Trends in poisoning in children: experience at a large referral teaching hospital.
BACKGROUND
Poisoning is a major problem in the paediatric population. The offending substances used vary from place to place. Information on poisoning trends in India is meagre and there is an impression among clinicians that there has been a change in the commonly used poisons over the years. This retrospective study aimed to determine the pattern of poisoning in children and to study the nationwide trend over the past five decades.


METHODS
Case records of children (age group: 1 month and above) admitted to the Department of Paediatrics, King George's Medical College, Lucknow, Uttar Pradesh in three alternate calendar years, i.e. 1989, 1991 and 1993 were screened. All children were grouped into three categories based on the poison: (i) bites and stings, (ii) medicinal compounds, and (iii) non-medicinal compounds. The Indian literature on poisoning in children was reviewed and decade-wise data from a total of 22 studies (including the present study) were used to determine the changing trend.


RESULTS
Childhood poisoning constituted 2.1% of the total paediatric admissions and 1.2% of total deaths. Non-medicinal compounds were the largest contributors (69.2%), of which kerosene alone was responsible for 47% of cases. Medicinal compounds, and bites and stings accounted for 21.6% and 9.2% of these cases, respectively. The case-fatality rate was 9.2%. Comparison of our data, after excluding bites and stings, with a previous study (1977-79) from our institution showed that kerosene poisoning continues to be responsible for a substantial part of the morbidity (51.8% v. 31.5%). Also, poisoning due to insecticides and pesticides has increased (13.7% v. 2.1%) while that due to plant poisons (primarily dhatura) has reduced markedly (4.8% v. 19.2%).


CONCLUSIONS
Mortality due to poisoning in children has remained high over the last five decades (2.9%-4.7%). Kerosene has remained the single largest contributor to childhood poisoning (51.5% in the 1960s v. 52.8% in the 1990s).
