Abstract
Background: The effects of body positioning (BP) of preterm infants (PT) receiving nasal CPAP was not well evaluated in the literature.
Objective: To evaluate the possible effect of four BP (prone, supine, left and right lateral) on respiratory parameters of PT using nasal CPAP.
Methods: Sixteen infants with < 37 weeks and < 2500g receiving nasal CPAP were studied. Each PT was submitted to the four BP; supine (A), right lateral (B), prone (C) and left lateral (D), in one of the four randomized sequences.1- A, D, C, B; 2- C, A, B, D; 3- B, C, D, A e 4- D, B, A, C. Data were collected every 10 minutes during the 60 minutes that the infant remained at the position.
Results: Infants had GA of 29.7±2 weeks, BW of 1353±280g, 37.5% receive antenatal corticosteroids, 9 (56.3) were male. Infants received 5 minutes Apgar of 8.7 (6 to 10), and were 2.7 (1 to 7) days old. They were in very stable clinical condition. With mean Silverman & Anderson bulletin (SAB) of 0.25 (0 to 1), receiving ≤30% of oxygen and PEEP ranging from 4 to 6. No statistical or clinical relevant difference regarding respiratory and cardiac frequency, respiratory pause, SAB or oxygen saturation was found. Nasal prong was more frequently out of nostrils at prone position (56,25%) than other BP (p< 0.01).
Conclusion: Respiratory parameters of clinically stable preterm infants receiving nasal CPAP are not affected by BP. At prone position nasal prong was found more frequently out of nostrils.
