IV Access & Infection Prevention in the Field

Why IV access matters at AEMT level

Intravenous access enables fluid resuscitation and medication delivery beyond EMT-Basic scope. MedlinePlus notes that IV fluids can replace volume lost from bleeding, vomiting, or dehydration—when clinical judgment supports their use.²

IV therapy is not automatic for every patient. Weigh benefits against on-scene time, patient stability, and transport distance.

Aseptic technique

The CDC promotes safe injection practices: use single-dose vials appropriately, never reuse needles or syringes, and maintain sterile technique during catheter insertion.¹ Field conditions challenge sterility—minimize contamination by preparing supplies before skin prep and avoiding open packaging in wind or dirt.

Document site, catheter gauge, attempts, and complications. Local infection or infiltration requires removal and reassessment of alternate sites.

Fluids and monitoring

Isotonic crystalloids are common first-line volume expanders for hemorrhagic and distributive shock within protocol. Monitor for fluid overload signs—crackles, increasing work of breathing, and hypertension—in susceptible patients.

Pair fluid therapy with hemorrhage control; IV fluids do not replace definitive surgical care for internal bleeding.
