Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Spinal anesthesia is a regional anesthesia method used for surgical procedures generally involving the lower abdominal area, perineum, and lower extremities. Various tests are performed to evaluate the block level after spinal anesthesia, incluyding pinprick test, cold application, and motor examination. These tests are performed to check whether the pain, sympathetic and motor nerve fibers are affected, respectively, after the block; and good communication with the patient is important here. However, it is extremely difficult to evaluate these tests in pediatric, geriatric, mentally retarded or uncooperative patients.

Sympathectomy can be used as a criterion to evaluate the success of the block that occurs after the spinal anesthesia procedure. Sympathetic nerve fibers are the first to be affected by the block, and the success of the block can be evaluated with the revealed sympathectomy. Sympathectomy in the lower extremities after spinal block increases arterial blood flow. This increase in blood flow can be detected by the Pulsed Wave Doppler feature of USG.

Pulsed Wave Doppler USG examination

Pulsed Wave Doppler USG examination of the posterior tibial artery on the left or right lower extremity will be performed before spinal anesthesia, at the 5th and 10th minutes after the spinal anesthesia. Blood flow velocities and vessel diameters will be measured.
