An improved technique of local anal anesthesia

Area of Science:

• Anesthesiology
• Surgical Innovation

Background:

• Perianal anesthesia is crucial for minor proctologic procedures.
• Current methods often require multiple, separate anesthetic injections, which can be time-consuming and less efficient.

Purpose of the Study:

• To introduce and evaluate a novel four-needle anesthetic injector.
• To assess the efficacy of this device in simplifying perianal anesthesia for proctologic procedures.

Main Methods:

• Development of a specialized four-needle anesthetic injector.
• Application of the injector for delivering local anesthesia in minor proctologic surgeries.

Main Results:

• The four-needle injector allows for simultaneous administration of anesthetic in multiple sites.
• This technique effectively obviates the need for repeated, individual injections.
• Potential for reduced procedure time and improved patient comfort.

Conclusions:

• The four-needle anesthetic injector offers a streamlined approach to perianal anesthesia.
• This device represents a significant advancement in the delivery of anesthesia for proctologic interventions.
