BACKGROUND: Inappropriate use of drugs and their combinations for analgesics has made it difficult to determine the optimal drug combinations for pain mangement.
AIM: To reduce postoperative pain effectively and safely.
MATERIALS AND METHODS: Laparotomy was performed in an adult rat under isoflurane anesthesia. During surgery, the surgical wounds were infiltrated with 50 μL solution containing 0.3% w/v levobupivacaine, 2 mg/mL ibuprofen, and 8 mg/mL epinephrine (treatment group) over the sutured muscle wound before skin closing, and compared to infiltration of that of the normal saline (vehicle group). The 10-fold higher dose of the same combination of medications was injected systemically as a control. Postoperative pain assessed by rodent grimace scales scoring. One-way ANOVA following Dunnett multiple comparisons test was used at 95% of confidence level.
RESULTS: There was decreased pain for the treatment group (p = 0.025, q = 4.527) and the control group (p = 0.031, q = 4.178) only 24 h after the end of the successful infiltration. The rodent GS scale scoring showed the fall in pain was started within three hours post-surgery in the treatment group. There was decreased pain in the treatment group (p = 0.048, q = 3.527) and the control group (p = 0.043, q = 3.891) only as compared to vehicle group 24 h after the end of the successful infiltration.
CONCLUSION: The infiltration of the surgical wound with levobupivacaine, ibuprofen, and epinephrine combination was effective in the healing of wounds after laparotomy.
AIM: To reduce postoperative pain effectively and safely.
