Different anatomical sites of the foreign body injury with 2999 children during 2012–2016

PURPOSE: This study aimed to analyze the clinical characteristic of different foreign body injuries in children and offer the preventions. METHODS: A retrospective study and the demographic information, injury causes, foreign body injury types and other clinical factors were recorded and analyzed. RESULTS: Of the 2999 patients, 1877 (62.6%) were boys and 1122 (37.4%) were girls. The majority (72.8%, n = 2184) of the injuries were found in 1–3 years old children. The most common anatomical site was the respiratory tract (73.4%, n = 2201) followed by the digestive tract (18.6%, n = 558), the genitourinary tract (1.93%, n = 58) and other sites (6.07%, n = 182). There were 60.4% of the in-patients from rural areas and 53.2% of the patients without medical insurance, the rate of cost by medical insurance increased with age. The medians of length of hospital stay and hospitalization cost were four days and 4767.3 CNY respectively. Most of the patients had surgical treatment (90.6%, n = 2717) and 64.9% of them had the complications (n = 1946). The cure rates of the all foreign body injuries types were above 90%, especially in genitourinary tract (98.3%). CONCLUSION: Different types of the foreign body injuries had dissimilar clinical characteristics. The effective prevention and control measures should be taken according to the variety of high-risk population, incidence season and foreign body injury types.
