Polyethylene wrap for thermoregulation in the preterm infant: a randomized trial.

Area of Science:

• Neonatal care
• Thermoregulation in infants
• Pediatric critical care

Background:

• Maintaining normothermia is crucial for preterm infant outcomes.
• Traditional methods of temperature management can be less effective.
• Exploring innovative methods for neonatal temperature control is essential.

Purpose of the Study:

• To compare the effectiveness of polyethylene wraps versus a sterile preheated field for temperature adaptation in preterm infants.
• To evaluate the impact of drying before polyethylene wrap application on infant temperature.
• To assess both axillary and incubator temperatures over time.

Main Methods:

• A comparative study involving preterm infants.
• Intervention groups: polyethylene wrap (with/without drying) and sterile preheated field.
• Temperature monitoring: axillary and incubator temperatures recorded at specific intervals.

Main Results:

• Both polyethylene wrap methods achieved a mean axillary temperature of 36.5°C at 30 minutes, significantly faster than traditional care (75 minutes).
• Incubator temperatures at 120 minutes were highest in the preheated field group (35.15°C) compared to polyethylene wrap groups (34.20°C).
• No significant difference in axillary or incubator temperatures was observed between the polyethylene wrap groups (with or without drying).

Conclusions:

• Polyethylene wraps are effective in achieving rapid temperature normalization in preterm infants.
• A sterile preheated field provides better sustained incubator warming compared to polyethylene wraps.
• Drying before applying a polyethylene wrap does not appear to influence temperature maintenance.
