<unk> s of drugs were generally used only to provide emergency drugs to a patient if other approaches would be ineffective; for example if drugs could not be administered intravenously due to individual circumstances. The procedure is performed by inserting a long spinal needle into the ventricular chamber. The needle is inserted in the fourth intercostal space between the ribs. Today it is considered obsolete, and other routes to give drugs are preferred (i.e. via an endotracheal tube or intraosseous (direct in the bone))
Intracardiac injection
Intraosseous infusion
Intraperitoneal injection
Subcutaneous infusion
Machine perfusion
Intracerebroventricular injection
Intramuscular injection
Intracameral injection
