Randomized Controlled TrialA randomized trial to identify optimal precurarizing dose of rocuronium to avoid precurarization-induced neuromuscular block.
The aim of this study was to examine the safe precurarizing dose of rocuronium required to avoid neuromuscular block after precurarization. ⋯ Rocuronium at 0.06 mg/kg is an overdose for precurarization. The results of the present study demonstrate that a safe and effective precurarizing dose of rocuronium is 0.03 mg/kg.

Randomized Controlled Trial Comparative StudyA randomized comparison of different doses of intrathecal levobupivacaine combined with fentanyl for elective cesarean section: prospective, double-blinded study.
Levobupivacaine may produce a sensory and motor block different from that produced by bupivacaine, which is the most popular local anesthetic in parturients undergoing cesarean section. The aim of this study was to investigate the block characteristics, the clinical efficacy, surgeon and patient satisfaction, and hemodynamic effects of using different doses of intrathecal plain levobupivacaine combined with fentanyl. ⋯ The incidence of hypotension was higher in the levobupivacaine 10 mg group, even though this group presented more effective anesthesia and greater patient and surgeon satisfaction compared with the levobupivacaine 5 and 7.5 mg groups. As a result, we believe that levobupivacaine 7.5 mg combined with fentanyl 15 μg is suitable for combined spinal-epidural anesthesia in elective cesarean section.

Randomized Controlled TrialLow-dose ropivacaine or levobupivacaine walking spinal anesthesia in ambulatory inguinal herniorrhaphy.
The purpose of our study was to compare the equipotent doses of ropivacaine and levobupivacaine for walk-out criteria and the characteristics of spinal anesthesia in inguinal herniorrhaphy surgery. ⋯ We suggest that both local anesthetics can be used in walking spinal technique. Levobupivacaine may be an alternative local anesthetic for walking spinal anesthesia as it provides minimum motor block and a long duration of postoperative analgesia, even if its use is not associated with a shorter home discharge time.

Randomized Controlled TrialOral melatonin, dexmedetomidine, and midazolam for prevention of postoperative agitation in children.
Several studies have reported that sevoflurane was associated with a relatively high incidence of emergence agitation in children even in the absence of any surgical intervention. The aim of this study was to compare early agitation characteristics of oral melatonin, dexmedetomidine, and midazolam premedication in children who were given sevoflurane anesthesia for esophageal dilatation. ⋯ We found that oral melatonin, dexmedetomidine, and midazolam reduced the incidence of emergence agitation in children after sevoflurane anesthesia.

Randomized Controlled Trial Comparative StudyEfficacy of the Airtraq(®) laryngoscope with a fiberoptic bronchoscope compared with that of Airtraq(®) alone for tracheal intubation: a manikin study.
Successful intubation using the Airtraq(®) requires optimal positioning of the glottis in the middle of the viewfinder. If the glottic view cannot be optimized, some glottic manipulation is essential for the Airtraq-assisted successful intubation. We evaluated the efficacy of the combined use of the Airtraq and a fiberoptic bronchoscope (FOB) compared with that of the Airtraq alone for tracheal intubation in simulated airway scenarios. ⋯ The combined use of Airtraq(®) and a FOB enables rapid intubation in simulated difficult airway scenarios compared with intubation using Airtraq alone, and the speed of intubation performed by anesthetists and residents is similar in all airway scenarios.
