RESUMEN
Prospectively from January 1991 to January 1993, the efficacy and complications of 104 polyurethane, double-lumen femoral vein catheterizations (FVC) in 96 renal failure patients were studied. Ambulation was allowed in the hospital as well as at home while the catheter was in. There were 53 males and 43 females, with ages ranging from 13 to 87 (mean, 48.3 +/- 19.7) years. Forty-eight patients had chronic renal failure and 48 had acute renal failure. The catheters were used for 1 to 26 days (mean, 8 +/- 5 days). Fifty-two (50%) of the FVC were used for 2 weeks and 14 (13.5%) for 3 weeks or longer. The various complications encountered were infection (n=31), poor blood flow (n=8), displaced catheter (n=6), thrombosis of the catheter (n=4), hematoma (n=4), bleeding (n=3), exit site infection (n=3), ileofemoral vein thrombosis (n=2), and tear in the catheter wall (n=2). On removal, bacterial colonization was present in 34 out of 93 catheter tips (36.5%); Staphylococcus epidermidis (n=12) was the commonest organism grown. There was no significant difference of infection between diabetic and nondiabetic chronic renal failure patients. The duration of catheterization was found to have no relation with either thrombosis or infection. Femoral vein catheters can be used for hemodialysis for 2 to 3 weeks and ambulation during cannulation may be allowed.
