The National Poison Management and Control Center (NPMCC) was formed by merging the NPCIS and PGH Poison Control and Information Unit in January 2005.
The development of toxicology in the Philippines began in 1975 at the Philippine General Hospital (PGH) due to rising poisoning cases from pesticides.
From 1984 to 1989, PGH recorded an average of 190 poisoning cases per year, with the 1987 Department of Health statistics showing 279 cases at an incidence of 0.5 per 100,000 population.
Underreporting and misdiagnosis hindered comprehensive data collection on poisoning incidents.
In 1991, the Poisons Control and Information Service Network (PCISN) was established with support from the International Development Research Centre (IDRC) and GTZ to improve poison management.
The NPCIS was recognized as a focal point for a nationwide network managing poisoning cases and increasing public awareness of chemical hazards.

Trends in Poisoning Cases

Common toxicants managed at NPMCC include alcohol, kerosene, methamphetamine, sodium hypochlorite, and various pesticides.
Alcohol remains among the top five toxicants, influenced by aggressive marketing and social norms.
The prevalence of poisoning from methamphetamine has decreased, while newer stimulants like MDMA have seen a rise.
Two high-risk groups for poisoning incidents are young adults aged 20-35 and children under 6 years, primarily due to accessibility and curiosity.

Poisoning Case Statistics

Approximately 35% of cases handled by NPMCC involve accidental poisoning in children, with many incidents arising from unlabelled household chemicals.
Non-accidental poisoning, including suicide attempts, constitutes 60% of cases, with socio-relational conflicts as common triggers.
Historical data from the 1980s indicate that mortality rates for poisoning range from 2% to 9%, with significantly higher rates in males.

Strategies for Poison Management

The NPMCC focuses on training healthcare workers in poison recognition and management, along with creating public information campaigns.
Health advisories are released during surges in specific poisoning incidents, highlighting the center's role in chemical safety and community awareness.
Partnerships and networking among health professionals and policymakers are essential for effective poison prevention and control.

Definitions

Toxicity: Ability of a substance to cause biological injury.
Risk: Likelihood of injury occurring in specific situations.
Exposure: Contact with a chemical, potentially entering the body.
Poison: Agents that harm biological systems or cause death.
Accidental Poisoning: Non-intentional exposure to harmful substances.
Substance Abuse and Dependence: Patterns of drug use leading to impairment or distress, defined by specific DSM-IV-TR criteria.

Management of Poisoning

Key approaches include emergency stabilization, clinical evaluation, minimizing poison absorption, enhancing elimination, administering antidotes, and supportive therapy.
Emergency Stabilization focuses on maintaining airway, breathing, and circulation (the ABCs of life support) tailored to poison exposure severity.
Assess airway patency and address potential obstructions by positioning the patient correctly and performing necessary interventions for compromised airways.

Oxygenation and Mechanical Ventilation

Inadequate oxygen delivery may stem from ventilatory failure, hypoxia, or bronchospasm.
Assess ventilation accurately by checking arterial blood gases (ABGs).
Oxygen should be administered if clinical signs of poor oxygenation appear or if pO2 is under 80 mmHg.
Delivery methods include nasal cannula, face mask, or mechanical ventilator depending on equipment availability and required FiO2.
Bronchospasm requires evaluation for bronchodilator administration.

Common Toxicants Causing Hypoxia

Alcohol
Opiates
Quinine
Carbon monoxide
Organophosphates

Oxygen Delivery Modes and FiO2 Levels

Nasal cannula provides approximately 44% FiO2.
Plastic mask supplies about 60% FiO2.
Rebreathing mask delivers between 60 to 80% FiO2.
Mechanical ventilator can offer 100% FiO2.

Contraindications for Oxygen

Initial management of watusi poisoning requires caution; oxygen may cause explosions due to flammability.
In paraquat poisoning, oxygen increases pulmonary fibrosis risk.

Maintaining Adequate Circulation

Establish intravenous (IV) access and begin infusion of appropriate fluids.
Hypotension can be treated with IV fluids when systolic blood pressure is low.

Digitalis Toxicity

Digoxin toxicity can arise from chronic drug intake without dosage adjustments under certain conditions.
Acute toxicity is influenced by thyroid dysfunction, renal issues, electrolyte imbalances, and myocardial disease.

Drug Interactions Increasing Digoxin Levels

Amiodarone, macrolide antibiotics, carvedilol, quinidine, diltiazem, spironolactone, indomethacin, and verapamil enhance toxicity.

Metabolic Imbalances Affecting Toxicity

Hypokalemia, hypernatremia, hyperkalemia, alkalosis, hypomagnesemia, and hypoxemia can increase the risk of digoxin toxicity.

Management of Digitalis Poisoning

Supportive treatment is generally effective.
Charcoal and cholestyramine can aid in drug removal.
Cardioversion is not advisable due to arrhythmia risks.

Symptoms of Digitalis Toxicity

Acute: GI disturbances, cardiovascular symptoms, CNS effects like convulsions or visual disturbances (yellow halos).
Chronic: weakness, similar CNS manifestations, bradyarrhythmias, and atrial fibrillation.

Toxicologic Examination

Monitor serum digoxin levels 6 hours after ingestion and monitor ECG for abnormalities.
Serum chemistry, CBC, and electrolytes are essential in assessing the extent of toxicity.

Supportive Measures for Life Support

Maintain airway, breathing, and circulation (ABCs).
Initiate IV fluids, monitor cardiac status, and consider nasogastric tube insertion.
Gastric lavage may be necessary in acute poisoning cases to reduce toxin absorption.

Seizure Management

Diazepam (for adults) and lorazepam (for pediatric patients) may be given for seizure control.

Deferoxamine for Iron Toxicity

Indicated when serum iron levels exceed 500 mcg/dL, indicate clinical symptoms, or present on radiographs.
Treatment cessation is appropriate when serum iron drops below 150 mcg/dL and signs of poisoning are resolved.

Clinical Signs of Iron Toxicity

Early symptoms include severe hemorrhagic gastritis, diarrhea, and lethargy.
Delayed onset may lead to serious consequences such as gastrointestinal perforation, liver failure, and metabolic acidosis.

Laboratory Tests for Iron Poisoning

Total serum iron tests must be conducted 3 to 5 hours post-ingestion.
Monitor for signs of iron overload with regular blood tests to adjust treatment as necessary.
