Abstract

Objective. To determine factors of risk of Hyperblirrubinemia Neonataly non hemolítica in newly born to term, in the department of Neonatology of the Hospital Vicente Corral Moscoso, 2009.

The data were obtained of clinical histories and in the analysis odds ratio(OR was calculated) with interval of trust (IC) of 95%.

Results. The associate factors significantly with hyperbilirrubinemia they were: it suffocates with OR 9.09, IC 95% (3.77 – 22.58) p=0.01; RPM> 15 hours with OR 6.20, IC95% (3.33 – 11.60) p=0.01; fast OR 6.00, IC95% (3.11 – 11.64) p=0.01 and maternal age OR 1.48, IC95% (1.07 – 2.05) y p= 0.01 The factors associated of non significant way are toxemia, Caesarean operation.
