How long is a midline good for?
Midlines are routinely used for two to six weeks. Due that the extrem of these catheters does not extend beyond the axillary line, there are limitations for its use: type of infused drugs, velocity of infusion, etc. In general, solutions that have pH 5 to 9, or an osmolarity less than 500 mOsm are appropriate for infusion through a Midline.
How to insert midline catheter?
- Supine position
- Sterile skin prep (xiphoid area)
- 1% xylocaine local infiltration as needed
- A small puncture with a 11 blade knife on the skin just below and to the left of xiphoid process
- The long needle is positioned at 45º above the body surface and 45º to the right of midline
Is midline considered central line?
midline: A midline of a sinusoidal function is the horizontal center line about which the function oscillates above and below. For y = sin x, the midline is y = 0 (the x-axis). For example, y = sin(x) + 2 has a midline at y = 2.
Does midline need heparin flush?
Your midline lumen must be flushed to prevent infection and keep blood from clotting. Flush twice a day with heparin if not in use. The heparin syringes do not need to be refrigerated. Do not use force when flushing your catheter.

Why is a dressing important for a midline catheter?
The dressing holds it in place, keeps it clean, and helps prevent infection. The dressing will be clear so you can check the insertion site for signs of infection. Healthcare providers will watch for problems during the midline catheter placement. You could have bleeding when the catheter is inserted.
How to know if you have a catheter infection?
Check your skin every day for signs of infection, such as pain, redness, swelling, and oozing. Contact your healthcare provider if you see these signs. Change the dressing as directed.

Further research is needed to look at generalizability of placement at other institutions, time to placement and complication rates in comparison to central venous catheters.
What is a midline catheter?
MIDLINE CATHETER. The midline catheter is a vascular access that is also introduced on the upper arm – but has a maximum length of approximately 25 cm. The tip of the catheter lies in a peripheral vein before getting to the level of the chest.
Where is the midline catheter placed?
A peripherally inserted catheter that is commonly confused with a PICC is a midline catheter which is placed in a similar manner on the arm but whose tip terminates near the crease of the arm (Armpit) as opposed to a PICC. A Midline catheter is essentially a PICC that is cut short and whose tip is positioned somewhere in the arm prior to reaching the central veins near the heart. Midline catheters are generally not recommended because of the greater risk of thrombosis and venous thrombosis (DVT).
How long can a PICC line remain in place?
Therefore, the catheters are usually used for a therapy duration that is longer than 4 weeks.
How long can a midline catheter stay in place?
A midline catheter is a safe alternative to IV and can remain in place longer than conventional IV (recommended for treatments 5-28 days) but are generally reserved for patients who cannot get a conventional PICC or in whom treatment requires IV access for greater than 5 days where non-caustic medication is administered.
What is a PIC line?
A peripherally inserted central venous catheter ( PICC or PIC line), less commonly referred to as a percutaneous indwelling central catheter, is a form of intravenous (IV) access that can be used over a longer period of time (e.g. for long term chemotherapy, extended IV antibiotic therapy, or total parenteral nutrition ( TPN )) or for the administration of substances that should not be administered peripherally. Both PICC line and Midlines are catheters that enters into a peripheral vein usually on the arm through the skin (percutaneous), extends to the superior vena cava (a central vein near the heart), and can remains in place for days or weeks . First described in 1975, it is an alternative to central vein catheters which are placed through the main larger veins such as the subclavian vein, the internal jugular vein or the femoral vein in the neck and chest . The placement of subclavian and jugular lines have associated complications including a pneumothorax (air in the pleural space of the lungs), from inadvertent puncture of the lung while PICC lines have no such problem due to the method of placement.
Where is the PICC catheter inserted?
The PICC is inserted into a vein of the extremity ( basilic is generally preferred, cephalic vein, brachial vein or other veins of the upper extremity), the tip of the catheter ends in the central vascular system (e.g. superior vena cava as it transitions to the right atrium commonly referred to as the cavoatrial junction).
Where is the peripheral venous catheter placed?
Peripheral venous catheters are placed on the upper arm. The catheter is placed under ultrasound and using the Seldinger technique. Access into the upper arm vein is attained approximately midway between the elbow and the armpit.

What veins are used for midline?
The most suitable ones, related to the upper limb, are the basilic vein (usually the most indicated), the cephalic one or the brachial ve ins, depending on the characteristics of the patient. A Midline is used for intravenous treatments of more than 6 days, prolonged therapies (cardiological or antibiotic for serious infections), ...
Where is the PICC inserted?
PICC and Midline are both two peripheral insertion catheters, but while the first is inserted into the central venous system, the second remains - as mentioned above - at the level of the axillary or subclavian vein.
Can a cannula needle be used outside the hospital?
Unlike the cannula needle, it can also be used discontinuously and outside the hospital setting. The patient himself can be discharged from the hospital also with a Midline.
What is the advantage of a midline catheter?
