Abstract:
Maternal positioning, medications, and other modulations to the venous system can affect maternal and fetal well-being. The venous system is a dynamic reservoir for blood volume, in which a virtual point of conversion between unstressed volume (Vu) and stressed volume (Vs) exists. The anatomic and physiologic changes associated with hypotension (e.g. supine and neuraxial technique-induced), hypertension (e.g. preeclampsia), and fluid management (e.g. early recovery after cesarean delivery protocols) are opportunities to consider the important role of the venous system in pregnancy.
