Measurements of blood gases and respiratory rate were made in 63 surgical patients during consciousness and sleep. Sleep-induced hypoventilation results in significant alteration of arterial PO2 and PCO2. The therapeutic possibilities to avoid critical postoperative hypoxaemia are intermittent positive pressure ventilation, mobilisation of the patient and O2 insufflation.

Of 3558 patients in intensive care, 1093 developed acute respiratory insufficiency. 3.5% and 10% respectively developed radiological changes characteristic of so-called shock lung. It was possible to identify characteristic radiological changes occurring in stages, which made it possible to define four separate phases.
In our intensive care unit we were able to prevent almost all bleedings from stress ulcerations in patients with insufficiency of various organs (1,6%) by administering the H2-receptor blocker cimetidine in doses of 8 X 200 mg per day. However, stress ulcer bleedings occurred in 14% of those patients also suffering from a sepsis. At lower doses of cimetidine, the rate of bleeding was comparable to that encountered in patients treated with antacids, i.e. 12,5% patients with multiple organ insufficiency and 42,7% with sepsis. Cimetidine was able to stop less extensive bleedings, but did not show any therapeutic effect in case of bleeding which led to a significant fall in hemoglobin concentration.

The protective effect of Vitamin A against stress-induced ulcerations of the gastric mucosa was investigated by the hypoxic stress model of the rat. The incidence of acute mucosal erosions in the main stomach was significantly reduced by intramuscular application of 125 000 - 500 000 U Vitamin A/kg body weight prior to or immediately after the onset of stress. A dosage smaller than that or an application 2 hours after the onset of stress had no influence on the development of the acute mucosal erosions.
A significant reduction of vitamin A serum levels was observed in rats which underwent a hypoxic stress. The number of gastric ulcerations secondary to stress can be significantly reduced by 125 000 to 250 000 I. E. of vitamin A applicated parenterally prior or with the onset of stress. Consequently a prophylaxis of stress ulcerations appears to be possible by application of vitamin A.
