Factors predicting successful noninvasive ventilation in acute lung injury.
Noninvasive ventilation (NIV) has been successfully used to treat various forms of acute respiratory failure. It remains unclear whether NIV has potential as an effective therapeutic method in patients with acute lung injury (ALI). The aims of this study were to determine factors predicting the need for endotracheal intubation in ALI patients treated with NIV, and to promote the selection of patients suitable for NIV. ⋯ We determined an APACHE II score of more than 17 and a respiratory rate of more than 25 breaths x min(-1) after 1 h of NIV as factors predicting the need for endotracheal intubation in ALI patients treated with NIV.

ReviewGuideline-oriented perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease.
Increased airway hyperresponsiveness is a major concern in the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease. Guidelines using evidence-based medicine are continually being updated and published regarding the diagnosis, treatment, and prevention of these respiratory disorders. ⋯ Awareness of recent guidelines is thus important in the management of patients with airway hyperresponsiveness. This review covers the most recent guidelines for the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease.

Case ReportsAminophylline reversal of prolonged postoperative sedation induced by propofol.
Propofol is frequently used for intravenous sedation or anesthesia in ambulatory and office-based anesthesia. Although awakening is usually rapid, there are instances of delayed recovery from propofol anesthesia. ⋯ There were no side effects or delayed re-sedation after the administration of aminophylline. Our study suggests that aminophylline could be a clinically useful propofol antagonist.

Case ReportsAn unusual case of airway obstruction at the tip of an endotracheal tube caused by insertion of a nasogastric tube.
We report an unusual case of ventilatory impediment caused by the obstruction of an endotracheal tube (ETT) by a nasogastric (NG) tube. A 72-year-old woman with bronchial asthma was scheduled for colostomy closure. An ETT of 7.5-mm internal diameter (ID) could not be advanced, and finally a 5.0-mm ID ETT was placed, because she had post-intubation tracheal stenosis. ⋯ She was treated for an asthmatic attack, but her respiratory condition did not recover. We then exchanged the ETT for a laryngeal mask airway (LMA) and removed the NG tube. It was suspected that the cause of the airway obstruction was that the NG tube in the esophagus compressed the membranous portion of the stenotic trachea and the tip of the ETT was obstructed.

Comparative StudyChanges in polymorphonuclear leukocyte elastase concentrations and hemolysis parameters in patients transfused with different blood preparations, and in the blood preparations themselves.
Massive blood transfusion induces hemolysis and increases polymorphonuclear leukocyte elastase (PMNE) concentration. The purpose of this study was to compare hemolysis and PMNE concentrations in massive blood transfusions with three different preparations. ⋯ During the storage of MAP-CRC, CPD-CRC, and WB, CPD-CRC had the greatest hemolysis and WB had the highest concentration of PMNE. Patients who received massive blood transfusion of MAP-CRC had the least hemolysis and the lowest concentration of PMNE.
