About

This is randomised double blinded placebo-controlled parallel-group study. Patients in Hospital Queen Elizabeth, Sabah and Hospital Universiti Sains Malaysia, Kelantan who undergo laparotomy for peritonitis will be equally randomised into two groups : intervention group receiving super-oxidised solution and the control group receiving normal saline during peritoneal and wound lavage.

This is a superiority study assessing the effectiveness of the intervention. The patient and doctors directly involved in the partient care will be blinded in this study

Full description

OBJECTIVES

PrimaryOutcome:

To evaluate the effectiveness of peritoneal lavage with superoxidised solution in reducing incidence of surgical site infection after open surgery for peritonitis.

SecondaryOutcome:

i.To evaluate the effectiveness of peritoneal lavage with super-oxidised solution in reducing inflammatory markers C-reactive protein(CRP) at 24 and 48 hours after open surgery for peritonitis ii.To evaluate the effectiveness of peritoneal lavage with super oxidised solution in reducing duration of post-operative ileus after open surgery for peritonitis.

METHODOLOGY

Study Design This is a randomised double blind placebo controlled parallel group study. This is a superiority study assessing the effectiveness of the intervention. The patients and doctors directly involved in the patient care will be blinded in this study.

Masking Study participants were randomly assigned following computerized block randomization using the website www.randomization.com with a block size of 8 and allocation ratio of 1:1. Allocation sequence and concealment will be performed by the research staff from the Clinical Research Centre who had no clinical involvement in the trial. The allocation sequence will be concealed from the researcher enrolling and assessing the participants in sequentially numbered, opaque, sealed envelopes.

The study participants, healthcare providers who attend to the participants during the trial (surgeon and nurses), outcome evaluators (surgical doctors and nurses) and data collectors will be blinded to the allocation.
