Randomized Controlled Trial Clinical Trial
Ketoconazole prevents acute respiratory failure in critically ill surgical patients.
Effective prophylaxis against acute respiratory failure (ARDS) has not been established. This study investigated whether or not ketoconazole could prevent ARDS in critically ill surgical patients. Seventy-one Surgical Intensive Care Unit (SICU) patients without liver dysfunction received either ketoconazole (n = 35), 200 mg daily via the gastrointestinal tract, or placebo (n = 36), for 21 days or until discharge from the SICU, in a prospective, randomized, double-blind study. ⋯ The incidence of ARDS was decreased among ketoconazole patients compared to placebo (6% vs. 31%; p less than 0.01), as was median SICU stay (7.0 days vs. 15.5 days; p less than 0.05), and median SICU cost (+5,600. vs. +12,400.; p less than 0.05). Mortality is increased with ARDS after trauma and surgery. We conclude that ketoconazole prevents ARDS, shortens SICU stay, and lowers hospital costs.

Adult respiratory distress syndrome (ARDS) culminates in inadequate oxygen delivery to the tissues. There are numerous inciting factors for this syndrome. Several therapies including the prophylactic use of antibiotics and steroids are controversial; even mechanical ventilatory support has controversial elements. The cornerstone of treatment remains supportive care until the cause of ARDS has resolved.

Effect of almitrine on ventilation-perfusion distribution in adult respiratory distress syndrome.
Almitrine improves ventilation/perfusion relationships (VA/Q) in COPD, but its effects in ARDS, in which VA/Q mismatching is the cause of severe hypoxemia, are not known. The effects of almitrine on pulmonary gas exchange and circulation were assessed in 9 patients with ARDS who were sedated, paralyzed, and mechanically ventilated at constant FlO2 (range, 0.48 to 0.74). Systemic and pulmonary hemodynamics, conventional gas exchange, and the VA/Q distribution by the multiple inert gas elimination technique (MIGT) were measured before (baseline), during (ALM 15), at the end of (ALM 30), and at 30-min intervals after (POSTALM 30, 60, and 90) the intravenous infusion of 0.5 mg/kg body weight of almitrine over 30 min. ⋯ The Ppa increased from 26 +/- 5 to 30 +/- 5 mm Hg without changes in QT. Changes were transient, returning toward baseline 30 min after stopping the infusion of the drug. Almitrine significantly reduced the VA/Q inequalities present in ARDS and may be useful in the management of those patients.

The premature infant's respiratory response to mechanical ventilation.
Comparisons of the components of ventilator waveform were made in two groups of preterm infants ventilated for the respiratory distress syndrome. Infants actively expiring against positive pressure inflation were compared to infants not showing this interaction. ⋯ The two groups were well matched for gestational and postnatal age and there were no other significant differences in the components of ventilator waveform. Adoption of a ventilator waveform with a shorter positive pressure plateau and less steep rise in positive pressure might reduce the incidence of active expiration and hence pneumothoraces.
