Effects of the intra-abdominal place of the peritoneal dialysis tube in B ultrasound detection on complications

Objective To study the influence of distance on complications in catheter placement by measuring the distance between the end of the intra-abdominal part of the peritoneal dialysis tube and the bottom of pouch of Douglas under the guidance of B ultrasonography.Methods We selected 137 patients who had peritoneal dialysis catheterization in our department from June 2014 to December 2016 as our research subjects. And they ranged in age from 19-74 years. Because of the anatomical differences, the patients were divided into two groups by gender (76 males and 61 females). In one week after catheterization, detection was made under the guidance of B ultrasonography. The male and female patients were divided into three subgroups according to the distance——subgroup 1 (0-3 cm), subgroup 2 (3-5 cm), and subgroup 3 (>5 cm). During the follow-up period of 3 months, abdominal pain, bleeding, irrigation and drainage, etc., were observed. The data were processed by the statistical software SPSS 13.0. The differences were compared between two gender groups or among three subgroups.Results The difference was significant in the prevalence of catheterization complications among the three subgroups regardless of gender (P<0.05). When the distance was 3-5 cm, the prevalence was the lowest. When the distance was 0-3 cm, patients were more likely to have abdominal pain at a serious level. When the distance >5 cm, patients were more likely to have complications of tube floating and tube plugging.Conclusions When the distance is 3-5 cm, the prevalence of the complications mentioned above is the lowest regardless of gender. This prompted that when placing the peritoneal dialysis catheter into the abdomen, doctors must choose the right incision and the ideal length of the peritoneal dialysis tube in abdomen depending on the size of the patients, to decrease the prevalence of complications and consistently improve the quality of peritoneal dialysis.
