Do beta blockers interfere with anesthesia?
Bradycardia, hypotension and bronchospasm are the main hazards in BB treated patients undergoing anaesthesia. However giving BB with premedication to patients taking usely this treatment allows better perioperative haemodynamic stability and avoids rebound effect.
What are the dangers of beta-blockers?

Why is metoprolol used after MI?
The METOCARD-CNIC trial (Metoprolol in Cardioprotection During an Acute Myocardial Infarction) demonstrated that the intravenous administration of metoprolol during ongoing anterior STEMI reduces the size of infarction,10 reduces the presence of microvascular obstruction and reperfusion injury,11 and improves long-term …
When do you give metoprolol IV?

Titrate gradually as needed for clinical effect; heart rate may be dose-limiting.
Which is the safest beta blocker?
A number of beta blockers, including atenolol (Tenormin) and metoprolol (Toprol, Lopressor), were designed to block only beta-1 receptors in heart cells. Since they don’t affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders.

- Atenolol (Tenormin)
- Betaxolol (Betoptic eye drops, Kerlone tablets)
