Abstract
OBJECTIVES: To document whether medically stable infants can be transferred safely from incubators to unheated, open cots at 1500 g. METHODS: Four cohorts were recruited in a stepwise observational trial of transfer from incubators to unheated, open cots. We aimed to transfer the first 15 infants into cots on reaching a weight of 1800 g, the second at 1700 g, the third at 1600 g and the fourth at 1500 g. Nursery temperatures were set at 25 degrees C. The primary outcome measure was failure of transfer defined as the inability to maintain body temperatures in a cot despite additional coverings, with two consecutive axillary temperatures below 36.6 degrees C 1 h apart. Secondary aims were to determine temperature stability, growth, medical complications and time to discharge for these infants. Weight and corrected gestation at discharge were recorded. RESULTS: A total of 61 infants were recruited and transferred into cots. Cohorts were similar in gestation and sex. Infants recruited to the 1500 g cohort had higher birthweights than the other cohorts. There was no difference in the rate of infants failing transfer into cots between cohorts. Rate of weight gain before and after transfer and the number of high and low temperatures per infant after transfer was not different between cohorts. There were no differences between cohorts for discharge weight or corrected gestation. CONCLUSIONS: The results of this pilot study indicate the potential to transfer very low birthweight infants to an open unheated cot at a bodyweight of 1500 g. This study provides information for the design of future randomized controlled trials that are required to confirm the findings of this study before routine adoption of this intervention into clinical practice.
