Purpose:
Policy statements recommend the use of ultrasound guidance (USG) to improve patient safety during placement of central venous catheters (CVCs). Studies have conclusively demonstrated greater success rates and fewer complications with the use of USG in catheter placement using the internal jugular vein approach. Data supporting the use of USG for the subclavian vein (SCV) approach, however, have been less conclusive, and USG for SCV cannulation is rarely used in clinical practice. We compared USG placement versus anatomic placement during subclavian insertion of a CVC.
Methods:
A prospective randomized study was performed in March 2010 using a simulation model.
Results:
Ultrasound guidance did not provide a statistically significant benefit for successful cannulation of the SCV (93.3% with USG and 100% without; P=0.15 or 2) or for rate of inadvertent arterial puncture (3.3% with USG and 0% without; P=0.31).
Conclusions:
The use of USG to access the SCV utilizing a task trainer did not improve time to cannulation or success rates. Further study is required to delineate why USG for SCV cannulation has not been widely adopted in clinical practice.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
