Abstract

The invention belongs to the field of medicine, and discloses a composition for childbirth containing procaine. The composition adopts injections, and every 100 milliliters of injections consists of 30-40 mg of procaine, 0.03-0.07 mg of epinephrine, Fentanyl 0.01-0.05mg, atropine 0.2-0.8mg, sodium chloride 1-5mg, hydrochloric acid 1-10mg and the balance of water for injection. The present invention is used for labor analgesia, which is easy to administer, has quick onset, reliable effect, no toxic and side effects, and can meet the needs of the whole labor analgesia. Compared with the prior art, the action time of procaine is prolonged, and It can correspondingly reduce the bleeding in the operation area, avoid the poisoning reaction caused by high blood drug concentration, and eliminate the inhibition of respiration by procaine.

Description
