Abstract:
Left ventricular unloading during extracorporeal life support aims to minimize potential side effects of increased left ventricular afterload. A transaortic catheter vent implanted through a subclavian approach was used in 2 patients. Patient 1 was a 48-year-old man with a recent history of ST-elevation myocardial infarction who developed refractory cardiogenic shock due to severe biventricular dysfunction. Patient 2 was a 56-year-old man admitted for severe flu. The unloading procedure was successful in both patients, with bridge to heart transplantation in the first case and bridge to recovery in the other.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.

Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
