Rapid Read Ismael Kone suffered a freak injury during Canada's match against Qatar (Picture credit: AP) Canadian midfielder Ismael Koné suffered a freak injury during his team’s 6-0 win against Qatar on Friday and while he was being taken off the field on a stretcher, what drew attention was a green whistle that he was handed soon after and was seen inhaling from it. After a heavy collision with Qatari footballer Assim Madibo, medical staff rushed onto the field to treat Koné, who was in severe pain.
He was later diagnosed with a serious injury, confirming fractures to both the tibia and fibula. The severity of the incident left the crowd stunned, but the mood shifted to curiosity when medical staff were seen giving Koné a mysterious ‘green whistle’. The device permitted him to remain calm as he was stretchered off the field, even managing to acknowledge his teammates and the fans. But what is this unusual tool? As per Mundo América, the device is a ‘green whistle’, known as Penthrox. It’s a fast-acting inhaled pain reliever based on methoxyflurane, used in medical emergencies to manage moderate to severe pain, including injuries such as fractures. The medication is a fruity-smelling liquid that evaporates inside the device, permitting the patient to inhale it for pain relief under medical supervision.
Its effects are almost immediate and help reduce suffering, though it doesn’t act as a full anaesthetic or put the patient to sleep. This analgesic was once used as an anaesthetic in operating rooms but was later withdrawn because of the availability of safer alternatives at high doses. But as seen at this FIFA World Cup, it has resurfaced for use in non-hospital settings. A well-established practice in nations like the UK and Australia, it has become a valuable tool for managing on-field medical emergencies, helping footballers like Koné remain calm despite serious injuries that could rule them out for multiple months.
