Although a reasonably comprehensive overview of this important topic is addressed in this edition, an effort has been made to focus more sharply on clinically applicable information. Their occurrence violates a basic principle of medical practice, primum non nocere (above all, do no harm). It is a sobering fact that adverse drug reactions are responsible for most iatrogenic illnesses. This should serve to remind physicians not to select potent and often unnecessary drugs to treat inconsequential illnesses. Many patients have come to expect drug treatments for the most trivial of symptoms. On the other hand, a physician should not deprive a patient of necessary medication for fear of a reaction. Fortunately, most adverse reactions are not severe, but the predictability of seriousness is usually not possible in the individual case or with the individual drug. An adverse drug reaction may be defined as any undesired and unintended response that occurs at doses of an appropriate drug given for the therapeutic, diagnostic, or prophylactic benefit of the patient. The reaction should appear within a reasonable time after administration of the drug. This definition excludes therapeutic failure, which the patient may perceive as an adverse drug reaction. A drug may be defined as any substance used in diagnosis, therapy, and prophylaxis of disease. Although the exact incidence of adverse drug reactions is unknown, some estimates of their magnitude are available. Reported estimates of the incidence of adverse drug reactions leading to hospitalization vary, but one study based on a computerized surveillance system determined that 2% of hospital admissions were a result of adverse drug reactions (5). As many as 15% to 30% of medical inpatients experience an adverse drug reaction ( 6). Most deaths were due to a small number of drugs that, by their nature, are known to be quite toxic. Information regarding outpatient adverse drug events is scant by comparison because most are not reported to pharmaceutical companies and appropriate national registries. Such surveys are complicated by the problem of differentiating between signs and symptoms attributable to the natural disease and those related to its treatment. Adverse drug reactions may mimic virtually every disease, including the disease being treated. The challenge of monitoring adverse drug reactions is further complicated by multiple drug prescribing and the frequent use of non prescription medications. Despite these limitations, such monitoring did identify the drug-induced skin rash that often follows ampicillin therapy. Although most drug safety information is obtained from clinical trials before drug approval, premarketing studies are narrow in scope and thus cannot uncover adverse drug reactions in all patient populations.
The occurrence of stridor or loud wheezing purchase bactroban 5 gm mastercard, heard best at the mouth purchase bactroban 5 gm with mastercard, suggests the possibility of this complication in a patient recently intubated. A potentially fatal complication of mechanical ventilation is Pseudomonas aeruginosa pneumonia or other nosocomial infection. The ventilators are often the source of infection, but the concomitant use of antibiotics and corticosteroids, 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. This has led to the recommendation that, in persistent asthma, inhaled corticosteroids should be used in conjunction with b2-adrenergic agonists.
