Abstract

Respiratory distress syndrome of preterm infants remains a significant cause of morbidity and mortality. Early, just after birth, prediction and recognition of RDS is so important. The precision and reliability of the stable microbuble test (SMR) and shake test as a predictor of respiratory distress syndrome were studied. A 11-=neonate who was born at Chungnam National University Hospital between November 1991 to September 1992 was selected randomely and studied. The results were as follows; 1) Among the 110 neonates, 13 cases were noticed as RDS. 2) Among the 13 infants with RDS, SMR results were zero and very weak in 11 cases, weak in 2 cases. Of the 97 infants with Non-RDS, 9 cases were weak, 88 cases were medium and strong, positive predictive value and negative predictive value was 100%, 98% respectively. 3) Of the 13 infants with RDS, Shake test result were negative in 8 cases, 1+ in 1 case, 2 + in 1 case and 4 + in 3 cases. Of the 97 infants with Non-RDS, 3 cases were negative, 9 cases were 1 +, 9 cases were 2 + and 63 cases were 4 +, positive predictive value and negative predictive value was 72.7%, 94.9% respectively. We conclude that the rapidity, simplicity and reliability of the stable microbubble test is more useful as a bedside procedure in identifying or predicting the infants who are likely to develop RDS than shake test.
