Evaluación del dolor en la punción de una fístula arteriovenosa para hemodiálisis comparando pomada anestésica frente a frío local

Abstract

Pain in hemodialysis patients is not valued in its entirety and does not take into account the limitations resulting in the quality of life of these patients. We performed an observational study, which analyzed the degree of pain, that suffers a patient undergoing hemodialysis, when is punctured his arteriovenous fistule. To do this we compare the pain that occurred before the puncture if we used one of three methods: anaesthetic cream (Emla ®), PLACEBO (moisturizer) and ICE. We also assessed whether a method interferes dialysis parameters during the session. We studied 28 patients (23 men and 5 women) carrying fistula. The variables measured were pain (VAS), blood flow, blood pressure, venous pressure and clotting time. These variables were collected during the three-week duration of the study (36 sessions of hemodialysis) graphs. 36 were analyzed hemodialysis sessions using a graph on one hand we observed that the used method is statistically significant (p- value, p = 0.004), on the other hand, no significant differences between the used method and the remaining parameters contained in the hemodialysis session (p=0.194, p=0.278, p=0.902, p=0.445). With regard to the used method patients chose as best method Emla ® with 67.86%. According to the data we can conclude that there are no statistical differences in the studied variables. Emla ® using gets better result in terms of pain, but does not change any other parameters like the other two methods.
