A former hospital anaesthetic technician could have put the lives of three vulnerable patients at risk, by stealing their painkillers for himself, just before or during their operations. Evan Leslie Kajewski, 40, who substituted the drug fentanyl with saline solution while working at the Mater Hospital last year, has been jailed for two months. “His actions in replacing fentanyl with saline solution was when patients were at their most vulnerable,” magistrate Judith Daley said. Innocent people were put at risk, prosecutor Maria Vassilakos told the court. Kajewski pleaded guilty to fraud, stealing as a servant while working at Brisbane’s Mater Hospital, unlawful possession of the opiate drug fentanyl and possession of drug utensils.
