Case ReportsBronchoscope-guided intubation through a Laryngeal Mask Airway Supreme in a patient with a difficult-to-manage airway.
We report a case of an obese patient who presented with laryngeal edema and difficult ventilation after failed attempts to intubate. A Laryngeal Mask Airway Supreme (LMA Supreme) reestablished the ventilation and allowed bronchoscope- guided intubation of the trachea. The case suggests that the LMA Supreme may be useful in patients with a difficult airway.

Desflurane requirements for laryngeal mask airway insertion during inhalation induction.
We hypothesized that the simultaneous use of low concentrations (<6%) of desflurane, nitrous oxide (N(2)O), and fentanyl would allow a laryngeal mask airway (LMA) to be inserted safely with inhalation induction of desflurane, even in nonparalyzed patients. This prospective, observational study was performed to determine the 50% effective concentration (EC(50)) of desflurane for LMA insertion in such patients. ⋯ We demonstrated that N(2)O-desflurane inhalation induction with a normal tidal breathing technique after premedication with fentanyl can be used safely without any adverse airway events in nonparalyzed patients. In such patients, the EC(50) of desflurane for successful LMA insertion was 3.61 +/- 0.31% (95% CI, 3.13-3.90).

Case ReportsAnesthetic management of a child with Langer-Giedion (TRPS II) syndrome.
We describe the anesthetic and perioperative management of a child with Langer-Giedion syndrome (trichorhinophalangeal syndrome type II). This is a very rare genetic syndrome caused by 8q chromosome deletion. The clinical features of this syndrome include craniofacial and urogenital abnormities, variable postnatal growth deficiency with mental retardation, multiple exostoses, hyperflexible joints, and recurrent respiratory tract infections. Potential perioperative problems are highlighted.

Recovery of dynamic balance after general anesthesia with sevoflurane in short-duration oral surgery.
Recovery of dynamic balance, involving adjustment of the center of gravity, is essential for safe discharge on foot after ambulatory anesthesia. The purpose of this study was to assess the recovery of dynamic balance after general anesthesia with sevoflurane, using two computerized dynamic posturographies. ⋯ The recovery times for dynamic balance and psychomotor function seem to be within 150 min after emergence from general anesthesia with sevoflurane in patients undergoing oral surgery of less than 2-h duration.

Case ReportsLife-threatening spontaneous hemothorax in a patient with thrombotic thrombocytopenic purpura.
Spontaneous hemothorax in the left pleural space occurred suddenly in a patient with thrombotic thrombocytopenic purpura (TTP). In spite of massive blood transfusion, the hemorrhage could not be stopped. The patient suffered shock due to tension hemothorax and hypovolemia, resulting in cardiac arrest. ⋯ The main cause of the bleeding was rupture of the left intercostal vein. TTP is a severe microvascular occlusive thrombotic microangiopathy that can induce congestion, vasculitis, and ischemia. This mechanism is thought to have been involved in the rupture of the intercostal vein in the present patient.
