Lice are spread through direct contact as they crawl. Indirect contact (through brushes or hats) is less likely. One study showed that live lice were found in only 4% of infested volunteers pillowcases.
During an initial infestation, lice can reside on the head for up to 4 to 6 weeks before becoming symptomatic. Therefore, when lice are detected at school, there is no need to send the child home (or to the ED). Children also do not need to be kept out of school while receiving treatment.
Bonus: First line treatment is 1% Permethrin applied on day 0 and 9. The patient should wash their hair first with a non conditioned shampoo, apply Permethrin for 10 minutes and then rinse.

Approximately ¼ of lumbar punctures (LP) are traumatic or unsuccessful in infants. What is the implication of this?
A retrospective cross sectional study over a 10 year period at Boston Children’s Hospital looked at infants aged 28 to 60 days who had blood cultures sent from the Emergency Department and who had LPs performed. The ED clinicians at this facility routinely follow the “Boston Criteria” to identify infants at low risk for spontaneous bacterial infection (SBI). Traumatic LPs were defined as CSF red cell count greater than or equal to 10x10^9 cells/L while an unsuccessful LP was defined as one where no CSF was available for cell counts. A small portion of the unsuccessful LPs did not have CSF cultures sent.
173 infants had traumatic or unsuccessful LPs. The SBI rate did not differ between the normal LP and the traumatic and unsuccessful LP infants. Median hospital charges were higher in the traumatic or unsuccessful LPs compared to the normal LP group ($ 5117 US dollars versus $ 2083 US dollars).
Bottom Line: Traumatic or unsuccessful LPs lead to higher hospital charges.

ISPAD (International Society for Pediatric and Adolescent Diabetes) Updated their Guidelines for Pediatric Diabetic Ketoacidosis (DKA) in 2014
Fluids:
· Begin fluid repletion with 10-20ml/kg of 0.9% NS over 1-2 hours
· Estimate losses (mild DKA <5%, moderate 5-7%, severe ~10%) and replete evenly over 48 hours
o Use NS, Ringers or Plasmalyte for 4-6 hours
o Afterwards use any crystalloid, tonicity at least 0.45% NaCl
· Add 5% glucose to IV fluid when glucose falls below 250-300mg/dL
Insulin
· No bolus
· Low dose 0.05 - 0.1U/kg/hr AFTER initiating fluid therapy
o higher incidence of cerebral edema in patients given insulin in 1st hour
· Short acting subQ insulin lispro or aspart can be substituted for drip in uncomplicated mild DKA
· Give long acting subQ insulin at least 2 hours before stopping infusion to prevent rebound
Potassium
· If K low (< 3.3): add 40mmol/L with bolus IV fluids (20mmol/L if rate > 10ml/kg/hr)
· if K normal (3.3-5): add 40mmol/L when insulin is started
· If K high (> 5): add 40mEq/L after urine output is documented
Bicarb
· No role for bicarbonate in treatment of Pediatric DKA
o No benefit, possibility of harm (paradoxical CNS acidosis)

This study is a case control study of the association of congenital heart disease (CHD) and stroke using a base population of 2.5 million Kaiser patients in California. 412 cases of stroke were identified and compared to 1236 controls. Of these stroke patients, 11/216 ischemic strokes and 4/196 hemorrhagic strokes were attributed to CHD (both cyanotic and acyanotic lesions). CHD was found in 7/1236 controls.
Children with CHD and history of cardiac surgery had the strongest risk of stroke (31 fold over the control group). Many of these children had strokes years after their surgery. Children with CHD who did not have cardiac surgery had a trend towards elevated stroke risk, but the confidence intervals included the null. More children without CHD history presented with headache.
Bottom line: Stroke risk (both hemorrhagic and ischemic) extend past the immediate postoperative period in patients with CHD.

Pediatric Caffeine Overdose
As the in-service draws closer and the hours to study wind down, I find myself becoming more and more of a caffeine enthusiast. While a No-Doz or Diet Mt. Dew may put a little more pep in my step, the caffeine found in energy drinks, caffeine pills, and diet supplements can quickly result in an dangerous overdose in a young child.
Caffeine Overdose Presentation- Sympathomimetic Toxidrome
Available Sources of Caffeine-
Toxic Doses
Management- treat the symptoms (metabolic, cardiovascular, and neurologic)
Good Luck on the In-Service!

Of pediatric patients who have anteroposterior (AP) pelvic xrays (XR), there is a 4.6% rate of pelvic fracture or dislocation, compared to 10% in adults.
This study is a sub analysis of a prospective observational cohort of children with blunt torso trauma conducted by PECARN. 7808 patients had pelvic imaging, with 65% of them having an AP XR. The XR sensitivity ranged from 64-82% (based on age groups) for detecting fractures. All but one patient with a pelvic fracture not detected on XR had a CT scan. The CT scan detected all but 2 fractures both of which were picked up later as healing fractures on repeat pelvic XR. Some of the patients who had a missed fracture on XR were hemodynamically unstable or wound up requiring operative intervention.
The authors support the following algorithm:
-With hemodynamically unstability children, obtain a pelvic XR
-For hemodynamically stable children when the physician is planning to get a CT, there is no indication for XR
Bottom line: Consider using AP pelvic radiographs in the hemodynamically stable patient with a high suspicion for fracture or dislocation who are not undergoing CT.

