Objective To design the protection of peritoneal dialysis catheter and solve the problem of broken peritoneal dialysis catheter during clinical use. Methods A total of 94 patients with end-stage renal disease who received newly opened peritoneal dialysis in the Department of Nephrology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2016 to December 2017 were selected as research objects. In order of the time of tube opening, 47 patients with singular ordinal number receiving treatment were set as the control group, and 47 patients with even ordinal number receiving treatment were set as the observation group. The patients of control group, using the traditional peritoneal dialysis tube nursing; the patients of observation group, using anti- broken peritoneal dialysis tube for nursing. To observe and compare the incidence of dialysis catheter loosening and breakage during dialysis in the 2 groups of peritoneal dialysis patients, as well as the patient satisfaction. Results The catheter crease deformation of the observation group(0 case) was significantly lower than that of the control group (12 cases), and the difference was statistically significant (χ2=13.610, P<0.05). The total satisfaction of patients in the observation group was 97.87％ (46/47), while that of patients in the control group was 72.34％ (30/47). The total satisfaction rate of observation group was significantly higher than that of control group (χ2=12.086, P<0.01). No leakage occurred in the observation group, which was also significantly lower than that in the control group. However, due to the limited observation time, the number of cases was small without statistical significance (P>0.05). Conclusions The improved peritoneal dialysis catheter is more convenient, safe and effective for long-term peritoneal dialysis patients, and it can reduce the incidence of peritonitis associated with peritoneal dialysis catheter, which is worthy of clinical application.
