Tracheal intubation (TI) is a difficult skill to acquire and its proficiency deteriorates over time if not regularly practiced. However, inexperienced personnel may be required to perform airway management in emergency situations. We compared a novel supraglottic device, i-gel, with laryngeal mask airway classic (cLMA) and TI devices in regard to total success count, time required for placement, and difficulties encountered by novice personnel using a manikin model. ⋯ An i-gel may be useful for emergency airway management by inexperienced personnel. Further studies in a clinical setting are necessary to confirm these findings.

Case Reports
[Management of a child with Swyer-James syndrome who underwent flexible bronchoscopy under general anesthesia].
Swyer-James syndrome (SJS) is a rare syndrome characterized by hyperlucency of one or more lobes of the unilateral lung and decreased pulmonary vascularity which is considered to be secondary to the childhood obliterative bronchiolitis. We report anesthetic management of a girl with SJS who underwent flexible bronchoscopy. A 15-year-old girl weighing 47 kg was referred to our hospital with suspected SJS. ⋯ Spontaneous respiration was maintained by using laryngeal mask airway to prevent the pressure alveolar damage by positive pressure ventilation. Flexible bronchoscopy was performed safely by using topical laryngeal lidocaine administration and additional bolus of propofol. Her postoperative course was uncomplicated and she was discharged on the following day.

The clinical criteria of acute respiratory distress syndrome (ARDS) defined by the American-European Consensus Conference (AECC) in 1994 was relevant to clinical practice, trials, and researches for two decades. However, a number of issues with the AECC definition have become apparent. ⋯ In the second section, the clinical significance and limitation of radiographic imaging, especially, high-resolution CT (HRCT) findings in ARDS were addressed. Although the early exudative phase of ARDS can not be detected even by HRCT, pulmonary fibroproliferation assessed by HRCT in patients with early ARDS predicts increased mortality with an increased susceptibility to multiple organ failure, along with ventilator dependency and its associated outcomes.

Randomized Controlled Trial
[Continuous infusion of low-dose remifentanil for palliation of pain with epidural catheterization].
To prospectively determine the safety and effectiveness of continuous infusion of low-dose remifentanil for the reduction of pain in patients for epidural catheterization. ⋯ Continuous infusion of low-dose remifentanil is a safe and effective method for palliation of pain in epidural catheterization.

We have patients who develop lung injury after surgery even they are without lung diseases preoperatively. What is the cause of this perioperative complication? Can we prevent postoperative lung injury by any measures during surgery? In the present paper, the etiology of acute respiratory distress syndrome (ARDS) is reviewed and possible methods to prevent ARDS is discussed. Inflammation occurs during surgery, the degree of which depends on multiple factors including surgical insults, the use of cardiopulmonary bypass (CPB), ischemia and reperfusion of any organ during surgery, transfusion, and organ damages. ⋯ Mechanical ventilation does not initiate lung injury by itself; however, conventional mechanical ventilation (tidal volume of 10-12 ml x kg-1 ideal body weight) may induce ARDS if lungs are primed. Accordingly, lung protective strategies should be carried out if patients have such condition or does receive such surgery. The brief outline of the lung protective strategies is to reduce tidal volume, to apply open lung approach with positive end-expiratory pressure and lung recruitment maneuver, and to avoid any lung lesion causing hypoxia during CPB or one-lung ventilation.
