Study Notes
Medication Management
- Labetalol is the drug of choice for Posterior Reversible Encephalopathy Syndrome (PRES) due to its alpha- and beta-blocking effects.
- In the absence of labetalol, nicardipine can be used as a substitute to lower blood pressure.
Hypertensive Emergencies
- The infusion rate of labetalol when administered intravenously to lower blood pressure is 2-8 mg/min.
- Sublingual nitroglycerine (NTG) can cause a potential rebound effect, leading to increased blood pressure in hypertensive emergencies.
Shock Management
- Hypovolemic shock is considered incorrect in decompensated shock because it does not consider other types of shock (e.g., cardiogenic, obstructive, and distributive).
- The recommended treatment approach for a patient in compensated shock is to optimize volume status and vasopressor support before considering pressor options like dopamine.
- Dopamine is preferred for managing cardiogenic shock due to its positive inotropic effects and minimal effects on peripheral circulation.
Aortic Aneurysm
- A common mistake when considering the management of aortic aneurysm is failure to consider other diagnoses that may mimic its symptoms.
Legislation and Regulations
- The Comprehensive Drug Abuse Prevention and Control Act classified potentially abused medications into five schedules.
- The Federal Food, Drug, and Cosmetic Act (FD&C Act) gave authority to oversee the safety of food, drugs, and cosmetics in the United States.
- Nitroglycerine reduces blood pressure due to its vasodilatory effects.
