Current medical training recommends obtaining cervical cytological specimens without the use of lubricating gel. The purpose of this study was to determine whether water-soluble lubricant gel affects cytologic outcomes in the screening Papanicolaou smear and patient comfort during vaginal speculum examination.
The study was a randomized controlled trial performed at David Grant US Air Force Medical Center (Travis Air Force Base, CA). Participants were female patients at least 18 years old presenting for an annual Papanicolaou smear. Each patient, blinded to group assignment, consented to two consecutive Papanicolaou smears. The first Papanicolaou smear was performed without gel in all subjects as part of the "standard of care." Thirty control patients underwent a second examination with no gel, and 40 other patients had the second examination with gel. All patients rated the discomfort of each Papanicolaou smear on a numerical pain scale. Main outcome measures were cytologic discrepancies on standard glass slide samples and comfort differences regarding the use of gel lubrication. Fisher's exact test was used to interpret the effect of gel on cytology results. Student's t test was performed to compare the discomfort ratings for the second Papanicolaou smear in the GEL vs. the NO GEL groups.
There was no statistically significant difference between the number of inadequate Papanicolaou smears (P = .50) nor in the discomfort level ratings in the GEL vs. the NO GEL groups (P = .69).
Speculum gel lubrication does not affect cervical cytology during the traditional Papanicolaou smear, nor does it provide significant alteration of patient discomfort.
当前医学培训建议在不使用润滑凝胶的情况下获取宫颈细胞学标本。本研究的目的是确定水溶性润滑凝胶在巴氏涂片筛查中是否会影响细胞学结果以及阴道窥器检查期间患者的舒适度。
该研究是在大卫·格兰特美国空军医疗中心(加利福尼亚州特拉维斯空军基地)进行的一项随机对照试验。参与者为至少18岁前来进行年度巴氏涂片检查的女性患者。每位患者对分组情况不知情,同意连续进行两次巴氏涂片检查。作为“护理标准”的一部分,所有受试者的第一次巴氏涂片检查均不使用凝胶。30名对照患者第二次检查不使用凝胶,另外40名患者第二次检查使用凝胶。所有患者用数字疼痛量表对每次巴氏涂片检查的不适程度进行评分。主要观察指标是标准载玻片样本上的细胞学差异以及使用凝胶润滑的舒适度差异。采用Fisher精确检验来解释凝胶对细胞学结果的影响。进行学生t检验以比较凝胶组与无凝胶组第二次巴氏涂片检查的不适评分。
巴氏涂片检查不合格的数量在凝胶组与无凝胶组之间无统计学显著差异(P = 0.50),不适程度评分也无显著差异(P = 0.69)。
在传统巴氏涂片检查中,窥器凝胶润滑不影响宫颈细胞学检查结果,也不会显著改变患者的不适程度。
