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.
