Adrenaline used for controlling of bleeding during surgery may result in________________?
Correct answer: B. Cardiac arrhythmias
- A. Syncope
- B. Cardiac arrhythmias
- C. Drastic fall in blood pressure
- D. Precipitation of allergic reaction
Explanation
Adrenaline stimulates cardiac beta-1 receptors and can increase automaticity and conduction, making cardiac arrhythmias a risk during surgical use. It generally raises rather than drastically lowers blood pressure and is not primarily used to precipitate allergy.
