Bladder ultrasound increases catheterization success in pediatric patients

• Next time before you attemt to catheterize a child under 36 months measure the transverse bladder diameter with the ultrasound first. 
• If it is > 2 cm you are much more likely to be successful in obtaining the specimen on the first attempt. 
• 94% when ultrasound measurement was used versus 68% patients who had conventional catheterization.

In the rush of adrenaline that goes hand in hand with a pediatric intubation often the ETT tip can sometimes be coming out of the little guys toes after passing successfully through the vocal cords, so remember once you get it in and confirm with end-title CO2 detection (capnography or on a monitor) always remember:

Depth of insertion (cm at lip) = 3 x  normal size of ETT

Start at this depth, auscultate bilaterally in the axilla to listen for equal breath sounds, and look for equal chest rise.  If all are good then secure tube and get your chest xray. 

 

Sever's Disease

• Sever's disease is a painful inflammation of the calcaneal apophysis made worse with activity.
• It is thought to be caused by repetitive trauma to the weaker structure of the apophysis, induced by the pull of the Achilles tendon on its insertion.
• It occurs most frequently in active 10- to 12-year-old boys.
• The pain can limit performance and participation, and if left untreated, the pain can significantly limit even simple activities of daily life.
• Xrays are useful in ruling out other causes of heel pain like fracture or rare tumor but are not diagnostic or prognostic. 
• Treatment consist of rest, nsaids, wearing a half-inch inner-shoe heel lift (at all times during ambulation), a monitored stretching program, and presport and postsport icing. (rarely casting)
• Sever disease is a self-limited condition and will resolve after the growth plate fuses.

Pyloric Stenosis

• The cause of the hypertrophied pylorus muscle is unknown, but it is usually not present at birth.  Mean onset of symptoms is 2-3 weeks of life, but range can be birth to 5 months with a 4:1 male to female occurrence.
• Clasic presentation is projectile, nonbilious vomiting of last feed which may be immediate or hours later.
• Pyloric Stenosis is the most common reason for abdominal surgery in the first 6 months of life.
• Textbook lab abnormality is a Hypochloremic hypokalemic metabolic alkalosis but this is a later finding and can not be used to rule out the diagnosis.
• Ultrasonography has become the standard imaging technique for diagnosis. It is reliable, highly sensitive, highly specific, and easily performed.
• Muscle wall thickness 3 mm or greater and pyloric channel length 14 mm or greater are considered abnormal in infants younger than 30 days. 
• DDX includes :  Normal Regurgitation (all babies do it!!!), GERD, Milk Intorerance, Obstruction (antral webs, volvulus,intussusception)

PEDIATRIC FEVER + SEIZURE = FEVER

When a child has a fever and a seizure, do the age appropriate workup for a fever and you won't go wrong!!!

Routine laboratory studies usually are not indicated unless they are performed as part of a search for the source of a    fever.

Electrolytes assessments are rarely helpful in the evaluation of febrile seizures.

Patients with febrile seizures have an incidence of bacteremia similar to patients with fever alone.

 

•  Intussusception is the telescoping or prolapse of one portion of the bowel into an immediately adjacent segment.
• 90 % occur at the terminal ileum (ie, ileocolic).
• Male-to-female ratio is approximately 3:1.
• Usually seen between 5-9 months of age and 66% of all cases are in the first year of life.
• The classic triad of colicky abdominal pain, vomiting, and red currant jelly stools occurs in only 21% of cases
• Currant jelly stools are observed in only 50% of cases.
• Most patients (75%) without obviously bloody stools have stools that test positive for occult blood.
• If intussusception is strongly suspected, perform a contrast or air  enema without delay.
• Mortality with treatment is 1-3%.
• If untreated, this condition is uniformly fatal in 2-5 days.

Cardiac Involvement in Kawasaki Disease

• 50% can have Myocarditis (tachycardia, decreased ventricular function, arrhythmias, CHF, shock)
• 30% can have Pericarditis In untreated patients;
• 20 – 25% will have Coronary Artery Aneurysm during second and third week of illness Coronary Artery Aneurysms have risk of rupture, thrombosis, or stenosis
• Myocardial Infarction is leading cause of Death due to thrombosis, rupture, or stenosis of a coronary aneurysm
• Treatment with IVIG in the Acute Phase (within 10 days of onset of fever) reduces the risk of coronary artery dilation and aneurysms from 20-25% to < 5 % for coronary dilation and <1 % for giant coronary aneurysm. BUT NOT TO ZERO.

