This course gives you a clear, clinically focused review of calcium channel blockers in the perioperative setting—what they do at the L-type calcium channel, how dihydropyridines differ from non-dihydropyridines at the bedside, and why that matters for your anesthetic plan. You’ll walk through practical implications for managing hypertension, rate control, and myocardial ischemia around the time of surgery, as well as toxicity, drug–drug interactions, and key contraindications (including malignant hyperthermia considerations). By the end, you’ll be better equipped to anticipate hemodynamic responses in patients on CCBs and to integrate these agents safely into comprehensive anesthetic management.
