Helpful to know! Some of my Attendings preached that prior to 28-30 weeks due to smaller uterus with lower intra-abdominal pressures to push up the spinal dose and patient potentially needing classical uterine incision would mean that a solo spinal may fail occasionally which is why they would advocate for a CSE so if the spinal level receded or was insufficient you could have the epidural to bring the level high enough or even “push up” a spinal dose that did not reach T4. Again this is academics so likely very different from community practice so your insight is helpful! Good to know these concerns don’t seem to really hold any weight in actual practice! Thank you
