Percutaneous anaesthesia for some minor surgical procedures

Area of Science:

• Anesthesiology
• Dermatology
• Surgical Procedures

Background:

• Topical anesthesia is crucial for pain management during minor surgical excisions.
• Evaluating novel anesthetic formulations for improved clinical efficacy and patient comfort is an ongoing area of research.
• Ketocaine, a ketamine-based anesthetic, has been explored for various applications, including topical anesthesia.

Purpose of the Study:

• To assess the anesthetic efficacy of four distinct ketocaine formulations applied epicutaneously for minor surgical excisions.
• To identify the most clinically suitable ketocaine formulation for topical anesthesia in minor surgical procedures.
• To determine the limitations and potential applications of the preferred ketocaine formulation.

Main Methods:

• An initial pin-pricking study was conducted to evaluate sensory response.
• Clinical trials involving 60 patients undergoing minor surgical excisions were performed.
• Comparative analysis of four ketocaine formulations based on anesthetic effectiveness and patient outcomes.

Main Results:

• One specific ketocaine formulation demonstrated superior clinical performance compared to the other three.
• Out of 20 patients receiving the preferred formulation, 16 underwent surgery without the need for complementary anesthesia.
• The depth of anesthesia achieved with the preferred formulation was variable, necessitating caution.

Conclusions:

• The preferred ketocaine formulation shows promise for topical anesthesia in minor surgical excisions.
• Its application is primarily recommended for relatively superficial operations due to variable anesthesia depth.
• Further research may be needed to optimize formulation and application for deeper anesthesia.
