Summary

Cesarean birth is a common surgical procedure. After cesarean birth, postsurgical pain may delay recovery, interfere with maternal-newborn bonding, and reduce the breastfeeding if not adequately controlled. Postpartum analgesia has become a common concern.

Many adjuvant drugs used for peripheral nerve blocks as( N-methyl-d-aspartate (NMDA) receptor antagonists , Magnesium , Ephedrine , Dexamesathone , Fentanyl , Midazolam and Neostigmine) The potential of neostigmine as an adjuvant in peripheral nerve block is through its action to increase acetylcholine at muscarinic junctions of peripheral nerves. 500 mcg neostigmine was used as adjuvant to local anesthetic in an axillary brachial plexus block leads to decreased pain and less use of analgesics in the first 24 hours postoperatively with no incidence of adverse effects.
