modified Cormack-Lehane grade
Pronunciation: CORE-mack LEE-hayn
Pediatric adaptation of the laryngoscopic view classification system accounting for anatomical differences in children.
Full Definition
The modified Cormack-Lehane grade is an adaptation of the standard laryngoscopic view classification specifically validated for pediatric patients. The system grades laryngeal visualization from Grade I (complete glottis visible) to Grade IV (no laryngeal structures visible), but pediatric modifications account for the relatively larger occiput, more anterior larynx, and proportionally larger tongue in children. Some pediatric versions include intermediate grades (IIa, IIb) for more precise classification. This grading system helps predict intubation difficulty and guides airway management decisions in pediatric patients.
Usage
Usage note: Use pediatric-specific modifications rather than adult Cormack-Lehane classification for accuracy in children.
