This randomized controlled trial will compare arterial pressure measurements obtained from radial artery catheterization (the current standard method of monitoring) with those obtained from brachial artery catheterization (a more accurate reflection of central arterial pressure). At the end of the study, we are looking to answer the following questions:\n\n1. Does arterial pressure measurement sites influence the amount of vasopressors that is administered during major abdominal surgeries?\n2. What are the instances where there is a difference between peripheral (radial catheter) and central (brachial catheter) monitoring and what are the risk factors leading to the appearance of this radial-brachial pressure gradient?\n3. With the data collected, can artificial intelligence based analysis help predict the reliability of a radial monitoring and help guide clinicians on choosing a peripheral versus central arterial pressure monitoring site? All adult participants who are scheduled for elective major abdominal surgeries and meeting our inclusion criteria will be approached and included if they consent. Participants will be randomized 1:1 in the intervention group and the standard of care group. In the intervention group, the brachial arterial line will be used intraoperatively to guide vasopressor and fluid administration. A radial line will also be installed to measure the radial arterial pressure simultaneously, but will not be used to guide hemodynamic management. In the standard of care group, both lines will be installed just like in the intervention group, however, it is the radial arterial line that will guide fluid and vasopressor administration. In both groups, the anesthesia protocol will be standardized and the anesthesiologist will be blinded to the arterial pressure measurement site.",[99,100,101,102,103,104,105,106,107],"Perioperative Care","Hemodynamics","Monitoring Blood Pressure","Arterial Lines","Anesthesia","Vasopressor","Fluid Management","Artificial Intelligence in Operating Room","Artificial Intelligence (AI)",[109,110,111,112,113],"Comparison of arterial catheterization sites on hemodynamic monitoring","Incidence of radial-brachial pressure gradient","Risk factors of radial-brachial pressure gradient","Effect of arterial catheterization sites on hemodynamic management","Effect of peripheral vs central arterial pressure measurements in intraoperative hemodynamic management","NOT_YET_RECRUITING","2025-05-13",{"date":117,"type":118},"2025-05-21","ACTUAL",{"date":120,"type":93},"2025-09",{"date":122,"type":93},"2028-12",{"name":5,"class":6},1]
