 Description
 Indications
  • Patients to be transported to an Emergency Department with successful Peripheral IV Access or External Jugular Access whose clinical presentation warrants pre-hospital blood sample collection.
  • Patients 16 years and older
 Contraindications
  • Any patient whose clinical condition does not warrant IV cannulation.
  • Where prehospital blood collection will delay life saving treatment
  • Patients <16 years old.

Key Aseptic Terms for Prehospital Blood Sampling

  • Key Sites:
    • Bung
  • Key Parts:
    • Multi-sample Adapter
 Patient Factors & Considerations
  • The acquisition of pre-hospital phlebotomy has proven to result in shorter ED times by having the bloods sent to the lab earlier.
  • Failure to draw blood does not necessarily indicate failed cannulation. Consider troubleshooting by either manipulating patient limb or using gentle movement of cannula to attempt to induce flow.
  • If blood flow appears slow or restricted, loosen tourniquet gradually to increase flow.
  • Complete the following fields on the pathology request form: ‘clinical notes’ – case number and chief complaint i.e. chest pain, receiving ED and endorse with signature and AP number in ‘collection details’ field. Ensure the Unit No. is left blank and the patient details have been entered correctly.
Critical Care Paramedic only
  • The only tube available on the Rescue Helicopter will be the 6 ml Pink top EDTA for whole blood haematology determinations and blood donor screening.
  • Tube inversions ensure mixing of anticoagulant (EDTA) with blood to prevent clotting.
    • To avoid mismatching, always use prior to administering any blood products.
    • Ensure the sample is labelled accurately prior to arrival at the ED to limit potential misidentification.

    • Insert and fill vacutainer tubes in the following order (tubes marked as bold are standard across all ambulances):
    Light Blue Sodium Citrate; for patients on anticoagulation medications, such as warfarin. Fill the tube to the line
    Green Lithium Heparin
    Gold* Serum Separation Tube, for biochemistry.
    Draw x2 for chest pain
    Orange* Rapid serum tube for troponins in regional labs
    Light green* Lithium Heparin Plasma with gel.
    Purple EDTA

    *May or may not be present, depending on your location.

    Additional Information
    • The multi-sample adaptor is classed as a sharp.

    • DO NOT place your finger into the chamber of the adaptor at any time.
