Background: Desflurane's short emergence time supports fast track anaesthesia. Data on the rate of upper airway complications and emergence time when desflurane is used with laryngeal mask airway (LMA) are controversial and limited.
Objectives: To compare recovery time variables and the rates of upper airway adverse events in patients with an LMA undergoing general surgery with desflurane, sevoflurane, isoflurane or propofol anaesthesia.
Background: The authors determined the influence of cuff volume and anatomic location on pharyngeal, esophageal, and tracheal mucosal pressures for the esophageal tracheal combitube.
Methods: Twenty fresh cadavers were studied. Microchip sensors were attached to the anterior, lateral, and posterior surfaces of the distal and proximal cuffs of the small adult esophageal tracheal combitube.
Congenital or acquired forms of the long Q-T syndrome may result in ventricular tachycardia known as torsade de pointes. Many drugs including volatile anaesthetics modify the Q-T interval. Sevoflurane is known to prolong of the rate-corrected Q-T interval (Q-Tc).

The effects of sildenafil (Viagra) on hemodynamics and pulmonary gas exchange remain uncertain. The aim of this study was to investigate what effect sildenafil had on gas exchange. A total of 24 anesthetized pigs were randomly assigned into four groups of six animals each: Group Low received 25 mg of sildenafil, which is equivalent to half the recommended dose for humans; group Normal received 50 mg; group High received 100 mg; and one group served as control.

Thirty-six unpremedicated women due for gynaecological surgery were examined for time-dependent prolongation of the QT interval in the electrocardiogram (ECG) before and after induction of anaesthesia using either sevoflurane or propofol. The conventional inhalational technique to induce anaesthesia with sevoflurane. ECG recordings were taken before, 2, 5 and 10 min after drug administration.
