Mannitol increases cerebral arteriovenous oxygen difference in patients undergoing craniotomy.
Monitoring the jugular venous oxygen saturation (SjVO2) and cerebral arteriovenous oxygen difference (AVDO2) is valuable in detecting cerebral ischemia. In the present study, we investigated the effect of mannitol on SjVO2 and AVDO2 in patients undergoing craniotomy. ⋯ Mannitol may produce a further reduction in SjVO2 accompanied by an increase in AVDO2, suggesting a reduction of cerebral blood flow (CBF) during hyperventilation. Therefore, it should be given cautiously in neurosurgical patients under hyperventilation.

[The blood pressure of upper and lower extremities in parturients under spinal anesthesia for cesarean section].
In clinical practice, we only measure the blood pressure of the arm during cesarean section. However, it can not accurately reflect the real image of pressure of the lower extremity in labor women. Therefore, we recorded simultaneously the arm and leg blood pressure in the term parturients undergoing cesarean section under spinal anesthesia. ⋯ We suggest that monitoring blood pressure in cesarean section under spinal anesthesia should be minute to minute for the first ten minutes and one had best monitor the lower extremity blood pressure in order to promptly detect hypotension.

Review Case Reports[Arytenoid subluxation following endotracheal intubation--a case report].
A previously healthy 39-yr-old man was scheduled for exploratory laparotomy due to acute abdomen. There was no sign of difficult intubation. After induction of anesthesia with thiopental and succinylcholine, the trachea was easily intubated with a 7.0 mm cuffed endotracheal tube. ⋯ Abnormal mobility of vocal cord, edema over arytenoid area found by indirect laryngoscopy should suggest the complication. Further confirmation is then needed. Although the result of our case is good, the reduction should ideally be done within 24-48 h after the incidence to avoid unfavorable long-term sequelae.

Randomized Controlled Trial Clinical Trial[The thermoregulatory threshold during surgery with propofol-nitrous oxide anaesthesia].
Thermoregulatory responses are thought to be drastically suppressed by general anesthesia. In previous studies, it was shown that halothane, isoflurane and fentanyl-N2O combination decrease the threshold of vasoconstriction in general anesthesia. Propofol is a recently introduced intravenous anesthetic. The thermoregulatory threshold of its administration during surgery has not been quantified. ⋯ General anesthesia with propofol/N2O during surgery drastically inhibits thermoregulatory vasoconstriction. This effect should also be noted during long-term use of propofol (e.g. ICU-sedation).

Use of a single lumen endotracheal tube and continuous CO2 insufflation in transthoracic endoscopic sympathectomy.
Transthoracic endoscopic sympathectomy (TES) is an accepted standard surgical treatment for palmar hyperhidrosis. For anesthetic management, a double lumen endobronchial tube is usually used to deflate the lung on the operative side. Recently we have applied continuous insufflation of carbon dioxide (CO2) into the pleural cavity to merely compress one lung while ventilating both lungs with a conventional single lumen endotracheal tube. ⋯ It is concluded that the use of single lumen endotracheal tube with continuous insufflation of CO2 in TES is easy, simple and safe.
