#### Monitoring

The BNF advises to monitor lung function (in patients with a history of obstructive airway disease).

#### Overdoses

Overdosages with beta-blockers may cause cardiac effects such as bradycardia, hypotension, syncope, conduction abnormalities, and heart failure. Bradycardia is the most common arrhythmia, but some beta-blockers may induce ventricular tachyarrhythmias secondary to prolongation of QT interval (e.g. sotalol) or QRS duration (e.g. propranolol).
Non-cardiovascular effects include central nervous system effects (including drowsiness, confusion, convulsions, hallucinations, and in severe cases coma), respiratory depression, and bronchospasm.

Management
 - Airway protection 
 - Activated charcoal within 1 hour
 - IV Fluids
 
IV glucagon is the first-line management.
 
For symptomatic bradycardia, IV atropine may be used.

1st hour = 10mmol KCl
Next 2 hours = 20mmol KCl
Next 2 hours = (2/8 x 40mmol KCl) = 10mmol KCl

Total dose of potassium in 5 hours
= 10 + 20 + 10 mmol KCl
= 40mmol KCl

mmol
A 55-year-old gentleman is admitted to Surgical Assessment Unit with likely acute pancreatitis. Following surgical review, he has been kept NBM and IV fluid has been prescribed. Weight 80kg.


His IV fluid regimen has been prescribed as below:

* IV 0.9% Normal Saline 500mL 10mmol KCl over 1 hour
* IV 0.9% Normal Saline 1L 20mmol KCl over 2 hours
* IV 0.18% Normal Saline 4% Dextrose 1L 40mmol KCl over 8 hours

What dose (mmol) of potassium will have been administered IV in the first 5 hours?
