[Pubic tubercle side approach to the obturator nerve block]

Area of Science:

• Urology
• Anesthesiology
• Surgical Techniques

Background:

• Adductor muscle constriction is a common complication during transurethral resection of bladder tumors.
• Obturation nerve blocks are used to manage this complication.
• The pubic tubercle side approach is a novel technique for performing this nerve block.

Purpose of the Study:

• To describe and evaluate the efficacy of the pubic tubercle side approach for obturator nerve block.
• To compare this new approach with the traditional method in terms of anesthetic dosage and success rate.

Main Methods:

• The pubic tubercle side approach involves needle insertion between the femoral artery and pubic tubercle, with redirection towards the superior pubic ramus.
• Obturation nerve identification is confirmed via nerve stimulation.
• A single injection of 1.0% lidocaine is administered until nerve stimulation response ceases.

Main Results:

• The pubic tubercle side approach demonstrated a higher success rate compared to the traditional method.
• This novel approach required a smaller volume of local anesthetic.
• No complications were reported with the pubic tubercle side approach.

Conclusions:

• The pubic tubercle side approach for obturator nerve block is an effective and safe alternative.
• It offers advantages over the traditional approach, including reduced anesthetic use and improved efficacy.
• This technique is beneficial for managing adductor muscle spasms in patients undergoing transurethral resection of bladder tumors.
