How many receptors are in the Somatic Nervous System? 1 Nicotinic II Receptor
What is the single neurotransmitter with Somatic Nervous System? Acetylcholine (Ach)
What does Acetylcholinesterase do? Terminates Neurotransmitter (Ach) and allows repolarization
What terminates Acetylcholine? Acetylcholinesterase
Peripheral Acting Drugs are administered through.... IV (Intravenous)
T/F Peripheral Acting Drugs are Dose Dependent? True
Peripheral Acting Drugs does what? Interferes with N2 receptors at the muscle
What are the two types of Neuromuscular Blockers? Non-depolarizing & Depolarizing
Which type of Neuromuscular Blocker can be reversed with an antidote? Non-depolarizing Blocker
Which type of Neuromuscular Blocker can NOT be reversed with an antidote? Depolarizing Blocker
How is both Depolarizing and Non-Depolarizing administered? Injection or IV
Onset of Non-depolarizing N/M Blocker? 3-5min
Duration of Non-Depolarizing N/M Blocker? 20-30min
T/F Non-depolarization is an antagonist? True
What does Depolarizing Neuromuscular Blockers do? Stimulates N2 receptor then blocks it
Non-Depolarizing Neuromuscular Blockers can cause..... Malignant hyperthermia/Spike Potassium levels/Fasciculations
T/F Depolarizing is fast acting? True
T/F Non-Depolarizing is fast acting? False
Depolarizing Neuromuscular Blockers can cause..... Contractions then N2 receptor is blocked
ALWAYS give what with paralytics? Analgesics (pain meds) & Sedatives

Train of Four is used.... To asses the degree of paralysis
What is the process of Train of Four? (2 Step Process) (Step 1) A small electrical device gives a micro-electrical shock to the hand. (Step 2) Count the # of twitches EX. 4 twitches= <75% block & 3 twitches= 90% block & 2 twitches= 95% block & 1 twitch= 98% block
What is significant to remember with use of Train of Four. The patient should be reversed to have some movement every 24hrs to reduce possible long term complications.

Norcuron is also known as what? Vercuronium
Zemuron is also known as what? Rocuronium
What is best known for Norcuron and Zemuron as Non-Depolarizing NM Blockers? They are known to have few or low incidence of adverse cardiovascular effects
