Case ReportsBronchopulmonary distress associated with toxic epidermal necrolysis.
We describe here a patient with severe TEN and respiratory distress and we review the subject of bronchopulmonary symptoms in TEN. Even if pseudostratified ciliated involvement is uncommon, bronchial lesions in the absence of other known causes, should be specifically related to TEN. The mechanisms of pulmonary involvement and ARDS associated with TEN are discussed.

Round table conference on ventilatory failure, Brussels, Belgium, March 16-18, 1991.
It was possible to reach agreement on several important issues relating to VF. First, the phenomenon of CO2 retention may have both pathophysiologic and compensatory components. There is increased awareness of the nature, intensity, and significance of the cross-talk between the ventilatory control center and the pump itself, as expressed in breathing pattern and indices of ventilatory drive. ⋯ In the acute setting, measures to limit alveolar distention, such as controlling airway pressure, revising blood gas targets, and/or using adjunctive methods for blood gas exchange may avoid barotraumatic edema and rupture. The potential for non-invasive ventilation to avert intubation, facilitate ventilator withdrawal, and help patients with chronic VF to achieve compensation without machine dependence is now being actively investigated. This two day conference proved a stimulating forum for interchange of ideas regarding the state of the field, and allowed many opportunities for scientific interaction, both during outside the formal program.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical TrialIsoflurane for prolonged sedation in the intensive care unit; efficacy and safety.
To compare isoflurane with midazolam for prolonged sedation in ventilated patients. ⋯ Isoflurane is a useful agent for prolonged sedation of ventilated patients and does not have any adverse effect on the cardiorespiratory system or on hepatic, renal or adrenal function.

The development of the flexible, fiberoptic bronchoscope has made bronchoscopic examinations possible in ICU patients undergoing mechanical ventilation. Over the years, the number of such procedures has greatly increased, with both diagnostic and therapeutic objectives, such as performing difficult intubation, management of atelectasis and hemoptysis, diagnosis of nosocomial pneumonia in ventilated patients, and early detection of airway lesions in selected situations, such as high-frequency ventilation. The complication rate can be kept low if the endoscopist has a precise knowledge of the many pathophysiological and technical facets particular to bronchoscopy under these difficult conditions. This article reviews some of these aspects, in the light of our personal experience.

Comparative StudyContinuous positive airway pressure by face mask or mechanical ventilation in patients with human immunodeficiency virus infection and severe Pneumocystis carinii pneumonia.
We reviewed the records of 44 patients with AIDS who had 45 episodes of severe Pneumocystis carinii pneumonia (PCP). While 9 patients required intubation and mechanical ventilation (MV) on admission, continuous positive airway pressure (CPAP) by face mask was the initial measure in 36 episodes. There were 25 patients managed with CPAP alone, 23 of whom survived. ⋯ The in-hospital mortality for severe PCP in this study was 33% overall, and reached 65% for mechanically ventilated patients. The 1-year survival was 43% (95% confidence interval, 28%-58%). These data confirm the improved prognosis for patients with AIDS and severe PCP, and suggest that mask CPAP may be an adequate mean of ventilatory support in this setting.
