What is the recommended method for vascular access in pregnant trauma?

• A. Start one or two IV lines of normal saline
• B. Start arterial line
• C. Start no IV
• D. Administer medications first

Answer: (A)

In trauma, the first priority is to establish rapid, reliable access to support circulation and permit immediate treatment. For a pregnant patient with trauma, maintaining maternal perfusion is crucial for both mother and fetus, so you want prompt IV access to give fluids and medications.

The best approach is to start one or two large-bore IV lines and begin isotonic crystalloid (normal saline). Large-bore lines allow fluids to infuse quickly, which is essential in hemorrhagic shock, and having two lines provides redundancy and enables simultaneous administration of fluids, drugs, or blood products. This method also facilitates continuous monitoring and rapid cross-matching if needed.

An arterial line is valuable for continuous blood pressure monitoring and frequent blood gas sampling, but it’s not the initial method for vascular access in an acute resuscitation scenario because it is more invasive and does not immediately deliver fluids or medications. Not establishing IV access would delay resuscitation, and delaying treatment to place an arterial line isn’t appropriate. If IV access is difficult, other routes like intraosseous access can be used as a backup, but the primary step remains establishing IV lines with isotonic saline.
