Rationale:
Diaphragmatic dysfunction is prevalent among intensive care unit patients. The use of Fu's subcutaneous needling (FSN) for respiratory problems is a new issue and few study has been conducted so far.
Patient Concerns:
Despite conventional treatments, the patient continued using noninvasive ventilation after discharge from the intensive care unit due to diaphragmatic dysfunction.
Diagnosis:
Diaphragmatic dysfunction.
Interventions:
After the myofascial trigger points were confirmed in the neck, chest, and abdomen area, FSN therapy was performed using disposable FSN needles. FSN needles were penetrated into the subcutaneous layer.
Outcomes:
The patient dyspnea and tachypnea improved, and noninvasive ventilation time dropped significantly. The patient was successfully weaned from the ventilator after 3 sessions of FSN therapy, and there was an increase in diaphragmatic excursion and tidal fraction of the diaphragm via the ultrasound imaging. We found no evidence of relapse 12 months after treatment.
Lessons:
FSN therapy has potential as an alternative strategy for patients with diaphragmatic dysfunction and severe neurologic disabilities who do not respond well to conventional therapies, but further research is still required to establish the effects of FSN on diaphragmatic function.
