Case Reports
Extracorporeal life support for the treatment of adult respiratory distress syndrome after burn injury.
The pediatric population comprises 38% of hospital admissions for burns in the United States. In the age group of 1- to 14-year-olds, a 62% total body surface area burn represents the median lethal dose and carries a lower mortality rate for burn size than in infants or adults. Adult respiratory distress syndrome (ARDS) is a common accompaniment to severe burn injury. ⋯ ECMO was successfully terminated after 28 days. Open lung biopsy specimens obtained before instituting ECMO and on ECMO day 26 exhibited severe but histologically reversible lung disease and improved alveolar aeration as a result of treatment. This is the first reported survival of a pediatric patient with thermal injury and ARDS by using ECMO for the treatment of respiratory failure.

Comparative StudyInflammatory markers: superior predictors of adverse outcome in blunt trauma patients?
To assess whether variables reflective of early metabolic responses to injury are predictors of outcome in critically ill trauma patients. ⋯ Readily obtainable inflammatory marker measurements may better reflect the summation effects of the early perfusion deficit and tissue injury in the blunt trauma patient compared with conventional measures of injury severity.

Clinical Trial
Haemodynamic evaluation during small volume resuscitation in patients with acute respiratory failure.
In addition to the invasive haemodynamic monitoring procedures, an on-line assessment of cardiac performance by means of transoesophageal echocardiography might have a certain role in small volume resuscitation of patients with acute respiratory failure or Adult Respiratory Distress Syndrome (ARDS). The goal of this investigation was therefore to determine the effects of a hypertonic hyperoncotic solution, hypertonic hydoxyethl-starch (HHES), (HHES = HES [200.000/0.6-0.66; 60 g l-1; Leopold, Graz; Austria] combined with NaCl [75 g l-1) on haemodynamics and cardiac performance using the transoesophageal echocardiography. After institutional approval we investigated 23 patients suffering from septic ARDS after trauma or major surgery during four periods of resuscitation. ⋯ A significant improvement in cardiac output was associated with increasing stroke volumes, oxygen delivery and oxygen consumption (see Tables 1 and 2). Small volume resuscitation also resulted in significant increases of endsystolic and endiastolic left ventricular areas and the corresponding calculated wall stress (Figs 1-3). We conclude from our preliminary data that when using HHES, only modest fluid resuscitation was sufficient to restore adequate preload and oxygen delivery in patients with sepsis-related acute respiratory failure.

Comparative StudyInfrared end-tidal CO2 measurement does not accurately predict arterial CO2 values or end-tidal to arterial PCO2 gradients in rabbits with lung injury.
End-tidal PCO2 (PETCO2) measurements from two commercially available neonatal infrared capnometers with different sampling systems and a mass spectrometer were compared with arterial PCO2 (PaCO2) to determine whether the former could predict the latter in mechanically ventilated rabbits with and without lung injury. The effects of tidal volume, ventilator frequency and type of lung injury on the gradient between PETCO2 and PaCO2 (delta P(a-ET)CO2) were evaluated. Twenty rabbits were studied: 10 without lung injury, 5 with saline lavage and 5 with lung injury by meconium instillation. ⋯ The delta P(a-ET)CO2 was greater in rabbits with injured than noninjured lungs (P < 0.05). The delta P(a-ET)CO2 was similar among capnometers regardless of tidal volume, ventilator frequency, or type of lung injury. The 95% confidence interval of plots PaCO2 against PETCO2 was large for rabbits with injured and noninjured lungs.(ABSTRACT TRUNCATED AT 250 WORDS)

ReviewThe American-European Consensus Conference on ARDS. Definitions, mechanisms, relevant outcomes, and clinical trial coordination.
The acute respiratory distress syndrome (ARDS), a process of nonhydrostatic pulmonary edema and hypoxemia associated with a variety of etiologies, carries a high morbidity, mortality (10 to 90%), and financial cost. The reported annual incidence in the United States is 150,000 cases, but this figure has been challenged, and it may be different in Europe. ⋯ The American-European Consensus Committee on ARDS was formed to focus on these issues and on the pathophysiologic mechanisms of the process. It was felt that international coordination between North America and Europe in clinical studies of ARDS was becoming increasingly important in order to address the recent plethora of potential therapeutic agents for the prevention and treatment of ARDS.
