Bleach (Sodium Hypochlorite) Ingestion in the Emergency Department
Bleach ingestion is managed as a corrosive-caustic exposure with immediate stabilization, symptom-directed evaluation, and avoidance of gastrointestinal decontamination measures that can worsen caustic injury. [1,2] Supportive care is the mainstay because no specific antidote exists for hypochlorite poisoning. [1]
Initial Stabilization and Secondary Prevention
Immediate priorities include airway, breathing, and circulation assessment with treatment of hypoxemia or respiratory distress as needed. [2] Assessment should include evaluation for oral and oropharyngeal injury symptoms such as pain, drooling, dysphagia, stridor, and vomiting. [1] Rescuer/ED contamination risk should be assessed because clothing or skin soaked with industrial-strength hypochlorite can be corrosive to rescuers and may release harmful vapor; appropriate protective measures should be used. [1] Poison Control or a medical toxicologist should be contacted early for product-specific guidance. [1]
Diagnostic Evaluation in Suspected Corrosive Injury
Clinical evaluation should focus on severity of mouth and gastrointestinal tract injury symptoms and the presence of respiratory complaints given the risk of pulmonary complications from aspiration. [1] Because bleach ingestion can cause progressive symptoms, observation and reassessment for worsening chest or abdominal pain, dysphagia, wheezing, and dyspnea are required. [1]
Gastrointestinal Decontamination Avoidance
Emesis induction should be avoided. [2,3] Gastric lavage should be avoided. [2] Activated charcoal should be avoided after bleach ingestion. [2] Small-volume dilution with water or milk may be considered for comfort to reduce irritation, with the dilution amount kept small to reduce risk of vomiting. [2]
Supportive Treatment
No specific antidote exists for hypochlorite poisoning, so care is supportive. [1] Symptom-targeted management should include treatment for pain, nausea/vomiting, and complications such as respiratory injury from aspiration. [1,2] Inhalation co-exposure should be treated with removal from the exposure and supportive respiratory care as clinically indicated. [2]
Skin and Eye Exposure Management
If skin is contaminated, flushing with copious amounts of plain tepid water is recommended to reduce injury. [2] If eyes are exposed, irrigation with saline or Ringer’s lactate is recommended. [2]
Monitoring and Disposition
Serial monitoring is required because serious symptoms can require hospitalization and symptoms may worsen over several hours after serious exposure. [1] Patients with only minor irritation and no significant symptoms may be considered for discharge after a period of observation with return precautions for new or worsening symptoms. [1]
Indications for Higher Level of Care
Escalation to hospital care is indicated for significant symptoms such as difficulty swallowing, chest or abdominal pain, coughing or wheezing, and respiratory distress. [1] Hospitalization is indicated for serious symptoms due to the risk of pulmonary complications and progression of injury. [1,2]
Endoscopy and Surgical Consultation
Endoscopic evaluation and surgical consultation should be pursued when clinical features suggest significant corrosive injury severity or suspected complications such as perforation. [4] Chest and abdominal imaging is commonly used in caustic ingestion to detect free air when perforation is a concern. [4]
Key Toxicology Points to Guide Management
Hypochlorite ingestion can cause corrosive injury to the gastrointestinal tract with symptoms such as mouth or throat pain, dysphagia, stridor, drooling, and vomiting. [1] Aspiration can lead to pulmonary complications. [1]
Case Data Elements to Obtain in the ED
History should include timing of ingestion, identity and concentration of the product, and estimated amount ingested. [4]
References for Immediate ED Workflow
Poison Control should be used to refine management based on product concentration and clinical severity. [1,3]
