Drug contraindicated in patient with rheumatic hea disease in PPH is
**Core Concept**
Rheumatic heart disease (RHD) often involves mitral stenosis, which can lead to pulmonary hypertension and right heart failure. In the setting of postpartum hemorrhage (PPH), a patient with RHD may be at risk for cardiac decompensation due to the increased workload on the heart.
**Why the Correct Answer is Right**
The correct answer is ergot alkaloids, specifically ergometrine. Ergot alkaloids work by inducing sustained uterine contractions, which can lead to a significant increase in cardiac workload, potentially exacerbating pulmonary hypertension and right heart failure in a patient with RHD. This is particularly concerning in the setting of PPH, where the patient may already be at risk for cardiac decompensation.
**Why Each Wrong Option is Incorrect**
* **Option A:** Oxytocin is a safe choice in PPH, even in patients with RHD, as it induces uterine contractions without significantly increasing cardiac workload.
* **Option B:** Methergine is another ergot alkaloid with similar properties to ergometrine and is contraindicated in patients with RHD.
* **Option D:** Carbetocin is a long-acting oxytocin analog that is safe to use in patients with RHD.
**Clinical Pearl / High-Yield Fact**
In patients with RHD, it's essential to choose uterotonic agents that do not significantly increase cardiac workload, such as oxytocin or carbetocin. Ergot alkaloids, including ergometrine and methergine, should be avoided in these patients.
**Correct Answer:** C.
