Infraclavicular nerve catheter for postoperative analgesia will be included in the 70 adult patients undergoing upper extremity surgery included in the study. These patients will be randomized to the catheter tip configuration as CEMP (closed-ended multiport catheter) group and OESP (open-ended single port catheter) group. Patient controlled analgesia device will be attached to the peripheral nerve catheter of these patients. Demographic data of the number of pushing the button, the amount of bolus dose given, the total dose given in the patient controlled anesthesia device, the need for additional analgesia and the amount, pain scores, complications will be recorded for three days postoperatively. Records will be compared statistically.
