Case Reports
[A case of endotracheal intubation in prone position utilizing PENTAX-Airwayscope for morbidly obese patient].
We experienced the airway management of a morbidly obese patient in prone position utilizing PENTAX-Airwayscope (AWS) which is a novel airway device for endotracheal intubation. A 29-year-old man, who was 150 kg in weight and 51.9 kg x m(-2) in body mass index, was scheduled for the discectomy for lumbar disc herniation. After the topical anesthesia with lidocaine spray, the patient lay on his stomach by himself on the table. ⋯ With the patient breathing spontaneously, we successfully inserted the reinforced endotracheal tube. After the maintenance of anesthesia with continuous infusion of dexmedetomidine, ketamin and remifentanil, the patient awoke clearly without pain and endotracheal tube was removed safely in the prone position. Although the prone position is not the standard position for endotracheal intubation under general anesthesia, our technique could be performed in emergency situations.

Comparative Study
[How to improve positioning of the head--the sniffing position, considered to be suitable for endotracheal intubation].
The sniffing position, a combination of flexion of the neck and extension of the head, is considered to be suitable for the performance of endotracheal intubation. To place a patient in this position, anesthesiologists usually put a pillow under a patient's occiput. However, with a regular pillow, the resulting extension of the head tends to be suboptimal. ⋯ The triangular pillow improves the laryngoscopic view and facilitates endotracheal intubation by optimizing a patient's head position.

Case Reports
[A case of bilateral recurrent laryngeal nerve palsy after thyroid surgery under intraoperative nerve monitoring].
A 66-year-old woman suffering from Basedow disease had total thyroidectomy under intraoperative monitoring (IOM) of recurrent laryngeal nerve (RLN) using Medtronic Xomed Nerve Integrity Monitor-2 (Medotronic, Mineapolice, Minesota, USA). IOM indicated a positive signal for her right RLN while the signal for her left RLN disappeared during the operation. During the surgery, surgeons identified her left RLN which was anatomically intact. ⋯ On POD3, dysfunction of her vocal cord continued, therefore, she had tracheotomy With long-term follow up, her vocal cord function returned to normal on POD37 and tracheotomy tube was removed. In conclusion, positive signals of IOM are not always correlated with proper function of vocal cord. Therefore, respiratory condition should be carefully observed during postoperative period.

Enhanced recovery after surgery (ERAS) protocols aim to improve patient care, reducing complication rates, and shortening hospital stay following colorectal surgery in Europe. In cooperation with colorectal surgeons, ERAS protocols were initially introduced in our hospital to the patients undergoing open colorectal resection in July 2010. ⋯ We, anesthesiologists as perioperative physicians, can improve key elements of perioperative care such as patients' counseling, perioperative analgesia and early mobilization by collaboration with surgeons and nurses, to facilitate postoperative recovery.

Randomized Controlled Trial
[Breakdown of fat tissue and muscle protein under remifentanil anesthesia].
We investigated the efficacy of glucose infusion for the inhibition of breakdown of fat tissue and muscle protein under remifentanil anesthesia. ⋯ Infusion of glucose suppresses breakdown of fat tissue and muscle protein under remifentanil anesthesia.
