Routine neonatal postextubation chest physiotherapy: a randomized controlled trial.

OBJECTIVE: To test the effects of a neonatal postextubation programme on the incidence of postextubation collapse and adverse outcomes.

METHODS: A randomized controlled trial was carried out at the Mater Mothers' Hospital, Brisbane. Mechanically ventilated infants were randomized into one of two groups, physiotherapy group--which involved a regimen of chest wall percussion and oropharyngeal suctioning and control group - which involved suctioning without the percussion unless indicated. Chest X-rays were taken at 6 h and at 24 h postextubation. The primary outcome measure was postextubation collapse as determined by a paediatric radiologist blinded to the group allocation.

RESULTS: One hundred and seventy-seven neonates were enrolled in the trial between 1997 and 1999. After an interim analysis, the trial was stopped early. No statistically significant difference was shown in the rate of postextubation collapse (15 of 87 (17.2%) physiotherapy group and 17 of 86 (19.8%) control group (P = 0.85)). No differences were shown between the groups in the number of apnoeic or bradycardic events, duration of requirement for supplemental oxygen or the need for re-intubation within 24 h postextubation.

CONCLUSION: The results of this trial suggest that a routine neonatal postextubation chest physiotherapy programme for all infants is not indicated. There was no evidence that chest physiotherapy is associated with any adverse outcomes.
