The effect of posture on oxygenation, vital signs and duration of weaning during wean off mechanical ventilator in preterm infants
Abstract:
The purpose of this quasi-experimental research was to compare the effects of
side lying and regular positions on oxygen saturation, heart rate, respiratory rate and
duration of weaning in preterm infants during weaning off mechanical ventilator. The
sample was 46 preterm infants (23 infants in the control group and 23 infants in the
experimental group) who had been admitted in Neonatal Intensive Care Unit (NICU)
Phranakornsri Ayutthaya Hospital and were selected according to the inclusion
criteria. Data of control group were obtained from retrospective chart review and the
data of experimental group were collected by posing the infant in the side lying
position from April to November 2006. Statistical analyses used were T-test
independent and repeated measure of ANOVA
The results revealed that the mean oxygen saturation and heart rate of preterm
infants with side lying position was not significantly different from the regular
position during weaning off mechanical ventilator (p > .05). Mean respiratory rate of
the preterm infants with side lying position was significantly higher than regular
position (p < .05) and duration of weaning in the preterm infants with side lying
position was significantly shorter than regular position (p < .05). However, the preterm
infants with side lying position had more stabilized oxygen saturation and heart rate
than those in the regular position.
These findings suggest that nurses in the NICU should put preterm infants in
side lying position during weaning off mechanical ventilator for stabilized oxygen
saturation, heart rate and decreased duration of weaning off mechanical ventilator.
