Good Morning! Morning Report July 3, 2012
Illness Script • Predisposing Conditions • Age, gender, preceding events (trauma, viral illness, etc), medication use, past medical history (diagnoses, surgeries, etc) • Pathophysiological Insult • What is physically happening in the body, organisms involved, etc. • Clinical Manifestations • Signs and symptoms • Labs and imaging
Predisposing Conditions • Medical history • Sickle cell • BPD • GERD • Cystic Fibrosis • Heart disease • Immunodeficiency • Increased aspiration • Neuromuscular d/o • Seizure d/o • 35-40/1000 incidence in <5yo • 7/1000 incidence in adolescents • colder months • lower socioeconomic status • smoke exposure • boys> girls
Pathophysiology • Spread by droplets • Typically follows URI • Mechanism • Colonization of nasopharynxwith further inhalation of • microorganisms, leading to a pulmonary focus of • infection • Less commonly…bacteremia results from the initial upper • airway colonization with subsequent seeding of lungs • Organisms • Streptococcus pneumonia = MOST COMMON • Others: S. aureus, Group A Strep, GNR (<3mo), anaerobes
Clinical Manifestations • Abrupt onset • High fever • Cough • Sometimes productive • Toxic appearance • Respiratory distress • Tachypnea (most sensitive/specific) • Retractions • Nasal Flaring • Grunting • Hypoxia • Chest pain
Clinical Manifestations • Focal findings on lung exam • Crackles • Diminished breath sounds • Bronchial breath sounds • Egophany • Unilateral focal infiltrate on CXR
Treatment** • Outpatient therapy (7-10days total) • First line: High dose Amoxicillin at 80-100mg/kg/day • Penicillin allergy: Cephalosporin (non-type 1); • Clinda/Azithro (type 1 allergy) • Atypical organisms: Azithromycin x 5 days • Inpatient therapy (duration varies) • Ceftriaxone or Ampicillin • More extensive disease/failed treatment • Vancomycin • Clindamycin • Azithromycin (adjunctive coverage sometime given)
Admission** • Criteria for admission • <3 months • Respiratory distress • Hypoxemia • Dehydrated • Highly febrile/toxicUnderlying disease • Testing • CBC • Blood culture • CXR • +/- Sputum culture
Complications** • Lung abscess • Thick-walled cavity with • air/fluid level • TB should be considered • Needle aspiration for culture • Necrotizing pneumonia • Rare complication of bact PNA • Liquefaction/necrosis caused by • toxins of virulent organisms • VERY ill • IV abx for at least 4 weeks
Complications** • Sterile para-pneumonic effusion • Purulent effusions with resultant empyema • Persistent fever, ill-appearing, tachypnea, increased WOB, • chest pain and splinting • Dullness to percussion/decreased air entry • CXR with decubitus, US, CT
