Randomized Controlled Trial
[The Effect of Preoperative Oral Rehydration on Hemodynamic Changes during Induction of Anesthesia and Intraoperative Fluid Management].
Preoperative oral rehydration solution (ORS) prevents dehydration before surgery. Therefore taking enough ORS possibly reduces the hemodynamic changes during induction of anesthesia, and reduces the amount of fluid needed during anesthesia. ⋯ Preoperative oral rehydration increases circulating blood volume, it keeps high CI during induction of anesthesia, and reduces the amount of intraoperative fluid.

Case Reports
[Desflurane Anesthesia in a Morbidly Obese Patient with Severe Obstructive Sleep Apnea].
A 33-year-old morbidly obese patient (body mass index = 59.5 kg x m(-2)) with severe obstructive sleep apnea was scheduled to undergo osteosynthesis of right radial, ulnar and femoral fractures under general anesthesia. Awake intubation under conscious sedation using fantanyl and midazolam was performed by the Pentax-AWS Airwayscope. ⋯ Respiratory depression was minimal during postoperative period. In this case desflurane was safely used in a morbidly obese patient with severe obstructive sleep apnea.

Comparative Study
[Comparison of Seven Intubation Devices in Difficult Airway Model].
The efficacy in tracheal intubation may differ between different video-optical devices, in particular in patients with difficult airways. The purpose of this study was to evaluate the efficacy of video-laryngoscopes and fiberoptic bronchoscope (FOB) in tracheal intubation on a mannequin with several difficult airways, including limited mouth opening, cervical spine rigidity and tongue edema. ⋯ Videolaryngoscopes can generally be useful in patients with all difficult airways, but may be difficult in some circumstances (such as tongue edema). The FOB provided good laryngeal view in all cases, but the success rate of tracheal intubation was low and the time to intubate trachea was long.

Case Reports
[Two Separate Instances of Anesthetic Management in a Patient Initially Diagnosed with Stiff-person Syndrome].
In this case report, we describe separate instances of general anesthetic management administered to a patient during treatment for two unrelated conditions. The patient, a 57-year-old woman who had been experiencing walking difficulties for about four years, fell down because of muscle rigidity and spasms and fractured her humerus. She was subsequently diagnosed with stiff-person syndrome. ⋯ No prolonged effect of the muscle relaxant or any autonomic reactions were observed. The patient was fully conscious and in good respiratory condition after both surgeries, and was extubated in the operating room. There were no perioperative complications.

Sevoflurane is one of the commonly used volatile anesthetics in cancer patients. The protective effect of sevoflurane preconditioning has raised concerns about whether sevoflurane could act advantageously for survival even of cancer cells. Therefore, we investigated the effects of sevoflurane on proliferation in colon cancer cell lines. ⋯ We had shown that 1% sevoflurane for 6 hr potentially enhances cell proliferation via K(ATP) channels in cancer cells.
