Laparoscopic Lens Defogging Using Anti-fog Solution, waRm Saline, and Chlorhexidine Solution
- Conditions
- Gynecologic Disease
- Registration Number
- NCT03438890
- Lead Sponsor
- Kangbuk Samsung Hospital
- Brief Summary
The aim of this study is to compare three popular methods of minimizing or reducing laparoscopic lens fogging (LLF) by heating lens using warm saline, applying anti-fog agent to lens, and rubbing lens with chlorhexidine in laparoscopic gynecologic surgery.
- Detailed Description
The physiology behind laparoscopic lens fogging (LLF) is well understood based on meticulous experiments outlining the role of temperature and humidity. Despite many efforts, including uses of warm saline, various anti-fog agents, chlorhexidine, betadine, and rubbing the lens on serosal surfaces, to reduce LLF, there remains no consensus as to which method is superior to prevent LLF. Furthermore, most previous studies were experimental trials conducted in a simulation model or a non-human in vivo model or an expert's commentary based on their clinical experiences , and there was no randomized controlled trial focusing LLF in human model. Therefore, this randomized trial aimed to compare three popular methods of minimizing or reducing LLF by heating lens using warm saline, applying anti-fog agent to lens, and rubbing lens with chlorhexidine in laparoscopic gynecologic surgery.

- Primary Outcome Measures
Name Time Method the severity of LLF during the first 3-min operation At the time of surgery The severity of LLF was rated on a scale of 0 (the clearest) to 10 (the foggiest).
- Secondary Outcome Measures
Name Time Method total time to spend for lens cleaning At the time of surgery We will assess the total time to spend for lens cleansing at the time of surgery.
the number of lens cleansing At the time of surgery We will assess the number of lens cleansing at the time of surgery.
the severity of LLF occurred during the remaining operative time except the first 3-min At the time of surgery The severity of LLF was rated on a scale of 0 (the clearest) to 10 (the foggiest).
