What is the correct position for a third-trimester patient who is bleeding?

The left lateral recumbent position is the recommended position for a third-trimester patient who is bleeding. This position helps prevent compression of the inferior vena cava, a major vein that returns blood to the heart. During the later stages of pregnancy, especially in the third trimester, the weight of the uterus can compress this vein when the patient is in a supine position. Such compression can lead to reduced venous return, decreased cardiac output, and hypotension, which could further compromise the mother's and the fetus's well-being.

Positioning a pregnant patient in the left lateral recumbent position enhances blood flow to the heart and optimizes blood circulation to the fetus. This position is often the safest and most effective for managing bleeding in this demographic, ensuring both maternal and fetal stability while reducing the risk of complications from the positioning itself.

Other positions like sitting upright may not provide the stability needed for maternal circulation, and being in the supine position can cause significant cardiovascular changes due to vena cava compression. Right lateral recumbent is less favored than the left due to potential similar compression issues but may still be considered if necessary. However, the left lateral recumbent remains the best practice for handling third-trimester bleeding scenarios.
