The Effects of Open Endotracheal Suctioning(ETS) and Close ETS on Oxygen Saturation and Heart Rate in Premature Infants with Respiratory Distress Syndrome

개방형과 폐쇄형 기관지 흡인술이 호흡곤란 미숙아의 산소포화도와 심박동수에 미치는 영향에 대한 비교연구

Prematurity is the main cause for respiratory distress syndrome (RDS) in neonates. The goal in the treatment of RDS is to maintain respiration with adequate oxygenation. ETS needs to be performed to remove lung secretions in the ventilated premature infants with RDS. Oxygen saturation(SpO$_2$) and heart rate(HR) were compared in 22 premature infants with RDS using two types of ETS : open ETS versus close ETS. The results showed there was no significant difference in the SpO$_2$ and HR responses between open ETS and close ETS. The SpO$_2$ and HR returned to the baseline within 1 minute after suctioning. But in some case, there was a significantly greater incidence in the decrease of SpO$_2$ below 90% occured in the open ETS than in the close ETS. It implies that closed ETS may be beneficial to the premature infants who tend to develop desaturation easily.
