Abstract :Objectives: To assess spinal and cerebral oxygenation with near-infrared spectroscopy method during spinal surgery in prone position. Methods: This prospective study included 64 patients, who were prepared for posterior spinal instrumentation and laminectomy surgeries. Group 1: 31 patients who had posterior spinal instrumentation; Group 2: 33 patients who had at least two levels of disk operation insert ignore into journalissuearticles values(Laminectomy);. The following were recorded for all patients before and after anesthesia induction in supine position, after induction in prone position, during operation insert ignore into journalissuearticles values(beginning, middle and end of surgery); in prone position and before waking up in supine position: cerebral oxygen saturation insert ignore into journalissuearticles values(NIRSs); measurements, spinal oxygen saturation insert ignore into journalissuearticles values(NIRSp); measurements, peripheral oxygen saturation insert ignore into journalissuearticles values(SpO 2 );, heart rate insert ignore into journalissuearticles values(HR);, invasively monitored systolic arterial pressure insert ignore into journalissuearticles values(SAP);, diastolic arterial pressure insert ignore into journalissuearticles values(DAP);, mean arterial pressure insert ignore into journalissuearticles values(MAP); values. Results: There was no significant difference between two groups in terms of the variables of age, weight, anesthesia and surgery duration insert ignore into journalissuearticles values( p > 0.05);. MAP values were significantly different in both groups before induction, during operation and postoperative periods insert ignore into journalissuearticles values( p < 0.05);. NIRSs were significantly lower at mid-operation and at the end of operation insert ignore into journalissuearticles values( p < 0.05);. NIRSp values had no significant difference in any period insert ignore into journalissuearticles values( p > 0.05);. We found no significant difference between groups in HR, SAP, DAP, MAP, NIRSs and NIRSp parameters insert ignore into journalissuearticles values( p > 0.05); compared at different times. Conclusions: MAP dropped depending on induction and prone position. Cerebral oxygenation significantly decreased at the time of mid-operation and at the end of operation but spinal oxygenation had no significant decresase. Compared to laminectomy, posterior stabilization surgery did not pose an additional risk to the patients in terms of spinal and oxygen saturation.
