The mortality rate of patients with acute respiratory distress syndrome (ARDS) is still high despite the use of protective ventilatory strategies. We sought to examine the pharmacological effects of glutamine (GLN) in a two-hit model of endotoxin-induced inflammation followed by ventilator-induced lung injury (VILI). We hypothesized that the administration of GLN ameliorates the VILI. ⋯ The administration of GLN given immediately prior to MV may be beneficial in the context of reducing VILI.

Chemical pleurodesis can be palliative for recurrent, symptomatic pleural effusions in patients who are not candidate for a thoracic surgical procedure. We hypothesized that effective pleurodesis could be accomplished with a rapid method of pleurodesis as effective as the standard method. ⋯ Rapid pleurodesis with talc slurry is safe and effective and it can be performed in an outpatient basis.

Nonintubated thoracic surgery has been used in procedures including pleura, lungs and mediastinum. Appropriate anesthesia techniques with or without sedation allow thoracic surgery patients to avoid the potential risks of intubated general anesthesia, particularly for the high-risk patients. However, nonintubated anesthesia for thoracic surgery has some benefits as well as problems. In this review, the background, indication, perioperative anesthetic consideration and management, and advantages and disadvantages are discussed and summarized.

Simultaneous improvement in respiratory maintenance and bleeding control increases survival of patients with life-threatening hemoptysis. Endobronchial blockade is an effective method and is preferred for emergency hemostasis. However, when the volume of hemoptysis is high, emergency hemostasis and airway maintenance are impossible due to flooding of blood into the airway. We used extracorporeal membrane oxygenation (ECMO) to overcome these limitations in a patient with massive hemoptysis due to severe blunt trauma and succeeded in saving the life by inducing a near-total airway obstruction.

Primary malignant pericardial mesothelioma (PMPM) is an extremely rare, highly lethal and often misdiagnosed tumor. We report a 60-year-old woman complaining of dry cough, shortness of breath and exertional dyspnea due to a large pericardial effusion. The pericardial fluid volume declined after pericardiocentesis; analysis of the fluid revealed malignant cells and was negative for tuberculosis. ⋯ The patient's symptoms marginally improved after partial pericardiectomy, and a diagnosis of pericardial mesothelioma was made on pathology. However, her symptoms continued to aggravate, and she died 8 months after presentation. Pericardial mesothelioma should be discovered earlier to treat patients who develop repeatedly pericardial effusion after pericardiocentesis and pericardial tamponade or those develop constrictive pericarditis.
