Hand hygiene

3.1K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Skin Diseases and Disorders

3.7K
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...

Handwashing II: Pre-procedure and Initial Procedure Steps

904
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

11.5K
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...

Infection01:20

Infection

7.8K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Healthcare Associated Infections II: Preventive Measures

2.6K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Area of Science:

  • Emergency Medicine
  • Infectious Diseases
  • Dermatology

Background:

  • Dog bites pose a risk of infection, including cellulitis.
  • Proper wound care is essential but may not prevent all complications.
  • Rabies and tetanus are significant concerns following animal bites.

Observation:

  • A 27-year-old man presented with a swollen, red wound after a stray dog bite.
  • Initial self-cleaning of the wound did not prevent secondary infection.
  • The patient sought medical attention due to worsening signs of cellulitis.

Findings:

  • Management of the patient's cellulitis was initiated.
  • Prophylaxis for rabies was administered.
  • Tetanus prophylaxis was updated.

Implications:

  • Highlights the importance of seeking medical evaluation for seemingly minor bite wounds.
  • Underscores the necessity of timely antibiotic treatment for cellulitis.
  • Reinforces the critical role of post-exposure prophylaxis for rabies and tetanus in bite victims.
