Dialysis Solution Analysis forPeritonitis Infection Prevention by usingOptical System Prototype

Abstract

Continuous Ambulatory Peritoneal Dialysis CAPD peritonitis usually occurs due to contamination by bacteria from the skin or the environment of the inserted catheter,peritonitis infection isan important cause of CAPD failure and patients switching to another treatment, it has many signs the predominant one is a cloudy bag, this research used the cloudy bag sign to detect the infection inan early stage. The aim of this study was to analyze dialysis solution for peritonitis infection prevention by designing a simple prototype to detect the turbid solution by using Scattering Light Theory.This study was applied on 14 patients (male and female) with different ages. Two samples were taken from the patients one was reading at the same time,the second was sub culturing by standard bacteriato simulate the peritonitis infection proportion to the difficulty of finding peritonitis infection samples. 180 known samples were detected by the prototype 90 samples with bacteria and 90 without bacteria to determine the range of normal and abnormal. The inverse relationship where the greater dispersion of light (increased turbidity) the less resistance valuein the examined samples .The classification function was produced and gave result with the normal and infected sample with accuracy equal to (70.9%). The prototype reading was compared with laboratory turbidimeter on National Public Health Laboratory (STAC) and gave satisfied results.Optical system is a simple way for turbidity detection, help old and new patient to detect the peritonitis infection in an early stage.
