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.

Recently, in addition to bronchofiberscope, the new equipments to manage difficult intubation are available. However, it is unknown whether the incidence of difficult intubation decreases or not. In order to determine the incidence of severe difficult intubation, we conducted a survey of patients who presented with severely difficult intubation during 2005-2010. ⋯ The incidence of severely difficult intubation was 0.3% in Hokkaido university hospital during 2005-2010.

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.

Hypotension is a common adverse effect of spinal anesthesia (SA). Preoperative fluid infusion is recommended to prevent hypotension during caesarean section. The aim of this study is to document relationship between preoperative total body water (TBW) and the amount of the vasopressors given intraoperatively and to evaluate the change of maternal body water composition (BWC). ⋯ Preoperative TBW does not affect the amount of vasopressors given during caesarean section, which suggested massive fluid infusion can not always prevent hypotension after SA. A slight changes in TBW and ECW may be induced by SA, while the exact physiological and clinical significance of these observation remains to be elucidated.
