To determine how parturient women tolerate the use of a perineal distensibility assessment technique using the EPI-NO device.
An observational study with a total of 227 full-term parturient women was performed. During the evaluation with EPI-NO, parturient patients were asked about their sensation of discomfort. The degree of discomfort was measured using the Visual Analogue Scale, with a score from zero to 10. The Mann-Whitney test was applied to assess perineal distensibility measured by EPI-NO and the degree of discomfort caused by the test according to parity. The relation between perineal distensibility and discomfort was analyzed by using the Spearman correlation test (r).
The test with EPI-NO caused only slight discomfort (mean Visual Analogue Scale of 3.8), and primiparous women reported significantly greater discomfort (mean Visual Analogue Scale of 4.5) than did multiparous (mean Visual Analogue Scale=3.1), with p<0.001 women. A negative correlation was observed, in other words, the greater the perineal distensibility on the EPI-NO, the lower the pain reported by the patients (r=-0.424; p<0.001).
The assessment of perineal distensibility with EPI-NO was well tolerated by the parturient women.
确定产妇对使用EPI-NO装置的会阴扩张性评估技术的耐受程度。
对总共227名足月产妇进行了一项观察性研究。在使用EPI-NO进行评估期间，询问产妇患者的不适感觉。使用视觉模拟量表测量不适程度，分数范围为0至10。应用曼-惠特尼检验，根据产次评估EPI-NO测量的会阴扩张性以及该测试引起的不适程度。使用斯皮尔曼相关性检验（r）分析会阴扩张性与不适之间的关系。
使用EPI-NO进行测试仅引起轻微不适（视觉模拟量表平均分为3.8），初产妇报告的不适程度（视觉模拟量表平均分为4.5）明显高于经产妇（视觉模拟量表平均分为3.1），p<0.001。观察到负相关，也就是说，EPI-NO测量的会阴扩张性越大，患者报告的疼痛越低（r=-0.424；p<0.001）。
产妇对使用EPI-NO评估会阴扩张性的耐受性良好。
