Lactate concentrations in dialysate and plasma in colic and healthy horses. The mean (± SEM) lactate concentrations in gluteal muscle dialysate and plasma in 8 colic horses (a) and in 10 healthy horses (b) during anaesthesia, in response to regaining the standing position (time 0) and up to 24 h after standing. Due to loss of the microdialysis catheter the number of dialysate samples decreases with time. At 10 h after standing there are results from 8 colic and from 5 healthy horses, and at 20 h after standing there are results from five colic horses but from no healthy horse.
