How to treat sympathetic nerves effectively

The sympathetic nerves are part of the autonomic nervous system. They play a very important role in the human body and are distributed in various parts of the human body. When the sympathetic nerves are excited or abnormal, they have a great impact on the human body. Sympathetic nerve problems can also be treated with medication.

① Local anesthetics or epidural block: If the upper limbs are affected, the ganglia below the stellate ganglion can be blocked. First inject 2-8 ml of normal saline. If it is ineffective within 15 minutes, inject 5 ml of 1% procaine (to block the sympathetic nerves). If the pain is still not relieved, inject 20-30 ml of 1% procaine into the brachial plexus sheath. For lower limb involvement, 5 ml of normal saline, 0.2% procaine (sympathetic nerve blocking concentration), 0.5% procaine (sensory nerve blocking concentration), and 1% procaine (motor nerve blocking concentration) can be injected epidurally every 10 minutes.

② Chemical drugs: The first drug used was guanethidine. 20 mg of guanethidine was injected locally intravenously 20 minutes after the tourniquet was applied to neutralize norepinephrine. Satisfactory results were achieved in all 12 cases. Schultzer et al. replaced guanethidine with reserpine for sympathetic nerve blockade and achieved similar results. Mckay achieved better results by adding calcitonin in addition to guanethidine. The effect of salmon calcitonin on sympathetic nerve blockade was unreliable, but it could prevent demineralization. Dellemijn used intravenous infusion of phentolamine for sympathetic blockade and achieved good results. Compared with stellate ganglion block, intravenous phentolamine has lower sensitivity but higher specificity. Mays treated 10 RSDS patients with planetary ganglion blockade using 2 mg of morphine diluted in 7 ml of saline, and found that 8 patients had complete remission and 7 patients had no relapse within 2 to 8 months.

③ Surgery: For patients who respond to multiple sympathetic nerve blocks but whose effects are short-lived, sympathectomy may be considered. Shumacker reported sympathectomy on 35 limbs of 34 RSDS patients. All patients were cured except for 4 patients who had mild sequelae. Week summarized the efficacy of sympathectomy for RSDS in 231 cases by 6 authors, and the effective rate was 82%.
