Reducing supplemental oxygen concentration under surgical drapes significantly lowers fire risk in ophthalmic theaters. This study demonstrates a new method to maintain therapeutic oxygen levels safely during eye surgery.

Area of Science:

  • Ophthalmology
  • Anesthesiology
  • Surgical Safety

Background:

  • High concentrations of supplemental oxygen under surgical drapes pose a significant fire hazard in ophthalmic operating theaters.
  • Existing oxygen administration methods may not adequately mitigate this risk.

Purpose of the Study:

  • To evaluate a new method for oxygen administration to eliminate fire risk during ophthalmic surgery.
  • To maintain adequate therapeutic oxygen levels while reducing potential ignition sources.

Main Methods:

  • A quasi-experimental design involving 201 ophthalmic surgery patients.
  • Comparison of a control group (100% oxygen supply) with an experimental group (24% oxygen supply) under surgical drapes.
  • Monitoring of oxygen concentration, fractional inspiratory carbon dioxide (FiCO2), peripheral oxygen saturation (SpO2), end tidal carbon dioxide (ETCO2), and respiratory rate (RR).

Main Results:

  • Significant differences in oxygen and carbon dioxide concentrations under the drapes were observed (p < .05).
  • The experimental group using 24% oxygen showed a reduction in fractional inspiratory carbon dioxide.
  • The new method effectively reduced under-drape oxygen concentrations.

Conclusions:

  • A reduced oxygen concentration (24%) under surgical drapes is effective in mitigating fire risk during ophthalmic procedures.
  • This modified oxygen administration strategy maintains patient oxygenation while enhancing operating room safety.
  • The new method is recommended for adoption in ophthalmic operating theaters to prevent fires.
