Details and patient eligibility

About

The investigators aimed to determine intracranial pressure changes during spinal and general anesthesia by using optic nerve sheath diameter and near infrared spectrometer in urologic surgery patients in lithotomy position. Also the investigators plan to evaluate to measure intrathoracic pressure effects to intracranial pressure.

Full description

The patients will be divided into 2 groups as those who underwent general anesthesia and spinal anesthesia.Both groups at the specified times.

(The patient is supine for both groups before the start of the anesthesia procedure.) position T0, for group G, T1G 2 minutes after intubation, T1S 2 minutes after spinal anesthesia for group S, two T2, lithotomy 5 minutes after the lithotomy position for the group lithotomy to T3 30 minutes after the T4, T5 in PACU ) 60 minutes after optic nerve sheath diameter (OSC) values and lung assessment (LUS), cerebral cerebral palsy with Near-infrared spectroscopy (NIRS) oxygenation, mean arterial pressure, peripheral oxygen saturation, serum sodium, arterial carbon dioxide values and heart rate values will be recorded and significant statistical differences will be evaluated.
