Abstract

Objective: To investigate the feasibility of a non-stimulation needle with an external indwelling cannula for upper-limb surgery and acute postoperative pain management. Methods: 62 patients undergoing either scheduled or emergency upper-limb surgery received brachial plexus block of modified interscalene or axillary brachial and then postoperative patient-controlled analgesia (PCA) with local analgesics using a specially designed non-stimulation needle with an external indwelling cannula. The outcome measurements included anesthetic effect, acute or chronic complications, postoperative analgesic effect and patient's satisfaction. Results: The success rate of anesthesia was 96.8%. The single attempt placement with the external indwelling cannula was achieved in 85.2% of patients with axillary brachial plexus block and 78.8% with modified interscalene brachial plexus block. The incidence of severe intoxication was 3.7% with axillary brachial plexus block and 3.0% with modified interscalene brachial plexus block. No hematoma at the injection site, Horner's syndrome, hoarseness or dyspnea was observed. Postoperative analgesic effect was achieved in 100% and activities were slightly lowered in 91.7%. The incidence of nausea and vomit was 8.3%; patient's satisfaction was 9.1 on a 10-point scale system. Infection, nerve injury and respiratory depression were absent during the catheter indwelling. The indwelling time of external indwelling cannula was 30.5 h on average. There was no nerve injury related complication after withdrawing the external indwelling catheter. Conclusions: Brachial plexus block using a non-stimulation needle with an external indwelling cannula has favorable intra-operative anesthetic benefit and provides an excellent postoperative analgesic outcome. The low incidence of complications and favorable patient's satisfaction suggest that non-stimulation needle with an external indwelling cannula is a useful and safe anesthetic tool in brachial nerve block and acute postoperative pain management.
