What are potential complications of using the King LT/IGEL?

The correct choice identifies sore throat as a potential complication of using the King LT/IGEL. This is a common issue associated with the placement of supraglottic airway devices like the King LT and IGEL. The device’s insertion can irritate the oropharynx and surrounding tissues, leading to temporary discomfort and soreness in the throat following the procedure.

When using airway devices, it's important to monitor for signs of irritation or trauma to the upper airway, which can manifest as a sore throat after intubation. Such complications can be common and generally resolve on their own, but they highlight the need for practitioners to consider patient comfort and follow up on any discomfort post-procedure.

The other complications listed are less commonly associated with the use of the King LT/IGEL. Hypotension, rash, and bradycardia can arise from various medical interventions or patient conditions, but they are not primarily linked to the insertion or use of the King LT/IGEL as specific complications in the same way sore throat is.
