To determine the predictors of outcome in cardiac surgical patients with prolonged ICU stay. ⋯ Preoperative health status and early organ failure were not predictive of late hospital mortality. The pattern of late organ failure associated with hospital mortality changed with time.

Thoracoscopy is an excellent means for staging esophageal cancer. Staging of esophageal carcinoma facilitates prognostication and allocation of patients to appropriate treatment regimens. ⋯ Routine thoracoscopic and laparoscopic lymph node staging has been used in patients with esophageal carcinoma with excellent results. Thoracoscopy can allocate patients for neoadjuvant therapy and help avoid an unnecessary thoracotomy in patients found to have gross spread of locoregional disease.

Patients with ARDS typically have functionally small lungs. A growing body of clinical and experimental evidence has demonstrated that mechanical ventilation that results in high transpulmonary pressure gradients and overdistention of lung units will potentiate the acute lung injury in patients with ARDS. ⋯ The goal of this article is to provide a simple and practical approach to the management of PCV in patients with ARDS. Implicit in our approach is the use of a ventilator with PCV software and waveform capabilities.

Multicenter Study Clinical Trial
Clinical characteristics of patients with acute pulmonary embolism stratified according to their presenting syndromes.
The purpose of this investigation is to determine the characteristics of the history, physical examination, chest radiograph, and ECG, and the ventilation/perfusion (V/Q) lung scan probability in patients with pulmonary embolism (PE) stratified according to their presenting syndrome. ⋯ Many of the findings in the various syndromes of PE can be understood in terms of the severity of PE as it increases from mild with the pulmonary infarction syndrome to moderate with the isolated dyspnea syndrome to severe with circulatory collapse. The prevalence of various clinical and laboratory characteristics of patients with the syndrome of pulmonary infarction, isolated dyspnea, or circulatory collapse may give clues to the diagnosis or suggest characteristics that may reduce the likelihood of inadvertently discarding the diagnosis of PE.
