The Postoperative Nausea and Vomiting (PONV) Intensity Scale was developed to define clinically important PONV. 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.
The PONV 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) PONV.
Thirty-nine patients (25%) had PONV at 6 hours and 54 (34%) had PONV at 24 hours. Thirty-six and 54 patients experienced nausea at 6 and 24 hours, respectively. Among patients with PONV, 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 PONV 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 PONV Intensity score.
The PONV Intensity Scale appears to be an accurate and reliable assessment and monitoring instrument for PONV in the PACU settings.
术后恶心呕吐（PONV）强度量表旨在定义具有临床重要意义的PONV。本研究的目的是对PONV强度量表进行翻译、回译并验证，以便在葡萄牙麻醉后护理单元（PACU）环境中使用。
根据现有指南对PONV强度量表进行翻译和回译。研究团队在一个PACU进行了一项观察性队列前瞻性研究。对术后三周内收治的157例成年患者进行PONV评估。测量指标包括术后6小时和24小时的恶心视觉模拟量表（VAS）。我们使用组内相关系数（ICC）和基于信息的分歧度量（IBMD）评估信度和观察者间的分歧。我们比较了具有临床显著意义（≥50）和无临床显著意义（<50）的PONV患者之间的VAS评分。
39例患者（25%）在6小时出现PONV，54例患者（34%）在24小时出现PONV。分别有36例和54例患者在6小时和24小时出现恶心。在出现PONV的患者中，分别有6例患者（15%）和9例患者（27%）在6小时和24小时的PONV强度量表评分具有临床显著意义。PONV强度量表评分和VAS的信度都很好，VAS的观察者间分歧略高。具有临床显著意义的PONV强度评分患者的恶心VAS评分中位数更高。
PONV强度量表似乎是PACU环境中评估和监测PONV的准确可靠工具。
