Clinical application of right low-position modified peritoneal dialysis catheterization

Abstract

The aim of this study was to investigate peritoneal dialysis catheter malposition following low-position modified peritoneal dialysis catheterization and its clinical application value. A total of 48 patients receiving traditional peritoneal dialysis catheterization (the traditional group) and 95 patients receiving right low-position modified peritoneal dialysis catheterization (the modified group) from 2006 to 2011 were selected. The inflow time, outflow time, ultrafiltration volume of peritoneal dialysis solution and rate of peritoneal dialysis catheter malposition in the two groups of patients following surgery were compared and analyzed. There were no significant differences of inflow time, outflow time and ultrafiltration volume of the peritoneal dialysis solution between the two groups. In the modified group, no post-operative peritoneal dialysis catheter malposition occurred, therefore the incidence rate was 0. However, 9 patients in the traditional group presented peritoneal dialysis catheter malposition, an incidence rate of 18.75% (9/48). Among them, 6 patients required a second surgery. There was a statistically significant difference in the incidence rate of catheter malposition between the two groups (P<0.01). Right low-position modified peritoneal dialysis catheterization significantly reduced the incidence rate of peritoneal dialysis catheter malposition following peritoneal dialysis, and was shown to be significantly more effective than the traditional peritoneal dialysis catheterization and is therefore worth promoting for clinical use.
