Methods |
Two‐period crossover trial with randomized order of treatment. Single center study. |
Participants |
Preterm infants with > apneas in 24 hours (n = 12).
Gestation 26 ‐ 32 weeks (mean 29.5).
Birth weight 800 ‐ 1700 g (mean 1210 g).
Age 2 ‐ 45 days (mean 14 days).
Four in oxygen, no theophylline, no secondary cause of apnea. |
Interventions |
Single crossover with two consecutive, equal alternate 4 ‐ 8 hour periods of regularly rocking bed (using bellows under the tray) at 10 ‐ 22 cycles per minute, and non‐rocking bed. |
Outcomes |
Polygraphic recorded apnea (> 12 seconds), bradycardia (< 100 bpm) and transcutaneous oxygen concentration.
Need for stimulation. |
