Tx for FB removal

A

Attempt removal with back blows and chest compressions in infants, heimlich maneuver in older children. Intubate until bronchoscopy can be performed. Nebulizers and chest physiotherapy after removal.

21
Q

Causes of bronchiolitis

A

RSV, rhinovirus

22
Q

Population most often affected with bronchiolitis

A

Infants less than age 2

23
Q

1 year old child presents to you in January with symptoms of nasal congestion and cough. He has a fever and cough, with associated otitis media. Auscultation shows wheezing upon exhalation and fine and coarse crackles. Hyperresonant percussion sounds, and hyperexpanded chest. You notice nasal flaring and grunting. Tachypnea is present. Child looks dehydrated. What is the diagnosis?

A

Bronchiolitis- inflammation of the smaller airways. Common in kids less than 2, often in winter months

24
Q

Diagnosis of Bronchiolitis

A

Usually done clinically. can order CBC and CXR in more severe cases

25
Q

Tx of Bronchiolitis

A

Admit if hypoxemia, cyanosis, dehydrated, lethargy. Otherwise, trial of inhaled bronchodilators.

26
Q

Complications of bronchiolitis

A

bronchiolitis obliterans, asthma, secondary bacterial infection, apnea, respiratory failure

27
Q

RSV Infection - risk factors

A

Infants less than 6 months, infants born less than 35 week gestation, chronic lung dz or congestive heart dz in kids, innunocompromised, if live at high altitude

28
Q

Define RSV infection

A

Virus that causes upper respiratory tract infection, 20-30% of patients will also develop lower respiratory infection (more common in infants/young kids than older children/adults

29
Q

How is RSV spread

A

Direct contact and aerosol droplets

30
Q

It’s January, and a 1 year old child presents to you with rhinitis, sinusitis, nasal congestion, sore throat. Mother says child has not been feeding well and has periods of apnea. Child has fever and looks lethargic. You hear wheezes and crackles, and prolonged expiration. You can feel the spleen and liver on abdominal exam d/t hyperinflation of lungs. Dehydration present. Tachypnea present. What is the diagnosis

A

infant presents with both upper and lower respiratory tract symptoms. Child is young and it’s winter season. Influenza vaccine taken. RSV infection confirmed by throat and nasopharyngeal swab

31
Q

Diagnosis of RSV infection

A

Analysis of respiratory secretions through nasal wash, nasopharyngeal swab, or throat culture. Rapid antigen assay, PCR assay also available.

32
Q

Tx for RSV infection

A

Supportive care, beta-agonist therapy if lower airway obstruction to open up bronchioles, DON’T use corticosteroids, ribavirin only used if at risk for severe lower respiratory infection

33
Q

Most likely to see viral laryngotracheitis?

A

Children 6 months- 3 years

34
Q

Cause of viral laryngotracheitis

A

Parainfluenza virus type 1

35
Q

3 year old child presents with fever and nasal congestion and coryza x 4 days. You notice respiratory distress, and hoarseness, barking cough, and inspiratory stridor. There is a prolonged inspiratory phase. Appears dehydrated with mild tachypnea. How would you diagnose this?

A

Suspect viral laryngotracheitis. Often clinical diagnosis- Xray may show “steeple sign” which demonstrates subglottic narrowing

36
Q

Tx for viral laryngotracheitis

A

Supportive care, single dose of systemic corticosteroids, nebulized epinephrine (bronchodilator)

37
Q

Cause of bacterial tracheitis?

A

Staph or strep

38
Q

Presentation of bacterial tracheitis

A

Initial symptoms similar to viral, with nasal congestion and coryza, but appear more toxic.

39
Q

Diagnostic evaluation of bacterial trachetis

A

Leukocytosis, Xrays reveal severe subglottic and tracheal narrowing

40
Q

Tx for bacterial tracheitis?

A

Supportive care, hospitaliztaion, IV abx

41
Q

Mother complains of son waking up at night with severe barking cough and inspiratory stridor, and hoarseness. This only happens during the night and duration is short. What is the diagnosis and how to treat?

A

Spasmodic or frequent recurrent croup- comfort anxious child and administer humidified air

42
Q

Phases of pertussis

A

Catarrhal, paroxysmal, convalescent

43
Q

Catarrhal phase

A

Nonspecific, 1-2 weeks

44
Q

Paroxysmal

A

Persistent coughing attacks lasting 2-6 weeks

45
Q

Convalescent

A

Cough decreases over several weeks to months

46
Q

Mode of transmission of pertussis

A

Direct contact- most contagious during catarrhal stage and first 2 weeks of paroxysmal stage

47
Q

Incubation period for pertussis

A

Takes 7-10 days for symptoms to show

48
Q

In what kind of people will you see atypical presentation of pertussis?

A

Vaccinated individuals who get infected, and children

49
Q

Child presents with whooping cough. Nasopharyngeal and throat cultures are positive for bordatella pertussis. CBC reveals leukocytosis and lymphocytosis. What is the next step of action?

A

Report pertussis to public health authorities, supportive care. Begin abx therapy if caught early in catarrhal stage- macrolides x 7-14 days. May use bronchodilator therapy, avoid antitussives and opioid cough suppressants- little effect. Child can return to school after 5 days of abx therapy.

50
Q

Pertussis prevention

A

Vaccination with DTaP or Tdap. Abx prophylaxis for individuals in close contact of infected individuals- macrolides

51
Q

2 year old child appears with fever, cough, malaise. PE reveals tachypnea, emesis, decreased breath sounds, bronchial breath sounds, crackles, wheezes, egophony, bronchophony, tactile fremitus increased, dullness to percussion. Also hypoxemic. Very fussy restless, and not feeding well. Diagnosis and tx.

A

CBC, acute phase reactants. Serum electrolytes for dehydration. Blood and sputum, nasopharyngeal swabs. CXR not needed, but because child is less than 4 years old, use AP view. (PA for above 4).

52
Q

Pneumonia causes in kids

A

Neonatal 1-30 days: Group B strep. Less than 5 years, viral more common- measles, varicella, HSV. More than 5 years- Strep, M pneumonia, chlamydophilia
