A Calgary family is suing Concordia Hospital, Shared Health, and the Winnipeg Regional Health Authority, alleging that a massive overdose of the sedative propofol administered on March 25, 2024, resulted in severe and permanent injuries to their 23-year-old son, Zachary Hoogerdyk. Hoogerdyk, who was visiting Winnipeg for business and family, sought treatment at Concordia Hospital's Urgent Care for flu-like symptoms and difficulty breathing, and was diagnosed with hypoxia and influenza B. Despite being in good health prior, medical staff intubated him and administered propofol, allegedly in a dosage 12 to 60 times the safe range, with nearly an entire 1,000 mg bottle injected within 23 minutes. This overdose led to cardiac arrest, oxygen deprivation, a permanent anoxic brain injury, and the amputation of his right hand and both legs below the knee, leaving him with profound cognitive disability and requiring lifelong care.
