Tumescent technique in digits: a subcutaneous single-injection digital block

Area of Science:

• Anesthesiology
• Hand Surgery
• Emergency Medicine

Background:

• A modified subcutaneous single-injection approach for digital block using a tumescent technique is presented.
• This technique aims to simplify and improve digital anesthesia for minor surgical interventions.

Purpose of the Study:

• To evaluate the safety and efficacy of a single-injection tumescent technique for digital nerve block.
• To assess the success rate and adverse events associated with this modified approach.

Main Methods:

• A convenient sample of 123 patients requiring digital anesthesia for minor procedures were enrolled.
• Digital nerve block was achieved by injecting 1% lidocaine into the volar subcutaneous space to induce a tumescent state.
• Success was defined by complete loss of sensation and ability to complete the procedure without pain; patients were followed for 1 month.

Main Results:

• The tumescent technique single-injection digital block was successful in all 123 digits studied.
• The procedures involved 39 volar and 84 dorsal lesions.
• No adverse events were reported during the 1-month follow-up period.

Conclusions:

• The tumescent technique is an easy, safe, and effective method for achieving digital anesthesia via a single injection.
• This technique is applicable for minor surgical procedures on fingers and thumbs, confirming its utility in clinical practice.
