To compare the admission temperatures, incidence of hypothermia and discharge outcomes of preterm neonates managed with Trans-warmer mattress (TWM) initiated in the delivery room (DR) and controls.Study Design:
A prospective quasi-randomized controlled trial was performed between January and November 2009 on preterm neonates <32 weeks gestation. Infants in the intervention group were resuscitated and transported to neonatal intensive care unit (NICU) on a TWM, in addition to other measures recommended by the Neonatal Resuscitation Program.Result:
The mean (s.d.) gestational age 28.7 (3) vs 28.7 (2.4) weeks and birth weight 1151 (407) vs 1175 (413) g) were comparable in the intervention (n=53) and control (n=49) groups. Temperature of the DR, maternal temperature, 5 min Apgar score, mode of delivery, cord pH and need for resuscitation were similar in both groups. Temperature of neonates in the DR (36.3 vs 36.0 °C) was also similar. Admission temperature in the NICU was significantly higher 36.2 °C (0.8) vs 35.7 °C (0.8) and incidence of hypothermia (temperatures <36 °C) lower in the intervention group (34 vs 57%, P<0.05). TWM use was not associated with any adverse effects. On logistic regression, low birth weight, lack of use of TWM and low DR temperature were independently associated with admission hypothermia.Conclusion:
In this quasi-randomized controlled trial, the admission temperatures of preterm neonates on whom TWM was used were significantly higher compared to controls with a reduction in the incidence of hypothermia. A TWM initiated in the DR may be a simple efficacious method of reducing hypothermia in preterm neonates.
