Poisoning emergencies in Nigeria present unique clinical challenges shaped by both local industrial practices and traditional home management. Midwives and nurses must recognize the most frequent agents causing accidental and intentional toxicity in our environment.
Poisons enter the body through four primary routes: ingestion, inhalation, absorption through the skin or mucous membranes, and injection. Identifying the exact route dictates how quickly the toxin spreads and guides the initial emergency response.
Before rendering any form of assistance, the attending midwife or nurse must evaluate the environment to prevent becoming a secondary victim. Scene safety is paramount.
Never rush blindly into a poorly ventilated room filled with chemical fumes, an enclosed space smelling of insecticides, or an area with aggressive bystanders. Always don appropriate personal protective equipment, such as gloves and masks, before touching a contaminated patient.
Once safety is established, perform a rapid primary survey using the Airway, Breathing, Circulation, Disability, and Exposure (ABCDE) approach. Check if the patient is responsive, maintain a patent airway, and assess for adequate chest rise. If the patient is unconscious but breathing, place them in the recovery position to prevent aspiration of vomitus. Gather quick history clues from relatives or bystanders regarding what was swallowed, spilled, or inhaled, keeping any suspected containers or vomitus samples for laboratory identification.
Removing the poison from the patient's body prevents further absorption. The method depends entirely on where the toxin contacted the body.
For skin contamination, immediately remove all contaminated clothing. Wash the affected skin thoroughly with copious amounts of running water and mild soap for at least fifteen to twenty minutes. Avoid scrubbing aggressively, as this can break the skin barrier and increase toxin absorption.
For eye splashes, flush the eyes continuously with clean, lukewarm water or normal saline from the inner corner outward for at least fifteen minutes. Remove contact lenses if present.
For ingested poisons, the old practice of routine vomiting induction using salt water or palm oil is dangerous and strongly discouraged, especially for corrosive substances or petroleum products, because vomiting causes secondary burns to the esophagus and aspiration pneumonia. Gastric lavage is rarely performed now and is only considered if the patient presents within one hour of ingesting a life-threatening amount of a toxin.
A toxicdrome is a constellation of signs and symptoms that suggest a specific class of poison. Recognizing these clusters helps nurses make quick decisions when the exact substance is unknown.
While stopping further exposure and decontaminating the patient are vital, supportive nursing care saves lives during poisoning emergencies. Most poisoned patients recover completely with meticulous monitoring of vital signs, maintaining airway patency, correcting fluid and electrolyte imbalances, and managing seizures.
Specific antidotes exist for only a small percentage of poisons, but where available, they are life-saving:
Careful observation is required because patients can deteriorate suddenly, especially when long-acting toxins are involved.
Midwives and nurses hold a strategic position in Nigerian communities to prevent accidental poisonings before they happen. Clinical duties extend beyond hospital walls into antenatal clinics, immunisation posts, and community outreaches.
