UMEM Educational Pearls

Lower GI bleed is a common reason for ED visits. This study aimed to validate a scoring system to identify low-risk LGIB pts who could be safely discharged from the ED.

The SHA2PE score incorporates characteristics and data that are commonly collected on patients with this complaint; readers can click through to see the scoring system. A score of less than or equal to 1 helps identify patients suitable for outpatient management, with a NPV of 98.3% (95% CI [97.2-99.1]) for predicting the need for hospitalization and acute intervention.  However, the findings should be interpreted with caution given the relatively low prevalence of interventions within the study population.

Should we give a dose of antibiotics after intubating to reduce risk of VAP down the line? A multicenter RCT conducted in 2024 - the PROPHY-VAP Trial - found that a single dose of 2g ceftriaxone administered within 12 hours of intubation reduced VAP within the first week of hospitalization for patients intubated for airway protection due to TBI, stroke or SAH, with a VAP rate of 14% in the CTX group vs 32% in the VAP group (HR 0.60; 95% CI 0.38-0.95).

In 290 trauma patients diagnosed with dementia prior to injury, when compared to 3000 patients over age 65 without dementia and similar injury severity score, the dementia patients had a much higher rate of discharge to an institution instead of back to home living. This was particularly true of older women.

BOTTOM LINE: It is critical to recognize and treat symptomatic hypocalcemia in pediatric patients. 

Pediatric hypocalcemia has a variety of causes that should be considered. In the neonate congenital causes should be on the differential.

  • In neonates, common causes include prematurity, infections, and maternal diabetes
  • In infants and children vitamin D deficiency is most common, with rare causes including genetic etiologies, hyperparathyroidism and pseudohypoparathyroidism

Parathyroid hormone levels should be checked on all patients along with magnesium levels and ionized calcium.  

An ECG should also be obtained for prolonged QTc. 

Management is guided by acute symptoms (tetany, seizures, cramping, etc.) or other signs of critical illness (sepsis, trauma, etc.) in conjunction with low ionized calcium levels. 

For symptomatic patients give 20 mg/kg of elemental calcium IV over a 10–20 min period

  • 2 ml/kg of 10% calcium gluconate OR
  • 0.7 ml/kg of 10% calcium chloride

For asymptomatic patient oral calcium supplements are typically given. 

Failure to recognize concomitant hypomagnesemia may result in hypocalcemia that is resistant to treatment. 

Disposition: Those children receiving IV calcium should be admitted with every 4-to-6-hour calcium levels and typically require ICU level admission. Children being monitored with oral supplementation can often be observed on a pediatric floor presuming there are no ECG abnormalities.

This article describes a paramedic run community health initiative to assist people with dementia transition to home after an ED visit. They describe:

“Persons living with dementia (PLWD) frequently use the emergency department (ED) for unscheduled care and experience significant challenges during the ED-to-home transition.

The Community Paramedic-led Transitions Intervention (CPTI) is a structured, coaching-based program delivered by community paramedics that includes a home visit and follow-up calls to support PLWD and care partners during the 30?days after ED discharge.”

Could your ED use a program like this to prevent readmissions?

Bottom Line: Multiple modalities of intervention may be needed to combat various aspects of salicylate toxicity. These include gastric decontamination, fluid hydration, dextrose admiinistration, aggressive serum alkalinization, establishment of normokalemia and hemodialysis. Intubation and chemical restraint should be avoided if possible.

A retrospective study looking at use of transdermal Buprenorphine in older trauma patients with rib fractures found a good safety profile (less naloxone use) and less overall opioid use however no change in overall length of stay or mortality. Adding this to your multimodal pain strategy in older patients with rib fractures seems like a reasonable plan.

A narrative review of literature involving older patients and constipation found:

“Major contributing factors include physical inactivity, sarcopenia, dehydration, inappropriate defecation posture, and polypharmacy, particularly opioids and anticholinergic agents. Importantly, these factors interact through the brain–gut–microbiota axis, contributing not only to gastrointestinal dysfunction but also to systemic outcomes such as frailty, cognitive decline, and increased healthcare burden, thereby supporting a multidimensional disease framework.”

