Background. Diaphragm pacing with electrical stimulation of the phrenic nerve is an established treatment for central hypoventilation syndrome. The device, however, is not readily available, at least, in Japan. We applied the spinal cord stimulator for pain control to phrenic nerve stimulation. The purpose of this study is to evaluate the efficacy and feasibility of phrenic pacing with the compromise method. Method and patients. We implanted a spinal cord stimulator in five patients with chronic central hypoventilation. The stimulation electrode was placed along the phrenic nerve in the neck, and the device was implanted in the anterior chest. We used the cyclic mode, and set the parameters at 1 second ramp up, 2 seconds on, 3 seconds off. The pulse width and the frequency were set at 150 μsee and 21 Hz respectively. The amplitude was adjusted to obtain sufficient tidal volume and to maintain PaCO2 at around 40 mmHg. Findings. During the follow-up period from 3 to 34 months (mean 23), stable and sufficient ventilation were observed in all patients without complications. Interpretation. Although longer follow-up is necessary, diaphragm pacing with the spinal cord stimulator is feasible for treatment of central hypoventilation syndrome. © Springer-Verlag 2003.
