Abstract
BACKGROUND
Despite its advantages, laparoscopic surgery causes significant shoulder and abdominal pain in 35%-80% of patients. The cause of post-laparoscopy pain is not fully understood, but it is assumed to be a multifactorial referred pain.
AIM OF THE STUDY
To evaluate the effect of different analgesia techniques on post-laparoscopic pain and inflammatory markers.
METHODS
Patients scheduled for elective laparoscopic cholecystectomy were randomly assigned to receive local hepatic and right subdiaphragmatic infiltration of one of the 4 study drug combinations: Group 1 (G1) received 20 ml bupivacaine 0.25%; Group 2 (G2) received 20 ml bupivacaine 0.25% +3 mg morphine sulphate; Group 3 (G3) received 20 ml bupivacaine 0.25% + 3 mg morphine sulphate +200 µg/kg ketamine; and Group 4 (G4) received 20 ml isotonic saline as the control group.
RESULTS
In G3, both shoulder pain on the verbal numerical rating scale and inflammatory marker levels were lower compared with the other groups. The highest levels of inflammatory markers were observed in the control group; this difference was statistically significant. No side effects or complications were observed in the study groups.
CONCLUSION
The addition of ketamine and morphine to bupivacaine for hepatic and subdiaphragmatic infiltration produced good analgesia and reduced inflammatory marker levels after laparoscopic cholecystectomy.
