Clinical application of differential ventilation with selective positive end-expiratory pressure in adult respiratory distress syndrome.
Differential ventilation in the lateral position with positive end-expiratory pressure (PEEP) selectively applied to the dependent lung (DVSP) has been shown to reduce venous admixture and improve oxygenation without compromising cardiac output in short term studies of patients with acute respiratory failure. We have applied this ventilation technique as a long-term treatment in severe adult respiratory distress syndrome (ARDS) in an open clinical trial. Eleven patients with ARDS of varying aetiology were treated with DVSP for a total of 34 days. ⋯ We found a steady improvement in gas exchange over the first 24 hours in most patients. However, mortality rate was no lower than expected. Drawbacks with DVSP were increased demand on staff and difficulties with adequate endo-bronchial suctioning.

Inflammatory cytokines have been related to the development of adult respiratory distress syndrome (ARDS), shock, and multiple organ dysfunction syndrome (MODS). We tested the hypothesis that unfavorable outcome in patients with ARDS is related to the presence of a persistent inflammatory response. For this purpose, we evaluated the behavior of inflammatory cytokines during progression of ARDS and the relationship of plasma inflammatory cytokines with clinical variables and outcome. ⋯ Our findings indicate that unfavorable outcome in acute lung injury is related to the degree of inflammatory response at the onset and during the course of ARDS. Patients with higher plasma levels of TNF-alpha, IL-1 beta, IL-6, and IL-8 on day 1 of ARDS had persistent elevation of these inflammatory cytokines over time and died. Survivors had lesser elevations of plasma inflammatory cytokines on day 1 of ARDS and a rapid reduction over time. Plasma IL-1 beta and IL-6 levels were consistent and efficient predictors of outcome.

The use of extracorporeal life support in pediatric burn patients with respiratory failure.
Respiratory failure is the most common cause of death after thermal injury and may be caused by inhalation injury, acute respiratory distress syndrome (ARDS) or pneumonia. ARDS is usually associated with sepsis; however, it may also occur during burn shock, especially in patients that have a delayed or inadequate fluid resuscitation. During the past 24 months, five pediatric burn patients underwent extracorporeal life support (ECLS) for respiratory failure unresponsive to optimal medical management. ⋯ The patients who expired developed significant hemodynamic instability, coagulopathy, and hemorrhage from their burn wounds. The extent and degree of burn injury did not seem to alter the outcome. Indications for considering ECLS in the pediatric burn patient are unmanageable, life threatening pulmonary insufficiency in patients that undergo a relative short course of pre-ECLS ventilator support.(ABSTRACT TRUNCATED AT 250 WORDS)
