Diyaliz Amaçlı Kateter Uygulamalarımız ve Sonuçları

OBJECTIVE: To determine the indications-contraindicationscomplications and the results of temporary and permanent hemodialysis catheters in the patients with chronic renal failure.

MATARIAL and METHOD: 69 of 72 interventions in 36 patients who were admitted to the department of nephrology in our hospital with chronic renal failure requiring haemodialysis and the catheterizations were applied by cardiovascular surgeons were included in the study.

RESULTS: Those results which are such as following: smaller diameter catheters for younger people (<48) (p: 0.007), bigger diameter catheters for older people (p: 0.006); the most frequent reason for withdrawal was dysfunction in younger people, but was the ending of the optimum usage period in the older patients (p: 0.02); the most frequent reason for withdrawal of permanent access was the occlusion with clot (p: 0007); there was not any relationship between the abnormal route and the diameter of the catheter; the most frequent arterial puncture was encountered during the interventions on the right subclavian and left femoral veins (p: 0.01); vagal symptoms could appear during the interventions on the right subclavian artery (p: 0.001); there were statistically different catheter routes; both the infective events and the problems due to occlusion were most frequently encountered in the catheters which the arterial puncture occurred during their insertion (p: 0.002); none of the problem was encountered in the catheters which could be inserted after 5 or more puncture and these catheters were withdrawn since arteriovenous fistulae of these patients became suitable to usage (p: 0.041) were obtained.

DISCUSSION: Both the indications-contraindications-complications and the results of catheterizations for haemodialysis which were applied frequently by cardiovascular surgeons, vascular surgeons, nephrologists and anesthetists and also the differences/features between/of temporary and permanent catheters were determined. We believe that evidences of this study will be helpful for clinicians.
