The review methods included the analysis of scientif i c publications located in databases such as PubMed and scientif i c journals, including meta-analyses, randomized trials and systematic reviews regarding the scope of the problem of choking in children, excluding case reports. Choking is most often caused by the aspiration of foreign objects such as small toys, food (e.g. grapes, nuts, pieces of meat) and other small objects that children often put into their mouths out of curiosity. Children aged 1 to 4 are particularly vulnerable as they have a natural tendency to explore their surroundings using their mouths. Symptoms of choking may include sudden difficulty breathing, intense coughing, wheezing, cyanosis and loss of consciousness. Quick recognition of symptoms is crucial to prevent serious consequences, such as cerebral hypoxia or cardiac arrest. In diagnostics, it is also important to take a thorough history and use imaging tests, such as X-ray or bronchoscopy, to locate and remove the foreign body.
