Prep for blood alcohol levels

To clean the site before drawing for a blood alcohol, use hydrogen peroxide not alcohol

2

Prep for blood cultures

Site must be cleaned with 70%-90% alcohol and then 2% iodine.

3

What is the most important step in vein puncture?

Identifying the patient.
Blood drawn on the wrong pt would be negligence.
Drawing on a pt who is refusing is considered battery

4

Tourniquet what do u do with it

Do not keep it in place more 2 minutes

Place 3-4 inches above puncture site

5

Young Little Boys Really Get Girls Labias Going

1. Yellow.
2. Light Blue
3. Red.
4. Gold, red/gray
5. Green
6. Lavender
7. Gray

6

Yellow Top Tube

Sterile
Sodium chloride
For body fluids and blood cultures

7

Light Blue Tube

Sodium Citrate
Coagulation test
PT, PTT, INR

8

Red

No additives

For chemistries, serology (serum), HIV, ABO

Centrifuge- stand 30 minutes tests on serum (liquid part of blood)

10

Gold or red/gray

Has serum separator silicon gel (clot activator) SST
Stand 40 minutes before centrifuge

For RBC, plasma, Buffy coat

Whole blood left at room temp will clot in approx 20 minutes

11

Green

Sodium heparin or lithium heparin (anticoagulant)

For medication levels

12

Lavender

EDTA

For whole blood, Hg, Hct, CBC, ESR, and HbA1C

13

Gray

Potassium oxalate or Sodium fluoride ( anticoagulant)

Just glucose, drug screening, and alcohol screening

14

Royal Blue

Varies by manufactures

Lead, iron levels

15

Other tube info

Tube sizes vary, fill completely to insure proper proportion of additive to blood

Coagulation studies discard first drawn sample

16

Evacuation Tube Method

Medium to large veins

Vacuumed tubes, as blood is drawn into the tube by the force of the negative pressure, the pressure equalizes & blood stops

17

Syringe method

For small delicate veins

Can only obtain 10 ml blood

Transfer to tubes immediately

18

To make draws easier, what can you do?

Have Pt make a fist

Apply a warm soak

19

Butterfly (winged infusion set) method

Back of hand or smaller delicate veins

Drawing on a child
Can be into a syringe or evacuation tubes
21g - 25g 3/4 inch

21

What if a hematoma forms

If bleeding continues....

History of collapsed veins

Apply firm pressure for 3 minutes, apply ice, notify supervisor.

Bleeding con'ts after blood draw complete - apply pressure, elevate above head & use ice

Hx of collapsed veins (top & bottom of vein touch stopping blood) - do not use evacuated tube method, small vein protocol

22

Errors in blood draw that cause hemolysis

4

-Syringe to quickly
-tourniquet not loosened during draw
-removing needle before tube
-needle gauge too small (18 gauge needed for cmc)

23

Error causing hematoma


Hematoma. Large bruised area caused by blood leaking into surrounding tissues

1. Needle goes through vein
2. Remove needle with tourniquet on
3. Not enough pressure applied after needle has been removed
