Randomized Controlled Trial Comparative StudyCore temperatures during major abdominal surgery in patients warmed with new circulating-water garment, forced-air warming, or carbon-fiber resistive-heating system.
It has been reported that recently developed circulating-water garments transfer more heat than a forced-air warming system. The authors evaluated the hypothesis that circulating-water leg wraps combined with a water mattress better maintain intraoperative core temperature ≥36°C than either forced-air warming or carbon-fiber resistive heating during major abdominal surgery. ⋯ The combination of circulating-water leg wraps and a mattress better maintain intraoperative core temperature than did forced-air and carbon-fiber warming systems.

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.

Letter Case ReportsTotal spinal block after spinal anesthesia following ongoing epidural analgesia for cesarean delivery.
There may still be an increased risk of total spinal block up to 90 minutes after the last epidural bolus.

Randomized Controlled TrialComparison between propofol and dexmedetomidine in postoperative sedation after extensive cervical spine surgery.
Patients undergoing extensive cervical spine surgery (ECSS) occasionally require emergency reintubation due to postoperative airway complications. To avoid it, an endotracheal tube is retained in patients maintained under sedation overnight. This study was conducted to determine whether dexmedetomidine would be superior in sedative effects to propofol for postoperative sedation after ECSS. ⋯ Both sedatives are efficacious after ECSS; however, dexmedetomidine decreased heart rate and required higher dose of dopamine.
