[Children's scalds from tearing of hot water bottle].

INTRODUCTION: Children scalded by the tearing of hot-water bottles presented a sudden and significa tive increase around 2000 in Chile. For this reason the Aid to Burned Children Corporation (COA-NIQUEM) publicized prevention concepts concerning the careful use of this device and raised a voice of alarm to authorities. Later, the National Normalization Institute introduced quality certification standards for hot water bottles sold in the country.

OBJECTIVES: Determine the impact of preventive measures and quality certification for hot water bottles in burns caused by tearing of the device on children.

PATIENTS AND METHOD: Review of 795 patients under 15 admitted with injuries caused by hot-water bottle rupture between 2000 and 2014 at COANIQUEM Santiago. The frecuency of burns by the ethiological agent is determined and the epidemiological profile are compared in the initial and final quinquenial period.

RESULTS: Between 2000-2004, an increase of 272.7% was recorded and then a decrease of 81.3 % was found between 2005-2014. Demographic characteristics, month of occurrence and need of some kind of surgery were similar in both periods. The number of locations and injuries diminished, and are concentrated in one burn (77.8%). In the first period the main anatomical region affected was lower limbs and in the second period abdominal and pelvis are also frequent.

CONCLUSIONS: An important decrease of burns by hot-water bottle rupture with significant changes in their epidemiological characteristic is verified. This coincides with preventive measures and manufacturing standards regulations and quality control.
