Carpal Tunnel Release Under Local Anaesthesia With or Without Distal Median Nerve Block

The anaesthetic cocktail consists of 1 ml of (7.5%) sodium bicarbonate (Natriumbicarbonate Braun 75mg/ml), 4,5 ml of lidocaine with adrenaline 1% (Lidocain cum adrenalin 10 mg/ml), 4,5 ml of bupivacaine with adrenaline 0.5% (Marcain cum adrenalin 5mg/ml +5 µg/ml). The anaesthetic cocktail must be prepared in the above-mentioned order to avoid possible precipitation. A 24-gauge hypodermic needle and 10 ml syringe are used to inject the solution. The care provider pinches from the area of median nerve blockade prior to performing local anaesthesia. All the anaesthetic solution is injected locally. Additional anaesthetic solution can be injected locally if necessary.
