Background: To investigate the effectiveness of tramadol after tumor surgery.
Aims: The objective of the present study was to compare the analgesic effects of tramadol with morphine.
Methods: The study was performed on randomly selected 20 dogs with tumors that are in different breeds and gender. After induction of anesthesia with propofol, dogs were intubated and anesthesia maintained with sevoflurane. Intravenous fentanyl citrate was used for intraoperative analgesia after stabilization of the anesthesia. When the tumors were surgically removed and operation was completed, dogs were divided into 2 groups in order to given the postoperative analgesic agent. The first 10 dogs to be investigated were identified as morphine group and the second 10 dogs as tramadol group. Post-operative pain scores, heart rates, respiratory rates and body temperatures were recorded at 0, 4, 8, 12, 16, 20, and 24th hours after the operation.
Results: Pain scores were lower in the morphine group than in the tramadol group during all postoperative process.
Conclusion: As a results, it was determined that tramadol has close analgesic effects to the morphine, but morphine provides better analgesia than tramadol.
