Epidemiology of acute childhood poisoning in pediatric emergencies in Western Mexico.

INTRODUCTION

The increase in the production of substances to enhance the quality of life, the biodiversity of the different ecosystems in Mexico, and the unique characteristics of pediatric patients, contribute to intoxications within this population.

METHOD: Analytical retrospective study of admissions to pediatric emergency care due to poisoning in < 16-year-old (2016 to 2020). Included variables were age, gender, type of toxic substance, exposure characteristics, and the season of the year. Frequencies, percentages, range, average and standard deviation were obteined. In the bivariate análisis, the Chi square test was used. A p-value < 0.05 was considered statistically significant.

RESULTS

Over 5 years, there were 459 cases, with a prevalence of 3.16%. No gender predominance was observed. The most common was caused by venomous animals (28.5%), followed by medication ingestion (27.6%). Only 5% of cases were suicide attempts, the rest were accidental (95%). Children up to 5 years old were more commonly by medication ingestion, hydrocarbons, or household products (p = 0.03, p = 0.0001), while the causes in older children were contact with venomous animals and ingestion of stimulants drugs (alcohol, amphetamines, cannabis, cocaine) (p = 0.0001, p = 0.006). Intoxication with quaternary ammonium herbicides was lethal in all cases.

CONCLUSIONS

Children under the age of 5 are more susceptible to intoxication from common household products. Older kids tend to be more frequently a combination of stimulants drugs.
