Comparing two ways to monitor blood pressure in surgical patients

This study compares two methods of measuring blood pressure during the start of anesthesia: one using a small tube in an artery (invasive) and one using a standard arm cuff (non-invasive). It aims to see how well they agree in high-risk patients, which may help doctors monitor blood pressure more accurately and safely.

This study checks how well a simple arm cuff (non-invasive blood pressure monitoring) works compared to a more direct method using a small tube in an artery during laparoscopic surgery in a head-down position. The findings could help make blood pressure monitoring more accurate and comfortable for future patients.

This study tests a new device that measures blood pressure continuously without needing a needle in your artery. If you are having surgery and already need an arterial line, this device might offer a less invasive way to track your blood pressure during the procedure.

This study compares different places to put an arterial line during major abdominal surgery to see how they affect blood pressure monitoring and treatment. Having an arterial line helps the doctor watch your blood pressure closely during the operation, which may improve your care.

This trial checks whether blood pressure readings from a standard arm cuff are as accurate as readings from an arterial line (a small tube in an artery) during lung surgery with one lung collapsed. If the cuff is reliable, patients may need fewer invasive monitoring methods in the future.

This study compares two methods of placing a small tube (arterial line) in your wrist or arm to monitor blood pressure during heart surgery. Both methods use ultrasound to guide the tube, and the study aims to see which technique works better when the artery is hard to access.
