Povidone-Iodine for Nasal Decolonization
- Conditions
- Methicillin-Resistant Staphylococcus AureusSurgical Wound InfectionPreoperative Care
- Interventions
- Drug: 0.9% NaCl Solution
- Registration Number
- NCT05529173
- Lead Sponsor
- Rutgers, The State University of New Jersey
- Brief Summary
To evaluate the efficacy and tolerability of 10% povidone-iodine in eliminating nasal carriage of Staphylococcus aureus and MRSA. To determine whether a more convenient, single-dose, pre-operative 10% povidone-iodine (PI) application is effective in reducing nasal carriage of S. aureus and MRSA. We expect a statistically significant decrease in S. aureus/MRSA colonization in nasal cultures taken perioperatively after intervention in patients who received pretreatment with PI as compared to patients who received normal saline (NS).
- Detailed Description
This will be a prospective single-blinded randomized placebo-controlled trial of two applications of a nasal 10% Povidone Iodine (PI) solution used on the intranasal mucosal surfaces of each nostril in the preoperative holding area within 2 h prior to surgical incision compared with NS using the same technique. Both the PI and NS will be applied by rotating the swab over the intranasal mucosal surface for 15 seconds; this process will be performed twice for both nostrils, using a new swab for each application. Nasal cultures will be obtained prior to PI or NS application as well as intraoperatively 1 hour and 2 hours after first surgical incision. The primary study end point is the decrease in S. aureus/MRSA colony forming units (CFU) in nasal cultures taken within 2 hours after intervention in patients who presented with a positive preintervention nasal culture. A secondary endpoint is the presence or absence of surgical site infections within 30 days postoperatively

- Primary Outcome Measures
Name Time Method Change in S. Aureus/MRSA Colony Forming Units (CFU) in Nasal Swab Specimen After Treatment in Patients Who Presented With a Positive for S. Aureus/MRSA Pre-interventional Nasal Swab Specimen. 1, 2, and 3 hours after application of Povidone-Iodine or saline solution The difference in a number of S. aureus/MRSA CFU in nasal swab specimens between before and after the study drug/placebo application in patients with a positive for S. aureus/MRSA pre-interventional nasal swab specimen. The change (Δ) is calculated as the value at the baseline time point minus the value at the later time point. Positive values represent a decrease in CFU, whereas negative values represent an increase in CFU.
- Secondary Outcome Measures
Name Time Method Surgical Site Infections at 7 and 30-day postoperative intervals The presence of surgical site infections
