Catheter malfunction in peritoneal dialysis (PD) patients may lead to technique failure. Surgical repositioning is sometimes required for resumption of PD and is associated with additional costs of procedure and hospitalization. Meanwhile, patients may need hemodialysis via a temporary vascular catheter with increasing costs and risk of catheter-associated bacteremia. We describe an innovative technique of blind bedside PD catheter repositioning as a possible alternative to surgical repositioning when there is catheter malfunction. In 29 patients over a period of 3 years, we attempted blind bedside PD catheter repositioning with immediate successful inflow and outflow in all of them after repositioning. At 1 month, 21 (72.4%) patients had good catheter function and at 6 months, 19 (65.5%) patients were continuing successful PD. This bedside innovative procedure allowed for catheter salvage without constructing a new exit site or tunnel and without the requirement of a break-in period. The benefits to the patient in terms of cost and shortened hospital stay make it ideal for resource-poor settings. We suggest that this innovative technique be attempted before resorting to the open surgical method of PD catheter repositioning.

Hemodialysis patients are at higher risk of cardiovascular disease due to traditional and dialysis-related risk factors. Our aim was to study the effects of hemodialysis on the corrected QT interval (QTc) and QTc dispersion in chronic kidney disease (CKD) without clinically manifest heart disease. Two hundred cases of CKD on chronic intermittent hemodialysis of >3 months' duration were included in the study. Twelve-lead electrocardiography and samples for serum creatinine, potassium, calcium, and magnesium were taken before and after dialysis. The mean age of patients was 52.4 ± 17 years with male-to-female ratio of 3:1. QTc interval and QTc dispersion were prolonged in 47% and 59% before and 50% and 89% of patients after hemodialysis, respectively. The mean values of QTc were 433.4 ± 36.9 ms before and 451.4 ± 39.6 ms after hemodialysis (p = 0.001) and the mean values of QTc dispersion were 60.5 ± 19.3 ms before and 81.5 ± 24.4 ms after hemodialysis (p = 0.001). Similar pattern was observed in all etiological groups of CKD, except for QTc dispersion in malignancy-related CKD (p = 0.216). After hemodialysis, there was a significant fall in the mean values of serum potassium (p = 0.001), rise in serum calcium (p = 0.001), and no change in magnesium (p = 0.424). Patients with post hemodialysis QTc dispersion >74 ms had significantly low mean values of serum potassium and calcium as compared to
