At the time of the query, 1174 patients. Among these, 707 (60%) received early enteral nutrition and 467 (40%) did not. At least 1 severity-of-illness score was available in each patient’s record: APACHE II in 924 records (78.7%), SAPS II in 1045 (89.0%), and MPM-0 in 1008 (85.9%). We found no difference in the lowest mean arterial pressure in the first 24 hours between the early feeding group and late feeding group.
The early feeding group significant lower severity of illness as indicated by the SAPS II and APACHE II values, but not by the MPM-0 score.
