The clinical manifestations of neonatal convulsions

Clinical will be divided into minor convulsion, limitations clonic type, multifocal clonic type, ankylosis type, type, and other systemic myoclonic five types. (1) Low - The most common neonatal convulsions types, Performance for staring, strabismus, the blink of an eye movement, sucking, chewing-like mouth - cheek - tongue movement, a single limb tremor, fixed or limbs or rowing-like movement, as well as apnea and other attacks. (B) limitations clonic type To ipsilateral limb limitations of single - or dual-clonic tic features, but no positioning sense, and more without loss of consciousness. More common in premature infants. (C) type of multifocal clonic A small number of physical amplitude, frequency 1 ~ 3 times / sec for the characteristics of the side limbs can be physically transferred to the other side, many accompanied by loss of consciousness. Common in intracranial disease or certain metabolic disorders. (D) Type ankylosis For the whole body or limbs, ankylosing spasm (extension or rigid). Suggested that serious condition, organic brain disease, and to be brain tonic and anti-angle arch-differential. Performance to the brain tonic for the limbs and trunk extension, Lai Xuan in the upper extremity, pupil scattered, moving down two eyeball, often terminal brain failure signs. Kok arch anti-exaggeration to back continued after the arch, seen bilirubin encephalopathy, tetanus and certain amino acid metabolic disorder. (5) myoclonic Single or multiple limbs to synchronization, symmetry is characterized rapid buckling cramps, lower limb upper extremity than obvious. Indicated that a diffuse brain damage. These five categories, to minor-common (or seizure of 50 percent), followed by multifocal spastic. Also in recent years under the EEG monitor multiple images of the neonatal convulsions divided into: ① clinical attack with the EEG signal - to; ② attack without clinical EEG signal; ③ of infantile spasms. The clinical manifestations of neonatal convulsions usually amorphous and changeable type of attack, sustained varying duration of a particular site or frequently manifests itself physically, the tic head and face, or eye fixed, blink, or even stretching limbs ankylosing . According to the original differences in the incidence of fever or body temperature does not rise, cyanosis, unconsciousness, the former囟plump, jaundice, and other symptoms and signs. Neonatal seizures continued more than 30 minutes, known as neonatal convulsions status.
