Perioperative Cardiac Complications — Flashcards

Flashcard 1: The most common anaphylactic agent during anesthesia is _____

Answer: antibiotics

Flashcard 2: Cardiac arrhythmia is an _____ sign of malignant hyperthermia

Answer: early

Flashcard 3: _____ is the mainstay rx for cardiac arrest due to bupivacaine

Answer: Intravenous Lipid Emulsion (ILE) / Intralipid

Extra: Lipid Emulsion Therapy (20% Intralipid) is the mainstay for cardiac arrest due to Local Anesthetic Systemic Toxicity (LAST), specifically bupivacaine. Note: Standard ACLS is modified in LAST. Avoid vasopressin and use only low-dose epinephrine (<1 mcg/kg), as high doses can impair resuscitation and reduce the efficacy of lipid emulsion.

Flashcard 4: Drug of choice for ventricular arrhythmias induced by bupivacaine

Answer: Lipid emulsion therapy

Flashcard 5: The following capnography waveform represents: _____

Answer: malignant hyperthermia

Flashcard 6: The following capnographic waveform is suggestive of _____:

Answer: Malignant hyperthermia

Flashcard 7: Tuberculin syringe 1ml or insulin syringe _____units, without fixed needle x3 are one of the components of the anaphylaxis kit

Answer: 40

Flashcard 8: Malignant hyperthermia is usually related to a defect in _____ receptors, which causes increased Ca2+ release from the SR

Answer: ryanodine

Flashcard 9: Propofol infusion syndrome is seen when the dose of propofol infusion is greater than _____ mg/kg/hour for 48 hours or longer

Answer: 4

Flashcard 10: Masseter spasm is an _____ sign of malignant hyperthermia

Answer: early
