Abstract

Objective: to determine the survival of children with low weight at birth hospitalized in the neonatal intensive care unit of a hospital of third level of complexity in the city of Medellín, between 1997 and 2001, with the purpose of identifying some characteristics related to the probability of dying and the time of survival of the newborn. Methodology: information concerning the objective was gathered on the basis of a population of 809 newborns. To estimate the survival the pertinent charts of life were built and to value its significance with regard to variables of interest, the Kaplan Meier method, the log rank test, and the Cox proportional hazards model were used. Results: 50% of the 809 newborns entered to the service in less than 24 hours after birth, reaching a stay for an average of 7.8 days, time during which the hyaline membrane illness occurred to 76% of them. The accumulated survival probability diminished gradually by 50% in the first 28 days of hospitalization; the descent was slower after day 29; it is worthy of notice that 59.7% of the deaths occurred before the first 7 days of hospitalization. During hospitalization, 51.5% of the children with excessive low weight at birth died. This fact implied a descent of 33% in the survival accumulated in the first 4 days of hospitalization.
