Prevention: flu vaccine. + relief of symptoms What is the management plan for influenza? Inactivated flu vaccine - Trivalent Protects against 3 different types of flu virus (2-type A, 1 - type B) Inactivated flu vaccine - Quadrivalent Quadrivalent: Protects against 4 different types of flu virus (2-type A, 2 - type B) Inactivated flu vaccine Given by injection, approved for use in people >6 months, should not be used for those with serious allergy or reaction to previous vaccine, Guillain-Barre syndrome. Most common side effects: injection site reactions such as pain, redness, swelling Live-attenuated flu vaccine Made from weakened influenza virus, given as intranasal into both nostrils, approved for healthy people ages 2 - 49, should not be used in pregnant woman or woman who could become pregnant. Adverse effects are rare and may resemble mild flu with runny nose, nasal congestion, cough, HA doi: Can be viral or bacterial What is the etiology of sinusitis?? Nasal polyps, foreign bodies, deviated septum, or tumors obstruct mucus drainage What 𝖳 the risk of sinusitis?? Acute, subacute, recurrent acute, or chronic
anterior 90% of nosebleeds occur in the part of the nasal cavity, they are easy to visualize, can be self-treated and usually stops spontaneously Posterior bleeds occur more often in older adults with other health problems, since they are closer to the throat, it is hard to determine how much blood is lost, may require medical treatment Trauma, low humidity, URIs, allergies, sinusitis, foreign bodies, chemical irritants, overuse of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, medications or conditions that prolong bleeding time What are causes of epistaxis? Aspirin, NSAIDs, warfarin, other anticoagulant drug What medications prolong bleeding time?
Gelatin thrombin combination (Floseal) What are some examples of absorbable materials? Packable: CompresseD nasal sponges, epistaxis balloons, nasal sling arterial embolism How do you manage a posterior epistaxis? Pneumonia Acute infection of the lung parenchyma Inflammatory response = neutrophils attracted, release of inflammatory mediators, accumulation of fibrinous exudates, RBCs, bacteria → Alveoli fill with fluid+debris (consolidation)/increased production of mucus (airway obstruction) → decreased gas exchange → Resolution of infection: macrophages in alveoli ingest+remove debris, normal lung tissue restored, gas exchange returns to normal. Explain the brief pathophysiology of pneumonia CAP: Community-acquired pneumonia Acute infection of the lung in patients who have not been hospitalized or resided in long-term care facilities within 14 days of symptom onset HAP: Hospital-acquired pneumonia or nosocomial pneumonia Pneumonia in a non-intubated patient that begins 48 hours or longer after admission to hospital and was not present on admission. VAP: Ventilator-associated pneumonia A subtype of HAP, refers to pneumonia that occurs more than 48 hours after endotracheal intubation
Pneumonia chest X-ray Reveals characteristics of the infecting pathogen may also reveal pleural effusion Pneumonia bronchoscopy with bronchial washings or thoracentesis Obtains cell and fluid samples from patients not responding to initial therapy Pneumonia arterial blood gas (ABG) Reveals hypoxemia, hypercapnia, acidosis Leukocytosis Bacterial pneumonia WBC > 15 , Sputum sample for pneumonia Culture and gram stain to identify organism before starting antibiotics Blood cultures for pneumonia Done for the seriously ill with pneumonia Labs for pneumonia C-reactive protein (CRP), procalcitonin, interleukin 6 No signs of hypoxia, normal breathing pattern, clear breath sounds, normal chest x-ray, normal WBC, no complications What is the goal for pneumonia management? Supply oxygen, help perfusion, relieve obstruction, early mobilization, control infection and nutrition, relieve cough, fever, and pain with medicine What do we do for a Pt with pneumonia?
Complications: sepsis, pleural effusion, pleurisy, acute respiratory failure What do we monitor for with a Pt with pneumonia? Chronic obstructive pulmonary disease (COPD) Progressive lung disease characterized by persistent airflow limitation Chronic bronchitis Presence of cough and sputum production for at least 3 months in each of 2 consecutive years Emphysema The destruction of alveoli without fibrosis COPD Previous definitions included chronic bronchitis and emphysema. Each condition features , but neither by itself is. Smoking, infection, asthma, air pollution, occupational chemicals and dust, aging, genetics, alpha- 1 antitrypsin deficiency What are risk factors for COPD?
