Prior to the closure of an arteriotomy, which of the following solutions should the surgical technologist have ready for irrigation of the operative site?

In the context of closing an arteriotomy, having heparinized saline ready for irrigation is essential. Heparinized saline serves multiple purposes: it helps to keep the surgical site well-lubricated, prevents the formation of blood clots in the area being operated on, and maintains vascular patency by providing some degree of anticoagulation. This is particularly important in the context of arteriotomies, where blood vessels are involved, and there is an increased risk of thrombosis.

Lactated Ringer’s solution is typically used for fluid resuscitation and electrolyte replacement, not specifically for irrigation during vascular procedures. Protamine sulfate is an antidote to heparin, and its role comes after administering heparin rather than during the procedure. Sterile water can potentially damage tissues and should not be used for irrigation in this context, as it lacks the necessary electrolytes and does not perform the anticoagulation function required post-operatively.

Therefore, heparinized saline is the most appropriate choice prior to the closure of an arteriotomy, as it aligns with the need to manage vascular integrity and ensure optimal surgical outcomes.
