Factors influencing function of temporary dialysis catheters.

Journal Article

AIM: To determine risk factors for failure of temporary dialysis catheters, we prospectively studied the outcome of 178 non-tunneled dual lumen catheters placed in 126 consecutive patients requiring treatment of acute renal failure (ARF) or end-stage renal disease (ESRD). METHODS: Internal jugular (IJ) or subclavian (SC) catheters were used in 122 instances and femoral catheters were employed in 56. RESULTS: IJ or SC catheters with tips in the right atrium or superior vena cava (n = 112) failed (defined as a blood flow < 250 ml/min) 17% of the time, compared with a 40% failure rate for catheters with more peripherally located tips (n = 10), p < 0.05, chi2 testing. In a multivariate analysis, use in ESRD and location peripheral to the SVC were risk factors for catheter failure. Use of one of three catheter brands was associated with a lower failure rate. Although mean venous pressures at 200 ml/min blood flow were higher in IJ or SC catheters that failed, the presence of a high venous pressure, number of catheter uses, IJ vs. SC placement, inpatient vs. outpatient status, and fresh venipuncture vs. placement over a guidewire passed through a previous catheter did not predict catheter malfunction. With femoral catheters, the only risk factor for failure was use in ESRD. CONCLUSION: Of the factors that can be influenced by placement technique, catheter tip location is most important. Whether one catheter brand is superior awaits further confirmation.
