ClinConnect Summary
This clinical trial is studying two different methods of monitoring blood pressure in patients undergoing non-cardiac surgery with general anesthesia. The goal is to see which method is better at preventing low blood pressure, known as hypotension, during the critical time right after anesthesia is given and before the surgery begins. One method uses a continuous monitoring technique through a small catheter placed in the artery, while the other uses a less invasive method that checks blood pressure every minute. Researchers want to find out if checking blood pressure every minute is just as effective as continuous monitoring.
To participate in this study, you need to be an adult aged 19 or older who is scheduled for non-cardiac surgery and will receive general anesthesia. However, if you have certain health conditions that require immediate arterial access or are undergoing emergency surgery, you may not be eligible. If you join the study, you will be monitored closely for low blood pressure during the anesthesia induction phase, and your experience will help doctors understand how to better manage blood pressure in surgical patients.

Eligibility criteria
- Inclusion Criteria:
- • Adult patients aged 19 or older undergoing scheduled non-cardiac surgery with general anesthesia and continuous invasive arterial blood pressure monitoring via the radial artery
- Exclusion Criteria:
- • Arterial access is clinically necessary before induction of anesthesia (e.g., moderate or higher degree of aortic stenosis, moderate or higher degree of heart failure, coronary artery disease requiring revascularization, intracranial aneurysm with a significant risk of rupture, etc.)
- • Emergency surgery
- • American Society of Anesthesiologists (ASA) physical status 5 or 6
- • Arterial access is required in a different artery other than the radial artery (e.g., the femoral artery)
- • Electrocardiogram other than sinus rhythm
- • Refusal to participate in the study
