Burn injuries associated with the water tank of motorfarming tricycles in China.

Burns caused by hot coolant from the reservoir of motorfarming tricycles have not been reported previously. We performed retrospective studies of such cases in 126 patients with complete records in rural areas of China. The majority of victims were unmarried (59.5%), young (<40 years, >20, 55.6%), and male (male to female ratio 9:1). The burn accident occurred mostly during the busy seasons of spring and summer (66.7%). The mechanism of injury was usually the same. The drivers were trapped under the farming tricycle in a traffic accident and then hot coolant leaked from the mouth of the coolant, resulting in long contact with the hot fluid. The burn wounds were located mostly on the areas of the buttocks and lower extremities (especially on the thigh) (64.3%). The generally burned patients had moderate burn areas, about 20-50% total burn surface area (TBSA) of deep partial thickness or full thickness burn wound. For the purpose of decreasing the number of burns presenting, or at least making them less severe, the suggestions include: (1) the design of motorfarming tricycle should be changed; obviously separation of the coolant tank from the seat is the most important factor in reducing such burns. (2) Road conditions should be improved to reduce traffic accidents and loading regulations introduced. (3) Traffic control should be enhanced, especially in rural areas.
