Popis: Abstract Background Super-absorbent polymers (SAPs) possess the ability to absorb large amounts of water and are widely used in medical settings. Commonly used in vomit bags to contain fluids, reduce spillage, and enhance bedside hygiene, SAPs are generally regarded as safe and non-toxic. However, we report a tragic incident where the accidental ingestion of SAPs led to fatal asphyxiation, highlighting a critical safety concern. Case presentation A 76-year-old female suffering from advanced Alzheimer’s dementia was brought to the emergency department following a fall with cervical trauma. Following a complaint of nausea, she was given a vomit bag containing a sachet of approximately 9 g of SAP. Thirty minutes later, she was found deceased in the waiting area, with a grayish, half-hardened gel blocking her oropharynx and remnants of a chewed SAP sachet. Pathological analysis confirmed death by asphyxiation caused by the SAP expanding in her oropharynx upon contact with saliva. Conclusions This case emphasizes the potential dangers of SAPs when accidentally ingested and it is imperative that such products are kept out of reach of vulnerable populations. In cases of airway obstruction, there are no specific treatments available. Laryngoscopy may be impossible, necessitating the prompt consideration of an emergency tracheotomy. Experimental data suggest the use of an aerosol of warm alkaline hydrogen peroxide solution to dissolve these obstructive foreign bodies, but further studies are needed to validate its use in emergency situations.
