This case report described the use of the i-gel for the management of ventilation in an ICU patient. A 49-year-old woman was hospitalized in ICU due to fever and respiratory distress. Three intubations using a bougie failed, but the airways were subsequently secured with an i-gel (size 3) at the first attempt. No issues were seen in mechanical ventilation using the i-gel for 48 hours in pressure-controlled ventilation. Thus, the i-gel can be used in difficult intubation scenarios, allowing mechanical ventilation up to 48 hours.
