미숙아에서 호흡곤란 증후군의 조기예견을 위한 Shake test와 Stable Microbubble Rating Test 의 의의

Abstract

Respiratory distress syndrome (RDS) of newborn is a disease revealed high morbidity and mortality rate, especially in premature infant. To evaluate the predictive value of Stable Microbubble Rating (SMR) and Shake test on RDS in premature infant, the anthors carried out the gastric aspirates Shake test and SMR test at birth, 3 and 6 hours after birth respectively on 124 premature infants who were born at the department of Pediatrics, Dong-San Hospital, Keimyung University during the period of 6 months from June 1993 to November 1993. The following results were obtained 1) Among the 124 premature infants, RDS was developed on 23 (18.5%). 2) The birth weight, gestational age and Apgar score were significantly lowered in RDS cases than non-RDS cases (p<0.005). 3) The sensitivity, specificty, postive-and negative-predictive values of Shake test were 87.0%, 79.2%, 48.8% and 96.4% and those of SMR test were 100%, 93.1%, 76.7%, 100% at birth, 95.7%, 88.1%, 64.7%, 98.9% at 3rd-hour of life, and 95.7%, 72.3%, 44%, 98.6% at 6th-hour of life. With the results of this study we concluded that SMR tests at birth and 3rd-hour of life were more useful in predicting the incidence of RDS than shake test or SMR test at 6th-hour of life.
