Exit-Site Relocation: A Novel, Straightforward Technique for Exit-Site Infections.

Background:Exit-site infection (ESI) and tunnel infection (TI) of the peritoneal dialysis (PD) catheter are significant causes of catheter or even method loss as well as patient morbidity. Among the methods that have been in use thus far, the removal and replacement of the catheter often needs to be followed by switching temporarily to hemodialysis, whereas catheter splicing or unroofing of the tunnel tract and shaving/removal of the superficial catheter cuff have not gained universal acceptance thus far.Methods:We treat chronic ESI with exit-site relocation under local anesthetic with removal of the external cuff. For the purposes of this study, we conducted a retrospective cohort analysis of all exit-site relocations performed using that technique over a 5-year period.Results:Twenty-seven patients (16 male, mean age 58 years, range 23 - 81 years) with chronic ESI underwent exit-site relocation under local anesthetic as a day-case procedure. Follow-up was 47.5 ± 22.4 months (range 10.8 - 79.4 months). No dialysate leaks occurred following the procedure. Peritoneal dialysis was resumed immediately. The procedure resulted in long-term resolution of the infection in 20 of the 27 patients (74%). In 7 patients (26%), the catheter had to be removed eventually, either because of ESI recurrence (5 patients) or TI (2 patients), which in 2 cases was subsequently complicated by PD peritonitis, and the patients were switched to hemodialysis.Conclusion:The technique described herein is a safe, straightforward, and effective method for the treatment of chronic ESI while the patient remains on PD and avoids switching to hemodialysis.

Psychological intervention in fluid management.

BACKGROUND: Hemodialysis is a palliative treatment for patients with established renal failure (ERF), and volume overload is a common problem for hemodialysis patients with low urinary output. Volume overload is thought to be mostly attributable to interdialytic fluid intake by the patient and is associated with an increased symptom burden and the development of serious medical complications. Repeated episodes of volume overload may adversely affect staff-patient relationships and the perception of care in this patient population. The aim of this case series study was to evaluate the effect and experience of a psychological intervention on interdialytic weight gain in a small group of patients. METHODS: Five patients were treated. The intervention involved using techniques derived from both cognitive behavior therapy and motivational interviewing. The main outcome measures were interdialytic weight gain and patient perception of the intervention. RESULTS: Three of the five patients reduced both mean interdialytic weight gain and the frequency with which they gained in excess of 3% of their dry weight during the intervention phase. The intervention was found to be acceptable to patients. SIGNIFICANCE OF RESULTS: The intervention was effective in helping three of the five patients to reduce both the frequency and the severity of volume overload, and two of these patients maintained this for at least 6 months post intervention. The intervention used actively engaged the patients and appeared to be experienced positively. The methods used to mobilize patient resources and optimize staff-patient relationships as vehicles of change are discussed. Both may have implications for treatment concordance and the perception of care delivered.
