Experiment 1a - Intravenous (IV) Injection Decamethonium

Info

After establishing a control response 0.02 mg/kg of DECAMETHONIUM is injected intravenously.

Task

Describe the change in twitch tension immediately following injection but before appearance of the block.

 TrueFalse 
Tubocurarine causes a reversible decrease in twitch tension
Decamethonium produces an initial increase in twitch tension followed by a reversible decrease
Tubocurarine produces a peak fall in twitch tension of about 75%
The pattern of the response to decamethonium is the same as that for tubocurarine
