| Research Abstract |
This study aimed to clarify the effect of "flexed prone posture with boundaries" on infants after the treatment of endotracheal aspiration through observation of behavioral condition and comparison with the effects of a routine care. The cases comprised nine extremely low birth weight infants, whose average intrauterine age had been 26.3 weeks (from 25 weeks and 1 day to 28 weeks and 1 day) and average body weight at birth had been 811.8 g (from 648 g to 1,104 g). The infants, whose parents had agreed to their participation in this study, were randomly allocated into two groups of interposition (n = 4) and control (n = 5) by an envelope method. Each case in the two groups was observed and analyzed at every 2 minutes, from before the aspiration to 30 minutes after the aspiration, based on the following three indices : functioning of the autonomic system that was estimated by the measurement of heart rate and oxygen saturation, the stress sign that was collectively estimated from the par

ameters of motoric system obtained by the observation of behavior, and the dormant condition that was estimated according to the Thoman classification. The validity of the behavioral parameters, the reliability of the measurement, and the comparability of the interposition had been ensured before the collection of the data. Furthermore, an application form of ethical review concerned with this study had been accepted by both the ethical review board and the clinical trial judging committee.
The results revealed that there was no difference between the counts of stress sign from "flexed prone posture with boundaries" and those from routine care. However, the counts of stress sign at 1 min after the interposition were less than the reference, and the low counts, such as 1-1.5, were maintained subsequently.
The estimation of transitional stress sign and behavioral condition of a larger number of cases than those included in this study should be performed, since it is affected by the severity and the maturation of the cases. Less
