Abstract: 【Abstract】Objectives To observe the incidence and related influencing factors of arrhythmias during internal jugular vein catheterization in hemodialysis patients . Methods 100 cases underwent internal jugular central venus catheterization in our hospital from January 2010 to June 2012 were selected . Arrhythmias was recorded by the application of ECG monitor in the puncture process . The correlative data of patients , such as general information of patients、blood gas analysis、electrolytes、 renal function 、the effect of local anesthesia 、the succese rate of puncture and the length of insert guide wire ，were collected and analysed the relationship with arrhythmias . Results 29 cases of arrhythmia in the puncture process related with the length of insert guide wires (p <0.05), unrelated with age、 height、the effect of local anesthetic、 the succese rate of puncture、 electrolyte、PH value、PO2 and SPO2. The express of arrhythmias is atrial and ventricular premature beats, atrial premature beat mainly. Conclusions The incidence of arrhythmias during internal jugular vein catheterization in hemodialysis patients is more and related with the insertion of guide wires too deep , which to avoid over-insert the guide wire can reduce the incidence of arrhythmias.
