No ignition risk with hyperbaric enflurane
Anaesthesia and Intensive Care
|May 1, 1978
Summary
Enflurane gas mixtures are not explosive under hyperbaric conditions. Experiments confirmed no detonation risk with Enflurane up to 5% in oxygen or nitrous oxide at 3 atmospheres absolute.
Area of Science:
- Anesthesiology and Hyperbaric Medicine
Background:
- Anesthetic agents require safety assessments under diverse physiological conditions.
- Hyperbaric environments necessitate evaluation of gas mixture flammability.
Purpose of the Study:
- To assess the explosive potential of Enflurane under hyperbaric conditions.
- To determine safety limits for Enflurane use in hyperbaric oxygen therapy or anesthesia.
Main Methods:
- Experiments were conducted using Enflurane.
- Gas mixtures of Enflurane with oxygen and nitrous oxide were tested.
- Hyperbaric conditions up to 3 atmospheres absolute (A.T.A.) were applied.
Main Results:
- No explosive or detonation risk was observed.
- Enflurane concentrations up to 5% in oxygen or nitrous oxide were tested.
- Safety was maintained under hyperbaric stress up to 3 A.T.A.
Conclusions:
- Enflurane demonstrates a lack of explosive risk in oxygen and nitrous oxide mixtures.
- The study supports the safe use of Enflurane within tested hyperbaric parameters.
- Findings are crucial for anesthetic safety protocols in hyperbaric settings.
