Abstract
Rrenal failure (CRF) is a condition in which the kidneys are incapable of performing their normal functions. The important treatment option for persons with end stage renal diseases is hemodialysis. Infection is the most common and serious complication of hemodialysis vascular access. Vascular access infection in hemodialysis patients causes significant mortality and morbidity (Moore, 2012). A-The aims of this study were: 1- To assess the effect of applications of aloe vera on the occurrence of bacterial infection in central venous catheter in hemodialysis children. 2- To assess the effect of applications of povidone iodine on the occurrence of bacterial infection at central venous catheter in hemodialysis children. 3- To compare between the effect of application aloe vera and povidone iodine on the occurrence of central venous catheter bacterial infection in hemodialysis children. B- Research hypothesis: Application of aloe vera gel will reduce the occurrence of bacterial infection in hemodialysis central venous catheter. C-Settings: The study was conducted at pediatric hemodialysis units in Menofia University Hospital and Health insurance Hospital for School Students.D-Sample:- A sample of 60 children undergoing hemodialysis with temporary vascular access was selected from the previously mentioned settings. A simple random sample was used to assign them into two equal groups (control group and experimental group). E-Tools of the study: Three tools were utilized for data collection: Tool one: - patient’s profile structured interview questionnaire sheet. These parts were socio-demographic data, Clinical data and patient’s care questionnaire. Tool two: Observational checklist. It included three parts. These parts were general manifestations of infection, Local manifestations of infection and Word-Graphic Rating Scale (WGRS). Tool three: - microbiological studies. F-The main results of the study showed that: • Means and stander deviations of the ages of children in the control and experimental groups were 12.1±3.03 and12.83±2.48 respectively. Males were more than females in the experimental and controls groups (63.3% vs.36.7% and 53.3% vs. 46.7) respectively. • The most common sites of hemodialysis central venous catheterization were the subclavien vein (86.7% and 80.0%) for the experimental and control groups respectively. • More than half of children performed bathing twice weekly (60.0% experimental and 56.7% control groups).
