Analysis of clinical characteristics and prognosis factors in children with acute gastrointestinal poisoning / 中国小儿急救医学

ABSTRACT

Objective To analyze the clinical characteristics in children with digestive tract poison-ing in emergency department and discuss the measures of prevention and treatment. Methods Four hundred and seventy-three cases with digestive tract poisoning who visited the emergency department of Zhengzhou Children′s Hospital were retrospectively analyzed from January 2015 to December 2017. The ages,toxic poi-soning causes,types,clinical features, laboratory examinations, hospitalization expenses and outcomes were analyzed. They were divided into drug poisoning and non-drug poisoning group to compare. Results There were 317 (67. 0%) cases aged 6 days to 3 years old,133 (28. 1%) cases aged 3 to 6 years old,23 cases (4. 9%) >6 years old. The incidence rate was similar in each season but slightly lower in winter. There were 462 (97. 7%) cases of accidental poisoning,of which 377 (79. 7%) cases were mistreated and 85 (18. 0%) cases were mistakenly fed by parents,other 11 (2. 3%) cases were non-accidental poisoning. Three hundreds and thirty-six (71. 0%) cases were drug poisoning,and 137 (29. 0%) cases were non-drug poisoning. Drug poisonings were higher in urban children than in rural children, the difference was statistically significant (χ2 ＝7. 037,P＝0. 008). The percentage of digestive symptoms and blood system symptoms in non-drug poi-soning group were higher than those in drug poisoning group,and the differences were statistically significant (54. 0% vs. 8. 3%,χ2 ＝120. 067,P<0. 001;7. 3% vs. 3. 0%,χ2 ＝4. 491,P ＝0. 034). The percentage of cardiovascular system symptoms and respiratory symptoms in the non-drug poisoning group were lower than that in the drug poisoning group,and the differences were statistically significant (1. 5% vs. 14. 9%, χ2 ＝17. 915,P<0. 001;2. 9% vs. 11. 0%,χ2 ＝8. 050,P＝0. 005). Except for liver function and myocardial en-zyme,the percentage of abnormal laboratory indicators(white blood cells,platelets,blood glucose,lactic acid, electrolyte,coagulation) in non-drug poisoning group were higher than those in the drug poisoning group,and the differences were all statistically significant(all P<0. 05). The hospitalization cost of the non-drug poison-ing group was greater than that of the drug poisoning group,and the difference was statistically significant (Z＝ －12. 444,P<0. 001). Both in the drug-poisoning group and non-drug poisoning group,the cure or im-provement rate of the <6 h treating group were higher than that of the >6h treating group,and the difference was all statistically significant(all P<0. 05). Conclusion Children with acute gastrointestinal poisoning are mostly infants and preschoolers,mainly accidental poisoning,and often taken by mistake. Drug poisonings are mostly found in cities and non-drug poisonings in rural areas. Non-drug poisoning children have more serious damages and higher hospitalization costs than drug poisoning children. Early treatment after poisoning is an important factor to improve cure rate.
