Tumescent local anaesthesia is a technique that provides local and regional anaesthesia of large areas of the skin and subcutaneous tissue, using direct infiltration of large volumes of a diluted solution of local anaesthetic. The use of tumescence anaesthesia during radiofrequency ablation and laser ablation for varicose veins has allowed for procedures to be performed in outpatient settings. The Dispenser DP 30 is a tumescence infiltration pump, specifically designed for varicose vein treatment, precisely delivering tumescence liquid with an optimal adjusted pressure.
