Effect of two polyethylene covers in prevention of hypothermia among premature neonates

Abstract

Abstract

Background: After the umbilical cord is cut, premature neonates face numerous problems including hypothermia. With regard to serious complications of hypothermia and incapability of conventional methods in preservation of neonates’ temperature after admission, the researcher decided to conduct a study on the effects of two polyethylene covers in prevention of hypothermia among premature neonates.

Materials and Methods: This clinical trial was conducted on 96 neonates aged 28–32 weeks that randomly allocated, by drawing of lots, to three 32‑subject groups as follows: Intervention group 1 (a plastic bag cover and a cotton hat), intervention group 2 (a plastic bag cover and a plastic hat), and a control group receiving routine care. Data were analyzed by descriptive and inferential statistics through SPSS V.14.

Results: Mean axillary temperatures in intervention groups 1 and 2 were different after admission and 1 and 2 h later, but this difference was not significant and the mean axillary temperature increased with time. Mean axillary temperature in the control group showed no significant difference at these time points and it did not increase with time. The mean temperatures in preterm infants were significantly higher in the intervention groups after admission and 1 and 2 h after birth, compared to the control group. Mean axillary temperature in intervention group 2 was significantly higher than in intervention group 1.

Conclusions: Usage of a plastic bag cover and a plastic hat (with no risk of hyperthermia) is more effective in preventing hypothermia among neonates aged 28–32 weeks, compared to usage of a plastic bag cover and a cotton hat.
