Pediatric Emergencies Flashcards
What is postintubation croup and when does it occur?
aka subglottic edema, usually becomes symptomatic within the first hour after extubation with maximum edema usually occurring at 4 hours after extubation and resolving by 24 hours
What are some signs and symptoms of postintubation crup?
“barking,” stridor, retractions, hypoxemia, mental status changes
What are some causes of postintubation croup?
traumatic or repeated intubations, tight fitting endotracheal tubes (air leak >25 cm H2O), high pressure/low volume cuff, prolonged intubations, surgery of the head and neck, coughing “bucking” on the tube, changing the patients position after intubation, and history of croup
What is the treatment for laryngospasm?
- remove precipitating factor
- positive pressure with 100% FiO2
- jaw thrust
- deepen the anesthetic
What is the dose of propofol for laryngospasm?
1-2 mg/kg IV
What is the dose of lidocaine for laryngospasm?
1-1.5 mg/kg IV
What is the dose of IV Succ for laryngospasm?
0.5-1 mg/kg IV
What is the dose of IM succ for laryngospasm?
4 mg/kg IM
What is the treatment for postintubation croup?
- humidified oxygen by mask adding racemic epinephrine (0.25-0.5 mL of a 2.25% solution in 3 mL of NS) administered by nebulization mask
- consider dexamethasone (0.5 mg/kg IV)
- consider prolonged observation and overnight admission
What is acute epiglottitis?
inflammation of supraglottic structures that can occur at any age
What are common pathogens for acute epiglottitis?
haemophilus influenza type B (also herpes simplex, meningococcal, streptococcus, staphylococcus, mechanical injury, and illicit drug inhalation of heated objects)
What is the presentation of a patient with acute epiglottitis?
- sore throat, fever, muffled voice, dysphagia
- rapidly increasing stridor
- rapid onset over 24 hours
- sitting, learning forward, drooling “tri-pooling”
What is the radiological “thumb sign”?
indicate of severe inflammation of the epiglottis with potential for irrevocable loss of the airway
Are laboratory tests helpful in diagnosing acute epiglottitis?
No
What is the anesthetic management of acute epiglottitis?
- direct inspection should only be performed in the operating room by the surgeon and under anesthesia with the intention to intubate
- if airway is judged to be at risk, intervention should not be delayed by attempts to attain cultures or radiographs
- strict monitored conditions int he operating room while maintaining spontaneous ventilations
- have team capable of performing immediate tracheotomy if needed
