Trick of the Trade: Save the Ultrasound Probe Cable

You need to perform an ultrasound on your patient. You walk up to the ultrasound and upon grabbing the machine, you notice it’s stuck! You look down and realize the ultrasound probe cable (particularly the linear probe) is impeding the wheel from rolling. You push the machine back, pick the cable up off the floor and off you go to scan to find that the probe is not working. As you try to figure out why it’s not working, you realize that the cable is exposed after repeated damage from the countless times the wheels on the machine rolled over the cable. Let’s prevent this from happening!

Techniques for Ultrasound-Guided IV Placement

Y junction access

Imagine a busy evening shift interrupted by the news that the unstable dialysis patient still has no access. Begrudgingly, you drag the ultrasound into the patient’s room. Buried beneath a layer of muscle, a tiny vein lurks below an intimidating artery with a nerve nestled close by. Making matters worse, the patient is becoming increasingly more frustrated. “This always happens. I told them not to remove my last PICC line,” he notes. The use of ultrasound-guided IV improves successful cannulation and decreases complications, but cases like this have caused many emergency providers to resent, even fear, this basic procedure.​1–4​ Below, we provide additional techniques to increase your success and to avoid the risks associated with central line placement.

Differentiating pericardial effusion from pericardial tamponade on ultrasound

Tamponade physiology, in which a pericardial effusion impedes cardiac output, is a medical emergency and requires prompt diagnosis and intervention before cardiovascular collapse ensues. However, not every fluid collection in the pericardial sac results in tamponade physiology. A clinical diagnosis of tamponade (Beck’s triad) has poor sensitivity and will occur only in the late stages of tamponade.​1​ In order to know whether or not an intervention is necessary for the setting of pericardial effusion, ultrasound diagnosis of tamponade is paramount.

Fascia iliaca nerve block: A hip fracture best-practice

fascia iliaca nerve block hip fracture

An 82-year-old woman presents with left hip pain after a mechanical fall while cleaning the kitchen floor. When EMS arrived, the left leg was foreshortened and externally rotated. The paramedics administered 10 mg of IV morphine, but she is still writhing in pain on arrival. The AP pelvic x-ray demonstrates a left femoral neck fracture (arrow). You consider performing a fascia iliaca nerve block for better pain control.
