| Abstract

|
Proper placement of central venous catheter tip could reduce early and late catheter related complications. Although the live fluoroscopy is standard of care for placement of catheter, it is not available in many centers. Therefore the present study evaluated the sensitivity and specificity of bed side chest x- ray (CXR) for proper positioning of catheter tip. 82 adult patients undergoing elective placement of tunneled central venous catheter (CVC) were enrolled in this study during 2010-2012. The catheter tip position was evaluated by post operative bed side chest radiographs as well as trans-thoracic echocardiogram as definite diagnostic tool. The catheter position was considered correct, if the tip was positioned in the right atrium both in CXR or echocardiography. Finally CXRs interpreted by expert radiologist, thus findings were compared by echocardiography. Sensitivity, specificity, accuracy, positive, and negative predictive values were calculated. Data were analyzed by SPSS ver 16, and p values less than 0.05 considered significant. The patients were 57.37 +- 18.91 years of age, weighed 65.79 +- 15.58 kg and were 166.36 +- 9.91 cm tall. Sensitivity and specificity of CXR for proper catheter tip position were 74.3 percent, and 58.3 percent respectively. Positive and negative predictive values were 91.2 percent and 28 percent. In addition accuracy, positive likelihood ratio, and negative likelihood ratio were 71.9 percent, 1.78, and 2.27 respectively. Bedside CXR alone does not reliably predict malpositioning after CVC placement.
