Good Morning MORNING REPORT JULY 23, 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 Semantic Qualifiers Symptoms Acute /subacute Chronic Localized Diffuse Single Multiple Static Progressive Constant Intermittent Single Episode Recurrent Abrupt Gradual Severe Mild Painful Nonpainful Bilious Nonbilious Sharp/Stabbing Dull/Vague Problem Characteristics Ill-appearing/ Toxic Well-appearing/ Non-toxic Localized problem Systemic problem Acquired Congenital New problem Recurrence of old problem CXR 1: LUL consolidation CXR 2: Worsening of the LUL consolidation with development of a small pleural effusion What Happens in SCD?** Autosomal recessive Chromosome 11 Glutamine Valine Polymerization of HgbS on de-oxygenation Crescent shaped RBCs Vascular occlusion Organ ischemia End-organ damage Early Diagnosis** Can be detected at birth on the NBS Early detection = better outcome Decreased bacteremia/sepsis (by 84%) PenVK started by 3 months PCV13 at 2, 4, 6mo PCV23 at 2 & 5yo ACS Predisposing Conditions Peak age 2-4 years Winter months Recurrence higher if first episode of ACS is before the age of 3yo Opioid usage (PO > IV) with preceding VOC Decreased inspiratory effort Areas of atelectasis Predisposition to development of ACS Bacteremia (in young children) Over-hydration during another illness ACS Pathophysiology Infectious (at least 30% associated with + sputum or BAL cultures) Strep pneumo (most common in younger children) Mycoplasma, chlamydia Staph aureus, Hib, Salmonella, Enterobacter Fat embolus to the lungs Arises from micro-infarction to the bone marrow If large, can be life threatening Other vascular occlusions from the sickling process COMBINATION of ABOVE ACS Clinical Manifestations Fever, cough, chest pain = most common SOB, wheeze, hemoptysis, chills Hypoxia and respiratory distress New infiltrate on CXR Upper lobe more common in children Can be multi-lobar Associated pleural effusion Hgb decreased from baseline Leukocytosis + blood cultures and/or sputum or BAL cultures 2nd leading cause of admissions after VOC** More common in children but more severe in adults Acute Chest Syndrome Acute Chest Syndrome Definition The radiologic appearance of new pulmonary infiltrate involving at least one complete lung segment plus one of the following Fever >38.5 Hypoxia Chest pain Signs of respiratory distress (tachypnea, wheezing, cough, retractions) Acute Chest Syndrome Treatment Broad spectrum antibiotics Cephalosporin (Rocephin) Macrolide (Azithromycin) +/- Vancomycin (often used here at CHNOLA) Hydration (2/3 to 3/4 MIVF) Oxygen (goal sats >92%) Incentive spirometry and CPT Bronchodilators +/- steroids If patient has a history of asthma Pain control Acute Chest Syndrome Treatment Simple transfusion Goal Hgb close to 10g/dL EARLY!! Exchange transfusion Progressive illness despite treatment Significant hypoxia Multi-lobe infiltrates Acute Chest Syndrome Importance About 50% of SCD patients experience at least 1 episode of ACS Significant morbiditiy and mortality Multiple ACS episodes may lead to Chronic, restrictive pulmonary disease Pulmonary HTN Children with recurrent episodes should be evaluated with PFTs by a pediatric pulmonologist Thanks for your attention NOON CONFERENCE: HEME/ONC EMERGENCIES DR.
