Effect of a Topical Ketamine on Acute and Chronic Pain, Dose Finding

Brief Summary

The aim of this study is to investigate the effect of addition of different doses of Ketamine locally in acute and chronic post-mastectomy pain after breast cancer surgery and on the probability of developing chronic post-mastectomy pain.

Intervention / Treatment

  • group (A) (DRUG)
    patients will receive 1mg / kg of Ketamine diluted by 20 ml saline (0.9 % ) and irrigated onto surgical field after hemostats and before skin closure.
  • group (B) (DRUG)
    patients will receive 2 mg /kg of Ketamine diluted by 20 ml saline (0.9 %) and irrigated onto surgical field after hemostasis and before skin closure.
  • group (c) (DRUG)
    patients will receive 3 mg /kg of Ketamine diluted by 20 ml saline (0.9 %) and irrigated onto surgical field after hemostasis and before skin closure.
