Primary Raynaud's phenomenon in premature infant: a case report

Abstract

This is a case report of preterm female neonate with Raynaud's phenomenon, who was born at 30+3 weeks of gestation. Her right upper limb completely turned pale from wrist to fingers with undetermined cause five days after birth, with weakened radial artery pulsation and lower skin temperature than the other side. After several treatment steps including right upper limb massage, keeping warm, intravenous infusion of Alprostadil and application of tropical mucopolysaccharide polysulfate cream, the affected limb gradually turned to purple and then ruddy. No abnormality was detected in the examinations for secondary Raynaud's phenomenon, therefore a primary Raynaud's phenomenon was considered. No similar symptoms recurred during hospitalization or follow-ups. Though rare, Raynaud's phenomenon should be considered if patients' hands suddenly turn to pale and then purple. The main treatments involve removing the causative factors, keeping warm and massage of the affected limb. Medications can be used to improve peripheral circulation if necessary. Long-term follow-up is needed for neonates suffered from Raynaud's phenomenon. Key words: Raynaud's phenomenon; Infant, premature; Treatment
