Anesthesia for Interventional Cardiology — Flashcards

Flashcard 1: The most effective circuit for anesthesia under controlled breathing is Mapleson _____

Answer: D (Bain circuit)

Extra: Efficiency of Mapleson circuits: - **Controlled ventilation**: D > E > F > B > C > A - **Spontaneous ventilation**: A > D > E > C > B

Flashcard 2: **Venturi masks** (and anesthesia breathing circuits) are _____ flow fixed performance systems

Answer: high

Flashcard 3: In the ACLS algorithm for VF/pVT, which medication is administered every 3-5 minutes starting after the second shock?

Answer: Epinephrine

Flashcard 4: The definitive treatment for post-dural puncture headache (PDPH) is an _____.

Answer: epidural blood patch

Flashcard 5: The intravenous induction agent of choice in circulatory failure or hypotension is _____

Answer: ketamine

Flashcard 6: Which type of anesthesia is preferred for the management of a patient with severe **post-partum hemorrhage** and hemodynamic instability?

Answer: General anesthesia

Extra: General anesthesia (GA) is the technique of choice in the presence of hypovolemic shock because neuraxial anesthesia (spinal/epidural) causes sympathectomy, which can lead to profound, life-threatening hypotension. **Note on Inhalational Agents:** Volatile anesthetics (like Sevoflurane or Isoflurane) are potent uterine relaxants. While this is beneficial for manual removal of a retained placenta or uterine inversion, these agents should be used at very low concentrations (<0.5 MAC) if the PPH is due to uterine atony to avoid worsening the hemorrhage.

Flashcard 7: _____ is the most commonly used depth of anesthesia monitor.

Answer: Bispectral index
