Returning to the conversation around safety in homebirth...
This is a real question/concern not just presented by parents -but other medical providers. Which is, er, interesting. Because the knowledge of anatomy & physiology explains why (when done properly) waterbirth cannot cause drowning.
Let me explain👇🏼
When your baby is born there is a nerve on their face (the TRIGEMINAL nerve) that is activated by the cool air, which causes them to take their first breath.Their lungs, already filled with fluid, then expand which causes negative pressure in the chest, which draws in air & pushes out the fluid in the lungs into surrounding tissues. This first breath also begins the physiological cascade in their circulatory system -triggering the fetal shunts to close & redirect blood flow fully through the lungs. But what does this even mean?
When your baby is born *under* the warm water, the trigeminal nerve has not been activated. It is when they're brought up out of the water that it is activated & they take their first breath.
💦 It's important that the provider you hire has experience with providing waterbirth because there are important things they should know to keep babies safe. Most midwives are the experts in waterbirth BUT not all.
Here are some guidelines:
✅️ Mothers should keep their bottom fully submerged when delivering the head. To prevent that activation of the trigeminal nerve. Otherwise she needs to stand up completely to birth her baby.
✅️ Whoever is pulling the baby out of the water should do so with care, to prevent snapping the umbilical cord which would cause the baby to lose blood. Ideally, the mother does because she can feel the pull on the cord. Some umbilical cords are really short or need to be unwrapped from baby.
✅️ The water temperature of the birth pool needs to be maintained between 97-99⁰. Not too hot & not too cold.
✅️ 💩 Ninjas (your birth team) should remove any f***l matter as soon as possible.
✅️ Hydration & monitoring your temp should be performed frequently to assess for over heating & dehydration.
✅️ If an emergency occurs during the birth, the mother should be supported in getting out of the tub immediately.
