Question
Patient: A 10 year old female is brought to the ED after swallowing 2 beads (see image). Based on the findings, what are your concerns and what is the disposition?
Dehydration is a common pediatric ED presentation. Oral rehydration (although first choice) is often not possible secondary to patient cooperation and/ or persistent vomiting. Intravenous (IV) hydration is often difficult, requiring multiple attempts especially in the young dehydrated infant.
Hyaluronan is a mucopolysaccharude present in connective tissue that prevents the spread of substances through the subcutneous space. Hyaluronidase is a human DNA-derived enzyme that breaks down hyaluronan and temporarily increases its permeability, thereby allowing fluid to be absorbed with the capillary and lymphatic systems.
In one study, patients age 1 month to 10 years were randomized to recieve 20 mL/kg bolus NS via subcutaneous (SC) or IV route over one hour, then as needed. The mean volume infused in the ED was 334.3 mL (SC) vs 299.6 mL (IV). Succesful line placement occured in all 73 SC patients and only 59/75 IV patients. There was a higher proportion of satisfaction for clinicians and parents for ease of use and satisfaction, respectively.
Bottom line: Consider subcutaneous hyaluronidase faciliated rehydration in mild to moderately dehydrated children, especially with difficult IV access.
There are numerous different causes of pediatric hemorrhagic diarrhea. Consider a pediatric patient with bloody diarrhea as being at risk for developing hemolytic uremic syndrome. Most cases of hemolytic uremic syndrome are caused by O157:H7 strains of E Coli that release Shiga-like toxin from the gut. Systemic release of the toxin causes microvascular thromboses in the renal microvasculature. The characteristic microangiopathic hemolysis results with anemia, thrombocytopenia and peripheral schistocytes seen on laboratory studies, in addition to acute renal failure.
Antibiotics have been controversial in the treatment of pediatric hemorrhagic diarrhea due to concern that they worsen toxin release from children infected with E Coli O157:H7 and thus increase the risk of developing hemolytic uremic syndrome. Numerous previous studies have provided conflicting data regarding the true risk (1). A recent prospective study showed antibiotic treatment increases the risk (2). Most recommendations warn against using antibiotics to treat pediatric hemorrhagic diarrhea unless the patient is septic.
Bottom line: Avoid treating pediatric hemorrhagic diarrhea with antibiotics
Cringing at the thought of sewing up another screaming 2 year old?
Consider intranasal fentanyl.
Who: Young, otherwise healthy pediatric patients undergoing minor procedures (laceration repair, fracture reduction/splinting, etc...)
What: Fentanyl (2mcg/kg)
When: 5 minutes pre-procedure
Where: Intranasal
Why: More effective than PO, less invasive than IV while being equally efficacious.
How: Use an atomizer, splitting the dose between each nostril.

An overweight 5 year old male presents with acute onset abdominal pain that localizes to the right lower quadrant. What are some causes of a limited or nondiagnostic ultrasound study in children?
Acute appendicitis is a time sensitive diagnosis. Ultrasound is frequently used as the initial diagnostic imaging in children. There are several reasons why the appendix may not be visualized, including retro-cecal location, normal appendix, perforation, and inflammation around the distal tip. An additional clinical predictor associated with poor or inconclusive ultrasound results in appendicitis is increased BMI (body mass index).
A study examining 263 pediatric patients found when BMI > 85th percentile and clinical probability of appendicitis was <50%, 58% of ultrasounds were nondiagnostic. Children with a BMI <85th percentile and clinical probability of appendicitis was <50%, had nondiagonstic scans 42% of the time. These trends were also mimicked in the patients with a higher clinical probability of appendicitis. In the child with a nondiagnostic ultrasound, options include observation and repeat ultrasound scan or CT scan, both of which have associated risks.
2013 AAP AOM Guidelines UPDATE
You have diagnosed an infant or child with pneumonia. How do you decide if they need admission?
The Pediatric Infectious Disease Society and the British Thoracic Society each have guidelines from 2011 to help with this decision.
In children, it is important to consider the maximum doses of local anesthetics when performing a laceration repair or painful procedure like abscess drainage. If there are multiple lacerations, or large lacerations, it may be possible to exceed those doses if one is not careful.
Max doses of common anesthetics
For example, in a 20 kg child (an average 5-6 year old), the maximum doses would be:

Parents bring in their child who placed a bead, seed, or other object up her nose. What do you do? Who should you call?
Research suggests that a decades-old home remedy (of sorts) known as the “mother’s kiss” may do the trick for children 1-8 years of age. It’s also much less invasive or frightening than some of the tools and techniques used in emergency departments with a success rate approaching 60%
First described in 1965, here’s how the mother’s kiss technique works:
A 1 year old gets sent from their pediatrician’s office for rule out meningitis. They presented with fever for 2 days and neck rigidity. Your LP results are normal. What additional test should you consider?
The incidence of pediatric syncope is common with 15%-25% of children and adolescents experiencing at least one episode of syncope before adulthood. Incidence peaks between the ages of 15 and 19 years for both sexes.
Although most causes of pediatric syncope are benign, an appropriate evaluation must be performed to exclude rare life-threatening disorders. In contrast to adults, vasodepressor syncope (also known as vasovagal) is the most frequent cause of pediatric syncope (61%–80%). Cardiac disorders only represent 2% to 6% of pediatric cases but account for 85% of sudden death in children and adolescent athletes. 17% of young athletes with sudden death have a history of syncope.
Key features on history and physical examination for identifying high-risk patients include exercise-related symptoms, a family history of sudden death, a history of cardiac disease, an abnormal cardiac examination, or an abnormal ECG.
