Burn Injuries01:22

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
Healing II: Complications01:24

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Handwashing III: During the Procedure and Post-Procedure Steps

To wash hands properly, follow these steps:
Handwashing II: Pre-procedure and Initial Procedure Steps01:19

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...
Secondary Spinal Cord Injury llI: Pathophysiology01:25

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
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.

Summary
This summary is machine-generated.

Hand burns frequently cause significant functional impairments like retractions and amputations. Treatment requires patient involvement due to its long and complex nature.

Area of Science:

  • Reconstructive surgery
  • Burn management
  • Hand surgery

Context:

  • Hand burns are a common and serious injury.
  • Aesthetic and functional outcomes are often compromised.
  • Understanding the distinct properties of palmar and dorsal hand skin is crucial for treatment.

Purpose:

  • To outline the aesthetic and functional sequelae of hand burns.
  • To describe treatment strategies for common complications like nail and digital/wrist retractions.
  • To highlight specific challenges in managing electrical burns and pediatric burn cases.

Summary:

  • Hand burns result in varied aesthetic issues, such as proximal nail retractions requiring skin grafting.
  • Functional deficits include digital and wrist retractions, often treated with scar excision and collagen substitutes, and commissure retractions managed with trident plasty.
  • Specific cases like electrical burns leading to amputation (treated with index policization) and pediatric burns with growth-related contractures necessitate long-term management.

Impact:

  • Effective management of hand burn sequelae is essential for restoring hand function and appearance.
  • The use of collagen substitutes and specific surgical techniques like trident plasty can improve outcomes.
  • Long-term patient engagement is critical due to the complex and prolonged nature of recovery from hand burns.
