Study Details

Study Description

Brief Summary

The ultrasound-guided selective blockade of the saphenous nerve in the adductor canal provides effective analgesia and reduces postoperative pain in patients undergoing arthroscopic medial meniscectomy. Selective blockade of the saphenous nerve in the adductor canal provides effective analgesia without quadriceps muscle weakness. It has been shown that the adductor canal block (ACB) block increases the spread of local anesthetics in a distal and proximal way. Therefore, the proximal spread of local anesthetics may cause possible quadriceps weakness. The distal spread of local anesthetics may increase analgesic effect via sciatic nerve. The different volumes for ACB is a topic of discussion. The aim of this study is to compare the different volumes of US-guided ACB performing for postoperative analgesia management after total knee arthroplasty surgery.

Detailed Description

Knee arthroplasty is one of the most common orthopedic procedures. Patients may complain severe pain due to the surgical trauma and the prosthesis. Opioid agents are commonly used for analgesia management. However, opioids have adverse effects such as nausea, vomiting, sedation and respiratory depression. Peripheral nerve blocks such as femoral block, adductor canal block (ACB) may be performed to reduce opioid consumption and opioid-related side effects.

Selective blockade of the saphenous nerve in the adductor canal for knee surgery provides effective analgesia without quadriceps muscle weakness. This is an important advantage of ACB since it there is no motor blockade in the postoperative period. Blocking of the motor branches leads to delaying of the mobilization and it increases the patient's falling risk. ACB, targets the saphenous nerve and the vastus medialis branch which are the two largest sensorial nerves of the femoral nerve that innervates the knee. ACB blocks the articular branches of the obturator nerve at the same time. Since the ACB is performed at the distal site of thigh it does not target majority of the efferent branches of the quadriceps muscle, therefore the strength of this muscle may not be affected. ACB is usually performed with a volume of 10-30 ml and studies may be needed including different volumes to understand its effectiveness.

The aim of this study is to compare the different volumes (20 ml, 30 ml, and 40 ml) of US-guided ACB for postoperative analgesia management after total knee arthroplasty. The primary aim is to compare postoperative opioid consumption and the secondary aim is to evaluate postoperative pain scores (VAS), motor blockage, the first mobilization time, and adverse effects related with opioids (allergic reaction, nausea, vomiting).

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: 20 ml volume adductor canal block

ACB will be performed at the end of the surgery. Patients will be administered tenoxicam (Tilcotil 20 mg flakon) 20 mg IV every 12 hours in the postoperative period. A patient controlled device prepared with 5 mg/ ml tramadol (100 mg-Contramal ® ampul) will be attached to all patients with a protocol included 10 mg bolus without infusion dose, 20 min lockout time and 4 hour limit. If the VAS score will be ≥ 4, 0,5 mg/kg-1 meperidine (Aldolan ampul 100 mg/2 ml) IV will be administered.

Drug: 20 ml volume adductor canal block
ACB will be performed at the end of the surgery. After identifying the adductor canal, by using the in-plane technique, the probe will be placed at the mid-thigh, half the distance between the inguinal crease and the patella, for block location. The superficial femoral artery will be visualized dorsal to the sartorius muscle. Then, the probe will be removed to distally. At this level, the hyperechoic view of the saphenous nerve will be visualized lateral and anterior to the artery in the subsartorial region. 5 mL of saline will be injected to confirm the proper injection site, and then a dose of 0.25% bupivacaine (Buvasin %5 flakon) 20ml will be injected here.

    The primary aim is to compare perioperative and postoperative opioid consumption. Opioid consumption will be recorded at the first 48 hours period postoperatively. (postoperative 0-8, 8-16, 16-24, 24-48 hours)

Secondary Outcome Measures
