Chlorhexidine Gluconate Versus Povidone-iodine (CHDvPI)

December 1, 2020 updated by: Gabriella Smith, University of Arizona

Effect of Chlorhexidine Gluconate Versus Povidone-iodine on the Vaginal Microbiome as Vaginal Operative Preparation During Gynecologic Surgeries

A hysterectomy, or removal of the uterus, is a common surgery performed for a variety of reasons. During this surgery, to prevent infection, the vagina is thoroughly prepped with a cleansing solution, most commonly chlorhexidine gluconate or povidone-iodine. While studies have shown that chlorhexidine gluconate is better at killing bacteria people have raised concerns on how it affects the vaginal tissue. It is important to study these effects the cleansing solution surgeons use for this surgery can not only prevent infection but not cause harmful side effects.

Study Overview

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

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Povidone-Iodine
Povidone-iodine to be used as the cleansing solution in this arm of patients for surgical vaginal preparation.
10% povidone-iodine vaginal cleansing solution as a surgical preparation.

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
