Septic shock

infections no longer respond to common antibiotics. Boils, impetigo, cellulitis, and staphylococcal scalded skin syndrome, are examples of skin infections caused by staphylococcus. Staph bacteria can also cause food poisoning, bacteremia, toxic shock syndrome, and septic arthritis (Mayo Clinic, 2014 June…

A 42-year-old male is admitted to the ICU for septic shock and hypotension. Vital signs include heart rate of 115 beats/min, respiratory rate 22 breaths/min, blood pressure of 82/40 mmHg, and oxygen saturation of 88% on 2L nasal cannula. A vasopressor is needed to address this patient’s hypotension. Prior to placement of an arterial line at the radial artery, which of the following describes the most appropriate diagnostic test? A. Instruct the patient to flex the elbow to 90 degrees while the…

year old woman with a history of chronic venous stasis and chronic non-healing leg wound. She went to the Emergency Room (December 27, 2013) complaining of bilateral lower extremity swelling (cellulitis) and pain. She had a severe infection (septic shock), was admitted to the hospital, was seriously ill, and “ended-up with bilateral above-knee amputation.” She developed multiple problems, including kidney failure (required dialysis), and cardiac problems (atrial fibrillation). She had a…

nodes. Scarlet fever, as well as impetigo, and pneumonia are also caused by this bacterium. The less common infections consist of septicaemia, mastitis, endocarditis, sepsis, cellulitis, meningitis, erysipelas, myositis, otitis media, osteomyelitis, septic arthritis, pericarditis, and neonatal. a. S. pyogenes on blood agar b. S. pyogenes with Pappenheim stain S. pyogenes grows in streptococcus…

(hypotension) and capillary refill of 4 seconds, extremities cool, clammy and molted, bilateral ankle edema and 3rd heart sound present. Documentation of carotid pulse presence but the absence of radial pulse, the patient may be experiencing cardiogenic shock. Here the poor contractibility of cardiac muscle causes stoke volume (SV) and cardiac output (CO) to decline (Elliott, Aitken & Chaboyer, 2015). Secondly the compensatory mechanism triggers renin-angiotensin-aldosterone system (RAAS) which…

One of the leading causes of bacterial meningitis is Neisseria meningitidis, which can be acquired globally. N. meningitidis is normal flora in the human nasopharynx, but if an individual becomes susceptible, it can lead to bacterial meningitis. Incidence of N. meningitidis is strongly influenced by age. Infants have the highest risk for meningococcal disease. Low serum bactericidal antibody levels play a large role in those that are at risk for infection. Those with compromised immune…

Bacillus anthracis is the causative organism of the serious infectious disease, called anthrax. There are three manifestations of this disease. The manifestations include gastrointestinal anthrax, inhalation anthrax, and cutaneous anthrax. This research will explore the morphology, virulence factors, reservoir, transmission, and portal of entry of B. anthracis. The pathogenesis will also be reviewed, including symptoms, how B. anthracis causes these symptoms, the possible complications of the…

N. meningitidis is the cause of meningococcal meningitis infections that have a…

with acute respiratory distress syndrome: as many as 50% of children diagnosed with this condition will die From it8 URGENT ACTION • Acute presentation of acute respiratory distress syndrome in children (i.e., tachycardia, tachypnea, hypotention and shock) requires quick evaluation and initiation of a complex treatment plan involving hospitalist, intensivist, pulmonologist and pediatrician collaboratively rendering care that is in harmony with the goals of treatment (i.e., ventilation,…
