Inject Right Medication Through Central Venous Access

In the field of medical, the central venous access refers to the treatment procedure under which a catheter is placed into a large vein in the neck, chest or groin. It is also called central venous catheter (CVC) that is used to administer medication or fluids, obtain blood tests and to gain cardiovascular measurements like central venous pressure. Some specific medications like inotorpes and amiodarone can be given through this tube.

Central line placement can be performed when peripheral venous access is not possible. The dialysis fistulas and grafts may have high back pressure and require positive pressure to infuse. The heparin in some catheters is an extremely high concentration that will be detrimental if it enters central circulation. The catheter is monoluminal, biluminal or triuminal, dependent on the actual number of tubes or lumens. It usually held in place a stature or staple and an occlusive dressing. Certain lines are imbued with antibiotics, silver-containing substances and chlorhexidine to eliminate any infection risks.

There Are Some Common Procedures Adopted Under The Central Venous Access Treatment, Such As-


1.    Physicians have to prepare equipment in advance.
2.    Identification of the standard prehospital equipment (implanted ports, AV fistulas, non-coring needle and grafts should be accessed by special).
3.    Access the device after cleansing with betaline prep.
4.    Discard aspirated medical fluid.
5.    Establish IV connection to avoid air entry.
6.    Secure with Luer lock or tape
7.    Flush lumen or port with 10 cc saline to avoid excessive pressure.

A central venous access procedure involves X-ray and ultrasound technologies and a guide wire. The equipments that are typically used for this treatment include radiographic table, x-ray tube and a computer system to view images in real time. The still pictures can be captured electronically.
