Doppler bubble detection and decompression sickness: a prospective clinical trial.

Decompression sickness in human beings exposed to high ambient pressure is thought to follow from gas bubble formation and growth in the body during return to low pressure. Detection of Doppler-shifted ultrasonic reflections in major blood vessels has been promoted as a noninvasive and sensitive indicator of the imminence of decompression sickness. We have conducted a double-blind, prospective clinical trial of Doppler ultrasonic bubble detection in simulated diving using 83 men, of whom 8 were stricken and treated for the clinical disease. Diagnosis based only on the Doppler signals had no correlation with clinical diagnosis. Bubble scores were only slightly higher in the stricken group. The Doppler technique does not appear to be of diagnostic value in the absence of other clinical information.

Acute decompression sickness: 50 cases.

In a review of the most recent 50 consecutive cases of acute decompression sickness in US Navy divers undergoing training at the Naval School, Diving and Salvage, in no instance was recompression following the initial treatment necessary, nor was there any permanent morbidity post-treatment. Factors common to this series are 1) strict physical screening and conditioning; 2) physician and diver awareness of the signs and symptoms of decompression sickness; 3) short surface interval between symptom onset and recompression; 4) aggressive diagnostic and therapeutic use of hyperbaric oxygenation, and 5) judicious use of adjunctive measures such as intravenous fluid and dexamethasone (Decadron). In the ideal management, the physician sees the patient shortly after symptom appears. As soon as central nervous system involvement appears, 100% oxygen by mask is administered and the patient is recompressed supine to 60 feet of sea water.
