Application of improved fixation during peritoneal dialysis catheterization

Objective To observe the application of improved fixation of peritoneal dialysis(PD) during PD catheterization.Methods From June 2014 to June 2019,a total of 120 end-stage renal disease patients on PD aged above 18 years were randomly divided into two groups of traditional and improved abdominal wall fixation(n=60 each).During a follow-up period of 6 months,catheter related complications were compared.Results No inter-group differences existed in gender,age,height,weight,body mass index,surface area,creatinine/urea level,glomerular filtration rate or albumin/hemoglobin level.None of them had an onset of abdominal visceral injury,bloody ascites,fluid leakage,surgical incision infection or poor healing.No inter-group differences existed in operative duration,incidence of peritonitis or hernia(P>0.05).The rates of catheter drift and greater omentum packaging were high in traditional group than those in abdominal wall fixation group(P<0.05).Conclusion Improved PD fixation may reduce the odds of PD catheter malfunction.
