The presence of fever should prompt the clinician to analyze its height ampicillin 250mg line, frequency purchase 500mg ampicillin, pattern, and associated history, physical findings, and laboratory tests to determine the cause of fever and appropriate treatment (1,4,5,27,42–44,53). Fever, per se, should not be treated unless the fever itself is a threat to the patient, i. Temperatures >1028F in patients with severe cardiac/pulmonary diseases could precipitate acute myocardial infarction or respiratory failure (5,58). Fever is also an important host defense mechanism that should not be suppressed without a compelling clinical rationale (58–60).

The ability to rapidly identify the cause of fever and rash in critically ill patients is essential for the proper management of the patient and protection of the health care worker(s) providing care for that patient. A rapid method to narrow the potential life-threatening causes of fever and rash has been described by Cunha (1). The traditional approach to the patient with fever and rash is based on the characteristic appearance of the rash (2,3). The most common types of rash include petechial, maculopapular, vesicular, erythematous, and nodular. Although there can be overlap in presentation, most causes of fever and rash can be grouped into one specific form of cutaneous eruption (3). A systematic approach requires a thorough history that includes patient age, seasonality, travel, geography, immunizations, childhood illnesses, sick contacts, medications, and the immune status of the host. A detailed history, physical exam, and characterization of the rash will help the clinician reduce the number of possible etiologies. Appropriate laboratory testing will also assist in delineating the cause of fever and rash in the critically ill patient. History A comprehensive history of the events leading up to the development of fever and rash is essential in the determination of the etiology of the illness. Several initial questions should be answered before taking a complete history (4,5). For example, patients with meningitis due to Neisseria meningitidis will need droplet precautions, while patients with Varicella infections will need airborne and contact precautions (Table 2). Gloves should be worn during the examination of the skin whenever an infectious etiology is considered. Are the skin lesions suggestive of a disease process that requires immediate antibiotic therapy? After the preliminary evaluation of the patient, the physician can obtain more information, including history of present illness and previous medical, social, and family histories. Specific questions about the history of the rash itself are often helpful in determining its etiology (Table 3). Such questions should include time of onset, site of onset, change in appearance of the lesions, symptoms associated with the rash (i. The physical exam should focus on the patient’s vital signs, general appearance, and the assessment of lymphadenopathy, nuchal rigidity, neurological dysfunction, hepatomegaly, splenomegaly, arthritis, and mucous membrane lesions (Table 4) (3,4). Skin examination to determine type of the rash (Table 5) includes evaluation of distribution pattern, arrangement, and configuration of lesions. The remainder of this chapter will provide a diagnostic approach to patients with fever and rash based on the characteristics of the rash. Several clinically relevant causes of each type of rash associated with fever are described in brief. Purpura or ecchymoses are lesions that are larger than 3 mm and often form when petechiae coalesce. Infections associated with diffuse petechiae are generally amongst the most life threatening and require urgent evaluation and management. There are many infectious causes of these lesions (Table 6); several of the most dangerous include meningococcemia, rickettsial infection, and bacteremia (1,3,8).

Infection control is especially important within healthcare settings, where the risk of infection to patients is greatly increased. Good infection control techniques adopted during patient care can assist greatly in preventing or reducing avoidable History of infection control Infection control measures help hospital-acquired infections. In the 14th century, the Venetians quarantined ships arriving at their port in order to contain diseases There are important public health issues in the prevention and control such as plague. In the 19th of infection, including the general health and nutritional status of the century, Semmelweiss, a Viennese obstetrician, realized that infection public, and their living conditions, such as housing, water and sanitation was passed to patients on the hands of healthcare workers. These influence the level of infectious disease in the community, showed conclusively that infection could be greatly reduced by hand which in turn affects the level of infection of those both in and outside washing. In addition, in the 19th century separate facilities for of hospitals, thus affecting the burden on healthcare facilities. Local infection control policy manuals should be produced within Basic infection control measures individual settings in order to give guidance to staff on the are essential in everyday practice today. The introduction of antibiotics in Hospital-acquired the 1940s saw a decrease in basic measures, such as cleaning, in (nosocomial) infections everyday hospital practice, which Hospital-acquired infections, or nosocomial infections, are infections that previously had been the only defence measure for patients were not present or incubating on admission of a patient to hospital. People thought These infections can be readily diagnosed in patients who have appeared that the microorganisms that had caused many deaths had been free of signs and symptoms of infection on admission and have then gone beaten. Unfortunately it was soon discovered that these micro- on to develop infection – for example, a surgical wound exuding pus. In addition, they were These infections can cause unnecessary suffering for the patient and also able to inactivate antibiotics by developing chemicals that rendered create unnecessary costs for the health facility. Page 4 Module 1 Microbiology To begin to understand why we must undertake infection control measures we must first consider aspects of microbiology. Microbiology is broadly described as the study of bacteria, fungi, protozoa, viruses, and helminths. In studying these groups of organisms, including their are small microorganisms of simple primitive form. Bacteria many subgroups and families, we can learn how: can commonly be found living • they live within us; within our bodies and in our environment, for example in • they live in our environment; animals, soil and water. For examples of common agents so small that they are microorganisms found in healthcare settings, see Appendix 1. Knowledge of Fungi are simple plants that are parasitic on other plants and this cycle is essential in order to understand how infection can occur.
