Efficacy of comprehensive warming intervention strategy on gestational age <32 weeks preterm infants' body temperature during inter-hospital transportation / 中国新生儿科杂志

ABSTRACT

Objective:To study the effects of comprehensive warming intervention strategy on the body temperature of preterm infants (gestational age <32 weeks and birth weight <1 500 g) during inter-hospital transportation.Method:From October 2016 to July 2019, eligible preterm infants transported to our hospital were retrospectively analyzed. From October 2016 to March 2018, preterm infants transported with routine transportation strategy were assigned into the control group. From April 2018 to July 2019, preterm infants transported with the comprehensive warming intervention strategy were assigned into the experiment group. The body temperature, complications and prognosis before and after the transportation to our NICU were compared.Result:A total of 1 194 premature infants with gestational age <32 weeks were included with 630 cases in the control group and 564 cases in the experiment group. No significant differences existed in demographic data of the mothers, infants and the transportation time between the two groups ( P>0.05). The body temperatures before and after transportation in the experimental group were (36.8±0.5)℃ and (36.7±0.5)℃, significantly higher than the control group [(36.0±0.4)℃ and (36.3±0.6)℃] ( P<0.01). The incidences of hypoglycemia and mortality in the experimental group were 3.7% (21/564) and 4.8% (27/564), significantly lower than the control group [8.4% (53/630) and 7.9% (50/630)] ( P<0.05). Conclusion:Comprehensive warming intervention strategy in inter-hospital transport can effectively improve the body temperature of preterm infants before and after transportation, reducing the incidences of hypoglycemia and mortality.
