The Efficacy of Continuous Femoral Nerve Catheter Orifice Configuration for Postoperative Analgesia in Knee Arthroplasty

Summary

Femoral nerve catheter for postoperative analgesia will be included in the adult patients undergoing total knee arthroplasty 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 patients , the number of pushing the button the amount of bolus dose given, and 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.

Conditions

• Anesthesia
• Catheter Blockage
• Knee Arthropathy
• Pain, Postoperative

Interventions

PROCEDURE

CEMP (closed-ended multiport catheter) group

After sterile preparation and large inguinal crease draping, with the US probe in a sterile sleeve or cover , we will proceed to hydrolocalization with 5-10 mL 5% dextrose in order to open the space between the femoral nerve and the superior part of the ilio-psoas muscle. The Contiplex® FX Non-Stimulating Tuohy Set, 17Ga. x 3½ inches. the Non-Stimulating Needle and the closed-tip multiport catheter will be then inserted under control and its position assessed between the femoral nerve and the superior aspect of the ilio-psoas muscle. Some aliquots of 5% dextrose will inject to confirm correct dispersal of the solution along the femoral nerve. The catheter will be tunnelled subcutaneously.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.
