The statistical observation of the time of passage of the first stool and first void was performed on 800 cases of newborns, were carried at the newborn nursery and premature baby room, National Seoul Hospital, during the past two years from Jan, 1977 to Dec, 1978. The population study was performed on sex, gestational age, Apgar score, mode of delivery, and maternal disease or premedication during the pregnancy, congenital anomalies of the newborn infants. The results were as following. 1) The cases of passage of the first stool within 1 hour and 24 hours after birth were 15%, 96.9% of total boy and 12.4%, 97.1% of total girl in each cases. There were no remarkable differences in the time of first stool between the boys and girls. The cases of the first stool passage who was delayed until 48 hours of age were more frequent in boys(0.7%) than girls. The cases of the first voiding in the delivery room or within 1 hour after birth showed 8.2% of boys and 6.7% of girls and the cases after 24 hours of age showed 6.5%, 5.2%, relatively. This revealed that boys were more earlier than girls in their first voiding. 2) According to gestational age, a total of 98.5% and 94.5% of the fullterm infants had their first stool passing and voiding within 24 hours after birth. But 10.8% of preterm infants had their first stool just after birth and 2.4% of preterm infants had their first meconium after 48 hours of age. So this group tended to pass their first stool later than other groups of infants. And also 23.2% of postterm infants had their first stool just after birth and this group tended to pass their first meconium earlier than other group of infants. A total of 97.6% of preterm infants voided in the delivery room and 88.4% of postterm infants had urinated within 24 hours after birth. This showed that preterm infants tended to void early and the postterm infants tended to void later than other groups of infants. 3) According to apgar score, 41.7% of newborn infants with low Apgar score(score 0~4) had their first stool passage in the delivery room and 66.7% of low Apgar score group infants voided within 24 hours after birth and this group tended to pass their stool earlier and void later than high Apgar score group infants. 4) The delivery method did not influence to the general population in the time of first urination and stool passage. 5) The infants of preeclampsia or diabetic mother tended to void early and the infants born to mother who received diuretics during the pregnancy voided early also. The newborn infants who had combined with congenital anomalies of gastrointestinal tract or genitourinary tract were delayed the time of passage of the first stool or first urine. |
