Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

5.2K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Endocarditis IV: Nursing Management

223
Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Skin Diseases and Disorders

5.0K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Endocarditis I: Introduction

283
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Fractures: Bone Repair01:27

Fractures: Bone Repair

4.6K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Summary
This summary is machine-generated.

External fixation infections in lower extremity fractures were studied. The study found no significant link between fixator duration and infection rates, suggesting other factors may be more influential.

Area of Science:

  • Orthopaedic Surgery
  • Infectious Disease Epidemiology

Background:

  • External fixation is a common treatment for severe lower extremity fractures.
  • Infections are a known complication, potentially influenced by construct type, duration, and injury severity.

Purpose of the Study:

  • To investigate the prevalence of infections in patients with external fixation for lower extremity fractures.
  • To determine if the duration of external fixation correlates with infection rates.

Main Methods:

  • Retrospective chart review of 75 patients (80 fractures) treated with temporary external fixation for lower extremity fractures.
  • Data collected included infection prevalence, fixator duration, hospitalization length, and need for fixator modification.

Main Results:

  • A significant infection rate of 28.8% (23/80 fractures) was observed at the fracture site.
  • No statistically significant association was found between the duration of external fixator application and the incidence of infection at the fracture site, pin sites, or other regions.

Conclusions:

  • While infections are common with external fixation for lower extremity fractures, the duration of fixator use does not appear to be a primary risk factor.
  • Further research is needed to identify key predictors of infection in these patients.
