Hand hygiene01:23

Hand hygiene

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.

Handwashing II: Pre-procedure and Initial Procedure Steps

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 paint...
Standard Precaution01:26

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...
Skin Diseases and Disorders01:23

Skin Diseases and Disorders

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 I: Introduction and Types of Equipment01:18

Handwashing I: Introduction and Types of Equipment

Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated.

Summary
This summary is machine-generated.

Prompt diagnosis and treatment of hand infections are crucial to prevent severe functional loss. This includes recognizing acute infections like felon and paronychia, as well as chronic infections, and differentiating them from mimics.

Area of Science:

  • Orthopedics
  • Infectious Diseases
  • Hand Surgery

Background:

  • Hand infections are frequent and can lead to significant functional impairment if not managed correctly.
  • Acute infections encompass conditions such as felon, paronychia, deep-space infections, septic arthritis, osteomyelitis, and necrotizing fasciitis.
  • Chronic infections are often attributed to atypical mycobacteria and fungi.

Purpose of the Study:

  • To emphasize the importance of accurate diagnosis and timely treatment of hand infections.
  • To highlight the need for recognizing conditions that mimic acute hand infections for appropriate management.
  • To underscore the critical role of early surgical and antibiotic interventions in preventing poor outcomes.

Main Methods:

  • Review of common acute and chronic hand infections.
  • Discussion of differential diagnoses for acute hand infections.
  • Emphasis on clinical recognition and management principles.

Main Results:

  • Identification of key acute hand infections (felon, paronychia, etc.) and chronic infections (mycobacterial, fungal).
  • Recognition of conditions that can present similarly to acute hand infections.
  • Stress on the necessity of prompt diagnostic evaluation.

Conclusions:

  • Early and accurate diagnosis of hand infections is paramount.
  • Appropriate surgical management and antibiotic therapy initiated promptly are essential.
  • Timely intervention minimizes the risk of devastating functional complications and improves patient outcomes.
