Summary

Co-administration of the sciatic nerve block and femoral nerve block may provide anesthesia and analgesia in patients undergoing lower extremity surgery. Several approaches to sciatic nerve block have been described. The anterior and posterior approaches are two of the approaches used to make the sciatic nerve block. In our study, n = 20 patients for Group A and n = 25 patients for Group P were included. Then, sciatic nerve block and femoral nerve block were performed to each patient by using anterior or posterior approach randomly. After the block is performed, the sensory and motor block start and end times, the first intraoperative fentanyl requirement time and total amount of fentanyl required, the first Diclofenac sodium requirement time, and the total amount of diclofenac sodium that patients required were determined. As the groups were compared to each other; the time to start sensory block was statistically significantly lower, the first fentanyl requirement time was statistically significantly earlier and the total amount of fentanyl required was statistically significantly lower in Group P. Patient satisfaction, anesthesia quality and surgical quality were statistically significantly higher in Group P. In this study, the investigators concluded that if a patient does not have pain secondary to fracture, posterior approach to sciatic nerve block can be performed, whereas, if a patient has pain secondary to fracture, anterior approach to sciatic nerve block can be performed in order to avoid repositioning.

Conditions

  • Ankle Fractures

Interventions

PROCEDURE

Anterior sciatic nerve block

A straight line along the femoral catheter was drawn between the anterior superior iliac spine and the finger palpating the pubic bone, the index finger was placed over the femoral artery pulse, a line was drawn perpendicular to the femoral fold. Over the pulse of the femoral artery, a point 4-5 cm lateral. The sciatic nerve was imaged by USG along the needle route and the needle was advanced to the nerve.

PROCEDURE

Posterior sciatic nerve block

Patient was positioned laterally, with the limb to be blocked uppermost. The lower leg was straight extended and the upper extremity was bent 90° from the knee and was directed forward on the lower straight extended extremity. The patient's greater trochanter and posterior superior iliac spine were palpated and joined with a line, and a line was drawn 4 cm above the first line perpendicular to the caudal line. The USG probe was placed between the greater trochanter and the coccyx at the entry point of the needle and the needle was advanced by imaging the nerve.
