History of Changes

Purpose

Prevalence of chronic pain after mastectomy is beyond 50% 3 months after surgery. This pain is related to a sensitization of the central nervous system through N-methyl-D-asparate (NMDA) receptors. Ketalar might prevent the occurrence of chronic pain by anti-NMDA properties after mastectomy.
