Route of Injection

Intravenous drip

It is the direct drip of a large amount of fluid into a vein. That is, after puncturing the vein, the medication is continuously dripped into the vein from a sling bottle through a Murphy's drip bottle and rubber tubing. It can be used to input drugs (such as antibiotics, sulfonamides, anticancer drugs), nutritional fluids, blood and its preparations, to replenish blood volume, maintain acid-base and water-electrolyte balance, supply nutrients and medicines, dilute toxins, reduce cranial pressure and so on. Generally, the needle should be removed after 12 to 16 hours of daily drip, and the infusion should be repeated on the next day; prolonged infusion can lead to superficial vein embolism. If a long period of infusion is needed, then there should be a plan to use the distal vein of the limb first, and then to the proximal end of the choice of veins to use, in order to avoid superficial vein blockage, can be incised or puncture the deep vein after the intravenous drip. Commonly used methods include incision of the saphenous vein or puncture of the femoral vein or subclavian vein, followed by placement of a flexible catheter, so that the infusion can continue for a longer period of time, avoiding daily puncture. However, long-term stimulation of local blood vessels by the catheter tip can also lead to vascular inflammation and occlusion, so the catheter should be pulled out 2-3MM every 5-7 days.Intravenous blood transfusion is similar to infusion but with a thicker needle. Intracorporeal injection uses a syringe to inject drugs into each body cavity for treatment. Commonly used intracerebroventricular injection, intrathecal injection, intrapleural cavity injection, artificial pneumothorax, pneumoperitoneum for the treatment of tuberculosis, intraperitoneal injection, intra-articular cavity injection.
