Baby oil therapy for uremic pruritus in haemodialysis patients.

AIMS

The purpose of this study was to investigate the effectiveness of chilled/un-chilled baby oil therapy for treating uremic pruritus in haemodialysis patients.

BACKGROUND

Uremic pruritus affects 50-90% of haemodialysis patients, which makes it one of the most common medical problems in this population. Pruritus can cause skin infection, desquamation, pathological skin change, sleep disorder, anxiety, depression and social dysfunction.

DESIGN

A prospective, pretest-post-test quasi-experimental design was used.

METHODS

Haemodialysis patients with uremic pruritus were recruited and randomly assigned to one of three groups: experimental group 1 (chilled baby oil treatment; n = 30), experimental group 2 (un-chilled baby oil treatment; n = 31) and a control group (routine care only; n = 32). Participants in experimental group 1 and experimental group 2 were treated with chilled and un-chilled baby oil, respectively, for 15 minutes at least once daily for three weeks. The control group received no intervention other than standard care. Data collection included demographic data and itch severity. Medical records were also reviewed.

RESULTS

The baseline characteristics of subjects in this study were as follows: 59% were male, mean age was 61·88 (SD 12·7) years, mean duration of haemodialysis was 5·31 years, mean duration of uremic pruritus was 40·58 (SD 37·8) months and mean intensity of uremic pruritus was mild. The anti-pruritic effects were significantly larger in subjects treated with either chilled or un-chilled baby oil than in those who received routine care. Anti-pruritic effects did not significantly differ between experimental group 1 and experimental group 2.

CONCLUSIONS

The study confirmed that, for relieving pruritus in haemodialysis patients, either chilled or un-chilled baby oil is as effective as moisturising lotions and cooling soothing agents.

RELEVANCE TO CLINICAL PRACTICE

Applying baby oil is a simple, safe, inexpensive and easily administered treatment for itchy skin in haemodialysis patients. By preventing or reducing uremic pruritus, baby oil treatment may also improve quality of life in this patient group.
