Isopropyl alcohol nasal inhalation for nausea in the triage of an adult emergency department.

Abstract Objectives Nausea and vomiting (NV P, n = 56, intent-to-treat), three patients left the ED without being seen, and 115 patients completed the study. IPA and P groups were similar according to age, sex, comorbidities, and vital signs. We found that patients in the IPA group had significantly lower mean NRS starting with the 2nd minute (robust two-way mixed ANOVA between-subjects, p = 0.008). We also observed a significant within-subjects effect in the IPA group. The mean NRS value was decreased at each consecutive time point in the IPA group (all pairwise comparisons, p  Conclusion In this study, IPA was significantly more effective than P for N&V at the triage. Moreover, patients in the IPA group had less need for rescue treatment.
