Clinical efficiency of application of improved drain tube insertion in the prevention of greater omentum package in elderly patients with peritoneal dialysis

Abstract

Objective To investigate the effects of improved dialysis catheter in the prevention of omental wrap in patients with postoperative dialysis catheter. Methods A total of 72 patients were divided into experimental group(37 cases)and control group(35 cases). The experimental group was treated by an improved dialysis catheter combined with traditional dialysis catheter.22 patients with a great quantity of greater omentum in experimental group were treated with improved dialysis catheter, namely, tying 3 to 5 knots with 7th line on the large greater omentum to draw the omentum.The control group was treated with traditional dialysis catheter.The routine dialysate measurement, blood routine, serum creatinine, urea nitrogen, C-reactive protein were compared between two groups, and complications such as omental wrapping, perioperative peritonitis, ileus, and peritoneal fluid leakage were observed. Results Compared with the control group, the incidence of greater omental wrap in the experimental group was significantly reduced(P<0.05). No significant differences in other parameters were found, including WBC, hemoglobin, Scr, BUN, hs-CRP, karyocyte count of peritoneal dialysate, over flow discharge of peritoneal dialysis. Conclusions For elderly peritoneal dialysis patients with a great quantity of greater omentum, the improved dialysis catheter can effectively prevent the occurrence of postoperative complication of omental wrapping.And it is simple to operate, which is of great clinical application value.
