In this episode, I explore the latest evidence on the use of saline locks!
A saline lock – sometimes called a “hep-lock” in reference to how it used to be used – is an intravenous (IV) catheter that is threaded into a peripheral vein, flushed with saline, and then capped off for later use. Nurses use saline locks to have easy access to the vein for potential injections. They can be useful in administering drugs as needed, and in the event of emergency surgery.
What is the latest research on the use of saline locks in labor and delivery? What is the evidence for the saline lock in someone who wants an un-medicated birth or wants to avoid medical interventions as much as possible? Should a saline lock be in place “just in case” it may be needed? I’ll cover the evidence on this topic, along with the risks and benefits.
