Background Arterial catheterizations, especially of radial and femoral arteries, are very common procedures performed by physicians dealing with critical patients for invasive hemodynamic monitoring and frequent arterial blood sampling. Traditionally, the technique of locating surface landmarks and palpation was used in catheterization. Getting arterial access can be challenging in critical patients with hemodynamic instability, impalpable pulses, and coagulopathy. Our objective was to study the effectiveness of vascular ultrasound in arterial catheterization in critical patients with nonpulsatile circulation admitted at cardiac critical care units in comparison with the landmark technique. Patients, methods, and results This retrospective study was conducted in a tertiary care hospital and included patients from January 2015 to November 2018 who were admitted to adult cardiac critical care unit with veno-arterial extracorporeal membrane oxygenation or left ventricular assist device and required arterial vascular access for invasive hemodynamic monitoring. A total of 124 vascular catheters were inserted in 109 critical patients. Overall, 87 (79.8%) patients were hemodynamically unstable and supported with vasopressors infusions. Heparin infusion was maintained in 91 (83.4%) patients, while 18 (16.51%) patients were anticoagulated with oral warfarin therapy during arterial catheterization. The first-attempt success was achieved in 78.9 versus 5.6% (P=0.001) and the procedural success rate was 100 versus 62.1% (P=0.001) in the ultrasound and landmark groups, respectively. The number of attempts was 1.2±0.4 versus 2.1±0.5 (P=0.001), and the hematoma occurred in 2.8 versus 11.1% (P=0.001) in the ultrasound and landmark groups, respectively. Conclusion Ultrasound-guided arterial catheterization in critical patients with unstable hemodynamics and nonpulsatile continuous circulation was associated with higher first-attempt and procedural success and less complications compared with the landmark technique.
