| Summary: | 碩士 === 國防醫學院 === 護理研究所 === 94 === Uremic pruritus rate of dialytic patients is still high in Taiwan, roughly lies between 55% and 90%. There are many factors interacted each other to affect their pruritic symptom including the character of demography, trait anxiety, physiologic parameter, disease and dialysis. At present, there are many researches related to uremic pruritus at overseas, but their results are inconsistent. However, there is rare data to show the uremic pruritus of dialytic patients in Taiwan. Therefore, discussing the factors related to uremic pruritus of dialytic patients is one of the important issues.
As a result, the study was a cross-sectional study design. A valid sample of 110 patients were recruited from one of the dialytic room of medical centers in Taipei city. Data were collected by structured questionnaires. The questionnaires used included the character of demography, disease, dialysis, physiologic parameter, trait anxiety and pruritic scale. Data were analyzed by mean, standard deviation, minimal, maximal, frequency, percentile , Chi-Squire test, t test, Mann-Whithey U test, logistic regression and linear regression using SPSS Window 13.0.
Results showed that the pruritic incidence rate of uremic dialytic patients was 70.9%, the patients who received peritoneal dialysis was 72.4% and the patients who received hemodialysis was 67.6%. The mean of pruritic scale was 10.94 points in the itch patients and their mean point in the afternoon more than in the morning. However, the influential factors for pruritic symptom among uremic dialytic patients were the occupation of pre-dialysis, the kinds of renal disease, chloride and skin humidity. And the influential factors for pruritic severity among itch patients were the albumin, chloride and transepidermal water loss.
According to the results of this study, the skin humidity of uremic dialytic patients were related to the pruritic symptom and the transepidermal water loss among the itch patients were related to the severity. Therefore, we will provide patients skin nursing when they seek the intervention for relieving itch. We can teach them use the hydrant skin emollient to improve the dry skin and relieve itch. The finally propose that we want to improve the sleep disorder of the patients and gain the quality of life.
