Kanawati index is used for –
**Core Concept**
Kanawati index is a clinical tool used to assess the severity of tracheal stenosis. It is a ratio-based measurement that helps clinicians evaluate the degree of tracheal narrowing and predict the risk of respiratory complications.
**Why the Correct Answer is Right**
The Kanawati index is calculated by dividing the length of the narrowed segment by the diameter of the trachea above the stenosis. This ratio helps clinicians assess the severity of tracheal stenosis and guide management decisions. The index is particularly useful in evaluating patients with tracheal stenosis who may require surgical intervention.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the Kanawati index is not used to assess laryngeal stenosis.
**Option B:** This option is incorrect because the Kanawati index is not a measure of tracheal diameter alone.
**Option C:** This option is incorrect because the Kanawati index is not a ratio of tracheal length to body height.
**Clinical Pearl / High-Yield Fact**
The Kanawati index is a useful tool for clinicians to assess the severity of tracheal stenosis and predict the risk of respiratory complications. It is essential to remember that a higher Kanawati index score indicates more severe tracheal stenosis.
**Correct Answer: D. Kanawati index is used for assessing tracheal stenosis.**
