The Numbness Effect of EMLA Cream on Hemodynamic Changes During Fistula Cannulation in Patients Undergoing Hemodialysis

Abstract

Background and Aims Patients undergoing hemodialysis report the pain of repeated insertion of vascular needles as the most stressful condition in the treatment process and the greatest concern in their lives. This pain can cause hemodynamic changes before the hemodialysis process. This study was conducted to determine the numbness effect of EMLA cream on hemodynamic changes during fistula cannulation in patients under dialysis. Methods This study is a clinical trial conducted on 50 patients undergoing dialysis in Khorramabad Shohada Hospital in 2013. The patients were randomly divided into two groups (spelling) and (placebo) after entering the study. Hemodynamic changes were measured in two groups before and after fistula cannulation. In order to analyze the data, SPSS version 19 was used. Results There was no significant difference between two groups in terms of demographic variables and duration of using fistula (P>0.05). The hemodynamic parameters (systolic, diastolic blood pressure and pulse rates) were not significantly different between groups before cannulation (P>0.05). The systolic blood pressure and pulse rate in the placebo group were significantly higher than the EMLA group after fistula cannulation (P<0.001). Conclusion Application of EMLA cream as an easy method reduces pain during fistula cannulation in patients under hemodialysis and provides hemodynamic stability at the onset of hemodialysis.
