Randomized Controlled Trial Comparative Study Clinical Trial
[Propofol and sevoflurane--a comparison of anesthesia for laryngomicrosurgery].
Laryngomicrosurgery has some special characteristics. It is under much stress such as intubation and direct laryngoscopy during a short operation time. Therefore both adequate anesthesia and quick recovery are needed. ⋯ The emergence time was significantly shorter in Group P than in Group S. The state of recovery was much better in Group P compared with Group S in both 5 minutes after extubation and 5 minutes after entering the recovery room. Therefore, anesthesia with propofol and small dose of fentanyl at induction is more adequate compared with anesthesia with sevoflurane in laryngomicrosurgery.

Randomized Controlled Trial Comparative Study Clinical Trial
[Comparison of transarterial technique and paresthesia technique of axillary brachial plexus block].
Axillary brachial plexus blocks were established in 40 patients using transarterial technique (n = 20) or paresthesia technique (n = 20). Sensory and motor blockades of nerves supplying the upper extremity were compared at 10, 20 and 30 minutes after the injection of local anesthetics (1.5% plain mepivacaine 40 ml). Sensory blockades of the radial nerve and axillary nerve were significantly higher with transarterial technique than paresthesia technique. ⋯ Proximal and distal spreads of the local anesthetic-contrast medium mixture within the axillary neurovascular sheath were studied in 20 patients. No statistically significant difference was observed in the spread of contrast agent between the two techniques. Transarterial technique is a recommendable method for hand surgery and especially indicated for the surgery of the area supplied by the radial nerve.
