Long-term ventilation for high-level tetraplegia: a report of 2 cases of noninvasive positive-pressure ventilation.

Abstract

Ventilator-dependent patients with tetraplegia rarely use noninvasive positive-pressure ventilation (NPPV) for long-term ventilation. We report 2 patients with high-level traumatic tetraplegia who were able to return home after being changed from traditional ventilation to NPPV. When they were referred to our hospital from acute care hospitals 2 to 6 months after injury, both were on tracheostomy ventilation with a cuff inflated 24 hours a day, and tidal volume (Vt) settings were low. In case 1, a man with complete C1 tetraplegia was admitted to our hospital 6 months after injury. We changed ventilator settings to high Vt and introduced NPPV. He was discharged home with NPPV with a volume-setting ventilator. Case 2 involved a man in his late twenties with complete C1 tetraplegia who was discharged home with NPPV. After discharge, he trained in glossopharyngeal breathing by himself, enabling him to breathe up to 1900mL of maximum insufflation capacity. Both have lived nearly 1 year without pulmonary complications in the community. They use visiting nurses 3 times a week and services of visiting caregivers. Further study is needed to determine the usefulness of NPPV for long-term ventilatory management.
