Clinical Trial Summary

This study is to evaluate the effectiveness of peritoneal lavage with super-oxidised solution in reducing surgical site infection after open surgery for perforated appendicitis.

Description:

Open appendicectomy for perforated appendicitis is associated with significant morbidity from surgical site infection. The standard practice is to perform peritoneal and wound lavage using normal saline solution. The investigators propose the use of superoxidized solution for peritoneal and wound lavage to decrease the incidence of surgical site infection.

Superoxidized solutions contain hypochlorous acid (HOCl) which has bactericidal properties. The reactive oxygen species that is produces damages cell wall membrane of unicellular organisms, however remains safe when in contact with human or animal tissue. It is commonly used for topical treatment of wounds.

• Infections
• Perforated Appendicitis
• Surgical Wound Infection

Intervention

Drug:
• Superoxidized Water
Super-oxidized solution contains hypochlorous acid (HOCl) which exhibits bactericidal activity. These reactive species create an imbalanced osmotic gradient which damages the cell membrane integrity of single celled organisms, and subsequently denaturing its lipid and protein content. Multicellular organisms including host tissue are not susceptible to such changes in osmolarity hence spared from damage.
• Normal Saline
Normal saline contains 0.9% sodium chloride.
