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 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.

Randomized Controlled TrialCaudal bupivacaine supplemented with morphine or clonidine, or supplemented with morphine plus clonidine in children undergoing infra-umbilical urological and genital procedures: a prospective, randomized and double-blind study.
We aimed to evaluate postoperative analgesia of morphine, or clonidine, or morphine plus clonidine, added to caudal bupivacaine in children undergoing infra-umbilical urological and genital procedures. ⋯ To conclude, we showed that 20 μg/kg of morphine added to caudal bupivacaine 0.166% plus epinephrine 1:600,000 decreased the use of analgesics in the postoperative period, although it was associated with an increased incidence of PONV. However, the addition of clonidine (1.0 μg/kg) to caudal bupivacaine provided no additional clinical benefit over bupivacaine alone.

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.

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.
