Do I need to sign a doctor's order for nerve block anesthesia

Nerve block anesthesia requires a doctor's order.

Nerve block anesthesia refers to the injection of a local anesthetic near the peripheral nerve stem to numb the area innervated by the nerve by blocking the conduction of nerve impulses. There are two main contraindications for nerve block anesthesia:

1. The patient has severe hypokalemia or recent coronary heart disease.

2. Skin infection, ulceration or peripheral nerve lesions at the puncture site. If anesthesia is performed with contraindications, it can lead to infection, loss of nerve function and neuropathy. If necessary, avoid diseased skin and nerves
