• Dehydrator as evidence of mushroom preparation

Medical Treatment and Patient Outcomes

• Associate Professor Steven Warlo oversaw the care of four critically ill patients suffering from amatoxin poisoning at Austin Hospital.
• The patients, Don and Gail Patterson, Heather and Ian Wilkinson, were on mechanical ventilators, dialysis, and complex infusions to support their breathing, blood purification, and circulation.
• Specific therapies were administered to protect the liver from further injury.
• Don, Gail, and Heather Patterson died from the poisoning.
• Ian Wilkinson survived after a prolonged period of stabilization, including concerns about intestinal injury.
