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
[Anesthesia for Patients with Obstructive Sleep Apnea Syndrome Associated with Severe Obesity].
A 41-year-old woman with concomitant severe obesity, obstructive sleep apnea syndrome, and asthma was scheduled for endoscopic cholecystectomy. She was 165.8 cm tall and weighed 141.2 kg, with BMI of 51.4. We were concerned with difficulty in ventilation and intubation at the time of anesthesia induction and intra- and post-operative ventilatory failure. ⋯ Although she received no nerve block, she did not choke at the time of intubation. Because of airway pressure elevation during surgery, volume-controlled ventilation was changed to pressure-controlled ventilation, and, because of a worsening P/F ratio, the recruitment procedure was performed during surgery, with a consequent improvement in the ratio. Although the use of the reservoir and NPPV equipment after extubation was considered, her respiratory status was stable, and she returned to her room with oxygen mask.

The present study was designed to evaluate the postoperative values such as body temperature (BT), white blood cells (WBC), P/F ratio and C-reactive protein (CRP) associated with propofol or sevoflurane in patients undergoing thoracic surgery with one-lung ventilation. ⋯ Propofol and sevoflurane had similar effect on BT, WBC, P/F ratio and CRP in patients undergoing thoracic surgery with one-lung ventilation.

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.
