However, the POGO scores with the Macintosh blade lifting the epiglottis were significantly greater than those lifting the tongue base. The POGO scores with the Miller blade were similar lifting the epiglottis and the tongue base. RESULTS: The POGO scores with the Miller blade were significantly greater than those with the Macintosh blade, while lifting both the epiglottis and the tongue base (P=0.0001) (Figure). Data are summarized as means ± 95% confidence interval (CI) or standard deviation as indicated. 2 Cardiorespiratory variables were also recorded before and after tracheal intubation.
The glottic views were photographed, and the photographs were then de-identified, randomized and then reviewed by a blinded anesthesiologist using the percent of glottic opening (POGO) score. All glottic views were optimized using external laryngeal manipulation the paraglossal approach was used with the Miller blade. Two glottic views were obtained with the same blade in each neonate: lifting the epiglottis and lifting the tongue base.
METHODS: After institutional review board approval and registration (ACTRN12619000151134), 40 full-term neonates undergoing elective surgery were enrolled and randomized to either the Miller or Macintosh size 0 blade and then randomized again to lifting the epiglottis or tongue base first and the other second. Therefore, we compared the glottic views with the Miller and Macintosh size 0 blades, lifting either the epiglottis or the tongue base in neonates. 1 However, the Miller and Macintosh size 0 laryngoscope blades have not been compared in neonates who require tracheal intubation.
INTRODUCTION: Both the Miller and Macintosh blades are commonly used to view the larynx in infants and children. Other Material Support Self Patent holder, Linshom LLC.
