However, its effectiveness and safety have been questioned. Paratracheal pressure (PP) has emerged as a\u00a0potential alternative. This study aimed to compare the\u00a0adverse effects of\u00a0PP versus CP on the\u00a0glottic view during direct laryngoscopy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and methods<\/jats:title>\n                    <jats:p>This randomized, double-blind, non-inferiority trial included 200 adult patients undergoing general anaesthesia. Participants were randomly assigned to receive either PP or CP during anaesthesia induction. The\u00a0primary endpoint was the\u00a0incidence of\u00a0deteriorated laryngoscopic view, assessed by a\u00a0blinded observer using the\u00a0modified Cormack-Lehane grade with a\u00a0non-inferiority margin of\u00a0\u201310%. Secondary endpoints included the\u00a0percentage of\u00a0the\u00a0glottic opening score, ease of\u00a0mask ventilation, changes in ventilation volume and peak inspiratory pressure (PIP) during mechanical mask ventilation, ease of\u00a0tracheal intubation, and resistance during tube advancement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>PP was found to be non-inferior to CP regarding the\u00a0incidence of\u00a0deteriorated laryngoscopic view (0% vs. 20%; absolute risk difference, \u221220%; 2-sided 95% CI, \u221226.68 to \u201313.32; P &lt; 0.001). Mask ventilation was easier with PP (OR, 0.60; 95% CI, 0.15\u20132.17; P = 0.284). The\u00a0increase in PIP was significantly smaller in the\u00a0paratracheal group (0.47 (0.31\u20130.63) vs. 1.46 (1.22\u20131.69); P = 0.002).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>PP is non-inferior to CP concerning its effect on the\u00a0glottic view during direct laryngoscopy.