Are you comfortable with Intraosseous Catheter Placement in Children during a code? A pediatric code or child in distress is also distressing to care providers. Your staff may not feel comfortable with IO access in children. Read on to be more comfortable with your options as IO access in children can be difficult, especially the chubby toddlers. The basics for a patient in distress are "IV, O2, Monitor". Access is vital to giving resuscitation medications.
Indications for IO access: Any child in whom IV access cannot readily be obtained, but is necessary.
All IOs are 15G for infusion equal to central vascular access.
Different colors indicate different sizes:
Preferred sites:
Kids-do NOT use the sternum or distal radius
The reference from NEJM has videos to review placement and different tools (manual, EZ IO, and autoinjector).

Cyanotic (right to left shunt) Congenital Heart Disease (CHD) lesions can be easily remembered with the 1,2,3,4,5 method.
1- Truncus Arteriosis (ONE trunk)
2- Transposition of the Great Vessels (TWO vessels flipped)
3- TRIcuspid Atresia
4-TETRAlogy of Fallot
5- Total Anomolous Pulmonary Venous Return (TAPVR=5 words/letters)
A few other important DUCTAL-DEPENDENT lesions: Coarctation of the Aorta, Hypoplastic Left Heart Syndrome, and Pulmonary Atresia.
Patients present to the emergency department within the first week of life in severe distress, including hypoxia, tachypnea, and hypotension. The above cyanotic CHD all reflect DUCTAL-DEPENDENT lesions, meaning they need a widely open PDA (which closes in the first week of life) to maintain sufficient oxygenation for viability.
These patients will not survive without timely intervention with prostaglandin (PGE1), so be sure to initiate this life-saving medication as soon as possible! Side effects include apnea…be prepared to intubate your neonate!

Now that respiratory season is upon us, we are faced with an increasing number of bronchiolitis children. The updated clinical practice guidelines for managing these kids were recently published and emphasize supportive care only.
Some of the key points:
-When clinicians diagnose bronchiolitis on the basis of history and physical examination, radiographic or laboratory studies should not be obtained routinely.
-Medications such as albuterol, nebulized epinephrine or steroids should not be administered routinely in children with a diagnosis of bronchiolitis.
-Nebulized hypertonic saline should not be administered to infants with a diagnosis of bronchiolitis in the emergency department
-Clinicians may choose not to administer supplemental oxygen if the oxyhemoglobin saturation exceeds 90% in infants and children with a diagnosis of bronchiolitis
-Clinicians may choose not to use continuous pulse oximetry for infants and children with a diagnosis of bronchiolitis.
Check out the full guidelines for the quality of evidence and rational behind these recommendations.
The bottom line is that not much really works, and we just need to support their respiratory effort and ensure hydration.

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.

Emergency Physician Bedside Ultrasound for Appendicitis
Why?
To reduce length of stay, improve patient care, and reduce radiation exposure in young patients.
How?
Start with pain medication so you get a better study. (Consider intranasal fentanyl for quicker pain relief and diagnostics in pediatrics.) Study results are also improved with a slim body habitus.
Place the patient supine
Use a high-frequency linear array transducer
Start at the point of maximal tenderness in the RLQ
Transverse and longitudinal planes "graded compression" to displace overlying bowel gas which usually has peristalsis (See Sivitz, et al article for images of "graded compression")
Appendix is usually anterior to the psoas muscle and iliac vein and artery as landmarks
Measure from outer wall to outer wall at the most inflamed portion of the appendix (usually distal end)
Example:
Positive study:
A non-compressible, blind-ending tubular structure in the longitudinal axis >6 mm without peristalsis (see second image above with 8.3 mm diameter measurement)
A target sign in the transverse view (see first image above)
Additional suggestive findings: appendiceal wall hyperemia with color Doppler, appendicoliths hyperechoic (white) foci with an anechoic (black) shadow, periappendiceal inflammation or free fluid
Negative study:
Non-visualization of the appendix with adequate graded compression exam in the absence of free fluid or inflammation.
Limitations for visualization and possible false negative result:
Retrocecal appendix and perforated appendix are difficult to visualize with US.
Pitfalls:
US has good specificity (93% in Sivitz et al article), but limited sensitivity (85% in Sivitz et al article), so trust your clinical judgement. You may need a MRI (pregnant/pediatrics) or CT as they have improved, but not perfect sensitivity.

The world of pediatrics is still working on catching up to adult literature in terms of lactate utilization and its implications. The study referenced looked at over 1000 children admitted to the pediatric intensive care unit. Lactate levels were collected 2 hours after admission and a mortality risk assessment was calculated within 24 hours of admission (PRISM III). Results showed that the lactate level on admission was significantly associated with mortality after adjustment for age, gender and PRISM III score.
Bottom line: In your critically ill pediatric patient, lactate may be a useful predictor of mortality.
