Lee JH, et al. - Researchers analyzed 151 children to compare the incidence of gastric insufflation between pressure-controlled facemask ventilation and manual facemask ventilation during general anesthesia induction. They observed a significantly higher incidence of gastric insufflation in the MV group as compared to in the pressure-controlled ventilation group (48% vs 12% respectively). They also observed comparatively elevated mean peak airway pressure during ventilation in the manual ventilation group. Conclusively, they suggested pressure-controlled ventilation, more effective in comparison with manual ventilation in inhibiting gastric insufflation while providing stable ventilation, at an inspiratory pressure of 13 cmH₂O.
