Brief Summary
The aim of our study is to observe the effect of head-neck position of patients scheduled for thyroidectomy, on carotid artery blood flow, regional cerebral oxygen saturation measured using near-infrared spectroscopy technology, and postoperative cognitive dysfunction.

Interventions
Neck was rotated about 30-45 ° to the opposite side of the image. The common carotid artery and internal jugular vein were viewed transversely on the B Mode USG image. Then, the probe was rotated approximately 90 ° and the carotid artery was visualized in the longitudinal plane. The probe and guide line were adjusted so that the Doppler angle was 60 °. The image was created with the guiding line parallel to the blood flow. After imaging of the carotid artery bifurcation, measurements were made 1 cm distal to this level.
Eligibility Criteria
Patients between the ages of 18-50 who will undergo total thyroidectomy under general anesthesia due to elective thyroid cancer, Hashimoto's thyroiditis or thyrotoxicosis, in the American Society of Anesthesiologists (ASA) I-II risk group, who are euthyroid in the preoperative period
You may qualify if:
- undergo a total thyroidectomy operation
- ASA I-II
- euthyroid patients in the preoperative period
You may not qualify if:
- Hemoglobin\< 8 g / dl
- Hypertension
- Hyperlipidemia
- Pregnancy
- Patients diagnosed with diabetes mellitus
- Cerebrovascular insufficiency
- Known carotid artery lesion
- Metabolic diseases
- Any intracranial pathology present
- Surgeries exceeding 180 minutes
