Randomized Controlled Trial Comparative Study Clinical Trial
[A randomized double-blind comparison of epidural versus intravenous tramadol infusion for postoperative analgesia].
This study compared epidural and intravenous tramadol infusions for postoperative analgesia after gastrectomy. ⋯ We conclude that intravenous tramadol infusion provides effective and safe postoperative analgesia. A futher examination is required for the suitable dose of tramadol in epidural infusion.

Randomized Controlled Trial Clinical Trial
[Effects of landiolol on cardiovascular responses, bispectral index and body movement during endotracheal intubation].
We investigated the effects of a novel highly cardioselective short-acting beta-blocker, landiolol, on cardiovascular response, bispectral index and body movement during endotracheal ⋯ Our results suggest that landiolol infusion was effective to attenuate the hemodynamic, arousal and somatic responses to endotracheal intubation.

Comparative Study
[Which anesthetic technique is more suitable for hip fracture surgery in patients above the age of 85, spinal or epidural?].
Anesthesia for hip fracture in elderly patients is a challenge because of their reduced functional reserve. We compared spinal and epidural anesthesia retrospectively in the operations of hip fracture in patients above the age of 85. ⋯ Spinal anesthesia is preferable for the operation for hip fracture compared with epidural anesthesia, because of fewer failed cases and smaller decreases of blood pressure.

Comparative Study
[Efficacy of continuous subcutaneous pentazocine infusion for the postoperative analgesia in lower abdominal surgery].
Continuous subcutaneous infusion (CSI) of analgesics may be an alternative for pain control in patients without an epidural catheter. The aim of this study was to investigate the efficacy of CSI using pentazocine in lower abdominal surgery with inhalation anesthesia or with total intravenous anesthesia. ⋯ In patients undergoing lower abdominal surgery, CSI of pentazocine provided effective postoperative pain relief and effectiveness did not depend on anesthetics during anesthesia.

Case Reports
[Bilateral recurrent laryngeal nerve paralysis in a child following a neurosurgical operation].
We experienced a case of 7-year-old boy who developed bilateral recurrent laryngeal nerve paralysis following an elective neurosurgical operation under oxygen-nitrous oxide-isoflurane anesthesia. He underwent a removal of brain tumor in the supratentorial region on supine position. After the removal of the endotracheal tube in the intensive care unit, he developed marked respiratory effort and inspiratory stridor. ⋯ In the present case, an endotracheal tube, a transesophageal stethoscope and a nasogastric tube inserted into the narrow laryngeal space might have been a cause of this complication. Moreover, accidental extreme flexion of his neck which occurred during the surgery might also be an additional cause. This case suggests that recurrent laryngeal nerve paralysis due to anesthetic instruments around the larynx is a possible cause of complications during general anesthesia in pediatric patients.
