Utility of Adult Miller Blade

Skillful airway management is an essential prerequisite for orotracheal intubation both in emergencies and elective surgeries requiring general anesthesia.Both Miller and Macintosh blades are very commonly and widely used for intubations in all patient age groups, though the Macintosh blade is more commonly recommended in the adult population and the Miller blade in the pediatric population as evidenced in the existing literature.A better view of the glottis is obtained with the adult straight Miller blade as it has a narrow tip and hence gives a wider working space to negotiate an endotracheal tube that leads to an improved line of sight to the glottis.A review of the literature was conducted to summarize existing evidence of the adult Miller on ease of orotracheal intubation, glottic view, time taken for intubation, and hemodynamic changes, and there is very little literature comparing the Miller blade and Macintosh blade use in the adult population.
