Peripherally inserted central catheter
Urokinase may be used to lyse obstructions. When done at bedside, (that is, in the patient s room), a suitable sterile field must be established and maintained throughout the procedure.CVP is a rough estimate of the right atrial pressures of the heart and can give valuable information about fluid status of the patient. PICC insertion is a sterile procedure, but does not require the use of an operating room. Commonly, other forms of intravenous access are considered if the treatment course is protracted.
While replacement is generally considered a year post-insertion, patients have survived with the same PICC in situ for several years without complication. Certain types of PICCs have recently been approved by the FDA for use in power injection. Complications may include catheter occlusion, phlebitis, hemorrhage, thrombosis and infection.
PICC lines generally will remain in place no longer than 30 days, although duration of use varies from just a few days in patients requiring short courses of chemotherapy or biotherapy to a year for patients requiring longer treatment. Usually, a smaller adhesive bandage can be placed over the wound site after the gauze is removed if the wound is slow to heal. .
Other new technologies which may provide advantages are being introduced to the market such as the SecurAcath subcutaneous securement technology. for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition).
As supplied, the line has a guide wire inside. Subclavian and internal jugular line placements may result in pneumothorax (air in the pleural space of lung). A PICC is inserted in a peripheral vein, such as the cephalic vein, basilic vein, or brachial vein and then advanced through increasingly larger veins, toward the heart until the tip rests in the distal superior vena cava or cavoatrial junction. PICCs are usually inserted by radiologists, physician assistants (in the USA), radiologist assistants (in the USA), or specially trained certified registered nurses using ultrasound, chest radiographs, and fluoroscopy to aid in their insertion and to confirm placement.
Securing the catheter prevents post-insertion movement of the line, as that could place the tip in an unsafe position. PICC line can also be used to measure the CVP (Central Venous Pressure). Some lines are designed to be trimmed to the desired length before insertion, others are simply inserted to the needed depth with the excess left outside.
The wire is removed and discarded after insertion. The PICC is also provided with a wing having holes for either sutures or an adhesive securement device such as Statlock. After removal, the insertion site is normally bandaged with sterile gauze and kept dry for a few days, during which the wound can close and begin healing.
For this reason, visitors are normally requested to leave the room until the insertion is complete. Removal of a PICC line is a considerably more simple procedure in most cases. First described in 1975, it is an alternative to subclavian lines, internal jugular lines or femoral lines which have higher rates of infection.
A peripherally inserted central catheter (PICC or PIC line) is a form of intravenous access that can be used for a prolonged period of time (e.g. Generally, the catheter line can be safely and quickly removed by a trained nurse, even in the patient s own home, in a matter of minutes.
This wire is provided to stiffen the (otherwise very flexible) line so it can be pushed through the veins. These PICCs, often referred to as power injectable PICCs, are designed to withstand the high pressures associated with radiocontrast studies. The insertable portion of a PICC varies from 35 to 55 centimeters in length, that being adequate to reach the desired tip position in most patients.
