Weaning from long-term mechanical ventilation utilizing closed-loop ventilation mode (IntelliVent ® -ASV ® ) in a patient with spinal cord injury.
INTRODUCTION: Cervical spinal cord injury with the C3 neurological level may cause respiratory failure and require long-term mechanical ventilation. Conventional weaning of spontaneous breathing trials is difficult to perform outside of intensive care or spinal cord units.
CASE PRESENTATION: An 80-year-old man presented with total tetraplegia and restrictive respiratory failure that required assisted ventilation after a falling accident. Cervical spine magnetic resonance imaging showed cervical cord compression that was worst at the C3-C4 intervertebral level. He experienced unexpected cardiac arrest during the conventional weaning process of trials of intermittent spontaneous breathing in the intensive care unit. The automated weaning protocol utilizing a closed-loop ventilation mode (IntelliVent® -ASV ® ) was introduced 131 days after injury in our ward for chronically ill patients. The patient was successfully weaned 39 days after the introduction of the weaning protocol.
DISCUSSION: An automated weaning protocol utilizing a closed-loop ventilation mode could be an optional procedure in patients with cervical cord injury on long-term mechanical ventilation, even in a ward for chronically ill patients where sufficient staff is not available. The efficacy and safety, and the cost-effectiveness of the procedure should be examined in larger spinal cord units.
