Introduction

Intra-abdominal adhesions are fibrous bands that often develop following abdominal surgery or inflammation, posing significant risks of morbidity and mortality. As the number of surgeries increases globally, the quest for effective methods to prevent these adhesions has become a priority in surgical practice. This study aimed to assess the efficacy of different irrigation solutions, specifically bupivacaine, saline, and two doses of lidocaine, in reducing intra-abdominal adhesions in a rat model after undergoing laparotomy.

Efficacy of Local Anesthetics in Reducing Adhesions

The research demonstrated that the quantity and quality of adhesions were notably higher in the control group versus those treated with lidocaine at a dose of 6 mg/kg and bupivacaine. Specifically, the application of lidocaine in higher doses significantly reduced adhesion formation compared to the control and saline groups. The findings indicate that while both lidocaine (6 mg/kg) and bupivacaine irrigation effectively minimized the formation and severity of adhesions, lidocaine showed superior outcomes at higher doses, thus underscoring the importance of dosage in achieving effective results.

Conclusion

In conclusion, the study suggests that the application of lidocaine (6 mg/kg) and bupivacaine during peritoneal lavage can significantly mitigate the risks associated with abdominal adhesions, enhancing surgical outcomes. Although the approach does not entirely prevent adhesion formation, it effectively reduces their severity and quality, pointing to local anesthetics as promising agents in adhesion prevention strategies. However, further studies are necessary to validate these results in larger populations and to explore potential systemic effects and long-term outcomes in clinical settings.
