Early onset sepsis can occur in the first week of life. It usually is apparent on the first day after birth. This type of infection is usually acquired before the birth of the infant. Premature rupture of membranes and other obstetrical complications can add to the risk of early-onset sepsis. If the amniotic membrane has been ruptured greater ...
Early-onset neonatal sepsis is found to be 0.77 to 1 per 100,000 live births in the U.S. In premature babies, the incidence and mortality rates are higher due to the weakness of their immune system. For infants with low birth weight, cases of early-onset sepsis is found to be about 26 per 1,000 and 8 per 1,000 live births.
A temperature rise above 38 °C (100.4 °F) maintained over 24 hours or recurring during the period from the end of the first to the end of the 10th day after childbirth or abortion. (ICD-10) Oral temperature of 38 °C (100.4 °F) or more on any two of the first ten days postpartum.
GBS-EOD manifests from 0 to 7 living days in the newborn, with most of the cases of EOD being apparent within 24 h from birth. GBS-LOD starts between 7 and 90 days after birth. [4] [12] [14] [22] Roughly 50% of newborns of GBS-colonized mothers are also GBS-colonized and (without prevention measures) 1-2% of these newborns will develop GBS-EOD.
Apgar scoring is performed one minute and five minutes after birth. Scoring ranges from 0 to 10, with 0 indicating severe neonatal distress and 10 indicating a smooth transition to extrauterine life. [1] Newborns transitioning into extrauterine life will undergo periods of reactivity. These periods are divided into three stages.
When PROM occurs at term (after 36 weeks), it is typically followed soon thereafter by the start of labor and delivery. About half of women will give birth within 5 hours, and 95% will give birth within 28 hours without any intervention. [11] The younger the baby, the longer the latency period (time between membrane rupture and start of labor).
As the fetal hypothalamus matures, the activation of the hypothalamic–pituitary–adrenal (HPA) axis initiates labor through two hormonal mechanisms. The end pathway of both mechanisms lead to contractions in the myometrium, a mechanical cause of placental separation, which is due to the sheer force and contractile and involutive changes that occur within the uterus, distorting the placentome.
About two to five days after the birth the breasts begin to produce milk. This sometimes is described as "the milk coming in". [4] Information can be provided to the mother before the birth to enhance the understanding of breastfeeding and the support that will be available to make it successful. [5]
