Optimization of tissue adhesive curing time for surgical wound closure

Area of Science:

• Surgical Innovation
• Biomaterials Science
• Wound Healing Research

Background:

• Tissue adhesives (TAs) are widely used in surgery to supplement traditional wound closure methods.
• A significant drawback of TAs is the required drying time before dressing application, which prolongs operating time and reduces efficiency.
• Optimizing TA application is crucial for enhancing intraoperative workflow.

Purpose of the Study:

• To investigate practical methods for accelerating the curing time of 2-octyl cyanoacrylate (Dermabond) skin adhesive.
• To identify techniques that reduce the time from TA application to complete dryness.

Main Methods:

• Six distinct techniques were evaluated: control (no intervention), manual fanning, covering with a hand, using operating room lights, employing ultraviolet (UV) light, and prewarming the applicator in a hot water bath.
• Standardized amounts of 2-octyl cyanoacrylate were applied to a plexiglass surface under each condition.
• Drying times were recorded for ten replicates per technique to ensure statistical validity.

Main Results:

• The 'Covering,' 'OR Lights,' and 'Hot Water Bath' techniques demonstrated statistically significant reductions in drying time compared to the control group.
• Specifically, the 'Hot Water Bath' method showed the greatest reduction (30 seconds), followed by 'OR Lights' (27 seconds) and 'Covering' (25 seconds).
• Manual fanning and UV light exposure did not yield any significant decrease in the adhesive's drying time.

Conclusions:

• The application of 'Covering,' 'OR Lights,' or 'Hot Water Bath' techniques can effectively reduce the curing time of 2-octyl cyanoacrylate.
• These methods offer a practical approach to decrease overall operating time and enhance intraoperative efficiency for surgeons utilizing TAs.
• Further in vivo studies are recommended to confirm these findings in a clinical setting.
