Objectives:
Preventive analgesia has been defined as reduction in noxious stimuli during preoperative, intraoperative, and postoperative periods. The aim of the present study was to prevent central sensitization by administering ketamine infusion throughout the surgical procedure. In addition, possible preventive effects of dexketoprofen when administered before and after incision were evaluated.
Methods:
Fifty patients were included. Group I was administered 50 mg intravenous dexketoprofen prior to surgical incision, and Group II received the same amount 10 minutes after the incision had been made. Following induction of general anesthesia, all patients received a bolus of 0.50 mg/kg ketamine in 0.07 mg/kg/h intravenous infusion.
Results:
When postoperative visual analog scale values were compared, values for Group I after 1 and 4 hours were significantly lower than those of Group II. In addition, morphine consumption at 4, 8, 12, and 24 hours was significantly lower in Group I.
Conclusion:
Combined with the prevention of central sensitization with ketamine, administration of dexketoprofen prior to incision led to a lower rate of morphine consumption and more effective analgesia than post-incision administration.
