Apatient of A prolonged immobilisation in ITU. Patient developed sudden severe tricuspid regurgitation, immediate management ?
**Core Concept**
Prolonged immobilization in an Intensive Care Unit (ITU) patient can lead to a condition known as **Immobilization-Induced Tricuspid Regurgitation (IITR)**. This occurs due to the formation of a **tricuspid valve flail leaflet**, causing severe tricuspid regurgitation.
**Why the Correct Answer is Right**
The immediate management of IITR involves the administration of **intravenous furosemide** to reduce right ventricular preload and alleviate the regurgitant volume. This helps in decreasing the tricuspid valve annular diameter, thereby reducing the severity of regurgitation. The use of furosemide also helps in reducing fluid overload and subsequent right ventricular dilation.
**Why Each Wrong Option is Incorrect**
**Option A:** Administering nitrates would increase venous capacitance, potentially worsening right ventricular preload and tricuspid regurgitation.
**Option B:** Starting an inotrope like dobutamine may increase right ventricular contractility, but it does not address the underlying issue of tricuspid valve flail and regurgitation.
**Option C:** Performing an emergency tricuspid valve repair or replacement surgery is not immediately necessary in this scenario and may not be feasible in an ITU setting.
**Clinical Pearl / High-Yield Fact**
In patients with prolonged immobilization, IITR can occur due to the formation of a tricuspid valve flail leaflet. Early recognition and management with intravenous furosemide can help alleviate symptoms and prevent further complications.
**Correct Answer: A. Furosemide**
