The purpose of this study was to compare the rates of bacteriuria in laboring women with epidural analgesia with the use of intermittent bladder catheterization (IC) vs continuous indwelling Foley catheterization (CIF).
We conducted a randomized, nonblinded trial in which 160 laboring women received IC or CIF. An initial catheterized urine culture was taken at the time of epidural placement. A second catheterized or voided culture was taken at discharge. Results were analyzed to compare bacteriuria rates between CIF and IC with the use of the Center for Disease Control (CDC) and Infectious Disease Society of America (IDSA) definitions.
Samples from 146 women were analyzed. Randomization, demographics, and labor characteristics were not significantly different between groups; 5.48% of the samples met CDC criteria for bacteriuria, and 17.8% of the samples met IDSA criteria. In the IC group, 7 samples (8.9%) met CDC criteria for bacteriuria, and 18 samples (22.8%) met IDSA criteria for bacteriuria. In the CIF group, 1 sample (1.5%) met CDC criteria, and 8 samples (12.1%) met IDSA criteria. There was a significantly higher rate of bacteriuria by both criteria in the IC group among all deliveries, all vaginal deliveries, and spontaneous vaginal deliveries (P < .05).
Compared with CIF, IC was associated with significantly higher rates of bacteriuria.
本研究旨在比较硬膜外镇痛分娩产妇中间歇性导尿（IC）与连续留置 Foley 导管（CIF）的菌尿发生率。
我们进行了一项随机、非盲试验，其中 160 名产妇接受 IC 或 CIF。在硬膜外放置时采集初始导尿管尿液培养物。在出院时采集第二次导尿或排尿培养物。结果分析比较了 CIF 和 IC 之间的菌尿率，使用了疾病控制和预防中心（CDC）和感染病学会（IDSA）的定义。
对 146 名女性的样本进行了分析。随机分组、人口统计学和分娩特征在组间无显著差异；5.48%的样本符合 CDC 菌尿标准，17.8%的样本符合 IDSA 菌尿标准。在 IC 组中，7 个样本（8.9%）符合 CDC 菌尿标准，18 个样本（22.8%）符合 IDSA 菌尿标准。在 CIF 组中，1 个样本（1.5%）符合 CDC 标准，8 个样本（12.1%）符合 IDSA 标准。在所有分娩、所有阴道分娩和自然阴道分娩中，IC 组的两种标准下的菌尿率均显著更高（P<.05）。
与 CIF 相比，IC 与菌尿发生率显著升高相关。