It isn’t as simple as adding a laxative.

Body armor/ bullet resistant vests used by law enforcement are designed to stop penetration by handgun rounds. These rounds have less velocity than rifle rounds. When caring for someone who has been shot while wearing body armor, verify no penetration has occurred and then look for blunt injuries such as rib fractures, liver injuries, pneumothorax, cardiac contusion, vertebral injury, etc. Behind Armor Blunt Trauma (BABT) is the technical term for injuries caused by the transfer of kinetic energy that occurs when these vests are struck.

This narrative review of the trauma literature looking at chronic pain after trauma found: 

  1. Chronic pain occurs in 30–70% of trauma survivors, with prevalence varying by injury type. 
  2. Key risk factors include female sex, younger age, pre-existing pain, psychological distress, and social disadvantage. 
  3. Validated prediction models are available for musculoskeletal trauma
  4. Thoracic trauma is under represented in the pain literature, is often underrecognized, and less protocols are available for treatment
  5. Thoracic pain typically occurs through intercostal nerve damage and persistent pain following thoracic injury
  6. The authors suggest “A trauma-specific, biopsychosocial approach is key to reducing chronic pain and improving recovery.”

Title: P:F vs S:F Ratio

PaO2 to FiO2 (P:F) ratios, are often considered the gold standard in critical care for assessing the degree of oxygen-refractory hypoxia in various pathologies, particularly ARDS.  P:F does have some limitations, including not accounting for the PEEP, but probably the most limiting is that it requires collecting an ABG, which is invasive and not always feasible or a top priority when resuscitating a critically ill hypoxic patient.  On the other hand, SpO2 (pulse ox saturation) is routinely available, and of course the FiO2 should be known, so many have suggested perhaps using an SpO2 to FiO2 (S:F) ratio instead.  But how S:F maps to P:F and how well they correlate is not fully known.  Chaudhuri et al recently conducted a meta-analysis, published in Critical Care Medicine this month, which reviewed the literature on this. 

Bottom Line: Yes, S:F ratios correlate well with P:F ratios, especially when the SpO2 is less than 97%, but you can't just substitute the S:F for P:F, you have to use one of the accepted formulas.  See additional info on the website for the actual formula to apply and how a given S:F translates to P:F.

Multiple past studies have shown that Black and female patients tend to be prescribed fewer opioids than White and male patients. This study looked at the rates of opioid usage post RSI.

They found that while Black patients received opioids at a higher rate, they were given lower doses than white patients. Older patients were less likely to receive opioids post RSI than younger patients.  They did not find a difference in rates of opioid usage between genders, but female patients received lower doses of opioids overall.

Pancreatic injury in pediatric blunt abdominal trauma is rare. 

This study was a secondary analysis of the data collected by the Pediatric Emergency Care Applied Research Network (PECARN) in the Intra-abdominal Injury Study Group. Of the children who had blunt abdominal trauma, 6% had intraabdominal injuries and 1% had pancreatitis.  A patient was considered as having traumatic pancreatitis if they had 2 of the following: 1) upper abdominal tenderness, 2) serum lipase of amylase > 3 x the upper limit of normal or 3) imaging study positive for pancreatitis.

Cervical spine injuries (CSI) are uncommon in children, but when present, they are often devastating.  However, the application of a cervical collar in children is not benign and adverse effects include neck pain and discomfort and the downward tunnel vision it may create at the hospital leading to unnecessary testing.  Recently, the PECARN group published a set of criteria to determine who requires imaging of the cervical spine in the emergency department.  A planned subset of this initial study was to collect the impressions of EMS as they pertained to the 9 criteria to determine if these criteria could safely be used by EMS.  The patients who were brought in by EMS with the potential for cervical spine injury, who were evaluated by the trauma team and/or had cervical imaging AND had electronic case reports filled out by EMS were included in the final analysis.  Only 57% of the patients possible could be included based on the number of electronic case reports that were filled out.
