Do you mean general anesthesia (GA)? Which context are you asking about?
- Fasciculations: brief muscle twitching, often visible in the legs, after giving succinylcholine.
- Tourniquet sign/test: used to isolate a limb during regional anesthesia or assess circulation.
- A sign of anesthesia depth or nerve block?

succinylcholine fasciculations visible legs during induction general anaesthesia
The sign seen in the legs after giving general anesthesia with succinylcholine (suxamethonium) is muscle fasciculation.
- It appears as brief, fine, visible twitching or rippling of muscles, often noticed in the legs, abdomen, chest, or face.
- It occurs because succinylcholine initially depolarizes skeletal muscle before producing paralysis.
- It is followed by flaccid paralysis, which facilitates endotracheal intubation.
This is called the fasciculation phase of a depolarizing neuromuscular blocker. Miller’s describes succinylcholine as producing fasciculations, which may be reduced by prior administration of a small dose of a nondepolarizing relaxant. - Miller’s Anesthesia, 10e
A recent meta-analysis also addresses prevention of succinylcholine-induced fasciculation and muscle pain (PubMed record).
