Aortocaval compression<br />

In the third trimester, a pregnant woman is at risk of aortocaval compression if she lies flat<br />

on her back. In this position, the gravid uterus can compress the vena cava (compromising<br />

venous return) and/or the aorta. <strong>The</strong> result can be maternal hypotension and reduced uterine<br />

perfusion. Aortocaval compression can be prevented by having the parturient remain in<br />

the lateral position, or slightly tilted to the left.<br />
