To describe the fluoroscopic findings of swallowing in preterm infants with zero to six months of age, as well as the related diseases and clinical signs and symptoms, and to compare these findings with data obtained from full-term infants.
The retrospective findings of fluoroscopic studies carried out in infants with zero to six months of age and their respective files were analyzed. Participants were 40 subjects divided into two groups: Preterm Group, composed by 23 preterm infants, and Full-Term Group, with 17 infants born full-term.
Nasopharyngeal and gastroesophageal reflux were the main fluoroscopic findings of swallowing in both groups. There was no difference between the groups regarding the presence of swallowing disorders. The Preterm Group presented more cardiac problems than the Full-Term Group. No differences were found between the groups regarding neurologic and respiratory problems. With respect to clinical signs and symptoms suggestive of swallowing disorders, the Preterm Group presented more oxygen desaturation and the Full-Term Group, more vomiting.
Nasopharyngeal reflux and gastroesophageal reflux were the main fluoroscopic findings of swallowing in preterm infants with zero to six months of age. New follow-up studies with this population must be carried out to confirm the hypothesis that the swallowing alterations observed were due to immaturity in the swallowing function.
描述0至6个月大的早产儿吞咽的透视检查结果，以及相关疾病、临床体征和症状，并将这些结果与足月儿获得的数据进行比较。
分析对0至6个月大婴儿进行的透视研究的回顾性结果及其各自的档案。参与者为40名受试者，分为两组：早产组，由23名早产儿组成；足月儿组，有17名足月出生的婴儿。
两组吞咽的主要透视检查结果均为鼻咽反流和胃食管反流。两组在吞咽障碍的存在方面没有差异。早产组比足月儿组出现更多的心脏问题。两组在神经和呼吸问题方面没有差异。关于提示吞咽障碍的临床体征和症状，早产组出现更多的氧饱和度下降，足月儿组则出现更多的呕吐。
鼻咽反流和胃食管反流是0至6个月大早产儿吞咽的主要透视检查结果。必须对这一人群进行新的随访研究，以证实观察到的吞咽改变是由于吞咽功能不成熟这一假设。
