The first and last methods are the most common. Injections come in several types – intradermal, intramuscular and intravascular. The latter are the most difficult to perform, but the most quick and least painful for the person. For their performances, and needed IV fluids.Dropper is a device, usually made of plastic, consisting of a reservoir for the liquid and a needle connected by a long plastic tube for convenience of manipulation, as well as the valve regulating the rate and flow speed of the solution. The dropper is mounted on a tripod, the needle is inserted into vein or artery (depending on the administered drug). Sometimes a drip system consists only of tubes with a pin with a control valve and needle. Plastic pin stuck into the rubber stopper of a glass jar with a solution, put it on a tripod, set up the valve and perform the procedure.Often put intravenous fluids. This procedure has several features: first, it is important to check the IV before inserting the needle into a vein in the presence of bubbles of fluid – you should avoid them. Next, you need to treat skin disinfectant (alcohol pad). To avoid injury of the limb during manipulations, you need to drag it above the insertion of the needle the tourniquet and ask the person several times with force to compress and unclench the fist. This is necessary in order to make the muscle down, pushed the vessel to the skin, and it was possible to perform the procedure with minimal risk of damaging surrounding tissue.
