    Shouldn’t I Just Give the Little Guy Some Albuterol?

    You see a 20 month old with no PMH who has been wheezing and coughing for a few days.  His cousin has RAD.  Should you just give him a little albuterol and see how he does?

    Here’s his x-ray:

    airway-foreign-body

    What are you concerned for?

    This child has evidence of aspiration with an airway foreign body, seen here with moderate hyperlucency/hyperexpansion of R hemithorax with mild deviation of mediastinum toward L chest.

    • Presentation
      • Most often (acute): sudden episode choking w/subsequent wheezing, coughing or stridor
      • Less often (delayed diagnosis): unwitnessed aspiration leading to persistent cough, wheezing, recurrent PNA/lung abscess, focal bronchiectasis or hemoptysis
    • Physical Exam
      • Often: unilateral wheezing, stridor or decreased breath sounds
        • Depending on placement of FB (i.e. intrathoracic trachea) and size of lung lobes v stethoscope head, may be symmetric
    • Imaging (usually FB is radiolucent food object so indirect findings observed):
      • PA CXR: hyperinflation or atelectasis of affected side (depending on degree of obstruction)
        • May obtain inspiratory/expiratory films if child cooperates
        • Normal XR does NOT rule out airway FB
      • Lateral decubitus CXR: failure to collapse 2/2 air trapping on affected side
      • AP/lateral soft tissue neck XR: may show infraglottic opacity and/or edema
      • Other: fluoroscopy, chest CT, MRI [focal airway edema, overinflation/air trapping, FB]
    • Treatment:
      • If in respiratory distress/unable to speak: attempt back blows/chest compressions (infants) or Heimlich maneuver (older children)
        • Otherwise, AVOID Heimlich maneuver as can dislodge FB into complete airway obstruction
      • Definitive treatment: rigid bronchoscopy
        • If unconfirmed dx, obtain flexible bronchoscopy first (can explore deeper/upper airways); may be able to remove FB, but usually requires subsequent rigid bronchoscopy
    • Disposition:
      • Once FB removed and patient stable, discharge (often same day)
        • If swelling/granulation tissue observed, corticosteroids may be administered
        • No need for antibiotics unless secretions appear infected

    Airway foreign bodies are the third most common cause of death due to unintentional injury in children younger than 1 year, so don’t forget this one!

    • renal handling of water

      If you were on a tea & toast diet, how much water would you need to drink before you develop hyponatremia? I haven’t seen anyone work out the numbers before so here are my calculations. AndRead more

    • acute acidemia physiology

      As alluded to in the first post, don’t be fooled by a “normal” potassium in the setting of DKA because osmotic diuresis and H+/K+ exchange means that total body potassium is actually LOW. You all knowRead more

    • renal handling of potassium

      the first symptom of hyperkalemia is death Earlier post covered temporizing measures to counter hyperkalemia — namely, intracellular shift, increasing cardiac myocyte threshold potential. Give furosemide if the patient still urinates and consider dialysis, but then askRead more

      Previous post reviewed the safety of balanced crystalloids in hyper K. But what was up with serum bicarbonate decreasing with saline administration? This post introduces a new way of looking at the anion gap to possiblyRead more

    • hyperkalemia and balanced crystalloids

      Is it safe to give LR or plasmalyte to a hyperkalemic patient (these balanced crystalloids have 4-5 mEq/L K as opposed to 0 mEq/L K in normal saline)? Postponing the discussion of renal handling of potassium toRead more

    • hyperkalemia physiology

      You’ll likely encounter hyperkalemia on your next Resus / Cardiac shift, and you’ll instinctively treat it. But take a moment to review the fascinating physiology behind the “cocktail”! First, consider how K+ is buffered byRead more

    • Otitis externa: use the ear wick!

      Acute otitis externa (AOE) is a common complaint seen in pediatric as well as adult emergency departments. AOE is typically not accompanied by acute otitis media, although concurrent cases are possible. Also called “swimmer’s ear”Read more
