In June 2013 the American College of Medical Toxicology (ACMT) released a Guidance Document on the Management Priorities in Salicylate Toxicity. Here are some key highlights:
- Continuous IV infusion of sodium bicarbonate is indicated even in the presence of mild alkalemia from the early respiratory alkalosis.
- Euvolemia is important.
- If intubation is required, administration of sodium bicarbonate by IV bolus at the time of intubation in a sufficient quantity to maintain a blood pH of 7.45-7.5 over the next 30 minutes is a reasonable management option during this critical juncture.
- Once airway control has been established, it is imperative that the increased minute ventilation and low PCO2 usually seen with salicylate intoxication are maintained.
- A salicylate concentration approaching 100 mg/dL warrants consideration of hemodialysis in the acute toxicity setting (40 mg/dL for chronic toxicity). Consult nephrology well before these threshold levels.
