TABLE OF CONTENTS
Nurses’ scope of practice has been consistently expanding in recent decades, and the integration of new technologies such as ultrasound, is no exception. Point of care ultrasound (POCUS) is safe, portable, and enhances patient care. With the increasing availability of hand-held devices, nursing-performed POCUS has become an important skill for the 21st century nurse.
Let’s explore three key areas where ultrasound improves nursing care.
The first-generation Bladder Scan BVI 2000 was released in 1986, with numerous advancements of this technology since then. Its core uses are for postvoid residual assessments, post-catheter discontinuation assessments, and prior to intermittent catheterizations. These assessments help eliminate trauma and injury associated with unnecessary catheterization or an overdistended bladder.
In 2001, a study at London Health Sciences showed that bladder scanners were highly accurate in detecting who had a distended bladder and had an important effect on the nurse’s decision on whether to proceed with catheterization. Today, bladder scanners are an integral tool used by nurses in most acute care settings.
Assessment of peripheral pulses is essential when evaluating for systemic and limb perfusion. Providers often find it challenging to detect peripheral pulses in patients with diabetes, peripheral vascular disease, sepsis, high vasopressor requirements, and those who have recently undergone cardiac procedures.
Nursing performed doppler ultrasound technology helps quickly and accurately verify blood flow in order to rectify this problem. An investigation by Ross et al. (2007) showed that adding Doppler ultrasound to manual assessment increased accuracy of pulse assessment by 9.6% in vascular nurse specialists and 15.1% in general nurses.
Initial vascular assessment, venipuncture and insertion of peripheral IVs are core nursing skills. However, factors such as obesity, trauma, shock, and previous venous access can make it difficult to cannulate the vein. Failure to establish IV access can lead to delays in treatment and can necessitate central line placement by physicians or specialized nurses.
In recent years, nursing-led ultrasound for difficult peripheral IVs has helped mitigate these concerns, expedite patient care, and avoid escalation to specialized providers for routine procedures. A randomized controlled trial conducted by Bahl et al. demonstrated that a nurse using an ultrasound-guided technique had a 76% success rate in placing a functional IV compared to 56% success rate using the traditional palpation technique in patients with difficult vascular access.
Over the years, as ultrasound technology has advanced in healthcare, nurses have demonstrated growing confidence with its use and have furthered its application into everyday practice. The question is not a matter of ‘if’ nursing ultrasound enhances patient care, but rather ‘how’ it can be integrated into practice most effectively. As new frontiers of ultrasound emerge, nursing ultrasound to assess for causes of dyspnea, hypotension, acute kidney injury, and fluid status have all become exciting areas of future investigation. At Deep Breathe, we are working closely with nurses to empower them to obtain and interpret lung ultrasound images in conjunction with AI technology. Learn more about it here.
