seizure disorder
SEIZURE
Caused by transient, paroxymal and synchronous discharge
of groups of Neurons in the brain
Clinical manifestations depends on the location and number
of neurons involved, in the seizure discharge and its duration.
May be
1.Transient or
2.Permanent (Epilepsy)
Classification of Epileptic seizures
• Partial
• Generalized
• Unclassified
PARTIAL
-Simple partial seizures (consciousness not impaired)
- Complex partial seizures (consciousness impaired)
- Partial seizures evolving to generalized seizures (Tonic, clonic or tonic-clonic)
GENERALIZED SEIZURES
(Convulsive or non convulsive)
•Absence seizures
•Myoclonic seizures
•Clonic seizures
•Tonic seizures
•Clonic tonic seizures
•Atomic seizures.
DRUGS USED IN DIFFERENT DISORDERS
Partial Seizures
- Carbamazepine
- Phenyotin and
- valproate
Generalized seizures
- Carbamazepine
- Phenyotin
- Valproate
- Barbiturates
- Gabapentin or
- Lamotrigine
Generalized non seizures
- Ethosuximide (or)
- Valproate
SIDE EFFECTS
Depression of cerebral function with symptoms of sedation
- Diploma
- Persistent or fluctuation ataxia
Dyskinesias of the tongue, face and limbs
- Mild sensory neuropathy
- Altered peripheral nerve function
•Hepatic failure
• Pancreatitis
• Mild anaemia to aplastic anaemia
• Depress circulating platelets
• Skin rashes
• SLE
• Seroderma and
• Sjogrens syndrome
• Steven johnsons syndrome
STATUS EPILEPTICUS
Def : Continuous seizure activity or two or more seizures
occurring in sequence without recovery of consciousness between the seizures
PHARMACOLOGIC MANAGEMENT OF STATUS EPILEPTICUS
1.Lorazepam / Diazepam – 0.1 mg / kg I.V at 2 mg/ min
2.Phenytoin – 20mg / kg I.V at 50mg / min or fosphenytoin 20mg/kg IV at 150mg/min
3.Phenyotin or fosphenytoin additional 5-10 mg/kg
4.Phenobarbitol 20mg/kg I.V at 50-75 mg/min
5.Phenobarbitol – additional 5-10mg/kg
6.Anaesthesia with propofol or midazolam
OTHER AREAS OF TREATMENT
•Exclude hypoglycemia
•Tracheal intubation
•ABG
•Hyperthermic management
Management of Anaesthesia for seizure disorders
Consider impact of drugs on organ function
- Coagulation
- Response to anaesthetic drugs.
