Official title
Evaluation Of The Effects Of Changes In Operating Table Position On Perfusion Index And Spinal Anesthesia: An Observational Study
Overview
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.
Detailed description
Patients aged 18-65 years in ASA1-3 risk group who will undergo lower extremity surgery with spinal anesthesia are planned to be included in the study.
Primary outcome measures
- perfusion index [Time frame: 5 min]
Eligibility criteria
Inclusion criteria
- Patients who will undergo lower extremity surgery within the specified time frame, are in ASA 1-3 risk group, have no additional medical conditions, and will receive spinal anesthesia.
Exclusion criteria
- Patients under 18 and over 65 years of age Patients who have received anesthesia other than spinal anesthesia Patients with peripheral artery disease Patients with nail polish, etc. on their nails
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
