yellow oleander poisoning




Plant poisonings are especially common among South Asian countries like India and
Sri Lanka.  Yellow oleander (ThevetiaPeruviana), an ornamental tree common
throughout the tropics is the source of majority of plant poisonings in these
regions.  Ingestion of oleander seeds, which contains highly toxic glycosides
including thevetins A and B and neriifolin, hampers the cardiac muscle and
autonomic nervous system resulting in cardiac dysrthythmias, sinus and AV node block, bradycardia, vomiting diarrhoea, hyperkalemia etc
Treatment for yellowoleander poisoning includes resuscitation, antidotes, gastric decontamination,
activated charcoal, atropine, cardiac pacing and supportive care
Gastric decontamination is consistently used throughout South Asia as a means of
decontamination. The different methods of gastric decontamination include forced
emesis and gastric lavage. Activated charcoal works by adsorbing poison and in
reducing further absorption.Decontamination techniques for yellow oleander poisoning include forced emesis, gastric lavage and single or multiple doses of activated charcoal.
  
 

 Currently proposed treatment and their likely benefit:
Likely to be beneficial/
Recommended for treatment
Anti-digoxin FAB fragments
Multiple dose activated charcoal

Unlikely to be beneficial
Single dose activated charcoal

Unknown effectiveness/
Requiring further studies
Forced emesis
Gastric Lavage
Transvenous cardiac pacing
