Comparison of Catheters Orifice Configuration For Continuous Infraclavicular Analgesia

The linear probe will be placed parasagittally at the junction between the clavicle and the choroidal process. After medial to lateral scanning, the branches of the brachial plexus will be seen as posterior, lateral and medial truncus around the axillary artery. Contiplex® FX Non-Stimulating Tuohy Set, 17Ga. x 3½ inches. the Non-Stimulating Needle and the closed-tip multiport catheter will be delivered through the needle and placed at the 6 o'clock position relative to the axillary artery and then secured by forming a tunnel under the skin. After negative aspiration, the location of the catheter will be confirmed by injecting 1-2 ml of local anesthetic under ultrasonic guidance.

Contiplex® Non-Stimulating Tuohy Set, 17Ga. x 3½ inches. hhe Non-Stimulating Needle and the Non-Stimulating open-ended catheter will be delivered through the needle and placed at the 6 o'clock position relative to the axillary artery and then secured by forming a tunnel under the skin. After negative aspiration, the location of the catheter will be confirmed by injecting 1-2 ml of local anesthetic under ultrasonic guidance.

A patient-controlled analgesic device will be attached to the catheter for postoperative analgesia. continuous peripheral nerve patient-controlled analgesia is as follows: 0.125% bupivacaine; hourly infusion: 4 ml / hour, pca dose (bolus): 5 ml / hour, lock-up time: 30 min, 4-hours limit: 30 ml.
