Fetal viability typically occurs at about 24 to 25 weeks of gestation. [2] When the fetus is in between the ages of 24–34 weeks, a glucocorticoid is given to the patient about 24 hours before the procedure to stimulate lung maturity. An ultrasound is performed before the procedure to view the position of the fetus and may be used during the ...
Medical viability is generally considered to be between 23 and 24 weeks gestational age, meaning that these newborns have a < 50% chance of either dying or surviving with severe impairment if active care is instituted; this applies to most fetuses at ≥ 24 weeks of gestation, and to some fetuses at 23 weeks of gestation with favourable risk ...
This rate is inconsistent across countries. In the United Kingdom 7.9% of babies are born pre-term and in the United States 12.3% of all births are before 37 weeks gestation. [19] [20] Approximately 0.5% of births are extremely early periviable births (20–25 weeks of gestation), and these account for most of the deaths. [21]

Although hysterotomy is crucial for resuscitation of the mother in such situations, if the gestational age is less than approximately 24 to 25 weeks the procedure will necessarily lead to the death of the fetus (or fetuses), as this is estimated to be the lower limit for fetal viability. [4]
About 6 weeks of age: The first parvo vaccine. This may not do much good if the mother has been vaccinated and the puppy still has maternal immunity from the mother's milk.
For example, if there is a gestational age based on the beginning of the last menstrual period of 9.0 weeks, and a first-trimester obstetric ultrasonography gives an estimated gestational age of 10.0 weeks (with a 2 SD variability of ±8% of the estimate, thereby giving a variability of ±0.8 weeks), the difference of 1.0 weeks between the ...
They were born four weeks ago, making them newborn cubs. There's a reason why the two lion cubs had to wait a month before seeing the vet. As the video from the zoo explains, the cubs' mama ...
