The Effect of Endotracheal Suctioning Using the Four-handed Care on Physiological Criteria and Behavioral Responses of the Preterm Infants: Randomized Crossover Clinical Trial.

Endotracheal suctioning, despite its necessity, is one of the procedures that can cause pain and stress for infants admitted to neonatal intensive care units. Pain and stress manifest with physiological and behavioral responses in infants. This study is a cross-sectional clinical trial that aimed to investigate the effect of endotracheal suctioning using four-handed care on the physiological criteria and behavioral responses of preterm infants. In this study, 40 infants were randomly divided into two groups of 20, one group was first suctioned by the routine method (two hands) and then with the four-handed method. The other group was first suctioned by the four-handed method and then with the routine one. The ALPS NEO was used to evaluate behavioral criteria. One camera recorded facial expressions and body movements, and physiological data were recorded from the monitor simultaneously. Four-handed suctioning method can prevent an increase in heart rate during and two minutes after suctioning but it did not affect behavioral responses and oxygen saturation of the preterm infants admitted to NICUs. Since one of the symptoms of pain and stress in infants is the change of vital signs, especially the heart rate, stable heart rate during painful procedures can be an indication of the effectiveness of the four-hand method in invasive procedures such as suctioning. Implications for Practice: We recommend four-handed method for suctioning of endotracheal tube. Implications for Research: Evaluate the effect of four-handed care by mother on physiological criteria and behavioral responses of the preterm infants.
