Abstract
This paper highlights the difficulties of diagnosing intestinal ischaemia in unconscious patients on an intensive care unit. We have analysed the clinical details and investigations of eight such patients in whom a preoperative diagnosis of intestinal ischaemia was made on clinical grounds. Intestinal ischaemia was confirmed at laparotomy in only four cases (50%). These patients showed no significant differences in any of the commonly accepted parameters of intestinal ischaemia from the four patients who had a negative laparotomy. In particular, all patients exhibited a metabolic acidosis with fever and a leucocytosis. There was a mean delay of 13.6 h between surgical opinion and laparotomy in the four patients with ischaemia, only one of whom was salvaged. There was no morbidity associated with the laparotomy in this small series. It is suggested that, in the intensive care setting, early laparotomy should be performed immediately the clinical suspicion of intestinal ischaemia arises.
