SUX

Question 1

Sux - Class (1)

Answer 1

• neuromuscular blocker (ACh depolarizing)

Question 2

Sux - Action (2)

Answer 2

• Binds w/ cholinergic receptors on skeletal muscle (and diaphgram) fibers that depolarizes it and causes fasciculations- Releases Histamine

Question 3

Sux - Indications (3)

Answer 3

• Facilitate RSI- Terminating Laryngospasms- Muscle Relaxant

Question 4

Sux - Contraindications (5)

Answer 4

• Hx of malignant hyperthermia- skeletal muscle myopathies- airway anatomy makes intubation unlikely- hypersensitivity- Acute Rhabdomyolysis (Cell membrane blocked from K uptake)

Question 5

Sux - Side Effects (6)

Answer 5

• Initial muscle fasciculation- malignant hyperthermia- may exacerbate hyper K in post trauma crush injury, burn and paralyzed limb- excessive salivation- hypotension- bradycardia
