Intubation depth markings allow an improved positioning of endotracheal tubes in children

Abstract

O Ob bj je ec ct ti iv ve es s: : To evaluate the position of the new Microcuff® pediatric tracheal tube, based upon intubation depth markings.

Utilizing Nasal-Tragus Length to Estimate Optimal Endotracheal Tube Depth for Neonates in Taiwan

“…Loew et al described the placement of the safety marking, a black safety area known as the "vocal cord localizer", on the ETT tip [16]. However, the length of black area on the tube tip differs from each manufacturer; some adjust the length according to the ETT sizes for different infants, and the others just provide a visualized area for rapidly recognizing the ETT tip [17,18]. This might lead to unexpected misplacement of ETT and potential hazard.…”

Oral endotracheal intubation in pediatric anesthesia

“…However, Microcuff ETTs are not currently available for preterm infants or those that weigh < 3 kg. Placement of imprinted depth markings on the cuff between the vocal cords makes it possible to locate the Microcuff ETT safely within the cuff-free laryngeal zone without risking endobronchial intubation, which provides results superior to those obtained based on the predicted insertion location using a standard formula [13]. This results in a reduced rate of exchange (from 25% to 2%) of ETTs after intubation in pediatric anesthesia [14].…”
