Which of the following is NOT a side effect of the King LT/IGEL?

The correct answer identifies that infection is not commonly considered a direct side effect of the King LT/IGEL airway devices. While the use of these devices can lead to complications, and infections can occur due to any invasive procedure, infection is not a direct or immediate side effect associated specifically with the use of the King LT or IGEL.

In contrast, sore throat and dysphagia (difficulty swallowing) are well-documented side effects following the use of these supraglottic airway devices. These side effects often result from irritation or trauma to the throat area due to the insertion of the device.

Esophageal rupture is a rare but serious complication that can occur if the device is improperly placed or if excessive force is applied during insertion. However, it is not categorized as a common side effect, which speaks to the broader risks involved with airway management.

Thus, while infections can occur in a clinical setting, they aren't an immediate or inherent side effect of using the King LT/IGEL devices compared to the other listed options.
