The effects of risk factors on the improvement of hypothermia neonatal using fuzzy transition

Abstract

Background and aim: Neonatal hypothermia is a major risk factor for mortality after delivery. This study aims to identify the risk factors associated with transition in hypothermia state with new definition of hypothermia states.Methods: Four hundred and seventy nine (479) neonates hospitalized in NICU of Valiasr in Tehran, Iran in 2005 participated in this study. The rectal temperature of neonatal was measured immediately after delivery and every 30 min afterwards, until neonates became normal.Results: The mean weight of neonatal was 2580±882.9 g and mean of delivery room temperature was 29.2±1.45 °C. Most of the neonatal were mild hypothermia. There were significant associations between weight of neonatal, cardiopulmonary resuscitation (CPR) and Apgar score with hypothermia state (P<0.05). Death of neonatal was related to hypothermia state.Conclusion: The findings of this study indicated that a major risk factor for hypothermia was low weight of neonatal.
