Intravenous push injections require pre-injection preparations such as tying a tourniquet, disinfecting the skin, puncturing a venous vessel with a syringe needle, feeding the medication in, and finally withdrawing the syringe and swabbing it to stop the bleeding. Intravenous push, a method of administering medication through a vein using a syringe with a small amount or a single type of medication, requires a healthcare professional to perform the procedure. The doctor or nurse will use an intravenous needle with a syringe, and can prepare the medication, which is a relatively small dose and is required to be injected over a certain period of time, by using a rubber tourniquet to tie off the area to be injected. Find the location of the vein vessel and sterilize the skin properly. Using a syringe needle to pierce the skin above the patient’s venous vessels, gently push the handle of the syringe, and release the tourniquet when venous blood is found to be flowing back into the syringe, and inject the medication. For example, with general anesthesia drugs, the drug is given before anesthesia. Patients with hypoglycemia may be given high concentrations of glucose by intravenous push during an attack of the disease, for example.
