Oxygen Saturation Trends in Newborn After Birth

Abstract

OBJECTIVE:To describe range of saturation in healthy newborn during first 10 minutes of life and their comparison on the basis of gestational age & mode of delivery. DESIGN, SETTING AND PARTICIPANTS: In this prospective observational study all healthy newborn (Term or Preterm) delivered normally or by caesarean section who did not require any intervention or support for survival. RESULT: A total of 300 newborns were analyzed. On average caeserian delivered newborn had lower SpO2 than infants born vaginally (p <0.001) and they took longer time to reach SpO2>85%. The median SpO2 did not reach 90% until 5 minutes of life in either group. Significant difference in oxygen saturation were also found at 1, 5 & 10 minute between pre-term & term newborn (P value <0.001). CONCLUSION AND RELEVANCE: Study data show that healthy newborns have relatively low oxygen saturation is first few minute of life. Oxygen should be administered to newborn only if it is indicated clinically.

Physiological vital sign ranges in newborns from 34 weeks gestation: A systematic review

“…[25][26][27][28][29] It has been reported that peripheral capillary oxygen saturations take up to 15 minutes to stabilise, 25 heart rate up to one hour 6 and, up to three days for functional closure of the four circulatory ducts. 1,3 However, there is paucity in data for the remaining transition period, which takes approximately 12-72 hours.…”

“…10,18 However, in some studies, for the newborns after normal delivery, SpO 2 level reached 90% by 5 minutes. [19][20][21] While some studies observed that the newborns delivered by caesarean section (CS) had lower SpO 2 levels during the initial 10 minutes and also took longer to reach 90%, 22,23 there were no significant differences in the SpO 2 values between the two modes of delivery after 5 minutes. 19 There has been wide variation in the SpO 2 levels and trends during the initial minutes of life in healthy neonates after normal vaginal delivery (NVD) and CS, leading to confusion and ambiguity regarding the optimal reference ranges.…”

Quantifying physiological vital sign differences in newborns from 34+0/7&nbsp;weeks of gestation and establishment of vital sign reference ranges for the late preterm population

“…Newborn vital signs during the immediate stabilisation period (up to two hours following birth) have been explored in a number of studies. [82][83][84][85][86] It has been reported that peripheral oxygen saturation levels take up to 15 minutes to stabilise, 82 heart rate up to one hour 64 and functional closure of the four circulatory ducts up to three days. 16,62 However, there is a paucity of data for the remaining transition period, which takes approximately 12 -72 hours.…”
