Placement of catheters in the abdominal aorta produces an obstruction which is manifested by decreased extremity blood flow, muscle oxygen availability, and temperature, and which is greater with 5.0F catheters and more pronounced in animals weighing less than 1.6 kg. Placement of the catheter below the aortic bifurcation did not produce any change in blood flow and oxygenation of the contralateral extremity, suggesting that this is a preferred site. These and other complications could be detected by differential monitoring of extremity and core temperature or extremity tissue oxygen availability.
