“It is not bleeding.”
Choi Moo-gyeol immediately lowered the lesion.
“It’s a brainstem traction response.”
The brainstem is the organ that coordinates functions essential to life, such as breathing and heartbeat.
Because it is a core organ where many nerves are concentrated, even a slight wrong touch during surgery causes a reaction.
Just now, the force with which Choi Moo-gyeol pulled the lesion was transmitted to the brainstem through the surrounding tissue.
When the brainstem is compressed like this, the trigeminal nerve or the cardiac reflex (TCR) is stimulated, which can cause an autonomic seizure.
Then the heartbeat can slow, or hypotension can occur, or in severe cases, even cardiac arrest.
Choi Moo-gyeol was able to quickly stop the hand that had been pulling the brainstem before a more severe reaction appeared, thanks to neural acceleration.
“Warm saline.”
Warm irrigation fluid entered the surgical cavity.
Cha Jeong-han also prepared drugs…
