Respiratory flutter syndrome in a neonate.

Respiratory flutter or diaphragmatic flutter is a rare disorder characterized by involuntary, high frequency contractions of the diaphragm. Only 7 cases are reported in infants till date. The present case presented with life threatening respiratory distress immediately after birth. In view of high respiratory rate of 120-154 per minute, clinical and fluoroscopic evidence of diaphragmatic contraction and absence of any obvious CNS, cardiovascular and respiratory pathology, respiratory flutter was diagnosed. It was also associated with dysphagia and laryngomalacia. The patient was managed with prolonged continuous positive airway pressures (CPAP) with partial success, but symptoms improved with use of chlorpromazine.
