A. Blood samples should NOT be drawn during IV starts or from established IV catheters except for patients on thrombolytics (to reduce number of sticks), or in an emergency. B. Peripheral lab samples should be obtained using a straight needle and either the Vacutainer or syringe method.
Is it good practice to draw blood samples from a peripheral IV?
Conclusions. Blood sampling from used peripheral intravenous cannulae is a reasonable clinical practice for haematology and biochemistry samples. Potassium samples from used peripheral intravenous cannulae can be used in situations where error up to ±0.47 mmol/L is acceptable.
Can you draw blood from a line?
Blood drawing from indwelling arterial or central venous lines is done through a stopcock with a needleless access device on the sampling port.
Can you draw blood from an arm with an IV?
Therefore, an arm containing an IV should not be used to draw blood specimens if it can be avoided. However, if there is no alternative and an arm with an IV line in place must be used for venipuncture, try to choose a site away from and below the location of the IV.
Can you draw blood from a PICC line?
1. Blood draws via a central line catheter (PICC, subclavian, tunneled) require a written physician’s order. 2. Peripheral-midline catheters should not be used for routine blood drawing.
Who can draw blood from a port?
Blood draws via implanted ports may be performed by RNs trained in implanted port care. 3. This procedure shall be done using sterile technique and a non-coring needle.
Can they draw blood from your hand?
Only use the top of a hand for puncture. Veins on the palmar surface of the wrist, the fingers, and the lateral wrist above the thumb to the mid-forearm must not be used according to the 2017 CLSI standards. This will prevent the inadvertent puncture of hidden arteries, tendons, or nerves in the area.
Does IV go in artery or vein?
IVs are always placed in veins, not arteries, allowing the medication to move through the bloodstream to the heart. Learn more about IVs by reading 10 Commonly Asked IV Therapy Questions.
What is the alternative if IV line is not possible?
There are a number of therapeutic options for fluid administration in patients who lack usual venous access. Ways to establish this access include limb elevation and wrapping, the application of nitroglycerin ointment to dilate veins, and blood pressure cuff inflation.
Can we draw blood from cannula?
Guidelines recommend blood samples from peripheral intravenous cannula be taken only on insertion. Anecdotal evidence suggests drawing blood from existing cannulas may be a common practice.
Why do PICC lines stop drawing blood?
Excessive force could cause a flexible PICC to temporarily collapse and occlude the backflow of blood. On a peripheral vein, you could be pulling the vein wall over the catheter lumen as in this drawing.
Can blood be drawn from a single lumen PICC line?
A single lumen PICC has one tubing and one cap on the end. A double lumen PICC has two separate tubings and two caps. A PICC is used to give medications, fluids and IV nutrition. If the PICC is big enough, it can be used to draw blood.
Can a phlebotomist draw from a port?
A nurse or phlebotomist must be trained in the correct method of cleaning or flushing a port before it can be used. Some clinics and hospitals require a healthcare provider’s order authorizing the use of a port for a blood draw.
Can you draw blood from a TPN line?
Because TPN is lipid-rich and tends to stick to catheters, collection of blood specimens from the same lumen of a catheter used to administer the solution is best avoided.
Can you draw a VBG from a central line?
The role of venous blood gas samples in the evaluation of oxygen delivery is discussed below. The preferred method for assessment for assessment of acid-base balance is to draw the sample from a central venous catheter. A central venous catheter provides a broader reflection of systemic pH than a peripheral stab.
Can you draw PTT from arterial line?
Conclusion: We recommend that when drawing prothrombin time and activated partial thromboplastin time samples from an arterial line, a 5.3-mL discard volume be used.
Can you get blood through a port?
A port-a-cath is used to give intravenous fluids, blood transfusions, chemotherapy, and other drugs. It is also used for taking blood samples. A port-a-cath may stay in place for a long time and helps reduce the need for repeated needle sticks.
Can you give blood through a port?

Where should you not put an IV?
The catheters are for peripheral use and should be placed where veins are easy to access and have good blood flow, although the easiest accessible site is not always the most suitable. “Avoid inserting the IV catheter close to a flexible joint where it may bend.
What happens if you accidentally inject into an artery?
Hitting an artery can be painful and dangerous. Arterial blood travels away from the heart so whatever is injected goes straight to body limbs and extremities. Injection particles get stuck in blood capillaries and cut off circulation. This can result in a lack of blood flow, eventually causing the tissue to die.
What veins can be used for IV?
The preferred sites for IV cannulation Hand. Dorsal arch veins. Wrist. Volar aspect. Cubital fossa. Median antecubital, cephalic and basilic veins. Foot. Dorsal arch. Leg. Saphenous vein at the knee.
What happens if IV is not in vein?
When left unchecked and untreated, IV infiltration can result in pain, swelling, compartment syndrome, and even amputation of the affected limb.
Why is tapping of the vein not recommended?
Light tapping of the vein may be useful but can be painful and may result in the formation of haematoma in patients with fragile veins (Dougherty, 1999). ‘Smacking’ the vessels may cause histamine release.
What are the 3 main types of IV fluids?
There are three types of IV fluids: isotonic, hypotonic, and hypertonic. Isotonic Solutions. Isotonic solutions are IV fluids that have a similar concentration of dissolved particles as blood. Hypotonic Solutions. Hypotonic solutions have a lower concentration of dissolved solutes than blood. Hypertonic Solutions.
