有创动脉血压(IAP)和无创血压(NIBP)测量都是常见的方法。最近,提出了一种新的误差网格分析方法,用于比较使用两种测量方法获得的血压。本研究旨在使用误差网格分析比较IAP和NIBP测量值,并研究影响IAP和NIBP之间差异的潜在混杂因素。
对仰卧位全身麻醉并同时测量IAP和NIBP的成年患者进行回顾性调查。进行误差网格分析以比较IAP和NIBP。在误差网格分析中,评估了IAP和NIBP之间差异的临床相关性,并将其分为5个区域,从无风险(A)到危险风险(E).
总的来说,收集了来自100例患者的1934个IAP/NIBP测量对的数据.误差网格分析显示,A-E区占收缩压的比例为96.4%,3.5%,0.05%,0%,0%,分别。相比之下,平均血压的比例为82.5%,16.7%,0.8%,0%,0%,分别。多元回归分析显示,连续给予去氧肾上腺素(p=0.016)和年龄(p=0.044)是平均血压差异的临床风险增加的重要因素。
误差网格分析表明,IAP和NIBP之间的平均血压差异在临床上不可接受,并且有导致不必要治疗的风险。持续的去氧肾上腺素给药和年龄是IAP和NIBP之间差异的临床风险增加的重要因素。
Invasive arterial blood pressure (IAP) and noninvasive blood pressure (NIBP) measurements are both common methods. Recently, a new method of error grid analysis was proposed to compare blood pressure obtained using two measurement methods. This study aimed to compare IAP and NIBP measurements using the error grid analysis and investigate potential confounding factors affecting the discrepancies between IAP and NIBP.
Adult patients who underwent general anesthesia in the supine position with both IAP and NIBP measurements were retrospectively investigated. The error grid analyses were performed to compare IAP and NIBP. In the error grid analysis, the clinical relevance of the discrepancies between IAP and NIBP was evaluated and classified into five zones from no risk (A) to dangerous risk (E).
Overall, data of 1934 IAP/NIBP measurement pairs from 100 patients were collected. The error grid analysis revealed that the proportions of zones A-E for systolic blood pressure were 96.4%, 3.5%, 0.05%, 0%, and 0%, respectively. In contrast, the proportions for mean blood pressure were 82.5%, 16.7%, 0.8%, 0%, and 0%, respectively. The multiple regression analysis revealed that continuous phenylephrine administration (p = 0.016) and age (p = 0.044) were the significant factors of an increased clinical risk of the differences in mean blood pressure.
The error grid analysis indicated that the differences between IAP and NIBP for mean blood pressure were not clinically acceptable and had the risk of leading to unnecessary treatments. Continuous phenylephrine administration and age were the significant factors of an increased clinical risk of the discrepancies between IAP and NIBP.
