Abstract

Purpose: To evaluate the effects of metoclopramide on abdominal wall healing in rats in the presence of sepsis.

Methods: 40 rats divided into two groups of twenty animals, subdivided into two subgroups of 10 animals each: group (E) - treated with metoclopramide, and saline-treated control group. The two groups were divided into subgroups of 10 to be killed on the 3rd day (n = 10) or day 7 (n = 10) after surgery. Sepsis was induced by cecal ligation and puncture. We performed also the section and anastomosis in left colon. The synthesis of the abdominal wall was made with 3-0 silk thread. We measured the breaking strength of the abdominal wall and made the histopathological evaluation.

Results: on 3rd day postoperative, the average breaking strength in the E group was 0.83 ± 0.66 and in group C was 0.35 ± 0.46 (p = 0.010). On the seventh day, the breaking strength in group E was 11.44 ± 5.07, in group C 11.66 ± 7.38 (p = 1.000). The E7 group showed lower inflammatory infiltration, foreign body reaction, fibrin than control.

Conclusion: animals treated with metoclopramide had a higher resistance of the abdominal wall on the 3rd postoperative day.
