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.

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 ReportsHyperkalemia during surgery: is it an early warning of propofol infusion syndrome?
We present a case of severe hyperkalemia in a 48-year-old man after short-term infusion of an average dose of propofol. We suspected that the hyperkalemia in this patient was a sign of propofol infusion syndrome. ⋯ There were no other evident causes of hyperkalemia as documented by laboratory data. The procedure was abandoned and the patient was taken to postoperative recovery, where his potassium levels returned to normal at the end of 10 h.

Randomized Controlled TrialEffects of landiolol, a short-acting beta-1 blocker, on hemodynamic variables during emergence from anesthesia and tracheal extubation in elderly patients with and without hypertension.
Tracheal extubation and emergence procedures induce abrupt changes in hemodynamics and humoral responses. We conducted a prospective randomized study to examine the effects of the short-acting beta-1 blocker, landiolol, on hemodynamics during emergence from anesthesia in elderly patients with and without hypertension. ⋯ This study indicates that the use of a landiolol infusion for preventing hemodynamic instability in elderly patients during the emergence period would be dependent on the presence or absence of hypertension in these patients.

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.
