Gastric shake test and pharyngeal lecithin/sphingomyelin ratios were measured in newborn infants with respiratory difficulties, and in low birth weight infants in the immediate neonatal period. Both tests were useful in distinguishing infants with idioathic respiratory distress syndrome from those with respiratory difficulty due to other causes. However, in six infants with idiopathic respiratory distress syndrome, the pharyngeal lecithin/sphingomyelin ratio indicated mature lungs, and in three of these, the gastric shake test showed the presence of surfactant. Five of these six infants had been delivered by emergency lower segment caesarean section because of maternal complications, which might account for the discrepancy between the laboratory results and the clinical condition of the patient.
对患有呼吸困难的新生儿以及出生体重低的新生儿在新生儿期即刻进行了胃振荡试验和咽部卵磷脂/鞘磷脂比值测定。这两项试验对于区分特发性呼吸窘迫综合征患儿与因其他原因导致呼吸困难的患儿均有帮助。然而，在6例特发性呼吸窘迫综合征患儿中，咽部卵磷脂/鞘磷脂比值显示肺成熟，其中3例胃振荡试验显示有表面活性物质存在。这6例患儿中有5例因母亲并发症而行急诊下段剖宫产分娩，这可能是实验室检查结果与患儿临床状况之间存在差异的原因。
