Comparative StudyEffect of Paratracheal Pressure on the Glottic View During Direct Laryngoscopy: A Randomized Double-Blind, Noninferiority Trial.
Cricoid pressure has been used as a component of the rapid sequence induction and intubation technique. However, concerns have been raised regarding the effectiveness and safety of cricoid pressure. Paratracheal pressure, a potential alternative to cricoid pressure to prevent regurgitation of gastric contents or aspiration, has been studied to be more effective to cricoid pressure in preventing gastric insufflation during positive pressure ventilation. However, to adopt paratracheal compression into our practice, adverse effects including its effect on the glottic view during direct laryngoscopy should be studied. We conducted a randomized, double-blind, noninferiority trial comparing paratracheal and cricoid pressures for any adverse effects on the view during direct laryngoscopy, together with other secondary outcome measures. ⋯ Paratracheal pressure was noninferior to cricoid pressure with respect to the effect on glottic view during direct laryngoscopy.

Prediction of gastric fluid volume by ultrasonography in infants undergoing general anaesthesia.
Point-of-care ultrasonography can estimate gastric contents and volume to assess the risk of pulmonary aspiration; however, its use in infants has not been well validated. We aimed to develop a predictive model for estimating gastric fluid volume using ultrasonography in infants. ⋯ NCT03155776.

Long-term survival differences between sevoflurane and propofol use in general anesthesia for gynecologic cancer surgery.
This study aimed to evaluate the influence of anesthetic management with propofol or sevoflurane on the prognosis of patients undergoing gynecologic cancer surgery. ⋯ In patients undergoing gynecologic cancer surgery, sevoflurane anesthesia was associated with worse overall, cancer-specific, and recurrence-free survival than propofol anesthesia.

Observational StudyFactors associated with quality of dreams during general anesthesia: a prospective observational study.
Patients frequently report having dreams during general anesthesia, and the dreams are often reported to be pleasant dreams. However, factors associated with the quality of dreams during general anesthesia have not been clarified. The aim of this study was to determine the relationships between the quality of dreams during general anesthesia and perioperative factors. ⋯ A total of 1100 patients were included in the study, and 293 (25.4%) of the patients reported having dreams during anesthesia. Half of the patients who experienced dreams during anesthesia (50.2%, 147/293 patients) reported having a pleasant dream. Multivariate logistic regression analysis revealed that only HADS-depression score of less than 11 was related to pleasant dreams (OR: 3.3 [95% CI 1.3-10.0]).
