Abstract: Introduction: Localization of Control Venous Catheter (CVC) is essential in emergency (ER) and ICU settings; accurately confirming of the location of CVC may enable clinician to minimize the risk of the procedure. Radiography and Sonography are two common procedures, which is used for localization of CVC. Due to volatile hemodynamic nature of patients, it is vital to follow CVC procedure and diagnose possible side effects and complications as soon as possible. Aim of current study is to assess efficacy, practicality and procedure time-curve between two aforementioned methods (Sonography Versus Radiography). After CV line preparation. Methodology: In current cross-sectional study we obtained 201 participants via convenient sampling method from Rasoul-E-Akram Hospital, Haftom-E-Tir Hospital and Firoozgar hospital. Participants were chosen from patients older than 18, who were admitted to ER or ICU in aforementioned hospitals and were candidate for CV line preparation. Following CVC procedure, physicians proceeded with radiography and sonography among all patients and compared approaches with respect to, timing, confirmation of catheter location and post CVC complications. Results: The average time of sonography procedure was estimated roughly 2.08 minutes, in which the maximum time was 5.5 minutes and the minimum time was 1.04 minutes. The standard deviation suggested that the sonography time for most of patients was about 2 minutes. Variance of sonography time among the above population was not reported. The data analysis showed that Chest X-Ray (CXR) time average for studied patients was about 40.82 minutes, in which the minimum time was 10 minutes and the maximum time was 150.15 minutes. The standard deviation of this variable suggested that variance level and CXR time difference among aforementioned patients were high (about 28.2). Bubble was found in the sonography of 199 cases and just two cases were excluded. According to these results, sensitivity of sonography was 99%, specificity was 100% and Kappa coefficient between sonography and radiography was 98%. Conclusion: All in all, with respect to high correlation in accurate localization of CVC in both approaches (radiography and sonography) plus competitive advantage of sonography over radiography by maintaining shorter time in confirmation of CVC location, sonography can be discussed as optimum and routine modality with respect catheter location confirmation in emergency settings.
