Low-Cost and Reusable Thermal Jacket for Managing Preterm or Low Birth Weight Neonates.

We will equip a single arm trial with no control group design, in which every enrolled neonate will get the experimental therapy (thermal jacket) for this phase. A thermal jacket trial on a preterm or LBW neonate will be considered an event. An event will be considered a success if the neonate can maintain the body temperature in the euthermic range (36.5°C-37.5°C) using the thermal jacket for two hours. Thus, the failure event will be if the thermal jacket fails to maintain euthermia for neonates for two hours. Suppose, the neonate's body temperature drops below 36.5°C or rises above 37.5°C, the neonate will be monitored for maximum 5 minutes. If not recovered from the state, the neonate then immediately will be removed from the event for the appropriate management under the study's responsibility.
