Alterations in state in apneic pre-term infants receiving theophylline
Insights
Aminophylline treatment significantly reduced apnea in premature infants. This intervention also increased infant wakefulness and active REM sleep, potentially improving breathing control.
Area of Science:
- Neonatal Medicine
- Pediatric Pulmonology
- Sleep Medicine
Background:
- Apnea of prematurity is a common concern in neonatal intensive care.
- Effective treatments for apnea of prematurity are crucial for infant health.
- Theophylline derivatives are often used to manage neonatal apnea.
Purpose of the Study:
- To evaluate the efficacy of aminophylline in treating apnea in premature infants.
- To assess the impact of aminophylline on sleep patterns in preterm neonates.
- To explore the relationship between sleep state alterations and apnea reduction.
Main Methods:
- A cohort of 9 premature infants with apnea was treated with aminophylline.
- Serum theophylline levels were monitored, targeting a range of 2 to 10 microgram/ml.
- Apneic episodes, wakefulness, and active (REM) sleep were assessed before and during treatment.
Main Results:
- All 9 infants showed a significant reduction in apneic episodes.
- Treatment was associated with increased infant wakefulness.
- Active (REM) sleep duration also increased following aminophylline administration.
Conclusions:
- Aminophylline is effective in decreasing apnea frequency in premature infants.
- Theophylline therapy may positively alter sleep states in preterm neonates.
- Changes in sleep architecture could contribute to the reduction of apneic episodes.
Abstract:
The present study is a report on 9 premature infants treated with aminophylline for relief of apnea. With serum theophylline levels of 2 to 10 microgram/ml, all infants experienced significant decrease of apneic episodes in association with increased wakefulness and increased amounts of active (REM) sleep. These effects may occur independently, but it is possible that the alteration of sleep states may be partially responsible for the decrease in apneic episodes in these infants.
