MANAGEMENT OF ACUTE CHILDHOOD POISONINGS IN PEDIATRIC EMERGENCY DEPARTMENTS: IMPACT OF A SOCIETY’S GUIDELINES Introduction: In a multicenter study conducted in 2001-2002 in 17 Spanish Pediatric Emergency Departments (PED) integrated in the Spanish Society of Pediatric Emergency Medicine (SEUP), great management variability was detected. In this way, decontamination procedures were not always adequated. This fact conducted SEUP to elaborate protocols and guidelines of management of acute childhood poisoning in PEDs. The aim of the study was to analyse the impact of the guidelines in the management of acute childhood poisonings in Spanish PEDs Methods: We underwent a comparative study including all the children admitted in different Spanish PEDs with an acute poisoning in two periods of time 2001 Jan – 2002 Dec: group A (2157 children) 2007 Oct – 2008 Apr: group B (612 children) Physicians completed a questionnaire with each patient including age and sex; attending hospital; circumstances associated with the poisoning; toxic compound type; time between exposure and arrival to the emergency department; symptoms and signs; type of medical assistance before admittance to the emergency room; treatment at the emergency department (basic life support, gastrointestinal decontamination, antidote, or symptomatic therapy); laboratory tests and other investigations including toxicological analysis; and patient’s final outcome. Results: Of the 2157 children included in group A, 1116 received any treatment in the PED (51.7% vs 273 of patients included in group B, 44.8%, p=0.002), mostly decontamination procedures (733 in group A, 33.9%, vs 170 in group B, 27.8%, p=0.004). Among patients in which any decontamination procedure was practiced, 594 (80.4%) in group A received activated charcoal (vs 159 in group B, 93.5%, p=0.0001), 209 gastric lavage (28.5% vs 46, 27.1%, in group B, p>0.05) and 164 (22.3%) ipecac syrup (vs 3, 1.8%, in group B, p<0.00001) Conclusions: development and distribution of guidelines supported by the Spanish Society of Pediatric Emergency Medicine has been associated with a significant improvement of management of acute childhood poisonings in Spanish PEDs.
