Transoesophageal echocardiography and central line insertion

Area of Science:

• Cardiology
• Anesthesiology
• Medical Imaging

Background:

• Central venous catheter (CVC) insertion is a common procedure in cardiac surgery.
• Potential complications can arise during CVC insertion.
• Transoesophageal echocardiography (TOE) offers real-time imaging capabilities.

Purpose of the Study:

• To evaluate the utility of transoesophageal echocardiography (TOE) in facilitating central venous catheter (CVC) insertion.
• To assess the impact of TOE guidance on CVC insertion success and complications in cardiac surgery patients.

Main Methods:

• Prospective observational study including 35 patients undergoing elective cardiac surgery and CVC insertion.
• Transoesophageal echocardiography (TOE) was used to visualize the bicaval view prior to CVC insertion.
• Data collected included CVC insertion site, guidewire visualization, and procedural difficulty.

Main Results:

• The bicaval view was obtained in 31 out of 35 patients.
• Successful CVC access at the first attempt occurred in 31 patients, with guidewire visualization in all.
• One patient had an unexpected superior vena cava thrombus, altering CVC insertion strategy.
• Difficulties were encountered in 3 patients despite guidewire visualization or insertion attempts.

Conclusions:

• Routine use of TOE during CVC insertion may help avoid potential complications.
• Maximizing TOE benefits involves routine visualization of the bicaval view during guidewire insertion.
• TOE can provide critical information, such as detecting thrombi, influencing clinical management.
