Final answer:
The Cormack and Lehane Score is a grading system for glottic visualization during intubation, consisting of four grades that reflect the visibility of the glottis and assist healthcare professionals in assessing intubation difficulty.
Step-by-step explanation:
The Cormack and Lehane Score is (b) a grading system for glottic visualization during intubation. This score is used by anesthesiologists and other medical professionals to assess the difficulty of endotracheal intubation. The grading system consists of four grades, where Grade I represents a full view of the glottis, Grade II suggests that only the posterior part of the glottis can be seen, Grade III shows no glottis but only the epiglottis, and Grade IV indicates that neither the glottis nor epiglottis is visible.
The significance of this grading scale lies in its predictive value. A higher Cormack and Lehane Score correlates with increased difficulty of intubation, potentially requiring advanced airway management techniques or equipment. This grading system plays a vital role in guiding the management strategy and preparing for possible complications during the procedure.
