目的比较不同时间行新生儿脐带残端二次剪脐的临床效果,探讨新生儿脐带残端二次剪脐的最佳时机。方法随机筛选无脐疝的正常新生儿1600例,首次采用气门芯在距脐轮1mm处结扎,远端1cm处剪断脐带,随机分成4组,每组400例,各组脐带残端二次剪脐时间分别在出生后的24h、36h、48h、60h。观察比较4组新生儿脐部渗血、分泌物、创面干燥愈合时间、返院处理情况。结果36h、48h、60h组脐部渗血发生率显著低于24h组,差异有统计学意义(P<0.0001);24h、36h、48h组第4天脐部分泌物渗出率显著低于60h组,差异有统计学意义(P<0.0001);24h、36h、48h组出院后因脐部创面未愈合返院处理例数低于60h组,差异有统计学意义(P<0.0001);24h、36h、48h组创面干燥愈合时间比60h组缩短,差异有统计学意义(P<0.0001)。结论新生儿二次剪脐最佳时段为36～48h,该时段进行二次剪脐后,脐部渗血发生率低、分泌物少、创面干燥及愈合时间短,因脐部创面未愈合返院率低。
Objective To explore the best time of second cutting neonates＇ umbilical cord stump by comparing the effects of recuttings made at different times. Methods 1 600 normal neonates without umbilical hernia were randomly sampled, and were divided into four groups. The first-time cutting for all the groups was made at the valve core with the near end 1 mm and far end 1 cm from the navel chakra, and the second, at the 24th , 36th, 48th and 60th hours, respectively, after the birth. Then observations were made of the umbilical blood oozing, secretion, the time at which the wound surface dried and healed, and the hospital revisiting for further treatment. Results The rates of umbilical blood oozing among the 36th-hour, 48th-hour and 60th-hour groups were distinctly lower than that among the 24th-hour group, the differences being statistically significant （P〈0.0001）; the rates of umbilical secretion oozing on the 4th day among the 24th-hour, 36th-hour and 48th-hour groups were statistically significantly lower than that of the 60th-hour group （P〈0.0001）; the time that the wound surface dried and healed among the 24th-hour, 36th-hour and 48th-hour groups was shorter than that for the 60th-hour group, the differences having statistical significance （P〈0.0001）; the numbers of cases those revisited the hospital owing to the non-healing of the wound surface among the 24th-hour, 36th-hour and 48th-hour groups were smaller than that of the 60th-hour group （P〈0.0001）, the differences having statistical significance. Conclusion The best time of second cutting of neonates＇ umbilical cord stump is at 36th to 48th hours after the birth. Second cutting made at this time involves lower possibility of umbilical blood oozing, less umbilical secretion, shorter time for the healing of the wound surface and fewer hospital revisiting due to non-healing of the umbilical wound surface.
