Abstract (EN): Background and objectives: The Postoperative Nausea and Vomiting (PONY) Intensity Scale was developed to define clinically important PONY. The aim of this study was to translate, retranslate and validate the PONV Intensity Scale for use in Portuguese Post Anesthetic Care Unit (PACU) settings. Methods: The PONY Intensity Scale was translated and back-translated in accordance with available guidelines. The research team conducted an observational and cohort prospective study in a PACU. One-hundred fifty-seven adult patients admiited after surgery over three weeks were evaluated for PONV. Measurements included nausea visual analogic scale (VAS) at 6 and 24 hours, postoperatively. We assessed reliability and observer disagreement using interclass correlation (ICC) and Information-Based Measure of Disagreement (IBMD). We compared VAS scores between patients with clinically significant (50) and not significant (<50) PONY. Results: Thirty-nine patients (25%) had PONY at 6 hours and 54 (34%) had PONY at 24 hours. Thirty-six and 54 patients experienced nausea at 6 and 24 hours, respectively. Among patients with PONY, 6 patients (15%) and 9 patients (27%) had a clinically significant PONV intensity scale score at 6 and at 24 hours, respectively. The reliability was good both for PONY intensity scale score and for VAS and observer disagreement was slightly higher for VAS. The median nausea VAS scores were higher in patients with clinically significant PONY Intensity score. Conclusions: The PONY Intensity Scale appears to be an accurate and reliable assessment and monitoring instrument for PONY in the PACU settings.
