Evaluation Of The Effects Of Changes In Operating Table Position On Perfusion Index And Spinal Anesthesia

The aim of this observational study is to investigate how table position affects the development of block in patients undergoing spinal anesthesia. Perfusion index measurements will be used to answer this question. Patients who will undergo perfusion index measurement during surgery will be included in the study. These patients will be compared with patients whose anesthesiologists chose not to position them on the operating table. The study is planned to continue for approximately 40 days, and the data collected during this period will be used for evaluation.
