One of the treatment modalities for most of these diseases is medical treatment or medication. Medicines have many benefits in curing diseases, but besides that, if used improperly and inappropriately, they can cause harm to the patient's body. In particular, for intravenous antibiotics, it is necessary to pay attention to the position of intravenous injection, injection technique, drug dose... to limit unwanted consequences.

Intravenous injection is one of the basic injection techniques and is commonly used in medicine today. This technique has the advantage of delivering the drug directly into the circulatory system, helping the drug's effects to take effect quickly. However, intravenous injection is not always possible.
