CYSTIC FIBROSIS LAUREN BURNETT NUR3215 EBP OBJECTIVES By completion of this presentation, learners should be able to: • Describe the effects Cystic Fibrosis has on the body • Generate a nursing plan for patients with Cystic Fibrosis • Differentiate between different manifestations of cystic fibrosis • Compare and contrast between different treatment options for Cystic Fibrosis WHAT IS IT? • A genetic disorder of the exocrine glands that results from defective sodium and chloride transport • Primarily affects respiratory system and GI tract EPIDEMIOLOGY • • • • • • 30,000 people in the US 70,000 people worldwide 100 new cases a year Median age of diagnosis – 6 months Median age of survival – mid 30’s Primarily affects Caucasians ETIOLOGY • Mutation in the Cystic Fibrosis Transmembrane Conductive Regulator (CFTR) gene • CFTR gene is responsible for production of a protein that regulates how salt and water are carried across membranes PATHOPHYSIOLOGY • • • • Alteration in chloride, salt, and water transport Goblet cells increase in size and number Mucus becomes excessively thick and sticky Mucus clogs the airways (and other organ systems) PATHOPHYSIOLOGY • Bacteria grow inside mucus • WBC responds to infection, further aggravating airway • Frequent, persistent infections occur, damaging the lungs • Respiratory failure and possible death MANIFESTATIONS • Respiratory manifestations are most common • • • • • • • • Persistent cough (maybe with purulent, green sputum) Multiple respiratory infections Possible wheezing Bronchiectasis Hemoptysis Tachypnea Shortness of breath Loss of appetite/weight loss SYSTEMIC MANIFESTATIONS • Gastrointestinal • Cramps, pain, pancreatic abnormalities • Endocrine • Glucose intolerance, polydipsia, polyphasia, polyuria • Reproductive • Male sterility, pregnancy complications, delayed sexual development DIAGNOSIS • Newborn testing – heel stick • Based on clinical symptoms • Verified by diagnostic tests • • • • Sweat Chloride test CXR Pancreatic enzymes DNA analysis to detect CFTR gene mutation HYPERINFLATION WITH BRONCHIECTASIS MANAGEMENT • Overall goal – • • • • • Control/prevent infection Maintain clear airways Improve nutrition Psychosocial support Improve quality of life • There is NO cure to treat all patients at this time • Early detection and diagnosis is crucial to delay progression NURSING MANAGEMENT • Assessment – • History, symptoms, activity, nutrition intake, medication use • Diagnosis – • • • • Ineffective airway clearance Ineffective breathing pattern Risk for infection Imbalanced nutrition • Goals of Care – • Maintain adequate airway • Reducing risk factors for infection • Patient Education MANAGEMENT • • • • Prophylaxis against infection Early antibiotic therapy when symptoms arise Chest physiotherapy Surgery • Removal of nasal polyps • Lung lobectomy • Lung transplant • • • • Bronchodilators Tobramycin Azithromycin DNase IS THERE A CURE? • Ivacaftor (Kalydeco) A CFTR potentiator FDA approved for treatment of CF Only for 1 mutation type (there are over 1,500) Reduces viscosity of mucus Improves respiratory function and reduces risk of exacerbations • Significant reduction in sweat chloride test • 10 adverse effects on label • • • • • DRY POWDER TOBRAMYCIN Aminoglycoside antibiotic used for years as a nebulizer Very effective against Pseudomonas aeruginosa Now available as a dry powder to be inhaled (TIP) Before TIP (inhaled version), nebulizers were only option due to high dosage required • Higher incidence of cough • Faster administration time, more convenient and portable • Greater patient satisfaction than nebulizer treatments • • • • SO WHAT? • • • • Patient Education TB screening Immunizations Advocate for the patient NCLEX QUESTION A patient comes into the ER complaining of a chronic cough. Upon assessment, the nurse learns this patient has a history of CF and is also experiencing shortness of breath . Which manifestation of CF should the nurse suspect? A. Respiratory infection B. Hemoptysis C. Bronchiectasis D. Emerging nasal polyps NCLEX QUESTION A patient comes into the ER complaining of a chronic cough.
