Summary

The goal of this observational study is to determine the effect of adding adductor canal block to popliteal sciatic nerve block on patient-surgeon satisfaction, intraoperative sedation need, tourniquet pain, return time of motor block, and postoperative pain in patients undergoing hallux valgus correction surgery. The main question it aims to answer are:

* Does peroperative pain decrease?
* Do patient-surgeon satisfaction increase? The patients were divided into two groups, the Popliteal Sciatic Block (PSB) group, and the Popliteal Sciatic Block + Adductor Canal Block (PSB + ACB) group.

Conditions

  • Popliteal Sciatic Nerve Block
  • Adductor Canal Block

Interventions

PROCEDURE

Popliteal Sciatic Nerve Block

Patients undergoing popliteal sciatic block, the side where the procedure would be performed in the prone position was sterilized after appropriate antisepsis. After visualizing the popliteal artery in the popliteal fossa with the probe it was advanced proximally in a horizontal and minimally lateral position to determine the point of separation of the tibial and peroneal nerves from the sciatic nerve. Subcutaneous local anesthesia was applied at this point after the skin, and the stimulator needle was advanced towards the sciatic nerve in an in-plane approach, passing through the skin and subcutaneous tissue, and then the nerve stimulator was opened up to 1 mA. After observing motor movement in the foot, the stimulator was reduced to 0.3-0.5 mA, and after observing motor movements for duration of 0.1 ms, 10 ml of 0.5% bupivacaine + 10 ml of 2% prilocaine were administered to the target tissue

PROCEDURE

Adductor canal block

Patients in the group undergoing popliteal sciatic block + adductor canal block, with the extremity to be blocked slightly externally rotated, the anterior part of the thigh was prepared with the necessary antiseptic procedures while the patient was in the supine position. Using an ultrasound probe, the femoral artery was visualized by advancing the ultrasound probe distally, and the saphenous nerve was identified just lateral to the femoral artery, beneath the sartorius muscle. At the junction of the sartorius muscle and vastus medialis, 10 ml of 0.5% bupivacaine + 10 ml of 2% prilocaine were applied to the periphery of the saphenous nerve. Subsequently, the patient was turned prone, and a popliteal sciatic block was performed.
