Nerve Stimulator Versus Ultrasound-guided Infraclavicular Block

Not Applicable

Completed

• Conditions: Pain

• Registration Number: NCT02344615
• Lead Sponsor: Cheju Halla General Hospital

Brief Summary

The investigators compared the postoperative analgesia of nerve stimulator-guided and ultrasound-guided infraclavicular block for upper extremity surgery.

Detailed Description

Ultrasound (US)-guided peripheral nerve block has increased in popularity. It has many advantages such as improved success rate, faster onset time, fewer needle passes, shorter performance time, and reduced procedural pain and vascular puncture. However, there is no information about postoperative analgesia.

Therefore, the investigators tested whether ultrasound-guided peripheral nerve block enhanced the postoperative analgesia for upper extremity surgery compared with nerve stimulator (NS) guidance.

Primary Outcome Measures

Name	Time	Method
Duration of postoperative analgesia	at 24h after surgery	time from completion of local anesthetic injection until the first request for an analgesic

Secondary Outcome Measures

Name	Time	Method
number of needle redirections	at 30 min after block placement	either forward or backward movement of needle at least 1 cm or more
patient discomfort	at 30 min after block placement	pain score (0-10) during the procedure
paresthesia	at 30 min after block placement	presence of paresthesia during the procedure
postoperative dysesthesia	at 24h after surgery	presence of any paresthesia in the operated extremity
supplemental analgesia	at 24h after surgery	Rescue analgesia with 75 mg of IM diclofenac was available on demand.
Pain score	at 24h after surgery
Patient satisfaction	at 24h after surgery	The acceptance of the anesthetic technique was evaluated using a two-point score: 1, satisfactory (if necessary, I would have the same anesthetic technique); and 2, unsatisfactory (different anesthetic technique).
block performance time	at 30 min after block placement	the time between the block needle insertion and needle withdrawal
onset time	until 30min after completion of local anesthetic	complete block of sensory nerve (radial, ulnar, median, musculocutaneous, and medial antebrachial cutaneous nerve)
motor block of hand	at 24h after surgery	presence of motor block in the operated hand
