Comparison of Prone and Supine Positions on Oxygenation of Nasal CPAP Treating Premature Infants with Respiratory Distress Syndrome in Tabriz Al –Zahra Hospital, 2010.

Abstract

Abstract: Introduction: One of the most common ways for treating respiratory distress syndrome in preterm infants is to use Continuous Positive Airway Pressure (CPAP). The general belief during premature infants' treatment is to reduce pressure and concentration of O2 as soon as possible. One of the factors which has important role in improving infants' respiratory promoting oxygenation. Considering that there has not been found any clear study about the effect of this positioning type on oxygenation of N-CPAP treating premature infants, this study aims at comparing supine and prone positions on oxygenation of N-CPAP treating premature infants with respiratory distress syndrome. Method: This experimental before/after study has been done with the crossover method in 1389 over 44, 29-34 weeks gestation premature infants, which were under N-CPAP treatment in NICU ward in Tabriz Al –Zahra hospital. Infants were randomly divided into 2 groups. The positioning of first group was at first prone and then supine and the positioning of second group was vice versa. Sat O2, RR and HR were assessed three times (every 10 minutes) for 30 minutes totally in each position. Personal data and oxygenation parameters were recorded in a data collection from and the data was analyzed using SPSS, 17, paired t test and repeated measurements. Results: T test outcomes showed that there is a significant statistical difference in SatO2, FiO2, RR and HR in both groups in each position (p<0.05). Comparing groups' parameters, the results of variance test were meaningful as well (p=0.00). Discussion and Conclusion: This study suggest that in prone position rather than supine, sat O2 of infants under N-CPAP treatment is increased and following that, the need for Fi O2 is decreased. In addition, infants, RR and HR were decreased in prone position as compared with supine. Achieved outcomes supports research's hypothesis. Therefore, it is suggested that if is not any obstacle for changing the infants' position, prone position can be used for improving oxygenation and fast reducing of O2 concentration while treating with N-CPAP.
