ABSTRACT
The possible operating time is short, no longer than one hour. Additionally, when the tourniquet is released, there is no longer any possibility of performing hemostasis. In case of lacerations, the wound edges are injected. A needle can also be used directly in the wound. Deposit a small amount of approximately 2 mL on both sides on the volar aspect. The thumb can also be anesthetized by means of Oberst’s anesthesia, but the dorsal site must also be injected due to a separate nerve innervation. A bloodless field can be created by applying a small tourniquet on the finger proximally with a silicone drain. Place a clamp on the drain such that the drain does not accidentally disappear under the dressing. Conduction anesthesia in the form of a brachial plexus block is performed by experienced anesthetists or hand surgeons. Generating paresthesia at a peripheral nerve with an ordinary hypodermic needle is undesirable because it can cause nerve damage.
