Randomized Controlled Trial Clinical Trial[Determination of EC50 of ropivacaine and bupivacaine for postoperative epidural analgesia by up-down sequential allocation].
To determine the median effective concentration (EC50) of ropivacaine and bupivacaine for postoperative epidural analgesia, and compare the efficacy of the 2 analgesics. ⋯ Up-down sequential allocation is a simple, efficient and reliable method for EC50 determination of ropivacaine and bupivacaine, and the former has a lower efficacy during postoperative epidural analgesia.

[Treatment of 48 cases of frozen shoulder with manual therapy under brachial plexus anesthesia through a retained tube].
Manual therapy was adopted for treatment of 48 patients with frozen shoulder, under brachial plexus block through a tube that was not withdrawn until 1 to 2 weeks after the initiation of the treatment course. Satisfactory results were achieved in most of the patients after the treatment, indicating the safety and feasibility of brachial plexus block for pain relief through long-term retention of the tube.