 

So the Pearl is if you have a pediatric patient with a complaint of Chest Pain, ask if there was any history of Kawasaki Disease and get an EKG ASAP if the answer is yes!

Pertussis means "violent cough". 

Think of it with prolonged coughing, inspiratory whoop, absolute lymphocytosis, or chronic cough.

Don't Use cough suppressants.

Pertussis can be a life threatening Infection!!  Especially in infants and young children.

 

 

Factors that should prompt a consideration of admitting the patient are the following:

• Age younger than 1 year
• Pneumonia
• Apneic or cyanotic spells or hypoxia
• Moderate-to-severe dehydration

 

 

Pertussis is a reportable infectious disease in the United States.

Remember to save childrens lives be aggressive with septic shock treatment early!

Do NOT allow long delays at IV attempts before moving to central lines or IOs.

        Goal in the first 0 to 15 minutes from presentation:

• Recognize decreased perfusion and mental status, maintain airway, and obtain access.
• Push 20 ml/kg of Isotonic bolus (up to and over 60 ml/kg) and reassess shock after each.*
• Correct Hypoglycemia and hypocalcemia if present. 

When community ED physicians successfully achieved shock reversal (defined by return of normal systolic blood pressure and capillary refill time) in the first 75 min from arrival there was an associated 96% survival and a > 9-fold increased odds of survival.  Each additional hour of persistent shock was associated with >2-fold increased odds of mortality.

*To push this amount of fluid in an infant or young child it may be easier to use 60 ml syringes for boluses rather than pumps

Pediatric vascular access can be a challenge especially in a critically ill child.  When placing central lines finding information on what size catheter to use and the depth of insertion can be hard to locate so here are some starters :

Age (yrs)     IJ       SC     Femoral

  0-0.5         3F       3F          3F

  0.5-2         3F       3F         3-4F

  3-6             4F      4F          4-5F

  7-12          4-5F   4-5F      5-8F

Use a single, double, or triple lumen.  (General rule more lumens the better.)

Right IJ and Right SC Depth of insertion:

If Height < 100cm    then   Initial Catheter Depth (cm) = Ht (cm)/10 -1 cm

If Height > 100 cm   then   Initial Catheter Depth (cm) = Ht (cm)/10 -2 cm

These formulas will place 98% of catheters above R atrium.

Remember in the heat and pressure of a pediatric intubation (if you don't have your Pediatic Qwic Card handy) you can estimate what size blade to use very quickly and successfully by using facial landmarks!!

• Distance from the upper incisor teeth to the angle of the jaw seems to be an excellent clinical landmark for laryngoscope blade length selection for pediatric intubations under 8 years of age 
• Take the blade (excluding the handle insertion block) and place at the upper midline incisor teeth and if the tip is located within 1 cm proximal or distal to the angle of the mandible, oral tracheal intubations are more consistently accomplished on the first attempt!!!     90% on first attempt with correct size blade v. 57% on first attempt if blade too short

And remember to start with a straight blade (Miller, Wisconsin, Guedel, Wis-Hipple etc.) for your patients under 2 years of age because:

• these blades make controlling the tounge and epiglottis easier than curved blades at this age
• and they have a smaller flange profile in the oropharynx so visualization of the vocal cords is clearer

ALTE and Infections - when to do full septic workups?

Given some recent cases of newborns with ALTEs at UMMS and Wash Co I thought I'd offer the following Pearls:   

• Overall the number of children with bacterial meningitis or bacteremia / sepsis as a cause of the ALTE is very low, much less than 1%
• However there is no data regarding the risk of meningitis in a well-appearing, afebrile infant with an ALTE

That being said THE RISK OF MISSING A SERIOUS LIFE THREATENING INFECTION is much greater than the risk of doing a complete septic workup, administering antibiotics, and admitting an infant with an ALTE.
