Influence of different position on oxygen inhalation effect for premature infants in the warm box

Abstract

Objective To explore the best position of oxygen inhalation for premature infants so as to reduce the time of oxygen inhalation .Methods Fifty premature infants who needed oxygen inhalation in the warm box were divided into the prone position group （singular） and the supine position group （dual） according to the order of sequence .The transcutaneous oxygen/carbon dioxide pressure （ TcPaO2/TcPaCO2 ） and HR were monitored by transcutaneous oxygen/carbon dioxide partial pressure monitoring equipment and electrocardiogram monitor before and one hour after oxygen inhalation , and the transcutaneous oxygen saturation （ TcSpO2 ） were monitored before the oxygen inhalation , and the time of TcSpO 2 stabilized at 88%-93% were monitored one hour after oxygen inhalation.The changes of TcPaO2, TcPaCO2, the index of oxygenation index （PaO2/FiO2）, HR and the time of TcSpO 2 stabilized at 88%-93%were compared in two groups .Results No difference was found in the TcSpO2, TcPaO2, TcPaCO2, HR in two groups before the oxygen inhalation （P＞0.05）.The time of TcSpO2 stabilized at 88%-93%, TcPaO2, TcPaCO2, HR and PaO2/FiO2 were （92.3 ±177;3.2）min, （65.2 ±177; 11.6）mmHg, （36.7 ±177;4.2）mmHg, （120 ±177;9）beats/min, （179.3 ±177;10.4） one hour after oxygen inhalation in the prone position group, and were respectively （97.3 ±177;5.5） min, （55.5 ±177;9.7） mmHg, （33.1 ±177;3.5） mmHg, （132 ±177;10） beats/min, （ 170.5 ±177;9.5 ） in the supine position group , and the differences were statistically significant （t=3.77, 3.01, 3.88, 4.40, 3.18, respectively;P＜0.01）.Conclusions Prone position of oxygen inhalation can significantly improve the oxygenation state of premature infants so as to stop oxygen inhalation as soon as early .
