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 I draw blood from a midline catheter?
Also, routine blood draws are not advised from a midline catheter, whereas they can be used from the other types of venous catheters. It is possible to draw from a midline catheter if very gentle pressure is applied and a specific technique is used.
Can you draw blood from central line?

Why can’t you draw blood from an IV?
Blood that is drawn from a vein that has an intravenous (IV) line may be diluted by the IV fluid. This can ultimately affect the accuracy of the blood test results. Therefore, an arm containing an IV should not be used to draw blood specimens if it can be avoided.

Frequent blood draws: PICC lines can be useful for drawing blood repeatedly, especially if you do not tolerate blood draws well yet require ongoing monitoring through blood tests.
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 you draw blood from a PICC with TPN?
Generally speaking you should not draw samples from a dedicated TPN lumen. If you have a single lumen PICC with TPN infusing you should perform a standard venipuncture. Always use syringes when drawing from a PICC as other devices are not recommended b/c pressure changes sometimes make it difficult to obtain specimens.
When drawing blood above an IV line you must?
The only coagulation test that can be drawn above an IV site is the prothrombin time. The infusion should be turned off for 10 minutes before obtaining this coagulation test.

What happens if an IV is started in an artery?
Complications of entering the artery with a large cannula intended for venous cannulation can result in complications such as temporary occlusion, pseudoaneurysm and haematoma formation. [6] Unrecognized arterial injection of anaesthetic drugs can cause tissue ischaemia and necrosis.
What happens if an IV is put in wrong?
When an IV is not inserted properly or is otherwise misused, fluids or medicine can leak into the surrounding tissue. This is called IV infiltration, and it can cause harm ranging from irritation to fluid overload, infections, nerve damage, stroke, brain injury, or even death.
