Occupancy of vascular accesses and factors affecting that time in hemodialysis patients with chronic renal failure

There need to be a suitable vascular access for the patients to provide efficient HD treatment. With is aim, AVF, AVG, temporary and permanent catheters are being used. There are many factors which effect the utilization of vascular accesses; the most important one of these factors is the developing complications which are associated with morbidity and mortality for the HD patients significantly. This research has been designed descriptive and retrospective qualification with aim of examining the patency of vascular accesses in the patients who have Cronic Renal Failure and the factors effecting this duration. Research has been performed in four separate and private dialysis centers with their permission by collecting data for a period of three months. According to the information received from the universe of Bursa provincial health directorate, it has been determined as 1976 patients. The study has been created from 300 patients with the method of determining the volume of the sample. Questionnaire has been used as data collection tool. Analysis of the data which has been obtained has been performed by using Mann-Whitney U-test and Chi-square tests in computing environment. As a result of there search, it has been found out that the majority of the patients are male (54.7 %), their medial age is 58.96±13.59 (23-87) and the reasons of CRF are generally because of Diabetes Mellitus (DM). While it has been found out that 78.7 % of the patients have begun HD treatment with temporary catheter and %18.3 of them have begun with AVF for the first time, it has been determined that mostly, AVF (91.3 %) is actively used as vascular access. The average utilization durations of the vascular access species have been determined as 38.16±57.16 (1-300) months for AVF, 22.22±23.12 (1-72) months for AVG, 173.66±101.36 (24-365) days for permanent catheter and 37.25±19.46 (11-150) days for temporary catheter. It has been found out that the most commonly occuring complication is thrombosis in AVF/AVG (39.13 %); localized exit site infection in temporary and permanent catheters (41.75 %) and thrombosis is effective for the utilization of AVG (p<0.001). It has been seen that the technique of rope ladder has been implemented in proportion of 66.4 % as a technique of needle entry for the patients, more problems have been found out in vascular accesses of the patients implemented the puncture technique (p<0.001) and anevrizma/psödoanevrizma has occured much more. (p<0.001). Key Words: Hemodialysis, vascular access, chronic renal failure (CRF)
