The authors managed 10 patients with Duchenne muscular dystrophy (DMD) and five with MG with pressure-controlled ventilation (PCV) via mini-tracheostomy tube (MTT). The arterial partial pressure of CO2 (PaCO2) of the patients with DMD decreased after conversion to PCV via MTT from biphasic positive airway pressure (BIPAP) or a body ventilator. The MG patients could be converted from conventional volume-controlled ventilation to PCV via MTT. PCV via MTT achieves more effective ventilation than either BIPAP or a body ventilator and is as effective as ventilation via a conventional tracheal tube. |
