A potentially fatal complication of mechanical ventilation is Pseudomonas aeruginosa pneumonia or other nosocomial infection clomid 25mg with visa. The ventilators are often the source of infection generic clomid 25mg on line, but the concomitant use of antibiotics and corticosteroids generic clomid 100mg with mastercard, along with an impaired bronchopulmonary defense mechanism, are important predisposing factors. The radiologic picture of this type of pneumonia is variable and may consist of bilateral or unilateral consolidation, nodular lesions, or abscess formation. The diagnosis is established by repeated cultures from tracheal and bronchial secretions, and specific antibiotic therapy is best determined by sensitivity studies. Prolonged use of neuromuscular-blocking drugs combined with corticosteroids can cause severe myopathy that requires rehabilitation measures. If the patient is a corticosteroid-dependent asthmatic patient currently on a maintenance dose of prednisone, increase the dose of prednisone instead of relying on increased use of bronchodilators or inhaled corticosteroids to ensure complete control of asthma. If the patient is dependent on inhaled corticosteroids, a short course (4 to 5 days) of prednisone (25 to 40 mg/day) before surgery is recommended to maximize pulmonary function. The main need for corticosteroids, however, is prevention of intraoperative or postoperative asthma rather than adrenal crisis. Hydrocortisone, 100 mg intravenously, should be started before surgery and continued every 8 hours until the patient can tolerate oral or inhaled medications ( 296). The doses of prednisone and hydrocortisone needed to control asthma do not increase postoperative complications, such as wound infection or dehiscence ( 296). In patients with asthma, optimal respiratory status should be achieved before surgery occurs. Aerosol bronchodilators, deep-breathing exercises, adequate hydration, and gentle coughing should be instituted to avoid accumulation of secretions and atelectasis. Use of epidural or spinal anesthesia is not necessarily safer than general anesthesia ( 297). These complications are thought to result from the rupture of overdistended peripheral alveoli. The escaping air then follows and dissects through bronchovascular sheaths of the lung parenchyma. When severe tension symptoms occur, insertion of a chest tube under a water seal for pneumothorax may be needed. Tracheostomy may be required for severe tension complications of pneumomediastinum. A common feature of these conditions is chest pain; this is not expected with uncomplicated asthma, and when present should suggest the possibility of the extravasation of air. On auscultation of the heart, a crunching sound synchronous with the heartbeat may be present with pneumomediastinum (Hamman sign). It is often reversible with bronchodilators and prednisone, given immediately to avoid the risk of bronchoscopy, or at least to prepare for this examination. When the atelectasis does not respond to the above treatment within a few days, bronchoscopy is indicated for both therapeutic and diagnostic reasons. Occasionally, children may develop atelectasis of other lobes or of an entire lung. Rib fracture and costochondritis may occur as a result of coughing during attacks of asthma. These conditions occur with irreversible destruction of lung tissue, whereas asthma is at least a partially to completely reversible inflammatory condition. The identification of bronchiectasis in a patient with asthma should raise the possibility of allergic bronchopulmonary aspergillosis, undiagnosed cystic fibrosis, or hypogammaglobulinemia. Hypoxemia from uncontrolled asthma has been associated with adverse effects on other organs, such as myocardial ischemia or infarction. Although this effect typically produces no clinical ramifications, in the exceptional patient, irreversible asthma occurs ( 141). Most of these patients do not have steroid-resistant asthma because they have more than 15% bronchodilator response to 2 weeks of daily prednisone. The increase in mortality rate from asthma that occurred in the 1980s in the United States appeared to stabilize by 1996 but has not declined ( 298). The use of repeated doses of b2-adrenergic aerosols has been suspected to be a contributing factor in some of these deaths but is unlikely to be a satisfactory explanation. Fatality rates are lower in the United States and Canada than in many countries, including as New Zealand and Australia. A 1980s surge in deaths in New Zealand and the availability of albuterol inhalers without prescription in that country has been considered possibly analogous to the earlier epidemics of the 1960s. Undue reliance on inhaled b 2-adrenergic agonists by patients and physicians may contribute to fatalities in patients with severe exacerbations of asthma because essential corticosteroid therapy is not being administered. In addition, excessive deaths associated with the potent b 2-adrenergic agonist fenoterol have been reported.
