The overall hypothesis is that plastic bags used in combination with WHO thermoregulation care will reduce the incidence of hypothermia in preterm/low birth weight and full term infants when compared to routine WHO thermoregulation care alone. Part V is comparing use of a plastic torso wrap to no plastic torso wrap in preterm/low birth weight infants following removal from their incubator to assist with temperature regulation.
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%.

| Hypothermia prevention with plastic bag | Procedure | Upon removal from the incubator, infant will be placed into a plastic bag to his/her axillae, and the bag will be folded and taped to itself to prevent it from covering the infant's nose or mouth. The infant will be wrapped in a blanket and receive a cloth hat. The bag will be changed when soiled and the infant will remain in the bag for 72 hours or until discharge, whichever comes first. The infant's temperature will be monitored for 72 hours or until discharge, whichever comes first. |
| Measure | Description | Time Frame |
|---|---|---|
| Axillary temperature 36.5-37.5 degrees Celsius | Temperature taken per axilla for one minute | 1-72 hours |
| Measure | Description | Time Frame |
|---|---|---|
| Blood pressure | Measure of extremity blood pressure per cuff taken during nursery stay | Up to 4 weeks |
| Blood glucose | Measure of blood glucose per laboratory value taken per heel stick |
