Insights
Theophylline effectively reduces central apneas in infants, decreasing both incidence and density of prolonged breathing pauses. This treatment offers benefits beyond natural age-related improvements in infant respiratory control.
Area of Science:
- Neonatal Medicine
- Pharmacology
- Respiratory Physiology
Background:
- Infant apneas and periodic breathing are common concerns in neonatology.
- Pneumographic abnormalities indicate potential respiratory challenges in newborns.
- Understanding the efficacy of pharmacological interventions is crucial for infant care.
Purpose of the Study:
- To assess theophylline's impact on the frequency and severity of central apneas.
- To evaluate theophylline's effect on periodic breathing incidence.
- To compare theophylline's efficacy against age-related resolution of respiratory abnormalities.
Main Methods:
- A randomized controlled trial involving 96 infants with abnormal pneumograms.
- Infants were allocated to receive either theophylline or a placebo.
- A control group of 94 healthy infants was included for comparison.
Main Results:
- Theophylline significantly reduced the incidence and density of apneas (≥15 seconds).
- Theophylline treatment resulted in fewer short apneas (≥6 seconds) compared to controls.
- Both theophylline and placebo groups showed age-related reductions in periodic breathing.
Conclusions:
- Theophylline is effective in managing infant apneas, reducing both their occurrence and duration.
- The benefits of theophylline extend beyond natural maturation of breathing patterns.
- Theophylline represents a valuable therapeutic option for infants experiencing significant apneas.
Abstract:
To evaluate the effectiveness of theophylline on density of central apnoeas and on incidence of periodic breathing; to compare the effect with age-related resolution of pneumogram abnormalities. Ninety-six infants (mean age 27.4 days; mean birth weight 2502 gm) with abnormal pneumographic results were randomly allocated to receive theophylline or placebo. The control group consisted of 94 healthy age- and weight-matched infants. After four weeks of treatment infants in the theophylline group had a significantly lower incidence (2.1% vs. 4.3%) and density of apnoeas > or = 15 sec (0.001 vs. 0.003). There were significantly less short apnoeas (> or = 6 sec.) in theophylline treated than in control infants (p < 0.01). The number of periodic breathing episodes showed a significant, presumably age-related reduction in both treatment groups. We conclude that theophylline is an effective agent in reducing the incidence and duration of apnoeas beyond what would be expected from age-related maturation of breathing.
