Measure Description
Time Frame
the affection of nerve block
Time Frame: 30 minutes
The anesthetic efficacy of five nerves, respectively named lateral antebrachial cutaneous nerve, medial cutaneous nerve of the forearm, radial nerve, median nerve, and ulnar nerve was assessed within 30 min after anesthesia. The next concentration of ropivacaine was adjusted according to the response of the previous patient using up-down sequential allocation.
