Behaviors of preterm infants with and without chronic lung disease when alone and when with nurses
Insights
Preterm infants with chronic lung disease do not show increased irritability or negative reactions to care compared to their peers. This study found minimal behavioral differences between the two groups of infants during observation periods.
Area of Science:
- Neonatal care
- Pediatric respiratory health
- Infant development
Background:
- Clinicians often perceive infants with chronic lung disease as more irritable.
- This perception may influence caregiving practices and expectations.
- Objective data are needed to validate these clinical observations.
Purpose of the Study:
- To compare sleep-wake states and behaviors of preterm infants with and without chronic lung disease.
- To investigate if behavioral differences are more pronounced during nursing interactions.
- To provide evidence regarding the irritability and care-related responses in infants with chronic lung disease.
Main Methods:
- Observational study comparing 31 high-risk preterm infants without chronic lung disease and 20 with chronic lung disease.
- Observations conducted in intermediate care settings between 32 and 36 weeks postconceptional age.
- Separate analyses for infant-alone periods and periods with nurses present.
Main Results:
- No significant differences in sleep-wake states were observed between the groups.
- Infants with chronic lung disease showed more jitters, but only when alone.
- Limited behavioral differences were noted, with fewer differences occurring when nurses were present.
Conclusions:
- There is no evidence to support the belief that preterm infants with chronic lung disease are more irritable.
- Infants with chronic lung disease do not react more negatively to care compared to other preterm infants.
- Behavioral observations do not corroborate common clinical assumptions about irritability in this population.
Abstract:
Many clinicians believe that infants with chronic lung disease display more irritability and react more negatively to care than other preterm infants. Therefore, the sleep-wake states and behaviors displayed by 31 high-risk preterm infants without chronic lung disease and 20 infants with chronic lung disease during four-hour observations conducted in intermediate care between 32 and 36 weeks postconceptional age were compared. Separate analyses were conducted for times when infants were alone and when they were with nurses to determine whether behavioral differences might be greater during handling. There were very few differences between the groups in either situation. Sleep-wake states did not differ. The infants with chronic lung disease exhibited more jitters at every age, but only when they were alone. Infants with and without chronic lung disease showed isolated differences in five behaviors when they were alone but in only two behaviors when they were with nurses. Thus, there is no evidence that 32- to 36-week preterm infants with chronic lung disease are more irritable or react more negatively to care than other preterm infants.
