Randomized Controlled TrialEffect of landiolol hydrochloride on suxamethonium-induced neuromuscular block.
The aim of this study was to examine the effect of landiolol hydrochloride, an ultrashort-acting beta(1)-blocker, on suxamethonium-induced neuromuscular block. ⋯ Landiolol delayed recovery from suxamethonium-induced paralysis. However, the interaction between the drugs seemed to be small in the clinical setting.

Comparative StudyComparison of the effects of sevoflurane and isoflurane anesthesia on the maternal-fetal unit in sheep.
The aim of this study was to determine the hemodynamic and blood gas effects of inhalational anesthetics on the maternal-fetal sheep unit. The principal hypothesis, tested in chronically instrumented near-term pregnant ewes, was that sevoflurane anesthesia may be safe and useful for the mother and fetus during pregnancy, compared with isoflurane. ⋯ A "low-dose" concentration (0.5-1.0 MAC) of sevoflurane may be safe and useful for both mother and fetus during near-term pregnancy. However, a high concentration (1.5-2.0 MAC) of sevoflurane or isoflurane may induce hemodynamic instability in the mother and fetus when administered.

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.

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.

For direct laryngoscopy, we compared midline and left-molar approaches with respect to ease of intubation, using a Macintosh blade. We investigated the relationship between failure of the left-molar approach and preoperative risk factors for difficult intubation. ⋯ Difficulty in the insertion of the endotracheal tube limits the efficacy of the left-molar approach. It is not possible to predict the failure of intubation with the left-molar approach by considering the preoperative risk factors.
