What is steady state in phlebotomy?

One way to ensure the results are accurate and consistent is to draw blood from patients when their body is at a homeostasis state.

Then, what does phlebotomy mean in medical terms?

Phlebotomy: Obtaining blood from a vein. Today phlebotomy is done more neatly by puncturing a vein with a needle. Phlebotomy may be done in order to obtain blood for diagnostic tests or to remove blood for treatment purposes (eg, to relieve the iron overload in hemochromatosis).

Why is blind probing not recommended as a phlebotomy technique?

The basilic vein is a perfectly acceptable vein to puncture and in many cases is the prominent vein in the antecubital area. However, blind probing for this vein puts the patient at risk. If the patient experiences a shooting pain sensation, do not attempt to salvage the venipuncture.

What affects basal state?

Basal state factors: Age, altitude, dehydration, diet, lipemia or lipemic, diurnal variation's, drugs, exercise, fever, gender, jaundice, position, pregnancy, smoking, stress, temperature and humidity, environment. Many drugs can alter physiologic functions and may have side effects.

What are different methods for collection of blood sample?

Three popular methods of blood collection are:
  • Arterial sampling.
  • Venipuncture sampling.
  • Fingerstick sampling.

Why is accession important to the phlebotomist?

Sample accession solves the problem of identifying different samples by sample types by showing a list to the phlebotomist, listing exactly which samples are in queue of which patient. Once collected the phlebotomist can acknowledge the collection of sample by clicking Receive and it moves on for processing.

What are the side effects of a phlebotomy?

Hematoma, allergy, hyperventilation, air embolism, anemia and thrombosis are other side effects occasionally caused by phlebotomy.

In the era of lyophilized anticoagulants, order of draw is no longer important. Contamination of serum samples with K EDTA will occur routinely if order of draw is not followed. Modern lab equipment can tell the difference between K from the EDTA tube and K from the patient, so order of draw is not important.

How often do nerves get damaged when doing phlebotomy?

Anecdotal reports of difficult access requiring multiple attempts often precede the nerve injury. When reviewing the blood donation population specifically, the incidence of nerve injury was found to be between 1 in 21,000 and 1 in 26,000 venipunctures.

Can you get nerve damage from drawing blood?

Cadaveric studies have demonstrated a great deal of variability in the nerves of the antecubital fossa in relationship to veins, suggesting that even a nontraumatic, straightforward venipuncture can directly damage a cutaneous nerve.
