Policy Tech: Version 10 Special Notes: To prevent specimen contamination by microorganisms, use sterile supplies and Equipment: venipuncture needle, syringe for specimen, chlorhexidine frepp, tourniquet, gauze, Blood Culture Media always consider patient’s weight when choosing appropriate bottles Collection Procedure: 1. Clean venipuncture site with chlorhexidine frepp using back and forth friction scrub for 30 2. Do not retouch site; if you must repalpate for vein, the area must be recleaned using above 3. When required amount of blood is received, remove needle from skin. 4. Hold pressure to site with gauze and apply adhesive bandage when bleeding stops. 5. Remove venipuncture needle from syringe and attach blunt fill needle and transfer device. 6. Remove tops of blood culture bottles and swab with chlorhexidine. 7. Inject blood specimens into bottles, place specimen into the anaerobic Orange bottle, then 8. Label bottle. Indicate whether line draw or peripheral. Label specimens with at least two patient identifiers, such as name, medical record number, and date of birth 9. Discard needle and syringe into a sharps container 10. Send specimen promptly to CCL. If the specimen is coming from the floors, send the audit References: Bowden, V.R., Smith Greenberg, C.(2008). Pediatric Nursing Procedures, 2nd Ed. Philadelphia: Isenberg, H.D. (2004).

A blood culture is a microbiological culture of a peripheral blood sample. As blood is usually a sterile environment, culturing can show the presence of a systemic infection, such as septicaemia. If the culture is positive, the causative micro-organism can usually be identified, and antibiotic sensitivity testing performed. The process of collecting blood for culture can be divided into four steps; explanation and consent, preparation, procedure and aftercare. We shall now look at these stages in more detail. Explanation and Consent
Check that the patient is happy to go ahead with the procedure. Ask the patient if they would like a chaperone present PreparationWhen in the treatment room, prepare your equipment on an appropriate equipment trolley
Once at the patient’s bedside
Procedure
If you are unsuccessful in obtaining blood, remove needle and restart the whole procedure. Never reinsert the same needle into a patient. It is good practice to have maximum of two attempts before finding a colleague to attempt instead. If the patient is known to be “high risk”, place bottles and request form into a biohazard bag. Both the sample and the form should also be labelled with “Danger of Infection” stickers or hospital equivalent. AftercareInstruct the patient to inform the nursing staff if:
Thank the patient and leave the patient’s bedside
Whenever possible, a peripheral sample is preferred over a sample obtained from a line, unless a line infection is suspected. When drawing multiple blood samples from a line, always draw the blood culture first. Do not discard any blood from the line. Use this initial blood in the line, as this may be the best source if an organism is present. Equipment
*NOTE: Mycobacterial cultures require different containers. Recommended Testing
