The patient, a 45-year-old male chemical factory worker, was burned by monochloroacetic acid discharged from a ruptured pipe. The patient was merely flushed with water and did not leave the workplace immediately. As a result, he suffered local burn symptoms, which gradually worsened. Two and a half hours after the accident, he developed symptoms of systemic poisoning, such as lethargy and dyspnoea. After a thorough debridement of the wound surface and subsequent skin grafting combined with early glucocorticoid therapy and haemofiltration, a satisfactory result was achieved, and the patient eventually recovered. With the widespread use of monochloroacetic acid in China, incidents of poisoning with this chemical are becoming increasingly common, with more than 100 cases reported in the past ten years in China alone., Radnik u kemijskoj tvornici u dobi od 45 godina zadobio je opekline izazvane monokloroctenom kiselinom koja je iscurila iz napukle cijevi. Ranu je samo isprao vodom i nije odmah napustio radno mjesto. Zbog toga je imao lokalizirane simptome opekline koji su se s vremenom pogoršavali. Dva i pol sata nakon nesreće pojavili su se simptomi sistemskog otrovanja poput letargije i zaduhe (dispneje). Cjelovito uklanjanje oštećenoga tkiva s površine i presađivanje kože u kombinaciji s ranim liječenjem glukokortikosteroidom i hemofiltracijom bilo je uspješno i bolesnik se naposljetku oporavio. S raširenom primjenom monokloroctene kiseline povećan je i broj otrovanja, koji je u posljednjih deset godina samo u Kini dosegnuo broj veći od 100 slučajeva.
