BACKGROUND Inhalational induction with sevoflurane and nitrous oxide is frequently used for Laryngeal Mask Airway (LMA; Laryngeal Mask Company, Henley-on-Thames, United Kingdom) insertion in children. The authors determined the influence of nitrous oxide on the minimum alveolar concentration (MAC) of sevoflurane for LMA insertion. METHODS One hundred(More)
BACKGROUND The authors compared the manufacturer's weight-based formula (size 3 for weight < 50 kg, size 4 for weight 50-70 kg, and size 5 for weight > 70 kg) with a sex-based formula (size 4 for women and size 5 for men) for selecting the appropriate size of ProSeal laryngeal mask airway. METHODS Two hundred thirty-seven healthy, anesthetized, paralyzed(More)
UNLABELLED We compared the Size 4 and 5 ProSeal laryngeal mask airway (PLMA) in men and the Size 3 and 4, and 4 and 5 PLMA in women in terms of 1) ease of insertion, 2) oropharyngeal leak pressure (OLP), 3) ease of ventilation at a tidal volume of 10 mL/kg, 4) gas exchange, 5) location of gas leak, 6) anatomic position of the airway and drain tube, and 7)(More)
BACKGROUND Fatty split-liver and living-related liver transplantation is associated with massive hepatocellular necrosis during acute rejection. Uncoupling protein (UCP)-2 is a potential regulator of energy expenditure and ATP production. We investigated the role of UCP-2 and the effects of a metalloprotease inhibitor, Y-39083, on hepatocellular injury in(More)
BACKGROUND AND OBJECTIVES To evaluate the effects of aging on lidocaine pharmacokinetics, the plasma concentrations of total and free lidocaine and its metabolites were measured during continuous thoracic epidural anesthesia in middle-aged (age 41 +/- 9 years, n = 7) and elderly (age 72 +/- 2 years, n = 7) male patients. METHODS After establishment of(More)
BACKGROUND We investigated the advantages of intraoperative transesophageal echocardiography (TEE) during inferior vena caval tumor thrombectomy in renal cell carcinoma (RCC). METHODS Five patients with RCC that extended into the inferior vena cava (IVC) underwent radical nephrectomy. To remove the tumor thrombus in the IVC, an inflated Fogarty balloon(More)
Neutrophil elastase, which enhances intercellular adhesion molecule-1 (ICAM-1) expression in endothelial cells, plays an important role in ischemia/reperfusion injury. Here, we investigated signal transduction of ICAM-1 expression in endothelial cells stimulated by neutrophil elastase. Pretreatment of animals with the neutrophil elastase inhibitor,(More)
UNLABELLED We tested the hypothesis that a silicone-based wire-reinforced tracheal tube with a hemispherical bevel is superior to a polyvinyl chloride (PVC)-based precurved tube with a conventional diagonal bevel for nasotracheal intubation. Eighty anesthetized paralyzed adults (ASA physical status I-II) requiring nasotracheal intubation for tonsillectomy(More)
PURPOSE We compare the StyletScope fibreoptic stylet (FOS) and the Satin Slip conventional metal stylet (CMS), during simulated difficult airway management with manual-in-line stabilization in terms of ease of intubation and esophageal intubation. METHODS 193 patients (ASA I-II, 18-80 yr) were studied in a non-crossover, randomized fashion. Manual-in-line(More)
There is no established or effective standard therapy for metastatic biliary tract cancer, resulting in poor prognosis. Recently, we performed combination chemotherapy of irinotecan and low-dose cisplatin (I/low-P) for three consecutive patients with metastatic biliary tract cancer. The regimen of I/low-P therapy consisted of irinotecan (60 mg/m(2)) and(More)
