中文摘要 | 81例正常足月新生兒接受杜卜勒超音波心圖檢查,以測定動脈導管功能性關閉時間。檢查結果發現,6%的新生兒在出生後3~12小時第一次檢查時動導管已功能性關閉。其餘新生兒,14.8%在24小時以內關閉,71.6%在48小時內關閉,88.8%在72小時內關閉,96.3%在120小時內關閉,全部均在144小時以內關閉。剖腹生産者比經産道生産道生産者較慢關閉,但新生兒懷孕週數,性別及出生體重均與動脈導管功能性關閉的時間無關。 |
英文摘要 | Pulsed Doppler echocardiography was used to detect the functional closure time of the ductus arterious in 81 normal full-term Chinese newborns. The infants were examined 3-12 hours after birth initially and then twice daily until the ductus arteriosus could not be detected in two consecutive examinations. In 94% of the infants, a patent ductus arteriosus. was detected at initial study. In those infants, ductus arteriosus could not be detected in 14.8% by 24 hours of age, in 71.6% by 48. hours, in 88.8% by 72 hours, in 96.3% by 120 hours and in all by 144 hours of age. In newborns delivered by Cesarean section, the functional closure time of ductus arteriosus was significantly later than in newborns normally delivered. The ductus arteriosus closed in all newborns not delivered by Cesarean section at the age of 120 hours, but in only 90% of newborns delivered by Cesarean section the ductus closed at 120 hours of age. There were no significant differences in the functional closure of the ductus arteriosus in newborns of different sex, or gestational age. |
