Postoperative delirium increases the morbidity and mortality in elderly patients. The present study was carried out to evaluate whether the difference of anesthetics has influence on the incidence of postoperative delirium, retrospectively. ⋯ Propofol anesthesia decreases postoperative delirium in elderly patients compared with sevoflurane anesthesia.

A morbidly obese patient, with a body mass index of 43 kg m(-2), was scheduled to undergo open reduction and internal fixation (ORIF) to his left fibular fracture under general anesthesia in the lateral position. Before the induction of general anesthesia the patient positioned himself comfortably in right lateral. General anesthesia was induced with intravenous propofol and remifentanil infusions. ⋯ As soon as he awoke, LMA was removed in the lateral position. The patient turned to the supine position himself and was discharged to general ward. We consider our method, the induction of general anesthesia and the LMA insertion in the lateral position, was a selectable option to a morbidly obese patient who underwent an operation in the lateral position.

Effect of epidural anesthesia is affected by catheter tip position. Migration of an epidural catheter is known and several methods were reported to secure fixation of the catheter, but there were no gold standard method to fix it. ⋯ We conclude that fixation of epidural catheter by only Tegaderm can not be a gold standard even if circular loop and record label are used.

Preoperative fasting period is required in order to reducing the risk of pulmonary aspiration which may occur during pediatric general anesthesia. Overnight fasting is still prevalent in Japan. ⋯ Cochrane Database evaluated this guideline twice in 2005 and in 2009. In this article, recent tactics of preoperative fasting in children is reviewed along the ASA guideline and the Cochrane report.

Recently, European countries and US have issued the practice guidelines for preoperative fasting, and there is a trend of shortening the fating time before surgery. In Japan, some institutions have just started to use an oral rehydration therapy by oral rehydration solutions, which is effective in the treatment of mild to moderate dehydration, and in the preoperative water and electrolyte management. Besides shortening the fasting time, water and electrolytes can be adequately given to the patients by oral rehydration therapy Currently, this therapy is gaining a widespread attention, because it can improve patients' satisfaction for preoperative care and is also a safe and efficient medical treatment.
