Randomized Controlled Trial Comparative Study
[Comparison of the Laryngeal Tube Suction and the Proseal laryngeal Mask Airway in anesthetized patients].
The Laryngeal Tube Suction (LTS : Smith Medical, Tokyo) is a new laryngeal tube that has an additional channel for gastric tube placement. Similarly, the Proseal Laryngeal Mask Airway (PLMA) also has a drain tube for gastric tube placement. This study compared the functions of these two devices. ⋯ With respect to clinical function, the LTS and PLMA were similar and either device can be used to establish an effective airway in anesthetized patients.

Randomized Controlled Trial Comparative Study
[Use of gum elastic bougie for tracheal intubation: comparison of different tracheal tubes].
Gum elastic bougie (GEB) is one of the most useful devices for patients whose tracheas are difficult to intubate during anesthetic induction. But no previous study has evaluated the effects of the types of the tracheal tube. We hypothesized that wire-reinforced tracheal tubes were superior to standard tracheal tubes in the success rate of tracheal intubation when using GEB. We compared these two different types of tracheal tubes in using GEB. ⋯ The type of tracheal tube would not affect the success rate and time of intubation when using gum elastic bougie.

Randomized Controlled Trial
[Cardiac anesthesia induction by low target plasma concentration setting of propofol using target-controlled infusion].
Propofol-anesthesia administerd using target-controlled infusion (TCI) has been proposed for cardiac surgery. But, moderate target concentration of propofol during induction using TCI has not been studied in detail. ⋯ We have demonstrated that propofol TCI at a target concentration of 1.5 microg x ml(-1) is effective for hemodynamic stability during induction of anesthesia in patients for cardiac surgery under CPB.

Randomized Controlled Trial Comparative Study
[Postoperative management of carotid endarterectomy with dexmedetomidine--a comparison with propofol].
We compared dexmedetomidine (DEX) with propofol (PRO) in patients requiring sedation after carotid endarterectomy (CEA) in the intensive care unit (ICU). Incidence of hyperperfusion syndrome, the sedative and analgesic properties, cardiovascular responses, and ventilation characteristics were discussed. ⋯ DEX is a safe and acceptable sedative agent for patients requiring sedation after CEA in the ICU; however, further studies are needed to assess the appropriate sedative doses of DEX.

Randomized Controlled Trial
[Optimal dose of fentanyl for postoperative epidural analgesia after thoracic surgery].
We investigated the dose of fentanyl in ropivacaine for epidural anesthesia that will provide effective analgesia with minimal side effects after thoracic surgery. ⋯ We conclude that continuous epidural administration of more than 15 microg x hr(-1) of fentanyl in ropivacaine provides pain relief and few side effects after thoracic surgery.
