Randomized Evaluation of the Use of Plastic Bags to Prevent Neonatal Hypothermia in Developing Countries-Part IV

Due to limited resources and numbers of incubators, hospitals in developing countries remove infants from incubators at lower weights than in developed countries, putting infants at increased risk for hypothermia. This study will compare the incidence of hypothermia during the 72 hours after incubator removal of infants randomized to receive standard incubator removal (control group) or standard incubator removal with a plastic bag covering their torsos and lower extremities (intervention group). The axillary temperature of each infant will be taken upon removal from the incubator, every subsequent 6-8 hours, and finally, at 72 hours as the bags are removed. Blood pressure, blood sugar, seizures, weight gain, hyperthermia, death, observation for respiratory distress, bronchopulmonary dysplasia, sepsis, intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, intestinal perforation, pulmonary hemorrhage room temperature and humidity, and length of time in an incubator will be recorded throughout their hospitalization for all infants. With an estimated hypothermia incidence of 30% and a hypothesized 20% absolute risk reduction (66% relative risk reduction), a sample size of 118 will be used to have a power of 80% and a confidence interval of 95%.
