straight blade laryngoscopy
Direct laryngoscopy technique using a straight laryngoscope blade, preferred for pediatric intubation due to anatomical considerations.
Full Definition
Straight blade laryngoscopy is the preferred technique for direct laryngoscopy in pediatric patients, particularly infants and young children. Unlike curved blades used primarily in adults, straight blades (such as Miller or Wisconsin blades) are designed to directly lift the epiglottis and provide better visualization of the pediatric larynx. This technique accounts for the anatomical differences in children, including the relatively larger tongue, more anterior and cephalad larynx, and the more horizontal position of the vocal cords.
Usage
Usage note: Hyphenate when used as a compound modifier.
