Anion gap-opening metabolic acidosis and urinary findings in the early diagnosis of ethylene glycol poisoning: A case report.

Causative agent identification is important in the treatment of poisoning. We report the case of a patient who presented with an altered level of consciousness after drinking a fluorescent pink liquid. Upon measuring the anion gap and urinary calcium oxalate level, the patient was diagnosed with early ethylene glycol poisoning.

Neurological outcomes associated with prehospital advanced airway management in patients with out-of-hospital cardiac arrest due to foreign body airway obstruction.

Objectives: Several studies have examined the association between advanced airway management (AAM) and survival for arrest that is non-shockable, noncardiac in origin, or due to suffocation; however, the efficacy of prehospital AAM compared with no AAM following foreign body removal by emergency medical services (EMS) has not been examined. We aimed to compare neurological outcomes in patients after out-of-hospital cardiac arrest (OHCA) due to foreign body airway obstruction (FBAO) managed with and without AAM after foreign body removal.

Methods: This retrospective observational cohort study used all emergency transportation data of Japan and the All-Japan Utstein Registry.
