Therefore, the routine use of chest radiographs to establish the correct placement of CVC is recommended. Each lumen is used for different functions usually inflation of the balloon. The malpositioning of the catheter tip may occur at the time of the insertion or later on as a result of spontaneous migration due to anatomic positioning or pressure changes within the thoracic cavity. The most common type is the Foley catheter, which may have two or three lumens. Occasionally, despite the proper technique, the tip of the catheter may not terminate at the desired level. However, the ability to aspirate blood freely from the catheter lumen after the placement of the catheter does not necessarily confirm a proper placement of the catheter tip. Also, the venous blood was aspirated freely through each lumen of the CVC. In our case, the resistance was encountered during the insertion of the guidewire, and the resistance soon disappeared and the guidewire was advanced further without any other resistance. from publication: Developing a System for Integrated Automated Control of Multiple Infusion Pumps: The. The difficulty in inserting or advancing the guidewire should have created an index of suspicion for misplacement of the CVC. Download scientific diagram Cross-sections of a single, dual and a triple-lumen catheter. The inaccurate CVP measurements or inability to obtain an ideal wave from tracing are suggestive of an incorrect location of the catheter tip. The correct placement of the CVC is important in obtaining the accurate central venous pressure (CVP) measurements and hemodynamic management. We present a case of malpositioning of a CVC into a jugular venous arch (JVA), which was accidently found in the process of sternotomy during coronary artery bypass graft (CABG) surgery. The CVC positioned incorrectly, whether inside of a vessel other than the SVC or impinging on the wall of the SVC, may cause serious complications. The misplacement of the CVC inserted via the subclavian, internal jugular, or other veins is not unusual and is the cause of relatively common complications. The optimal location of a central venous catheter (CVC) is within the long axis of the superior vena cava (SVC) outside of the right atrium. The most common routes of insertion include the internal jugular, external jugular, subclavian, basilic, and femoral veins via a percutaneous approach. The central venous catheterization is a simple, relatively inexpensive method of assessing a patient's circulating blood volume, cardiac status, and vasomotor tone, and it is an essential component of modern-day critical care.
