Comparing two ways to measure blood pressure during anesthesia
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled for surgery under general anesthesia.
- Your doctor has decided that you need an arterial line (a small tube in your wrist or arm) to monitor your blood pressure during anesthesia.
- Your blood pressure readings are similar on both arms (less than 5 mmHg difference).
- You can lie flat on your back during the start of anesthesia.
- You have at least one of these conditions: peripheral artery disease, carotid artery disease, severe coronary artery disease, or high blood pressure requiring three or more medications.
- You are not pregnant and have not participated in this study before.

This trial compares two ways to measure blood pressure during robot-assisted prostate surgery: a cuff on the arm (oscillometric) vs. a tiny tube in an artery (intraarterial). It aims to see if the cuff method is just as reliable, which could make monitoring simpler and less invasive.
This study compares two methods to measure blood pressure (PPV and PVI) when you are lying on your back or on your stomach during surgery under general anesthesia. The goal is to see which method works better in each position.
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 compares measuring blood pressure through an arm artery (radial) versus a leg artery (femoral) during heart surgery that uses a heart-lung machine. The goal is to see which method works better and is safer for patients.
This trial tests a device that monitors blood pressure continuously during surgery using a finger cuff, instead of the standard arm cuff that gives readings every few minutes. You may be able to join if you are having surgery and are at higher risk of complications during anesthesia.
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.
