Insights
Containment, or restraining an infant's movements, significantly impacts premature infants' post-suctioning oxygen levels. This study found that this intervention affects transcutaneous PO2 values in neonates with respiratory distress syndrome.
Area of Science:
- Neonatal Medicine
- Pediatric Respiratory Care
- Infant Physiology
Background:
- Premature infants with respiratory distress syndrome require airway suctioning to clear lung secretions.
- Suctioning can lead to adverse physiological responses in neonates, including hypoxemia.
- Previous research has explored various infant responses to suctioning but often in isolation.
Purpose of the Study:
- To investigate the effect of infant movement containment during suctioning on premature infants.
- To determine if containment influences postsuctioning transcutaneous oxygen levels (PO2) in neonates.
Main Methods:
- A study involving 24 premature infants (24-33 weeks gestational age) with respiratory distress syndrome.
- Suctioning and containment procedures were performed by the same nurse in a neonatal intensive care unit.
- Statistical analyses, including Student's t-tests and ANOVA, were used to evaluate the technique's effect.
Main Results:
- Infants receiving containment showed significantly different postsuctioning transcutaneous PO2 values compared to those without containment.
- The study identified a measurable impact of the containment technique on oxygenation levels.
Conclusions:
- Containment is a viable intervention to modify physiological responses to suctioning in premature infants.
- This technique may help stabilize or improve oxygenation in vulnerable neonates undergoing airway clearance.
Abstract:
The purpose of this research was to examine the effects of containment (restraint of an infant's movements) on premature infants' postsuctioning transcutaneous PO2 values. The hypothesis was that premature infants receiving containment would have significantly different postsuctioning transcutaneous PO2 levels than infants receiving no containment. Premature infants with respiratory disease require suctioning to remove excess secretions from their lungs. Research studies document a variety of infant responses to suctioning; hypoxia, hypoxemia, increased blood pressure, bradycardia, increased intracranial pressure, and increased cerebral blood flow velocity. Most studies have examined only a few isolated variables and the magnitude and duration of hypoxemia in response to suctioning. Our sample comprised 24 infants less than 72 hours of age, who had respiratory distress syndrome and had been born at between 24 and 33 weeks' gestational age. The setting was a neonatal intensive care unit of a large county hospital. The same nurse performed the suctioning and containment procedures in all subjects. Student's t-tests and analysis of variance were carried out to determine the effect of the technique.
