Medication Summary

The primary medications in treatment of dysbaric injuries are oxygen, isotonic fluids, anti-inflammatory medications, decongestants, and analgesics.

Next

Acetylsalicylic acid

Class Summary

This agent is used to control pain and inflammation and to inhibit platelet aggregation.

Aspirin (Anacin, Ascriptin, Bayer aspirin)

 

Blocks prostaglandin synthetase action, which, in turn, inhibits prostaglandin synthesis and prevents formation of platelet-aggregating thromboxane A2. By inhibiting prostaglandin synthesis, aspirin may also inhibit key steps in the inflammation process.

Decongestants

Class Summary

These agents are used to open blocked sinuses or eustachian tubes to allow for equalization of pressure.

Oxymetazoline (Afrin, Allerest)

 

Stimulates alpha-adrenergic receptors and causes vasoconstriction when applied directly to mucous membranes. Decongestion occurs without drastic changes in blood pressure, vascular redistribution, or cardiac stimulation.

Pseudoephedrine (Silfedrine, Sudafed)

 

Stimulates vasoconstriction by directly activating alpha-adrenergic receptors of the respiratory mucosa. Induces bronchial relaxation and increases heart rate and contractility by stimulating beta-adrenergic receptors.

Narcotic analgesics

Class Summary

These agents are used to treat severe pain resulting from dysbaric injuries.

Acetaminophen with codeine (Tylenol #3)

 

Indicated for the treatment of mild to moderate pain.

Previous
Next

Glucocorticoids

Class Summary

In studies of patients with spinal cord trauma, methylprednisolone has been shown to improve long-term neurologic outcome. It has not yet been approved for DCS but should be considered a treatment option.

Methylprednisolone (Solu-Medrol, Depo-Medrol)

 

By reversing increased capillary permeability and suppressing PMN activity, may decrease inflammation. May also prevent neuronal damage by inhibiting prostaglandin synthesis.

Previous
Next

Inert Gas

Class Summary

Heliox may initially accelerate bubble shrinkage when administered on the surface. Heliox may be superior to 100% oxygen for treatment at sea level.

Oxygen

 

First line of treatment in dysbaric injuries. Administer at high flow with a tight-fitting nonrebreather mask.

Helium-oxygen (heliox)

 

Consists of 50% helium and 50% oxygen.
