Summary
The Fluid Warming System demonstrated fewer lens fogging events during laparoscopic procedures compared to the Clearify Visualization System. Both methods showed similar surgery duration and cost, making the Fluid Warming System more efficient.
Area of Science:
- Laparoscopic surgery
- Surgical visualization
- Medical device evaluation
Background:
- Lens fogging is a common challenge in laparoscopic surgery, potentially impairing visualization.
- Effective management of lens fogging is crucial for maintaining surgical field clarity and efficiency.
- Two commercially available systems, Fluid Warming System and Clearify Visualization System, are commonly used to address this issue.
Purpose of the Study:
- To compare the efficiency and efficacy of the Fluid Warming System and the Clearify Visualization System in resolving lens fogging during laparoscopic procedures.
- To evaluate the impact of each system on surgical visualization and operative workflow.
- To analyze the cost-effectiveness of both lens fogging prevention methods.
Main Methods:
- A prospective study involving 40 patients undergoing laparoscopic renal procedures.
- The first 20 cases utilized the Fluid Warming System with a modified 30-second protocol.
- The subsequent 20 cases employed the Clearify Visualization System according to manufacturer instructions. Etiology of visual obstruction, procedure type, surgery duration, and cost were documented.
Main Results:
- Both systems were used successfully in all 40 patients without complications.
- The Fluid Warming System showed a significantly lower mean fogging events per hour (0.7) compared to the Clearify Visualization System (1.4) (P=0.045).
- There were no significant differences in surgery duration or cost per procedure between the two systems.
Conclusions:
- The Fluid Warming System, when used with a modified technique, proved more effective in reducing lens fogging events during laparoscopic surgery.
- No significant differences in operative time or procedural costs were observed between the Fluid Warming System and the Clearify Visualization System.
- The Fluid Warming System offers a more efficient solution for managing lens fogging in laparoscopic procedures.
