Pediatric convulsions are involuntary paroxysmal strong contractions of generalized or localized muscles in children. Convulsive seizures can manifest as tonic, clonic and mixed. Tonic is mainly a continuous contraction of the whole body or local muscles; clonic is mainly an intermittent contraction of the whole body or local muscles; mixed is a succession of tonic and clonic contractions of the whole body or local muscles. Generalized tonic convulsions generally have the following manifestations: confusion, tonic limbs, generalized corkscrew, eyes staring, and call may be accompanied by foaming at the mouth, incontinence, and cyanosis around the mouth, etc. Restricted twitching is only a local muscle twitching symptom in the body, and the mental performance is mostly unclear, which can be manifested as one side of the limb twitching, or simple finger and toe twitching, and the eyes can be accompanied by staring, or frequent blinking of both eyes, or just showing eye rotation or nystagmus. The duration of twitching varies, sometimes only a few seconds or a few minutes, but serious twitching can last for more than ten minutes or half an hour, or there are repeated twitching episodes.
