As regards Rh immunization, about 30% of Rh negative mothers get exposed to their babies Rh positive blood during birth and 70% do not. Mothers blood and fetal blood are separated in the placenta, with fetal blood remaining inside. By what mechanism, do 70% of mothers remain unexposed but 30% of mothers are exposed to fetal blood during birth? Can Rh immunization be avoided by careful non-violent delivery of the placenta using gravity and abdominal muscles in squatting position? https://www.researchgate.net/publication/363216491_Novel_Third_Stage_Protocol_wwwyoutubecomwatchvAAJPW4p6rzUReduces_Postpartum_Hemorrhage_at_Vaginal_Birth
Episiotomy creates a gash where fetal blood could enter. Do women with no perineal damage experience lower rates of Rh immunization?
Clamping the cord as soon as possible is important, when the placenta separates from the uterus, mothers blood can enter the baby's circulation more easily(from high to low pressure). Do not, - roughly - suck out mother''s blood/mucus from the baby's nose throat in which often some mother's blood is present that can enter the baby if its mucosa is damaged. If a patient is or could be HIV positive (or Hep B, or Zika, or Covid etc.) the same applies of course: mothers blood is dangerous for the baby. Google "Family planning as part of reproductive health, including the hiv/aids aspects" readable on line. Chapter 14 discusses this.
