This research was to find somes risk factors of mortality of 667 hospitalized premature in the Neonatology Department of The National Hospital of Pediatrics from 1/3/2008 to 7/31/2008. Results showed that the premature group with gestational age 25-28 weeks had the highest mortality (75.6 percent). Infants weight 1500 g had 4.8 times death risk higher than premature or = 2500 g (p 0.001). 100 percent premature had a severe malformation at birth were died. Malformation at birth group was 5 times death risk to compare with group without birth malformation. Premature with BE or or = -5 (p 0.001). Premature with FiO2 or = 0.37 was 16 times risk of death higher than the group with FiO2 0.37 (p 0.001). Premature with FiO2 or = 0.44 was 8.9 times risk of death higher than the group with FiO2 0.44 (p 0.001). Premature with PaCO2 or = 60 mmHg was 3.4 times risk of death higher than the group having PaCO2 60 mmHg (p 0.001). Temperature 35.5oC was 5 times risk of death higher than patient with temperature or = 35.5oC. Glucosemia or or = 7.0 mmol/l was 3.6 times risk of death higher than (p 0.001) than patient having normal glucosemia. pH or 7.0 (p 0.001). In conclusions, risk factors related with premature mortality were: gestational age 31 weeks and weight 1500 g; having birth malformation; BE -5, PaCO2 or = 60 mmHg, pH or or = 0.37; Need maximal suitable FiO2 or = 0.44, hypothermia; hypoglucosemia or hyperglucosemia.
