50
Q

Poison Management

A
  • Decrease absorption
  • Enhance elimination
  • Implement toxin-specific interventions per poison control center
51
Q

Poisoning Management: Decreasing Absorption

A

Gastric Lavage which is performed within one hour of ingestion of moist poisons

52
Q

What happens during a gastric lavage?

A
  • Intubated before lavage if altered LOC or diminished gag reflex
  • Involves oral insertion of a large-diabetes (36F-42F) gastric tube for irrigation of copious amounts of saline.

  • Coingested sharp objects
  • Ingested nontoxic substances
54
Q

Problems associated with gastric lavage include

- Aspiration

55
Q

Activated Charcoal

A
  • Most effective intervention for management of poisonings.

  • Administered orally or via gastric tube within 1 hour of poison ingestion.
56
Q

What are contraindications of activated charcoal?

A
  • Diminished bowel sounds
  • Paralytic ileus

Do not give immediately before, with, or shortly after charcoal.

58
Q

Poisonings: Dermal cleansing/eye irrigation

A
  • Removal of toxins from skin and eyes using copious amounts of water or saline.
  • Most toxins, with the exception of mustard gas, can be safely removed with water and saline (this is because water mixes with mustard gas and releases chlorine gas)
  • Brush dry substances front he skin and clothing before using water. (Do not remove powdered lime with water, should be brushed off)
59
Q

During dermal cleansing/eye irrigation,

A
  • Wear PPE

- Decontamination takes priority over all interventions except BLS measures

60
Q

Poisoning Management: Enhance Elimination

A
  • Cathartics (sorbitol)

- Whole bowel irrigation *high risk of electrolyte imbalance

61
Q

Cathartics

A

Give with first dose of charcoal to stimulate intestinal motility/increase elimination

62
Q

Poisoning Management: Hemodialysis/hemoperfusion

A
  • Reserved for severe acidosis
    -Urine alkalinization (Phenobarbital and salicylate poisoning)
  • Chelating agents (↑ Amphetamine and quinidine excretion)
  • Antidotes (Very few available)

*check notes
