What does the term 'Double dart' refer to in refractory shock management?

• A. Two needles placed simultaneously for vascular access
• B. Two darts used for hemostasis
• C. Two IV lines inserted sequentially
• D. Double dose TXA administration

Answer: (A)

The key idea here is speed and reliability of venous access in a patient in refractory shock. The term “double dart” refers to placing two IV needles/catheters at the same time to establish dual venous access quickly. Having two simultaneous access points lets you start two infusions immediately, provides redundancy if one line is difficult or fails, and speeds up delivering fluids, blood products, or medications when every moment counts.

This approach is focused on rapid resuscitation through vascular access rather than on hemostasis tools, sequential line attempts, or pharmacologic dosing strategies like TXA. In practice, securing two ready-to-use IV routes minimizes delays in critical resuscitation and helps achieve the needed volume and medication delivery more efficiently in the field.
