CANCELA, MARÍA JOSÉ et al. Strategies for diminishing morbidity and mortality in newborn with birth weight less than 1 000 g in public health centers (Pereira Rosell Hospitalary Center, Neonathology Unit). Rev. chil. pediatr. [online]. 2007, vol.78, n.4, pp. 430-436. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41062007000400015.

Newborns weighing less than 1000 g represent approximately 1% of births at Centro Hospitalario Pereira Rossell (CHPR) over the five years. Despite this low rate, contributes in a high percentage to perinatal mortality. The objetive is to show the tendency observed after 5 month-application of a lower than 1.000 g attendance protocol according to our sanity facilities. To minimize mortality and morbidity at this group, a 3 stage strategy is designed: 1) Know the reality, identifying the most relevant prognostic factors in the year 2002. 2) Perform a management protocol to modify these findings. 3) Evaluate the results after the application of this protocol in the year 2004. The population analyzed include the total number of preterm newborns weighing less than 1000 gr who were born al CHPR and were admitted into this center during the whole studied period. Material and Methods: Review of clinical records, elaboration of an attendance protocol and prospective evaluation of obstetric an neonatal attendance results after its implementation. Among these, it stands out a better obstetric management, which is seen in the increasing use of prenatal corticosteroids from 26,5% in 2002 to 40,% in 2004, obtaining newborns with umbilical cord blood samples without acidosis in de 94% the newborns. In 2004 improves the survival rate to 100% from 27 weeks of gestation and 65% of the newborns weighing more than 750 gr compared to 39% in 2002
