How do you place a subclavian central line in an ultrasound?
With the patient in the supine position (if possible), place the probe in the infraclavicular fossa and identify the vasculature 2-3 cm distal to where the subclavian vein courses below the clavicle. Cannulation occurs more laterally as compared to the landmark approach.
Is ultrasound standard of care for central line placement?
Real-time (rather than static) ultrasound guidance is the safest, most cost-effective, and successful method for CVC placement compared with the traditional percutaneous landmark-based approach for cannulation of the internal jugular vein.
Which vein should be avoided for central line placement?
Thus the femoral vein should be avoided due to a high rate of colonization and thrombosis while the subclavian vein seems to exhibit fewer infectious complications compared with other sites.
Where should femoral central line be placed?
The site to choose should be 1-2 cm below the inguinal crease, about 1cm medial to the femoral pulse. Be sure to enter below the inguinal crease to avoid retroperitoneal puncture.
What is a subclavian line?
The subclavian veins are an often favored site for central venous access, including tunneled catheters and subcutaneous ports for chemotherapy, prolonged antimicrobial therapy, and parenteral nutrition.
How long does femoral line last?
In general, femoral vein cannulation is not preferred because the groin site is difficult to keep clean and patient ambulation is difficult. These lines should not be kept for more than 24 to 48 hours.
What happens if central line inserted too far?
Conversely, if the catheter is inserted too far and enters the right atrium or right ventricle, arrhythmias or, less commonly, perforation of the myocardium can occur.
What is the supraclavicular approach to ultrasound-guided central venous venous cannulation?
The supraclavicular approach to ultrasound-guided SCV cannulation may be ideal in certain scenarios and safer than the landmark-based SCV central line placement. 2,3,11 We recommend this access site as an alternative for providers comfortable in procedures requiring in-plane needle visualization.
What is the supraclavicular approach to the subclavian vein?
Abstract While the supraclavicular approach to the subclavian vein has been described since 1965, it is generally employed much less often than the “traditional” infraclavicular approach.
What is the difference between the supraclavicular and infraclavicular approach?
With the supraclavicular approach, the SCV is often shallow and easily visualized as compared to the infraclavicular approach, making for an ideal site for central venous cannulation. The SCV runs from lateral to medial under the clavicle, just anterior to the subclavian artery (SCA).
Should a novice sonographer be able to perform ultrasound-guided SCV cannulations?
Before attempting either of these more challenging ultrasound-guided SCV cannulations, we recommend novice sonographers obtain comfort with both the ultrasound-guided IJV or femoral vein cannulation as well as attain proficiency with in-plane needling technique.
