Arterial Lines

Arterial Lines

The insertion of the arterial lines catheter by means of a blind palpation technique, without ultrasound guidance, sometimes requires multiple attempts and thus contributes to patient discomfort and predisposes the patient to bleeding and arterial spasm.

Successful arterial catheterization can be challenging in patients who are obese and in patients with edema, hypotension, or vascular anomalies, such as tortuous vessels.

Which ultrasound scanner do doctors use for the insertion of arterial lines?

Doctors prefer the SIFULTRAS-3.5 as it is has a built in needle guide.

Ultrasound guidance (USG) is faster and more successful than traditional blind palpation (TBP) for radial artery line placement. In order to assess the vasculature, you will need a linear-array transducer ultrasound probe with a frequency range of 5 to 13 MHz.

The ultrasound guidance can be more effective than palpation for the insertion of a radial arterial catheter in such patients. Ultrasonography can also decrease patient anxiety and discomfort and can reduce procedure-related complications .

Once the radial artery has been identified using the ultrasound scaner, have the assistant adjust the gain to optimize the contrast between the black vessels and the surrounding structures. Next, adjust the depth so that the artery appears in the center of the ultrasound screen and is clearly visible. As you scan the artery from the wrist to the antecubital fossa, look for arterial tortuosity and calcification. Locate a section of the artery with a large diameter and minimal calcification.

Arterial lines are typically inserted by Physicians, Anesthesiologists, Acute Care Nurse Practitioners (ACNP), ICU Physician Assistants (PAs), Anesthesiologist Assistants (CAAs), Nurse Anesthetists (CRNAs), and Respiratory Therapists.
