The preventative effect of ramosetron on postoperative nausea and vomiting after total thyroidectomy.
Postoperative nausea and vomiting (PONV) frequently develops in patients undergoing thyroidectomy, and propofol-based total intravenous anesthesia (TIVA) has been reported to reduce the incidence of PONV. The present study was undertaken to compare the effects of ramosetron on PONV in women following total thyroidectomy under TIVA. ⋯ Ramosetron was found to be effective at reducing the incidence and severity of postoperative nausea in women that underwent total thyroidectomy with propofol-based TIVA, especially during the first 6 hours postoperatively.

The proper effect site concentration of remifentanil for prevention of myoclonus after etomidate injection.
Etomidate frequently induces myoclonus when administered intravenously with bolus injection during anesthetic induction. This can be bothersome for the anesthesiologist. The dose of remifentanil appropriate for preventing myoclonus without side effects was investigated. ⋯ Administration with a 2 ng/ml effect site concentration of remifentanil could reduce the incidence of myoclonus caused by etomidate bolus injection without chest wall rigidity.

The effect of remifentanil versus N(2)O on postoperative pain and emergence agitation after pediatric tonsillectomy/adenoidectomy.
Remifentanil can be an alternative to N(2)O in general anesthesia. Intraoperative remifentanil may lead to acute opioid tolerance. This study aims to assess the effect of remifentanil substituted for 70% N(2)O on postoperative pain in children undergoing tonsillectomy/adenoidectomy. In addition, we evaluated the effect of remifentanil infusion on incidence of emergence agitation in these patients. ⋯ In children undergoing tonsillectomy/adenoidectomy, intraoperative remifentanil infusion may increase incidence of severe postoperative pain compared to N(2)O, but it may not affect incidence of emergence agitation.

How should we monitor pediatric patients with Duchenne muscular dystrophy? -A case report-.
Duchenne muscular dystrophy is a hereditary disorder characterized by progressive muscle weakness and contracture, and special care during anesthesia is needed in these patients. Because inhalational anesthetics and succinylcholine can cause fatal results, intravenous anesthetics are commonly used. However, monitorings for the pediatric population are not otherwise specified. ⋯ He was monitored with bispectral index (BIS), acceleromyography (TOF). At the end of surgery, recovery of TOF ratio to 90% was evaluated, followed by injection of pyridostigmine and glycopyrrolate. When reversal of neuromuscular block was confirmed quantitatively and clinically, the patient was extubated and he experienced no complication.

The effect-site concentration of propofol producing respiratory depression during spinal anesthesia.
Propofol is used worldwide for its sedative effective; nonetheless, has the serious side effect of respiratory depression. An increased blood concentration of propofol is well known to be associated with increased respiratory depression. However, there are no studies of the effect site concentration inducing respiratory depression. The purpose of this study was to determine the effect site concentration inducing respiratory depression of propofol when sedating a patient after spinal anesthesia. ⋯ The EC(5), EC(10), and EC(50) of effect site propofol for respiratory depression during spinal anesthesia were 3.09 mcg/ml ,3.18 mcg/ml, and 3.99 mcg/ml, respectively.
