Early intragastric feeding of seriously burned and long-term ventilated patients: a review of 55 patients.

Aims of this retrospective study were: (1) to evaluate the feasibility of a protocol for early intragastric feeding: (2) to examine whether the caloric needs can be provided via the intragastric route within 72 h postburn; (3) to determine the influence of a delayed onset of feeding on the success of the feeding protocol; (4) to evaluate whether delayed feeding has any impact on morbidity and mortality. Fifty-five long-term ventilated patients were enrolled in the study. Their mean age was 37.6 years and mean total body surface area burned 44.2 per cent. The mean duration of ventilation amounted to 24.8 days. Intragastric tube feeding was initiated as early as possible after admission. Forty-five patients (81.8 per cent) could be fed successfully and their caloric needs were met within 72 h. In these patients the mean interval between burn injury and the initiation of tube feeding was 11.5 h. The mean interval was 32.4 h in the 10 patients, demonstrating failure of early intragastric feeding. Only four of the 48 patients who had enteral feeding within 18 h postburn failed to meet the caloric needs. The patients fed successfully showed a significantly decreased mortality. Early intragastric feeding after serious burns can be initiated successfully. A time interval of more than 18 h is unfavourable and significantly decreases the success rate.
