Why do you angle the needle for insertion into the vein?

Because the goal of the procedure is to place a plastic catheter into the vein. If you insert the needle/catheter vertically you will go through the vein. If you angle on insertion once placement in the vein is confirmed you can slide the hollow catheter off of the needle into the vein. The veins used for most IV's normally lie just under the skin. For this reason a shallow angle of insertion is used.

How do you start an IV in a dog?

Most veterinarians first try to place an IV catheter in the front leg, in the superficial vein that runs over the metacarpal bones of the lower forelimb. With a dog in sternal recumbency (lying on his chest bone), you would take your non-dominant hand and use the thumb to apply pressure both down and laterally to stabilize the vein and occlude it so it fills with blood and becomes easier to see. In long-haired dogs, you may need to use some isopropyl alcohol on the area to wet the hair down and allow you to see the vein. In most practices, a technician or assistant will restrain the dog and 'roll the vein' for the veterinarian or technician placing the catheter - this allows the veterinarian to control the paw and increase the venous blood pressure through squeezing the paw. Once you can visualize the vein, place the point of the IV catheter against the skin so that you can see the opening in the needle tip. Firmly and smoothly drive the catheter forward, breaking the skin and the wall of the vein and feeding the IV cathether down the vein. Once the catheter tip is in, release the downward pressure on the vein to allow blood flow to resume; otherwise you end up with a bloody mess and can blow the vein out. Use narrow strips of medical tape to secure the catheter in place and attach fluids or whatever need injecting to the catheter.

What is the medical term meaning surgical incision into a vein?

Phlebotomy.phlebotomyphlebotomyIn Medical and Surgical terminology a surgical incision into a vein is called venesection. Another type of vein surgery, called ambulatory phlebotomy, creates an extremely small incision in the skin by the vein. A hook is then inserted through the tiny incision and is used to remove the vein.Laser surgery is often performed when the vein is too small to inject or remove. Light energy is sent into the vein in short bursts, slowly shriveling the vein. The vein then disappears over a small period of time. Laser surgery is very accurate and usually safe for all skin types.One particular vein surgery that can be done inside the doctor's office and usually has a person back to their normal daily activities within one day is called entravenous laser therapy (EVLT). This process involves inserting a tiny laser fiber into the vein where it closes the vein by sending pulsating lasers through it. This treatment is sometimes used in conjunction with other vein surgeries.The VNUS Closure, also known as radio frequency vein ablation, is an alternative treatment that can be performed on an outpatient basis. When a patient undergoes this procedures, an diagnostics ultrasound shows the doctor where to place a catheter inside the vein. Once the catheter is inside the vein, radio frequencies are used to heat the vein and shrink the walls, thus closing the vein. The blood is then rerouted through other healthy veins.
