[Gastric fluid volume and pH in scheduled surgical patients following unrestricted oral fluid intake until two hours before surgery].

Background: In scheduled surgery, drinking is generally restricted for 6-8 hours before operation to avoid aspiration pneumonia induced by aspiration of residual gastric contents. However, the restriction is hard for patients and also there is no evidence of reduction of such a risk. We examined the correlation between water intake and residual gastric content.

The effects of chin lift and jaw thrust while in the lateral position on stridor score in anesthetized children with adenotonsillar hypertrophy.

Obstruction of the upper airway is a major challenge for anesthesiologists administering general anesthesia in spontaneously breathing patients, especially in pediatric anesthesia with adenotonsillar hypertrophy. Lateral positioning is a simple treatment for obstructive sleep apnea and also decreases collapsibility of the pharynx in anesthetized adults with obstructive sleep apnea. In this study, we examined the effects of body position shifting and common airway maneuvers, such as chin lift and jaw thrust, on airway patency (stridor score) in anesthetized children scheduled for adenotonsillectomy.
