Estudio retrospectivo de las complicaciones de los catéteres temporales para hemodiálisis

the aim of this study was to analyze the duration and causes of removing complications for temporary catheters for haemodialysis. we studied 1409 catheters which were implanted on 608 patients in haemodialysis chronic (60.9 ± 15.5 years, 341 females (56%) and 267 males (44%). 280 (46%) patients received 1 catheter and 144 (24%) 2 catheters. we analyzed 546 catheters retired exclusively by complications. mean duration of the catheters (n=546) of was 21±36 days. the main catheters complications that forced their retreat were: 75% for deficit blood flow rate, 11% infection, 6%, for loss of surgical suture, 3% for occlusion, 3% for elbowed. the deficit blood flow rate appeared to the 18 ± 34 days and the la infection to the 29±50 days. mean duration of the catheters was of the 16±32 days for the left side and 23±38 for right side (p<0.0001). when we compared the different blood vessel, mean duration of the catheters was of the 25.3±43 days for the jugular, 17.5±23 for the subclavia, and 11.9±10 days for the femoral, being significant differences among jugular-subclavia and femoral vein (p<0.05). when comparing the duration, among a single lumen vs dual lumen, in catheters retired by complications, they were not significant differences (multivariate analysis). we can conclude that the duration, of the catheters placed in jugular or subclavia veins and right side is superior to the placed in femoral vein or left side, being recommended its use therefore as temporary access in hd, also facilitating the patient's mobility and ambulatory dialysis. we have not found, at least in our study, differs in the duration among the single lumen versus dual lumen catheters.
