Abstract

The authors report 9 cases of para and tetraplegia due to decompression sickness following deep sea diving. Poor technique was the cause of 8 of these cases, but one remained totally unexplained. The sequelae were serious; 3 dorsal paraplegias, which were functionally complete, 4 incomplete tetraplegias giving rise to permanent disability. In 2 cases there remained some spasticity of the lower limbs, in some cases associated with genito-urinary disorders. The authors review recent physiopathological theories. -- Blood disturbances may be due to the presence of gas bubbles which aggress the organism and give rise to coagulation disorders. -- The formation of the bubbles may be the cause of the spinal lesions, e.g. liberation in situ, gas embolism; the bubbles may form in various parts of the circulation and may cross the pulmonary barrage. Bubbles probably form in the lung itself, in the pulmonary veins and in the aorta, including the spinal capillaries. There is some slowing of the circulation, secondary to increased pressure, and pulmonary stasis may also play a harmful role. Finally, the dorsal spinal segments, which are the most poorly vascularised, are particularly exposed. This corresponds to the clinical findings. As far as treatment is concerned, the authors emphasize that recompression with hyperbaric equipment, should be carried out as an emergency, especially in unconsciuos subjects, together with other appropriate treatment. Such facts are important now that deep sea diving is becoming more and more commonly practised.
