Pediatric convulsions are involuntary contractions of generalized or localized skeletal muscles with or without impairment of consciousness due to a sudden and massive abnormal discharge of neurons in the brain. It is one of the common acute symptoms in pediatric patients. Typical manifestations are loss of consciousness, staring, squinting or upward turning of both eyes, head turning to the side or tilting back. The muscles of the face and limbs are paroxysmal or tonic twitching. The laryngeal muscles are spasmodic and the airway is not open, so the face and the perioral cyanosis are visible. Some children have urinary and fecal incontinence. Generally, the convulsions stop by themselves after a few seconds or minutes, and then enter a state of lethargy. A few patients have convulsions and then have another convulsion before they wake up; and not many neonates have generalized convulsions, often only one side of the limb jumping, tonicity, jaw shaking, frequent blinking, and both eyes staring.
