Convulsions
Such convulsions or cramps are called uncontrolled tonic or clonic spasms of the muscles that unlike fibrillation (a muscle contraction wihtnout a locomotor effect) or twitching (a contraction of one muscle fibre) almost make the implementation of any voluntary activity impossible. Although they may be a completely benign phenomenon (typically cramps on the dorsal side of the thigh during sports or kneeling), they are often a side effect of serious illnesses (encephalitis, epilepsy, intoxitation, hypoglycemia). Whole-body convulsions are usually associated with a profound disorder of consciousness .
Dividing by clinical picture[edit | edit source]
For clinical purposes, convulsions are most often divided into:
- Clonic (short-lasting, recurrent twitches)
- Tonic (longer lasting muscle contractions)
- Tonic-clonic (combination of the the two, typical of grand mal seizures)
Division according to the causes[edit | edit source]
Simple aid for use on the patient - A dozen causes of unconsciousness
- Metabolic (hypoglycemia)
- Neurological (typically epilepsie)
- Intracranial expansion processes
- Febrilia (febrile convulsion occur mainly in children under 2-3 years of age)
- Affective respiratory attacks (in young children due to intense emotions - crying, laughing, when convulsions are provoked by temporary apnea)
- Syncope (in this case it is more of a rarity - so-called convulsive syncope with short-lasting convulsion)
- Deficiency of vitamins or minerals (sodium, potassium, magnesium) or, conversely, their excess
- Tetanic convulsions
- Endocrinopathy (hyperthyroidism)
- Eclampsia
- Intoxication – typically central psychostimulants (derivatives of excitatory amines)
- Withdrawal syndrome (Delirium tremens, withdrawal from benzodiazepines or barbiturates)
- Psychiatric
- as a result of psychiatric illnesses without primary neurological causes
- in neurodegenitary diseases
- somatoform (psychosomatic) disorders - pseudo-convulsions
- iantrogen-induced prolonged major seizures (GTCS) in electroconvulsive therapy (case studies)
Treatment[edit | edit source]
It is always necessary to keep in mind that convulsions are a symptom, and it is therefore necessary to treat their cause, not the convulsions themselves. However, the truth is that mostly clonic spasms can cause complications during treatment (during additional examinations, cannula insertion, etc.). In justified cases, it is therefore necessary to suppress muscle contractions. Benzodiazepines v (eg diazepam) are typically used for this purpose , especially in the case of status epilepticus. Other antispasmodics or muscle relaxants are possible. It is necessary to proceed with caution in case of intoxication with CNS depressants (alcohol, benzodiazepines, opiates), or in case of withdrawal from benzodiazepines - in this case, for example, clomethiazole (Heminevrin) may be indicated.
Adult patients[edit | edit source]
In most adult patients, the cause of the epileptic seizure grand mal, which usually does not endanger life in itself. In such a case can be given diazepam or phenytoin i.v. Diazepam also serve in the convulsions of unknown origin
If hypoglycemia is suspected, we administer 0,2–0,5 g glucose/kg i.v.
In case of tetanic convulsions, we give 10 ml of 10% solution of calcium chloratum i.v., possibly even 10 mg of a 10% magnesium sulfate solution.
Children[edit | edit source]
In children these are usuallyfebrile convulsions , which can be alleviated by diazepam administrated rectally (i.v. application could cause that an already traumatized child would be even more upset). Antipyretics are a matter of couse.
If tetanic convulsions are suspected, we administer 5 ml of a 10% solition of calcium chloratum i.v. and 5 ml of a 10% solution of magnesium sulphate
It is important to keep in mind that the convulsions themselves can sometimes endanger the patient's life (aspiration of regurgitated gastric contents, convulsions-related falls associated with head injuries).
