirculation values with macrocirculatory parameters and with those of healthy elective surgical horses.

Study Design: Clinical prospective study.

Animals: Client-owned horses (nine in the colic group; 11 in the elective group).

Prevalence of intra-abdominal hypertension in horses with colic.

Objective: To determine an abdominal pressure cutoff value for intra-abdominal hypertension (IAH) in the horse and characterize IAH in horses with acute colic.

Design: Prospective clinical cohort.

Setting: University teaching hospital.
