For long term treatment of ailments such as diabetes, cancer, TPN, lyme disease, or just about any condition that requires regular intravenous medication and blood drawing for tests, the doctor may recommend a peripherally inserted central catheter or PICC line. This is a line inserted into a peripheral vein and advanced into a larger vein near the heart. The PICC line (catheter) insertion is done by a doctor with the help of a sonogram or a similar imaging device. The patient may be administered a local anaesthesia to ease the process. PICC insertion prevents the need for multiple needle pricks over the course of treatment. It may be left in place for weeks and even up to 18 months at a time and allows one to perform all regular activities. The patient is given complete PICC care instructions by the doctor who performs the insertion.
