Ep 22 - Button Battery ingestion in children

The Danger of Button Batteries: Essential Information for Emergency Physicians Introduction Hello and welcome to the St Emlyn's blog. I'm Simon Carley, and alongside me is Natalie May. This post addresses a frequent and potentially serious issue in emergency departments: the ingestion of button batteries. With Halloween and Christmas approaching, these small but hazardous objects become more prevalent in households with small children. Here, we provide critical insights for emergency physicians on identifying, managing, and preventing complications related to button battery ingestion. Understanding Button Battery Ingestion Button batteries, or disc batteries, are small, round batteries found in devices like watches, musical badges, and holiday decorations. Their size and shiny appearance make them attractive to children, who may ingest them or insert them into their noses or ears. While they appear harmless, button batteries can cause significant harm if they become lodged in mucosal surfaces. The Risks of Button Battery Ingestion When a button battery becomes wedged against a mucosal surface, it generates a small electrical current. This current can cause chemical burns and tissue damage within as little as two hours. If not promptly removed, the battery can lead to severe complications, including death. Common Scenarios and Symptoms Children often ingest various objects, but button batteries pose a unique risk due to their electrical properties. Here are common scenarios and symptoms to watch for: Ingestion: Symptoms range from mild (drooling, difficulty swallowing) to severe (vomiting, abdominal pain, gastrointestinal bleeding). Nasal Insertion: Batteries in the nose can cause nasal discharge, pain, and significant tissue damage if unnoticed. Ear Insertion: Batteries in the ear can lead to pain, discharge, and hearing loss if not promptly addressed. Radiological Identification Button batteries are radiopaque, making them visible on X-rays. They can be distinguished from coins by their characteristic double shoulder appearance. This feature is crucial for accurate diagnosis and timely intervention. Management Strategies Immediate Steps for Suspected Ingestion High Index of Suspicion: Be vigilant for signs of button battery ingestion, especially if parents report missing batteries from devices. Radiological Examination: Perform an X-ray to locate the battery and determine its position. Removal from Ears and Noses ENT Referral: Button batteries in the nose or ears should be removed promptly by an ear, nose, and throat specialist. These areas are less moist than the esophagus but can still suffer chemical burns and tissue damage. Esophageal Ingestion Surgical Emergency: Batteries lodged in the esophagus must be removed immediately. This task is typically handled by general surgeons or gastroenterologists. Delaying removal can lead to severe complications, including perforation, erosion into blood vessels, and catastrophic bleeding. Post-Removal Care and Follow-Up Even after successful removal, children must be monitored for complications. Discharge instructions should include warning signs such as gastrointestinal bleeding, severe abdominal pain, vomiting, respiratory distress, and refusal to eat. Follow-up appointments and possibly additional X-rays are essential to ensure no further damage has occurred. Prevention Tips for Parents Educating parents about the dangers of button batteries is crucial. Here are some tips to share with them: Secure Storage: Keep button batteries out of reach of children. Device Safety: Ensure battery compartments in devices are secure and childproof. Immediate Action: If a battery is missing and a child shows symptoms of ingestion, seek medical attention immediately. Case Studies and Real-Life Examples Case 1: Nasal Insertion A child was brought to the emergency department with a suspected nasal insertion of a button battery. Despite a thorough examination, no battery was visible. Howev
