Randomized Controlled Trial Comparative StudyComparison of the effects of fentanyl, remifentanil, and dexmedetomidine on neuromuscular blockade.
The aim of our study was to compare the effects of fentanyl, remifentanil, and dexmedetomidine on neuromuscular blockade under sevoflurane anesthesia. ⋯ Dexmedetomidine infusion increased the duration of neuromuscular blockade with vecuronium during general anesthesia. In addition to analgesic and sedative effects, dexmedetomidine may enhance the duration of neuromuscular blockade and may be used as an adjuvant anesthetic during general anesthesia.

Case ReportsHypothermic cardiopulmonary bypass for minimally invasive mitral valve plasty in adult moyamoya disease.
A 43-year-old man underwent minimally invasive mitral valve plasty of a flail mitral valve. Four years previously, he had been diagnosed with moyamoya disease (MMD) by cerebral magnetic resonance imaging/angiography findings. ⋯ However, hypothermia during CPB can decrease cerebral oxygen consumption and have a cerebral protective effect. We performed a minimally invasive mitral valve plasty, using hypothermic CPB, in a patient with MMD, without any neurological deficits.

Randomized Controlled TrialEpidrum(®): a new device to identify the epidural space with an epidural Tuohy needle.
Epidrum(®) is an optimal pressure, loss of resistance device for identifying the epidural space. We investigated the usefulness of Epidrum versus the loss of resistance or hanging drop techniques while performing epidural anesthesia. Eighty adult patients who were scheduled for elective surgery under lumbar epidural anesthesia were randomized into two groups. ⋯ The time required to perform epidural anesthesia was significantly shorter in the Epidrum group than in the control group [28 s (10-76) vs. 90 s (34-185); median (interquartile range)] (p < 0.05). Tuohy needle control was significantly easier in the Epidrum group than in the control group (p < 0.05). Epidrum is useful for performing epidural anesthesia quickly while obtaining good Tuohy needle control.

Randomized Controlled TrialUtility of longitudinal paramedian view of ultrasound imaging for middle thoracic epidural anesthesia in children.
The risk of nerve injury for pediatric thoracic epidural block increases stress for anesthesiologists. The purpose of this study was to investigate the usefulness of longitudinal ultrasound imaging for thoracic epidural block (T5-T6 or T6-T7) in anesthetized children scheduled for the Nuss procedure. ⋯ We concluded that longitudinal paramedian ultrasound imaging could reduce performance time and the difficulty for anesthesiologists during epidural block.
