Abstract

Introduction: Cardiovascular collapse due to large ingestions of isopropanol is rare. We report a case of a pediatric patient who had severe CNS and respiratory depression and cardiovascular collapse and was not hemodynamically stable enough to undergo hemodialysis. Case report: A 14-year-old 50 kg male was initially reported to have ingested an unknown amount of HEET® gas line antifreeze about 1 h prior to emergency department (ED) arrival. Despite severe CNS and respiratory depression and cardiovascular collapse, the patient was not initially acidotic. The patient did have an elevated osmolar gap. Approximately 6 h post-ingestion relatives updated the history to reflect that the product was in fact called ISO-HEET® which contains 99% isopropanol. Based on these concerns, a serum isopropanol and acetone levels were obtained that resulted at 475 and 75 mg/dL, respectively. Nephrology was consulted and it was decided to start the patient on sustained low-efficiency dialysis (SLED) which commenced 11 h post-ingestion. Serum and ultrafiltrate concentrations for isopropanol and acetone decreased to normal range over the course of SLED therapy. Discussion: SLED was instituted in this patient primarily for the treatment of elevated serum lactate, isopropanol, and acetone concentrations. The patient’s systemic clearance was calculated as 26.9 mL/min. During SLED therapy, the patient was able to clear isopropanol and acetone at 41.21 mL/min and 29.74 mL/min, respectively. SLED therapy is a viable treatment option when a patient is hemodynamically unstable and hemodialysis is not an option.
