Randomized Controlled Trial[Application of sedation with a low dose of dexmedetomidine during intrathecal anesthesia in elderly patients].
To explore the feasibility and safety of sedation with a low dose of dexmedetomidine (DEX) during intrathecal anesthesia in the elderly patients. ⋯ Sedation with a small dose of DEX during intrathecal anesthesia in elderly patients is both feasible and efficacious. But studies of larger sample sizes are warranted to confirm its safety.

Randomized Controlled Trial[Evaluation of safety and anesthetic effect for ultrasound-guided cervical plexus block].
To observe the influences upon the degree of diaphragmatic excursion during deep cervical plexus block at the third cervical vertebra (C3) and compare the safety and anesthetic effect of modified cervical plexus block by ultrasonic guidance and blocking of cervical plexus at one point. ⋯ The improving effect of ultrasound-guided cervical plexus block upon the degree of diaphragmatic movement is within the compensatory range of body. In comparison with the traditional one-point blocking of cervical plexus, the modified cervical plexus block with ultrasonic guidance offers better anesthetic effects, fewer complications and convenient anesthetic localization. Thus it may be clinically applicable.
