What is the safest position for treating a pregnant patient in their third trimester with swollen feet and ankles?

The safest position for treating a pregnant patient in their third trimester with swollen feet and ankles is side-lying with legs level with the heart. This position helps alleviate pressure on the inferior vena cava, which can become compressed when the patient lies supine. Compression of this major vein can impede blood flow back to the heart, potentially leading to reduced circulation and increased swelling in the lower extremities.

Being in a side-lying position allows for better venous return and can help alleviate some of the swelling that occurs due to increased fluid retention in pregnancy. Keeping the legs level with the heart ensures that there is no additional strain from elevation, which might not be as comfortable or effective depending on the individual patient’s condition.

Additionally, this position allows for enhanced comfort during treatment, as it helps support the weight of the abdomen and reduces the risk of positional discomfort or squeeze from the weight of the baby pressing on internal structures. This makes side-lying with legs level with the heart a beneficial and safe option for both the mother and the practitioner conducting the treatment.
