Infection, bleeding or pneumothorax are complications that can occur if the intravenous catheter is placed incorrectly. Currently, placing a central venous catheter under ultrasound guidance offers many outstanding advantages, limiting the risk of complications.

Placing a long line to the central vein from the periphery helps to nourish the veins in newborns, especially premature babies, as well as to treat venous diseases of relatively small children. This method is mainly used in emergency resuscitation.

Nutrients such as glucose, proteins and fats when given directly into the blood through a vein is called parenteral nutrition. This is an alternative method of feeding premature babies with immature digestive systems or serious illnesses.

The choice of central venous catheter placement depends on the indication, anatomy, and other patient factors. In clinical practice, central venous catheter placement is a necessary procedure, especially in intensive care units.

Intravenous chemotherapy is a method of introducing chemicals into the patient's body through the vein to destroy cancer cells. During the chemotherapy process, the patient needs to be closely monitored for possible complications, especially in the first 30 minutes.
