Chlorhexidine Gluconate Versus Povidone-iodine (CHDvPI)
Effect of Chlorhexidine Gluconate Versus Povidone-iodine on the Vaginal Microbiome as Vaginal Operative Preparation During Gynecologic Surgeries
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
The purpose of this study is to examine the effects of different vaginal operative preparations on the vaginal tissue and microbiome. Our primary working hypothesis is that chlorhexidine prep is more deleterious to vaginal tissue than povidone-iodine preparations.
Hypothesis 1: chlorhexidine gluconate is more disruptive to the vaginal microbiome than povidone-iodine Hypothesis 2: chlorhexidine gluconate leads to more vaginal atrophy than povidone-iodine

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Frequency of patient-reported vaginal and urinary symptoms after treatment with chlorhexidine gluconate or povidone-iodine vaginal cleansing solution
Time Frame: From date of surgery to 24 hours post-operative
|
To compare the frequency of patient-reported vaginal and urinary symptoms after treatment with chlorhexidine gluconate or povidone-iodine vaginal cleansing solution utilizing questionnaires.
|
From date of surgery to 24 hours post-operative
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Relative abundances of vaginal microbiota species
Time Frame: From date of surgery to 3-6 weeks postoperative
|
To measure the change in relative abundances of vaginal microbiota species after treatment with chlorhexidine gluconate or a povidone-iodine vaginal cleansing solution.
Vaginal microbiota species include but not limited to health-associated Lactobacillus spp., bacterial-vaginosis associated anaerobes (Gardnerella, Prevotella, Sneathia, Atopobium, Megasphaera, Parvimonas, Mobiluncus and others), pathobionts (Streptococcus, Escherichia), and other bacterial taxa present in the collected vaginal swabs using 16S rRNA sequencing
|
From date of surgery to 3-6 weeks postoperative
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in level of genital cytokines and chemokines
Time Frame: From date of surgery to 3-6 weeks post-operative
|
To measure the change in levels of genital cytokines and chemokines (IL-1alpha, IL-1beta, IL-8, MIP-1beta, MIP-3alpha, RANTES, TNFalpha) in the collected cervicovaginal lavages using multiplex cytometric bead arrays after treatment with chlorhexidine gluconate or a povidone-iodine vaginal cleansing solution.
The cytokine levels will be used to determine the genital inflammatory score by using a previously described genital inflammation scoring system.
Patients will be assigned one point for each mediator when the level was in the upper quartile
|
From date of surgery to 3-6 weeks post-operative
|
Change in vaginal pH level
Time Frame: From date of surgery to 3-6weeks post-operative
|
To measure the change vaginal pH after treatment with chlorhexidine gluconate or a povidone-iodine vaginal cleansing solution.
|
From date of surgery to 3-6weeks post-operative
