Burn Injuries

2.6K
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...

Summary

A new grading system, E-PIX, enhances assessment of acute ocular chemical injuries by including epithelial defects, intraocular pressure, ischemia, and exposure. This system aims to improve patient outcomes by ensuring comprehensive evaluation and management of vision-threatening factors.

Area of Science:

  • Ophthalmology
  • Trauma Care

Background:

  • Acute ocular chemical injuries pose significant risks to vision.
  • Current grading systems may not fully capture all factors influencing outcomes.

Purpose of the Study:

  • To introduce E-PIX, an enhanced grading system for acute ocular chemical injuries.
  • To incorporate key factors like epithelial defect, intraocular pressure, ischemia, and exposure into a unified system.

Main Methods:

  • Development of an online and manual grading system named E-PIX.
  • Inclusion of parameters: epithelial defect (E), intraocular pressure (P), scleral ischemia (I), and exposure (X).
  • Grading of epithelial defect includes limbus, conjunctiva, cornea, and tarsus.

Main Results:

  • E-PIX provides a comprehensive annotation of injury factors.
  • The system aids in assessing and addressing vision-threatening complications.
  • Prognostication is enhanced by considering additional factors beyond limbal involvement.

Conclusions:

  • The E-PIX system offers a uniform and comprehensive approach to grading ocular chemical injuries.
  • It facilitates better assessment, management, and prognostication for improved patient outcomes.
  • The system is designed for accessibility to primary and tertiary caregivers.
