Stress ulcers in intensive care (etiology, symptomatology and therapy)

The authors present a group of 48 patients with stress ulcers (36 men, 13 women) average age 56.2 years. The analysis of the cases allowed to establish, for the first time in medical literature, a correlation between the etiology, the symptomatology and the moment of onset of the haemorrhage, with important practical implications in the adoption of a treatment regime. These considerations permitted us to delineate four categories of stress ulcers: The first category included stress ulcers caused by a cerebral lesion and manifested through cerebral hypertension. The upper digestive haemorrhage occurred within 24-48 h after the aggression and required the correction of the cerebral hypertension and of the anaemia. The second category comprised stress ulcers brought about by a hypovolaemic shock through myocardial infarction, burns, frost-bite and multiple traumas. Haemorrhage in the upper digestive tract appeared within 3-6 days after the moment of aggression and required surgical control unless it was caused by myocardial infarction. The third category was represented by post-operative stress ulcers. These forms occurred usually late, between the eighth and the thirty-seventh day after the aggression, and were due to the super-imposition of the septicaemia on the post-aggressive systemic reaction. The chief aim of treatment here was the surgical control of infection. The fourth category encompassed the stress ulcers occurring after protracted coma, especially in patients with ventilatory assistance. In these conditions, the ulcers of the digestive tract and the consequent haemorrhage represented terminal elements of irreversible diseases, in which no treatment was effective.
