Description

Neuromuscular Blockade:

- Facilitates intubation

- Facilitates better surgical conditions

- Facilitates mechanical ventilation (i.e. ARDS, hyperventilating in increased ICP)

Two Categories: 

- Depolarizing: ex. Succinylcholine (1-1.5mg/kg IV) depolarizes the muscle and prevents repolarization.

- Non-depolarizing: ex. Rocuronium (0.6-1.2mg/kg IV) Outcompetes ACh for the receptor on the endplate.
