If you feel suffocating, use thiopental sodium for intravenous anesthesia first and then give succinylcholine

Overdose leads to respiratory muscle paralysis

Rescue: acidified body fluids, ventilator

Extraocular skeletal muscles contract briefly and intraocular pressure increases

Sustained depolarization of muscles releases potassium ions and increases blood potassium

Elevated serum potassium induces cardiac arrest

genetic disease

Rescue: Cool down, inhale oxygen, correct acidosis, use dantrolene to inhibit the release of calcium ions from the sarcoplasmic reticulum, and antihistamine

Increase gland secretion and promote histamine release

The muscles of the eyes, limbs, neck, and trunk relax in sequence, and then the intercostal spaces relax, resulting in abdominal breathing.

Increased doses may cause diaphragm paralysis and respiratory arrest.

The order of recovery is opposite to that of muscle relaxation.

Promotes histamine release, manifested by histamine-like rash, bronchospasm, hypotension, salivation

Partial inhibition of adrenal medulla secretion, resulting in lower blood pressure
