Background: Breast surgery compromises one of the most common cancer surgeries in females and commonly followed by acute postoperative pain. Pregabalin and ketamine have been used in many previous studies and was found to have a good analgesic profile. We assumed that pregabalin and ketamine can be used in control of postoperative pain in female patients undergoing breast cancer surgery. Material and Methods: Ninety female patients scheduled for cancer breast surgery were allocated in three groups (30 patients each), control group (group c) received preoperative placebo, pregabalin group (group p) received oral 150 mg pregabalin 1 h before surgery, ketamine group (group k) received intravenous (IV) 0.5 mg/kg ketamine with induction of anesthesia followed by 0.25 mg/kg/h IV throughout the surgery. All patients received general anesthesia and after recovery, the three groups were assessed in the first postoperative 24 h for postoperative visual analog scale (VAS) , total 24 h morphine consumption, incidence of postoperative nausea and vomiting (PONV), sedation score >2 and any complications from the drugs used in the study. Results: The use of pregabalin or ketamine was found to reduce total postoperative morphine consumption with P < 0.001. There was no difference between pregabalin and ketamine groups in opioid requirement. There was no difference between the three groups in postoperative VAS scores or incidence of PONV and sedation score >2. Conclusion: The use of preoperative oral 150 mg pregabalin 1 h before surgery or IV 0.5 mg ketamine with induction of anesthesia can reduce postoperative opioid consumption in breast cancer surgery without change in sedation or PONV and with a good safety profile.
