Abstract

Two patients with respiratory paralysis by cervical(C) injury were treated by sequential four-pole stimulation of the phrenic nerves to pace the diaphragm. With sequential four-pole nerve stimulator, full-time bilateral electroventi-lation were achieved and the conditioning of the diaphragm have been performed in 72 hours. According to other papers using unipolar or bipolar electrode, conditioning of the hypotrophic diaphragm took 2 to 1l months, and full-time electroventilation was possible in only about half of the patients, so part-time mechanical ventilation was needed in remained half of the patients. These results suggest that the conditioning time in patients with high quadriplegia could be significantly shortened and it should be possible to achieved independence from the mechani-cal ventilator when sequential four-pole stimulator was used.
