Multiple-deep-breath inhalation induction with 5% sevoflurane and 67% nitrous oxide: comparison with intravenous injection of propofol.
To evaluate the clinical characteristics of multiple-deep-breath inhalation induction with sevoflurane and nitrous oxide followed by the same inhalational anesthetics for maintenance, we compared the technique with intravenous propofol anesthesia. ⋯ Multiple-deep-breath inhalation induction with 5% sevoflurane and 67% nitrous oxide followed by the same inhalational anesthetics for maintenance was safely performed without serious adverse events. However, the induction time was shorter and patient satisfaction was higher in propofol group than in the inhalational group.

Prevention and treatment of malignant hyperthermia in certified training hospitals in Japan: a questionnaire.
To assess the preparedness of hospitals in Japan for cases of malignant hyperthermia (MH). ⋯ The results of the survey revealed that some hospitals had inadequate monitoring methods and a lack of prepared dantrolene for cases of MH under general anesthesia. We recommend that essential monitors be deployed and adequate preparations of dantrolene be maintained for effective early diagnosis and treatment of MH.

Randomized Controlled Trial Clinical TrialComparative effect of 6% hydroxyethyl starch (containing 1% dextrose) and lactated Ringer's solution for cesarean section under spinal anesthesia.
This study aimed to compare low-molecular weight hydroxyethyl starch containing 1% dextrose (HES) infusion and lactated Ringer's solution (LR) in the prevention of hypotension associated with spinal anesthesia for cesarean section. ⋯ This study did not show an advantage of HES compared with LR in the prevention of hypotension or in the reduction of ephedrine dose during cesarean section under spinal anesthesia. The anesthesia level, rather than the choice of intravenous fluid solution, might be related to the ephedrine dose.

This study was conducted to compare the fluid warming capabilities at different flow rates in four different warming systems. ⋯ It is important to choose a warmer according to its characteristics as well as its performance.

Randomized Controlled Trial Clinical TrialComparison of heart rate changes after neostigmine-atropine administration during recovery from propofol-N2O and isoflurane-N2O anesthesia.
Propofol augments the reduction of heart rate (HR) in combination with cholinergic agents and attenuates the HR response to atropine. We examined whether propofol anesthesia was associated with an increased incidence and extent of bradycardia after neostigmine-atropine administration compared with the effects of isoflurane anesthesia. ⋯ We conclude that propofol anesthesia attenuates the initial increases in HR, enhances the subsequent decreases in HR, and increases the incidence of bradycardia after neostigmine-atropine injections compared with the effects of isoflurane anesthesia.
