Ethylene Glycol Toxicity
Toxic dose requiring medical trematment is 0.1ml/kg body weight or 4 ml for 20 Kg child
Lethal dose in humans is 1.4ml/kg or 56 ml for a 20 kg child
Ethylene glycol does not evaporate so inhalational exposure is unlikelyEthylene glycol is not absorbed through skin so dermal exposure is also uncommon

NPIS annual Report 2010-2011
➲ Prospective audit➲ Toxic alcohol and glycol cases reported through telephone
enquiries to the NPIS in 2010➲ Aim: 1. To provide information on the frequency, current
management and outcomes of systemic toxic alcohol poisoning.2. To provide information on which to base the planning of clinical services for this type of poisoning, including appropriate availability of assays and antidotes.

Results
➲ 488 individual exposures➲ 250 in non hospital sourced
➲ 89 (18%) cases less than 5 years old➲ 238 in hospital sources➲ 182 potentially systemic exposures
➲ 99 (20%) reqiured treartment with antidotes➲ 33 haemodialysis, heamofiltration➲ At least 2 severe cases each week nationally
➲ Main difficulty in management is unavailability of lab assayand inadequate stock of antidote

Summary
➲ Glycol and Toxic alcohol toxicity though less common in UK is a significant differntial diagnosis to consider especially in cases of disproportionate metabolic acidosis
➲ It is important to plan and consider how we can treat such a case in our unit, especially when most of us donot stock any of the antidotes
