Tip of the Day

The sensitivity of TTE for detecting endocarditis is moderate in native valves but the absence of findings cannot be used to rule out the diagnosis
The Jellyfish sign is seen on thoracic ultrasound when the collapsed lung is seen moving with respiration within the pleural effusion
The twinkle artifact is a color Doppler phenomenon characterized by a rapidly alternating mixture of red and blue colors behind or within a strongly reflective, typically rough-surfaced object, such as urinary stone, calcification, or metallic foreign body.
The presence of a twisted spermatic cord when visualized with color Doppler is known as the “whirlpool sign” and can be seen in testicular torsion
Ultrasound has high sensitivity for the detection of non-radiopaque soft tissue foreign bodies
The FAST exam is poorly sensitive for the detection of intra-abdominal injury in penetrating abdominal trauma
Having the patient bend their knees when performing an abdominal ultrasound can help relax the abdominal muscles and reduce bowel gas interference
Ultrasound is poorly sensitive for the detection of hemoretroperitoneum
Lung sliding seen on the m-mode appears as the “sea-shore sign”
B-lines are discrete vertical reverberation artifacts that originate from the pleural line and obscure A-lines and are not seen in pneumothorax
When performing the perisplenic window of the FAST exam keep “knuckles to the bed.”
Increasing the number of focal zones will improve resolution but will slow down the frame rate
Retinal detachments appear as a hyperechoic, undulating membrane tethered at the optic disc
Having the patient take a deep breath when performing the perisplenic window will result in the curtain effect due to air in the costophrenic angle blocking visualization of the spleen and left kidney
The main lobar fissure connects the gallbladder neck with the portal vein
Papilledema is detected as optic disc elevation with ultrasound being moderately sensitive and specific for this finding
Biparietal diameter is measured at the level of the thalami and cave septic pellucidi
Having the patient take a deep breath can be used to improve visualization of the gallbladder
LV ejection fraction is not the same as cardiac output
When a kidney is not visualized in the renal fossa, scan the pelvis to evaluate for a pelvic kidney which is typically located just anterior to the sacrum and adjacent to the urinary bladder
The abdominal aorta is measured outer-edge to outer-edge
The sonographic Murphy’s sign is sensitive but not highly specific
Pericholecystic fluid is supports the diagnosis of acute cholecystitis but is not specific
Severe tricuspid regurgitation can result in pulsatility of the portal vein
Biparietal diameter is measured from the outer edge of the proximal skull to the inner edge of the distal skull
Classic findings of molar pregnancy include heterogenous, echogenic intrauterine mass with numerous small cystic spaces (snowstorm or cluster of grapes pattern)
In complete molar pregnancy there is typically absence of a fetus or amniotic sac, but in partial molar pregnancy a gestational sac with a fetus can be visualized
An intraocular foreign body appear as a hyperechoic structure with posterior acoustic shadowing and ultrasound is highly accurate for detection
Low pressure cardiac tamponade is a clinical syndrome in which pericardial fluid accumulation impairs cardiac filling despite normal or only mildly elevated intracardiac pressures, often occurring in hypovolemic or critically ill patients
VEXUS is a semi-quantitative, multi-organ Doppler-based assessment of venous congestion and integrates inferior vena cava diameter and collapsibility, hepatic vein Doppler, portal vein pulsatility, and infrarenal vein Doppler patterns to grade congestion severity from 0 (none) to 3 (severe)
When hydronephrosis is detected in one kidney, scan the other kidney as well as the urinary bladder
Severe congestion (VEXUS grade >/= 2) is associated with increased risk of acute kidney injury (cardiorenal syndrome)
Renal parenchymal echogenicity is compared with the echogenicity of the liver or spleen
VEXUS grade does not correlate well with clinical edema, highlighting the limitations of physical exam for venous congestion
Hydronephrosis can be caused by intrinsic and extrinsic causes

Reactive submandibular lymph node with oval shape, presence of echogenic hilum, well-defined border, and increased vascularity. While ultrasound cannot be used to definitively differentiate benign vs. malignant lymph nodes, malignant lymph nodes tend to lack an echogenic hilum, have irregular or indistinct margins, display heterogeneous echo texture, and often show peripheral or mixed vascularity.

Comment by Dr. Jones

It is clear that POCUS is often under documented and under billed and this can have medicolegal risks, as well as significant revenue loss. The time required to order the study in the EHR, upload the images, and then document in the EHR can be time-consuming and is a commonly cited reason by physicians as the reason they did not document the examination. Simple solutions could include sending an email reminder to the physician but this study demonstrated limited durability to a single e-mail reminder as an intervention to improve POCUS documentation in the ED.

This study is limited by the fact that it is a single center study and involves a small number of study participants, but it brings up some interesting points. Many would consider determining the presence or absence of lung sliding to be a very basic POCUS skill. It is interesting that the interrater agreement, determined by an ICC was 0.44 for B-mode and 0.43 for M-mode. A limitation could be that the study participants did not have the ability to adjust the machine settings or to scan adjacent areas. Further studies will need to be done to determine solutions—? Perform both B-mode and M-mode before making diagnosis. ? Use of AI. ? Increase minimum number of studies performed before credentialing.

This study, while limited by its retrospective design, has drawn similar conclusions to what has been found in the anesthesiology literature, but further studies will need to be done to see if there are unique outcome differences in the ED setting using prospective studies. They found that dexamethasone had an association with improved pain control within 60 minutes without additional safety concerns. Dexamethasone is a well supported adjuvant for peripheral nerve blocks, prolonging analgesia and reducing rebound pain and opioid use based on studies in the anesthesiology literature. It is important to keep in mind that dexamethasone can be administered intravenously or perineurally with intravenous administration offering comparable efficacy at higher doses and a more established safety profile based on those anesthesiology studies.

Comment by Dr. Cristin Mount

This JAMA Network Open study asked whether POCUS for patients admitted with undifferentiated dyspnea could shorten hospital stays and cut costs.

At a single academic center, hospitalists got one-on-one training and did a 6-view cardiac and an 8-zone lung POCUS on day one of admission, backed up by sonographers with remote cardiologist interpretation. They found that POCUS patients had about a 30% shorter length of stay, saving nearly $750k in bed-day costs.

However, 80% of scans were done by sonographers, not hospitalists—so it’s hard to see this working outside a well-resourced tertiary academic center. Hospitalists cited lack of training, limited time on rounds, and no real incentives to incorporate POCUS as barriers.

Seamless integration of cardiopulmonary POCUS into hospitalist practice will require better, more longitudinal training, workflow integration, and institutional buy-in.

In conclusion, this study highlights POCUS as a promising tool to shorten hospital stays and lower costs, pointing to real opportunities if training and integration improve, however, adoption in smaller, less well-resourced hospitals may not show the same results.
