Radiant Warmer Trial - Full Text View

Purpose

The purpose of this study is to compare three radiant warmer beds that contain different computer heating software and different bed styles. Radiant warmers are used in many neonatal intensive care units (NICU) to provide heat to infants to help regulate an infant's temperature. It is common for babies to require care on an open bed that provides heat to the baby according to the baby's needs and at the same time allows easy access to the baby for care and necessary procedures. There are different styles of beds, each with unique computer software that can guide how a bed's heater output is automatically adjusted according to a baby's temperature needs. It is unknown which style of bed or method of heating might be best. This study seeks to evaluate infant responses to three different types of radiant warmer beds.

Primary Outcome Measures:

Abdominal skin surface temperatures and axillary temperatures under 3 radiant warmer conditions as measured by skin thermistors and infrared thermography (IRT). [ Time Frame: There is a 4-hour baseline/washout period, followed by a 20-hour data collection cycle that will be repeated for all three-treatment conditions. Samples from the bed and telethermometer will be collected electronically every 60 seconds. ] [ Designated as safety issue: Yes ]
