Head injury secondary to birth trauma  Carbamazepine (Tegretol) 2. Lead poisoning  Also used for Trigeminal neuralgia (Tic 3. Genetics Dolor) 4. Brain tumor  Phenobarbitals (Luminal) 5. Nutritional and metabolic deficiencies 4. Institute seizure and safety precautions 6. Sudden withdrawal of anti-convulsive drugs  Post-seizure:  Causes STATUS EPILEPTICUS  O2 inhalation  DOC: diazepam, glucose  Suction apparatus 7. Physical and emotional stress 5. Monitor and document the following  Onset and duration B. TYPES OF SEIZURES  Type of seizure 1. Generalized  Duration of post-ictal sleep  increased length of  Grand Mal (Tonic-Clonic) sleep can lead to status epilepticus  With or without an aura 6. Assist in CORTICAL RESECTION  Epigastric pain – initial sign of an aura (aura is an initial sign of seizures) For a one year old client suffering grand mal seizures:  Visual  auditory  olfactory  tactile  NOT Mouthpiece Eh onte lang teeth ng one year sensory experience old eh  Epileptic cry  Give pillows  support for the head (For banging of  Fall head during seizure activity)  Loss of consciousness for 3-5 minutes  Tonic-clonic contractions  Direct symmetrical extension of extremities  Shaking/convulsive activity  Post-ictal sleep (unresponsive sleep)  Petit Mal (Absence Seizure)  S/sx:  Blank stare  Decreased blinking of the eyes  Twitching of the mouth and loss of consciousness for 5-10 seconds 2. Partial Seizures  Jacksonian seizure (focal seizures) – characterized by tingling and jerky movements of index finger and thumb  spreads to shoulders  Psychomotor seizure (focal-motor seizures) – characterized by:  Automatism – stereotype, non-repetitive and non-purposive behavior  Clouding of consciousness – not in contact with reality  Mild hallucinating sensory experience 3. Status Epilepticus – continuous uninterrupted seizure activity that if left untreated may lead to hyperpyrexia  coma  death  Increased electrical activity in brain  increased metabolism  increased glucose and oxygen use, increased temperature  coma  death  DOC: Valium, Glucose C. DIAGNOSTICS 1. CT-SCAN – brain lesion d/t head trauma 2. EEG – hyperactivity of brain waves (all elevated)  Alpha, beta, delta, theta waves D. NURSING MANAGEMENT 1. Maintain patent airway and promote safety before seizure activity  Clear the site of sharps, harmful objects  Loosen clothing of the patient  Avoid use of restraints  fractures  Maintain side rails  Turn head to side to prevent aspiration  Tongue guard is between mouth and teeth to prevent biting of the tongue 2. Avoid precipitating stimulus  Bright/glaring lights  Noise 3. Administer medications as ordered  Phenytoin (Dilantin)  Gingival Hyperplasia  Use soft-bristled toothbrush  Ataxia  Nystagmus  HirsutismMS 10 Abejo
