Bedside Ultrasonography

ABSTRACTObjective:Our goal was to gain a better understanding of the femoral vessel anatomy as it relates to central venous cannulation. The primary objective of this study was to use bedside ultrasonography to determine the amount of exposed femoral vein at three sites corresponding to surface anatomy of the landmark-based procedure.Methods:This cross-sectional study enrolled a random sample of 180 adult patients presenting to a large urban academic emergency department. Subjects underwent standardized ultrasonography to identify and measure the depth and diameter of the femoral vessels and amount of exposed femoral vein at the level of the inguinal ligament (0 cm) 2 cm and 4 cm below. Repeated measures analysis of variance was used to determine significant relationships between vessel measurements and distance from the inguinal ligament.Results:The median age was 44.5 (range 19–90) years; 101 patients were male. The mean (± SD) percentage of exposed vein at the inguinal ligament was 83% (± 21). This decreased significantly (p< 0.01) with increasing distance from the inguinal ligament: 65% (± 25) at 2 cm and 56% (± 30) at 4 cm. At every distance away from the inguinal ligament, there were some subjects with no vein exposed.Conclusion:This study demonstrates significant overlap of the femoral vessels at sites where landmark-based femoral vein cannulation is often attempted. Our results suggest that ultrasound guidance would be beneficial as femoral vein cannulation may be difficult or impossible in certain individuals owing to anatomic variations.

Landmark Technique

Central venous cannulation of infants may be challenging. Ultrasonography is recommended and has been found superior to classic landmark technique in pediatric central venous cannulation. The cannulation of the subclavian vein using supraclavicular approach under real-time ultrasound guidance is a novel technique. It may have advantages over ultrasound-guided jugular vein cannulation in specific patients. We report a case of 3200-gram 20-day-old anencephalic neonate who had a diffuse generalized edema. The neonate was cannulated successfully via subclavian vein using supraclavicular approach under ultrasound guidance.

Background and Aims: Central venous cannulation is a common procedure in intensive care unit. Use of ultrasound guidance can decrease complications and increase successful cannulations. Methods: Patients who underwent ultrasound guided central venous cannulation over a duration of one year, in a single center, were analyzed retrospectively. Results: A total of 101 patients were analyzed. Internal jugular vein was cannulated in 84 (83.2%) and femoral vein was cannulated in 17 (16.8%) patients. Cannulation was successful in all cases. Elective cannulation was performed in 80 (79.2%) of patients and emergency cannulation was performed in 21 (20.8%) patients. Platelet count was less than 50000/cu mm in 30 (29.7%) patients and prothrombin time was more than 13 seconds in 84 (83.2%) patients. Cannulation was successfully performed in first attempt in 99 (98%) patients. None of the patients had arterial puncture, major bleeding, pneumothorax, arrhythmias or catheter malposition. One patient developed hematoma at the catheter insertion site. Conclusions: When performed by an experienced operator, ultrasound guidance can enhance safety and improve success for central venous cannulation.

Complex Patients

In this treatise, we will address one of the higher-risk procedures, subclavian vein cannulation, that a practitioner may undertake in the care of complex patients. All cardiothoracic surgeons and their trainees will need, on occasion, to put in central lines in a variety of circumstances, including in the operating room, in the intensive care unit, in emergency circumstances, and, occasionally, when other practitioners have been unsuccessful in their attempts to place a central line. We will describe, in detail, the anatomy of the subclavian vein, the preparation of the patient for subclavian vein cannulation, the infraclavicular approach to cannulation of the vein, and a few notes about the supraclavicular approach to the subclavian vein. It is self-evident that the priorities of central venous cannulation include safety of insertion, minimizing clot formation, and avoiding infection. We will dwell primarily on the principles of safe subclavian line insertion.
