BACKGROUND: Midazolam has been widely studied for preventing emergence agitation. The authors previously reported that in children with sevoflurane anesthesia, intravenous administration of midazolam (0.05 mg/kg) before the end of surgery reduced the incidence of emergence agitation but prolonged the emergence time. This study was designed to test the hypothesis that a lower midazolam dose could suppress emergence agitation with minimal disturbance of the emergence time in children with sevoflur

Members of the colony stimulating factor cytokine family play important roles in macrophage activation and recruitment to inflammatory lesions. Among them, granulocyte-macrophage colony stimulating factor (GM-CSF) is known to be associated with immune response to mycobacterial infection. However, the mechanism through which Mycobacterium tuberculosis (MTB) affects the expression of GM-CSF is poorly understood. Using PMA-differentiated THP-1 cells, we found that MTB infection increased GM-CSF mRN

Purpose: Prolonged duration of cardiopulmonary bypass aggravates the degree of inflammation and coagulopathy. We investigated the influence of 6% hydroxyethylstarch (HES) 130/0.4 on coagulation and inflammation compared with albumin when used for both cardiopulmonary bypass priming and perioperative fluid therapyin patients undergoing complex valvular heart surgery. Materials and Methods:Fifty four patients were randomly allocated into albumin-HES, albumin-nonHES,and HES-HES groups. The cardiopu

When local anesthetics are used, the administration of dexmedetomidine (DEX) can prolong analgesic duration. However, the effect of caudal DEX on high volume/low concentration (HVLC) local anesthetics has not been studied. We investigated the analgesic effect of DEX added to a HVLC of ropivacaine for caudal block in children. Eighty children (the American Society of Anesthesiologists (ASA) status I; age, 1-6 years) undergoing ambulatory orchiopexy were enrolled in the study. Children were random

OBJECTIVES/HYPOTHESIS: Laser microlaryngeal surgery (LMS) is a short operation requiring brief and intense paralysis. Adequate muscle relaxation and rapid recovery of neuromuscular function are essential for improving surgical conditions and reducing the incidence of complications during LMS. However, the ideal muscle relaxant with a rapid onset and short duration of action is not yet available. Rocuronium has rapid onset at higher doses, but with a prolonged duration of action. Sugammadex is a

There were statistical differences in the provision of humidity among different anesthesia workstations. The Cato and Primus workstations were superior to Excel and Avance. However, even these were unsatisfactory in humans. Therefore, additional devices that provide inspired gases with adequate heat and humidity are needed for those undergoing general anesthetic procedures.

Background For patients undergoing endoscopic sinus surgery, intranasal injection of epinephrine can cause acute increases in heart rate and blood pressure. Objective Among the drugs for reducing hyperdynamic effects, dexmedetomidine and remifentanil are expected to blunt the acute hemodynamic responses after intranasal injection of epinephrine. Our study compared a difference in the 2 drugs in their abilities to blunt the hemodynamic responses in intraoperative period and postoperative profile.

OBJECTIVE: General anaesthesia with tracheal intubation results in sore throat. We evaluated the influence of the two-handed jaw thrust on postoperative sore throat in patients who require tracheal intubation. METHODS: In this prospective, double-blind, single-centre, parallel-arm, and randomised trial, 92 patients who were scheduled for general anaesthesia for total hip arthroplasty were allocated to one of two groups. In the jaw thrust group (n = 46), the two-handed jaw thrust manoeuvre was ap
