How to manage children with various types of poisoning in children?
Managing poisoning in children
involves a combination of immediate interventions, specific treatments, and
ongoing supportive care. Here’s a comprehensive guide for managing children
with various types of poisoning:
General Principles
1.
Initial Assessment and
Stabilization
·
Airway, Breathing, Circulation
(ABCs): Ensure the airway is clear,
provide oxygen if needed, and maintain circulation with IV fluids if necessary.
·
Vital Signs: Monitor heart rate, respiratory rate, blood pressure, and
oxygen saturation.
2.
History and Identification
·
Obtain detailed information about
the substance involved, amount ingested, time of ingestion, and route of
exposure (oral, inhalation, dermal).
·
Identify the poison if possible,
using containers, labels, or input from caregivers.
3.
Decontamination
·
Gastrointestinal: Consider activated charcoal (1 g/kg, up to 50 g) if the
child is alert and the ingestion occurred within the past hour. Avoid if the
child has a compromised airway.
·
Dermal: Remove contaminated clothing and wash the skin thoroughly
with soap and water.
·
Ocular: Rinse the eyes with water or saline for at least 15
minutes.
4.
Symptomatic and Supportive Care
·
Seizures: Use benzodiazepines (e.g., diazepam, lorazepam) if
seizures occur.
·
Hypotension: Administer IV fluids and vasopressors if needed.
·
Arrhythmias: Monitor and treat cardiac arrhythmias according to
standard protocols.
Specific Poison Management
1.
Acetaminophen (Paracetamol)
Poisoning
·
Antidote: Administer N-acetylcysteine (NAC) as soon as possible. The
dosing regimen includes a loading dose followed by maintenance doses over 20
hours (IV) or 72 hours (oral).
·
Monitoring: Check liver function tests, acetaminophen levels, and
coagulation profile.
2.
Salicylate (Aspirin) Poisoning
·
Decontamination: Consider activated charcoal if within the appropriate time
frame.
·
Alkalinization: Administer sodium bicarbonate to alkalinize the urine and
enhance salicylate excretion.
·
Monitoring: Check salicylate levels, electrolytes, and arterial blood
gases.
3.
Iron Poisoning
·
Antidote: Administer deferoxamine if serum iron levels are
significantly elevated or if severe symptoms are present.
·
Monitoring: Monitor serum iron levels, liver function, and renal
function.
4.
Opioid Poisoning
·
Antidote: Administer naloxone. The initial dose is 0.1 mg/kg, which
can be repeated as needed.
·
Supportive Care: Provide respiratory support due to the risk of respiratory
depression.
5.
Organophosphate Poisoning
·
Antidotes: Administer atropine and pralidoxime (2-PAM).
·
Monitoring: Monitor cholinesterase levels, respiratory function, and
cardiovascular status.
6.
Benzodiazepine Poisoning
·
Antidote: Administer flumazenil with caution, considering the risk
of seizures.
·
Supportive Care: Monitor respiratory and cardiovascular status closely.
7.
Caustic Ingestion (Acids or
Alkalis)
·
Do Not Induce Vomiting or give activated charcoal.
·
Supportive Care: Provide pain management, IV fluids, and monitor for signs
of esophageal or gastric perforation.
8.
Carbon Monoxide Poisoning
·
Oxygen Therapy: Administer 100% oxygen via a non-rebreather mask or
consider hyperbaric oxygen therapy in severe cases.
·
Monitoring: Check carboxyhemoglobin levels and monitor for
neurological symptoms.
9.
Anticholinergic Poisoning
·
Antidote: Administer physostigmine if severe symptoms are present
and under careful monitoring.
·
Supportive Care: Control agitation and seizures with benzodiazepines.
10.
Methanol/Ethylene Glycol
Poisoning
·
Antidotes: Administer fomepizole or ethanol.
·
Additional Treatment: Hemodialysis may be required in severe cases.
·
Monitoring: Monitor electrolytes, renal function, and acid-base
status.
Conclusion
Managing pediatric poisoning
requires a thorough and systematic approach, starting with stabilization and
identification, followed by appropriate decontamination, administration of
specific antidotes, and continuous supportive care. Always involve a poison
control center for guidance and ensure close monitoring of the child’s clinical
status throughout the treatment.
