In nature, there are many beautiful things that appear to be harmless to humans and animals, but actually carry sharp spikes and even deadly toxins. Today we are going to discuss a very beautiful plant called foxglove. Many flower lovers wonder whether it is poisonous. Let's go and see.
Is foxglove poisonous?
The whole plant of foxglove is poisonous. The toxic substances are strong and it is an important cardiotonic. It can excite the myocardium, enhance myocardial contractility, improve blood circulation, or directly inhibit the intracardiac conduction system. However, the therapeutic dose of this type of drug is quite close to the toxic dose, causing anorexia, salivation, abdominal pain and diarrhea, and occasionally hemorrhagic gastritis and retrosternal pain. More common in adults. Another early symptom is oliguria. Heart symptoms are the presence or occurrence of various types of arrhythmias, such as tachycardia or bradycardia, and changes in heart rhythm, such as premature beats, synapses, paroxysmal tachycardia, ventricular fibrillation, and various levels of atrial fibrillation. ventricular conduction resistance. Ventricular fibrillation and ventricular asystole are the most serious arrhythmias and can be directly life-threatening. Finally, convulsions, collapse, coma, etc. occur.
Treatment of digitalis poisoning:
1. If toxic reactions occur, digitalis should be stopped immediately, potassium salt supplemented, potassium-depleting diuretics stopped, and arrhythmia corrected.
2. Patients with mild poisoning should stop using this product and diuretic treatment. If you have hypokalemia and your kidney function is good, potassium salts can be given.
3. Arrhythmia can be used:
Intravenous infusion of potassium chloride is often effective in eliminating ectopic heart rhythms.
Phenytoin can compete with cardiac glycosides for sodium-potassium adenosine triphosphatase and has a detoxifying effect. For adults, slowly inject 20 ml of 100-200 water for injection intravenously. If the situation is not urgent, you can also take it orally, 0.1 each time, 3-4 times a day.
Lidocaine can effectively eliminate ventricular arrhythmias. For adults, add 50-100% to intravenous glucose injection and repeat if necessary.
Atropine can be used in patients with bradyarrhythmia. Adults use 0.5-2 subcutaneous or intravenous injections.
When bradycardia or complete atrioventricular block suggests AS syndrome, a temporary pacemaker can be placed. Isoproterenol can increase slow heart rate.
Summary
: However, flower lovers, don’t worry too much. This kind of poisoning can only occur when a person eats it, and it will not be poisonous by ordinary contact. So although foxgloves are known to be poisonous, it is rare to hear of foxglove poisoning.
