Randomized Controlled Trial
Recruitment maneuver in prevention of hypoxia during percutaneous dilational tracheostomy: randomized trial.
Percutaneous dilational tracheostomy (PDT) can potentially lead to hypoxia and alveolar derecruitment. The aim of this prospective study was to evaluate the efficacy of performing a recruitment maneuver (RM) before tracheostomy, in order to improve oxygenation. ⋯ Our study suggests that application of RM before PDT could be useful to avoid hypoxemia following such procedure, by reducing fall in P(aO(2)) and preventing the decrease in oxygenation values below baseline at 6 hours.

Randomized Controlled Trial
CPAP has no effect on clearance, sputum properties, or expectorated volume in cystic fibrosis.
Positive expiratory pressure (PEP) is used for airway clearance in cystic fibrosis (CF) patients. Hypertonic saline (HTS) aerosol increases sputum expectoration volume and may improve respiratory secretion properties. CPAP may also be used to maintain airway patency and mobilize secretions. To evaluate if CPAP would increase the beneficial clearance effect of HTS in subjects with CF, we investigated the effects of CPAP alone and CPAP followed by HTS on sputum physical properties and expectoration volume in CF subjects. ⋯ CPAP alone had no effect on mucus clearance, sputum properties, or expectorated volume, and did not potentiate the effect of HTS alone in CF subjects.
