Factors Associated with Pain during Vascular Access Intervention Therapy

ObjectiveThe objective of this study is to investigate and compare factors associated with pain during vascular access intervention therapy.Subjects and methodsFifty patients provided informed consent to participate in a survey of pain by questionnaire after receiving dialysis treatment at our hospital. Balloons for use during the procedure were chosen at random in this prospective randomized control study. A numeric rating scale (NRS) was used for pain assessment.ResultsA semi-compliant balloon caused significantly worse pain as compared with the other types of balloons (NRS, 7.67 ± 1.57 vs. 6.02 ± 1.89; p<0.05). There was no correlation between maximum inflation pressure and pain, or between age and pain, and no difference between diabetic and non-diabetic patients. A comparison among vascular dilation locations, as well as a comparison of AVF with AVG also revealed no significant differences.ConclusionsThe reason for severe pain with use of the semi-compliant balloon as compared with the other types mi...
