Basal plasma cortisol concentrations in 25 dogs with non-adrenal illness were two to three times higher than in 25 normal dogs (158 ± 25 nmol litre-1 compared with 65 ± 22; mean ± sd). In addition, plasma cortisol concentrations were measured in 12 animals undergoing major abdominal, thoracic or orthopaedic surgery and compared to a group of six anaesthetised dogs. Anaesthesia alone failed to significantly alter plasma cortisol levels, however, all forms of surgery produced a significant increase in plasma cortisol concentration which returned to normal 24 hours after completion of surgery.
