ReviewValproic acid poisoning: an evidence-based consensus guideline for out-of-hospital management.
A review of US poison center data for 2004 showed over 9000 ingestions of valproic acid. A guideline that determines the conditions for emergency department referral and prehospital care could potentially optimize patient outcome, avoid unnecessary emergency department visits, reduce health care costs, and reduce life disruption for patients and caregivers. An evidence-based expert consensus process was used to create the guideline. ⋯ Prehospital activated charcoal administration, if available, should only be carried out by health professionals and only if no contraindications are present. Poison centers should follow local protocols and experience with its use. Do not delay transportation in order to administer activated charcoal (Grades D). 9) In patients who have ingested valproic acid and who are comatose, naloxone can be considered for prehospital administration in the doses used for treatment of opioid overdose, particularly if the patient has respiratory depression (Grade C). 10) A benzodiazepine can be administered by EMS personnel if convulsions are present and if authorized by EMS medical direction, expressed by written treatment protocol or policy, or if there is direct medical oversight (Grade C).
