Randomized Controlled Trial
Prophylactic use of helmet CPAP after pulmonary lobectomy: a prospective randomized controlled study.
Patients undergoing pulmonary lobectomy carry a high risk of respiratory complications after surgery. The postoperative prophylactic treatment with helmet CPAP may prevent postoperative acute respiratory failure and improve the P(aO(2))/F(IO(2)). ⋯ The prophylactic use of helmet CPAP improved the P(aO(2))/F(IO(2)), but the oxygenation benefit was not lasting. In our study, helmet CPAP was a secure and well tolerated method in subjects who underwent pulmonary lobectomy. It might be safely applied whenever necessary.

Randomized Controlled Trial
Randomized controlled trial of a breath-activated nebulizer in patients with exacerbation of COPD.
Exacerbations of COPD (ECOPD) are characterized by increased dyspnea due to dynamic pulmonary hyperinflation. This study sought to determine whether the AeroEclipse II breath-activated nebulizer (BAN) would produce greater bronchodilator responses than a continuous flow small-volume nebulizer (SVN) in patients with ECOPD. ⋯ In this cohort of patients with ECOPD, a BAN was more effective in reducing lung hyperinflation and respiratory frequency than a continuous-flow SVN.

Comparative Study
Nocturnal oximetry and transcutaneous carbon dioxide in home-ventilated neuromuscular patients.
Pulse oximetry alone has been suggested to determine which patients on home mechanical ventilation (MV) require further investigation of nocturnal gas exchange. In patients with neuromuscular diseases, alveolar hypoventilation (AH) is rarely accompanied with ventilation-perfusion ratio heterogeneity, and, therefore, oximetry may be less sensitive for detecting AH than in patients with lung disease. ⋯ Pulse oximetry alone is not sufficient to exclude AH when assessing home MV efficiency in patients with neuromuscular diseases. Both P(tcCO(2)) and S(pO(2)) should be recorded overnight as the first-line investigation in this population.

Severe acute asthma in children is associated with substantial morbidity and may require pediatric ICU (PICU) admission. The aim of the study was to determine risk factors for PICU admission. ⋯ Physicians and parents should be aware of these risk factors, and efforts should be made to counteract them.

Patients with COPD and patients with bronchiectasis undertake airway clearance therapy and exercise as part of management, but the effect of these activities on gastroesophageal acid exposure is unknown. This study aimed to determine if positive expiratory pressure (PEP) therapy and standardized exercise tasks were associated with increased gastroesophageal reflux. ⋯ Episodes of gastroesophageal reflux may occur during physiotherapy tasks, including airway clearance therapy using mouthpiece PEP, the 6MWT, and a measure of upper limb movement. However, as these activities did not increase the frequency of these events, no modifications to these tasks to minimize the occurrence of gastroesophageal reflux are necessary.
