Randomized Controlled Trial Multicenter Study Clinical Trial
Parental education and guided self-management of asthma and wheezing in the pre-school child: a randomised controlled trial.
The effects on morbidity were examined of providing an educational intervention and a written guided self-management plan to the parents of pre-school children following a recent attendance at hospital for asthma or wheeze. ⋯ These results do not support the hypothesis that the introduction of an educational package and a written guided self-management plan to the parents of pre-school children with asthma who had recently attended hospital for troublesome asthma or wheeze reduces morbidity over the subsequent 12 months.

Review
The pulmonary physician in critical care 1: pulmonary investigations for acute respiratory failure.
This is the first in a series of reviews of the role of the pulmonary physician in critical care medicine. The investigation of mechanically ventilated patients is discussed, with particular reference to those presenting with acute respiratory failure and diffuse pulmonary infiltrates.

Randomized Controlled Trial Clinical Trial
Non-invasive proportional assist and pressure support ventilation in patients with cystic fibrosis and chronic respiratory failure.
Patients with advanced cystic fibrosis can benefit from non-invasive positive pressure ventilation (NPPV) for the treatment of acute decompensation as well as for the management of chronic respiratory failure. This study was undertaken to compare the physiological effects of non-invasive proportional assist ventilation (PAV) and pressure support ventilation (PSV) on ventilatory pattern, transcutaneous blood gas tensions, and diaphragmatic effort in stable patients with cystic fibrosis and chronic CO2 retention. ⋯ These results show that short term administration of nasal PAV and PSV to patients with stable cystic fibrosis with chronic respiratory insufficiency is well tolerated, improves ventilation and blood gas tensions, and unloads the diaphragm.

Traditionally, patients with acute respiratory failure due to chronic obstructive pulmonary disease (COPD) admitted to the intensive care unit (ICU) are believed to have a poor outcome. A study was undertaken to explore both hospital and long term outcome in this group and to identify clinical predictors. ⋯ Despite the need for invasive mechanical ventilation in most of the study group, good early survival was observed. Mortality in the long term was significant but acceptable, given the degree of chronic respiratory impairment of the group.
