GlideScope Cobalt video laryngoscope is a new type of GlideScope series. A reusable camera baton is inserted into a disposable plastic curved blade. The blade has 5 choices of size and can be used from infants to adults. The aim of the current study was to evaluate the efficacy of GlideScope Cobalt in children. ⋯ GlideScope Cobalt is a useful tool in chidlren's airway management but it necessitates getting used to the tracheal tube maneuver and lacks the suitable blade size for 6-8 years old children.

The i-gel is a relatively new supraglottic airway, which has been shown to be useful during general anesthesia, and it may have a potential role during cardiopulmonary resuscitation. In a manikin study, we have found that, compared with laryngeal mask airways, the i-gel was significantly easier and faster to insert, due mainly to no-necessity of cuff inflation. ⋯ The pack includes the i-gel O2 (which has a side port for oxygen delivery), a suction catheter, a sachet containing lubrication jelly, and a fixation strap. We describe the role of the i-gel during emergency airway management.

Case Reports
[Anesthetic management for removal of a giant ovarian tumor using FloTrac x Vigileo monitoring system].
We successfully managed anesthesia in a patient with a giant ovarian tumor weighting 22 kg, using FloTrac x Vigileo monitoring system. A 43-year-old woman (67.2 kg, 154.5 cm and abdominal girth 111.3 cm) was admitted for removal of a giant ovarian tumor. Arterial blood pressure (ABP), heart rate, percutaneous arterial oxygen saturation, cardiac index (CI) and stroke volume variation (SVV) were monitored. ⋯ Therefore, we did not increase fluid administration rate to avoid excessive hydration. After tracheal extubation, respiratory and hemodynamic states were stable, and the patient had no postoperative complication. We conclude that FloTrac x Vigileo System is useful for monitoring cardiac performance parameters, and helps anesthesiologists adjust drainage speed of the content and infusion rate to maintain the stability of circulatory state, in removal of a giant cyst.

Randomized Controlled Trial
[Efficacy and safety of remifentanil-based regimen for postoperative pain management in abdominal surgery patients: a double-blind study with low-dose remifentanil infusion of 0.02 microg x kg(-1) x min(-1)].
Remifentanil is a powerful analgesic with fast onset and ultra-short duration of action. Its context-sensitive half-time is consistently short even after a prolonged infusion. Remifentanil is effective for providing better postoperative analgesia, but this method is not generally accepted in Japan. The present study was conducted to document efficacy and safety of low-dose remifentanil infusion in postoperative patients. ⋯ Remifentanil infusion at 0.02 microg x kg(-1) x min(-1) can safely be used without any serious adverse events, while it may not be enough for postoperative analgesia. The best dosage of this drug for postoperative analgesia remains to be elucidated.

Randomized Controlled Trial
[Effect of concentration on counting numbers on pain induced by injection of propofol].
One of the concerns in the use of propofol is the pain on injection of the drug. Many attempts were made to prevent such pain, none of which has been reasonably successful. We hypothesized that the pain is attenuated when the patient is directed to concentrate on counting numbers while propofol is injected. ⋯ Intensive counting did not reduce the incidence of pain on injection of propofol. Age and the degree of pain on inserting intravenous cannula can be a useful predictor for an intolerable pain on injection of propofol.
