Case ReportsIsolated bilateral paralysis of the hypoglossal and recurrent laryngeal nerves (Bilateral Tapia's syndrome) after transoral intubation for general anesthesia.
Tapia's syndrome is due to extracranial involvement of the hypoglossal nerve and the recurrent laryngeal branch of the vagal nerve. The injury of these nerves is a rare complication of anesthetic airway management. ⋯ Forty-eight hours later, the movements of the vocal cords started to recover and full recovery was achieved by the fourth day. Within 3 days, tongue mobility was gradually improved and the patient's symptoms resolved completely by 4 weeks.

Randomized Controlled Trial Clinical TrialInfluence of the injection site (L2/3 or L3/4) and the posture of the vertebral column on selective spinal anesthesia for ambulatory knee arthroscopy.
We tested the hypothesis that selective spinal anesthesia for ambulatory knee arthroscopy can be accomplished with a small dose of bupivacaine at the L3/4 interspace with or without a head-down tilt of 5 degrees when the patients were in the lateral decubitus position. ⋯ When producing selective spinal anesthesia, the posture of the vertebral column is a major determinant of both sensory and motor segments to be blocked. A 4-mg dose of hyperbaric bupivacaine at the L3/4 interspace with a 5 degrees head-down tilt of the vertebral column for 6 min is recommended for knee arthroscopy.

Case ReportsGuided tactile probing: a modified blind orotracheal intubation technique for the problem-oriented difficult airway.
We present 'tactile probing', a guided approach to blind orotracheal intubation to secure a problem-oriented anticipated difficult airway in a 55-year-old male patient scheduled for elective surgical tracheostomy for a postradiotherapy translaryngeal carcinoma. Standard techniques to gain the airway were inapplicable in this case and awake flexible fiberoscopy-aided intubation had already failed.

Randomized Controlled Trial Comparative Study Clinical TrialCerebral blood flow velocity increases when propofol is changed to desflurane, but not when isoflurane is changed to desflurane in children.
Children may exhibit delayed emergence following maintenance of anesthesia with propofol or isoflurane. Desflurane is often used towards the end of procedures to facilitate emergence. This study evaluated the effect on middle cerebral artery blood flow velocity (Vmca) in anesthetized children when propofol or isoflurane was substituted with desflurane. ⋯ When propofol is changed to desflurane, cerebral blood flow velocity increases significantly in normal children. This cerebral vasodilatory effect may have important implications in the neurosurgical setting.

Randomized Controlled Trial Clinical TrialPentoxifylline attenuates the increase in whole blood viscosity after transfusion.
Pentoxifylline improves tissue oxygenation and intestinal blood flow in models of haemorrhagic shock, and it has been used for the treatment of intermittent claudication due to its beneficial effects on haemorheology. We investigated the effects of pentoxifylline on whole blood viscosity during packed red-blood cell transfusion in critically ill adult patients. ⋯ These results suggest that pentoxifylline is effective in attenuating the increase in whole blood viscosity after a transfusion of packed red-blood cells. Plasma viscosity is not influenced by pentoxifylline.
