Clinical Trial Summary

Medical thoracoscopy is the preferred procedure for performing pleural biopsy in patients with pleural effusions that remain undiagnosed after pleural fluid analysis. Surgical site infections (SSI) and empyema are among the important complications of the procedure.

At author's center, povidone-iodine is used for surgical site preparation during MT. The investigators hypothesized that chlorhexidine-alcohol would be superior to povidone-iodine in reducing the rate of infectious complications following thoracoscopy. In this study, the authors propose to investigate the efficacy of chlorhexidine-alcohol scrub in preventing post procedural infectious complications in subjects undergoing medical thoracoscopy

Description:

Medical thoracoscopy is the preferred procedure for performing pleural biopsy in patients with pleural effusions that remain undiagnosed after pleural fluid analysis. Unlike video-assisted thoracoscopic surgery that is performed under general anesthesia and single lung ventilation, medical thoracoscopy is performed under conscious sedation and local anesthesia. Medical thoracoscopy is generally a safe procedure, albeit with a small risk of complications. Surgical site infections (SSI) and empyema are among the important complications of the procedure. Author's center is a tertiary care referral hospital; the majority of the patients are referred to the authors' center late in the course of their illness. In fact, most patients have had several thoracenteses, and many patients have pleural adhesions. The authors have observed a significant incidence of post procedural infections (7.8-10%) in previous studies. In a recent RCT, investigators have demonstrated that the prophylactic use of antibiotics did not reduce the incidence of SSI. Since the patient's skin is a major source of pathogens, it is conceivable that improving skin antisepsis would decrease surgical-site infections. The aim of preoperative skin preparation is to reduce the risk of SSIs by removing soil and transient organisms from skin. Antiseptics have the ability to bind to the skin's stratum corneum that results in persistent chemical activity on the skin. A SSI occurs when the number of bacteria at the incision site overcome the hosts immune defense mechanism. The Centers for Disease Control and Prevention (CDC) recommends that 2% chlorhexidine-based preparations be used to cleanse the site of insertion of vascular catheters. However, the CDC has not issued a recommendation as to which antiseptics should be used preoperatively to prevent postoperative SSIs.

In a previous RCT comparing preoperative cleansing of the patient's skin, chlorhexidine-alcohol was found to be superior to cleansing with povidone-iodine for preventing surgical-site infection after clean contaminated surgery. However, in a pooled analysis of 13 RCTs comparing surgical site preparation for clean surgeries, no clear benefit could be demonstrated of either agent for preventing SSIs. Also, no published randomized studies have examined the effect of one antiseptic preparation over another on the incidence of surgical-site infection during medical thoracoscopy. A recent guideline on medical thoracoscopy has no mention about the preferred agent for skin preparation during MT. At the author's center, povidone-iodine is used for surgical site preparation during MT. The authors hypothesized that chlorhexidine-alcohol would be superior to povidone-iodine in reducing the rate of infectious complications following thoracoscopy. In this study, the investigators propose to investigate the efficacy of chlorhexidine-alcohol scrub in preventing post procedural infectious complications in subjects undergoing medical thoracoscopy.
