Anxiety before surgery may trigger fainting during spinal anesthesia

This study looks at whether patients who are more anxious before surgery are more likely to have a sudden drop in heart rate or blood pressure (vasovagal event) during spinal anesthesia. Researchers will measure anxiety levels in 1,500 adults aged 18-65 and track any such events. The goal is to better understand the link between anxiety and these reactions, not to test a new treatment.
