简要总结
Ultrasound-guided (USG) brachial plexus (BP) block efficacy at the Supraclavicular (SCL), Lateral- Infraclavicular (LIC) and Axillary (AX) level: Randomized, observer-blinded study of the single-penetration multiple-injection-technique.
详细描述
The investigators will compare the BP block efficacy (for surgical anaesthesia) with the USG single-penetration multiple-injection-technique at the SCL, LIC and AX level for upper-extremity surgery (elbow, forearm, wrist, hand). The investigators want to investigate whether the single-penetration multiple-injection-technique would provide for safe surgical anaesthesia with lower volumes of local anaesthetics than has previously been described in a comparative study at the three different levels.
120 patients will prospectively be randomized to an USG BP block administered as a single-penetration multiple-injection-technique at one of three different levels: (1) SCL (2) LIC (3) AX. Ropivacaine 0.75% (20 mL) will be used for all blocks prior to surgery.

结局指标
主要结局
Blockade performance time (seconds)
时间窗: Time (seconds) from the time the ultrasound transducer is placed on the skin and until the needle is taken out of the body.
次要结局
- Duration of time of block postoperatively (hours)(Patient reported the time off ending sensory and motory block)
- Onset time of blockade (minutes)(Time from block completion to complete sensory and motor block is accomplished.)
- Number of needle passes(Number of times the direction of the needle changes while performing the block)
- Patient reported pain related to needle passes (Scale 0-2)(Pain related to block performance reported by the patient right after block completion)
