Changes in Paco2 and Paco2 during the induction of anaesthesia with thiopental suxamethonium, and intubation were investigated in 20 patients who received preoxygenation for 2 min, but no ventilation before intubation. Both in fit patients below the age of 60 years (Group I) and in patients above the age-several suffering from cardiopulmonary disease -(More)
Free-living amebae etiologically associated with central nervous system (CNS) infection in children have included Acanthamoeba, Naegleria, and recently, leptomyxid ameba. Two previously healthy children are reported with CNS infection caused by leptomyxid ameba, recently classified as Balamuthia mandrillaris. One child, a 27-month-old boy, had right(More)
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is common in adults with extreme obesity and can impact long-term health and survival. Liver biopsy is the only accurate test for diagnosis and staging, but is invasive and costly. Non-invasive testing offers an attractive alternate, but the overall accuracy remains a significant issue. This study was(More)
Preoperative administration of atropine was evaluated during induction of halothane anaesthesia with two administrations of suxamethonium 1 mg/kg body weight, 5 min apart. Sixty-eight healthy, adult patients were studied. They were divided into five groups according to dose and route of administration of atropine. ECG was continuously monitored. Serum(More)
The pharmacokinetics of methylprednisolone sodium succinate (MP) were studied in six neurosurgical patients under intensive treatment with large doses of MP, barbiturates, and mechanical hyperventilation. The study showed a remarkable level of enzyme induction within 24 hours after starting treatment, when the first blood samples were taken. The half-life(More)
Rebreathing in the Mapleson D system with a varying fresh gas flow (FGF) was measured during an experimental set-up, which consisted of a compliance lung delivering the exhaled gases with the same, fixed concentration throughout the experiment, a commercially available Bain's system and a respirator. While changes in compliance, airway resistance an dead(More)
