HOW FREQUENT ARE CARDIAC ARRYTHMIAS AFTER CENTRAL VENOUS CATHETERIZATION IN PATIENTS ADMITTED IN INTENSIVE CARE UNIT?

ADr. Muhammad Bilal Anwar, Dr. Ehsan Ul Haq, Dr. Rabia Saleem

Objective: In critically ill patients’ central venous catheterization is commonly practiced. The aim of this study is to estimate the risk of cardiac arrhythmias associated with CVC (central venous catheterization). Methods: Total 100 patients were included in study who underwent central venous catheterization. 3ml blood was collected from all patients for study of serum sodium, potassium, creatinine and blood urea nitrogen level. Electrocardiography (ECG) was done during and after the procedure. Vitals were monitored before and after catheterization. Results: The rate of arrhythmias as studied by ECG was; 3 AF, 6 VT, 6 PAC and 6 PVC. Previous catheterization, sex and serum electrolytes levels had significant association with the rate of arrythmias in patients. Conclusion: Although central venous catheterization is a small operative procedure but due to its association with cardiac arrhythmias, it must be performed in ICU with proper arrangements to overcome arrhythmias, if occur. Vitals monitoring should also be done before, during and after the procedure. Key Words: arrhythmia, central venous catheterization, Electrocardiography.
