Contradiction of spinal anesthesia in pregnant females

I strongly encourage you to pick up additional resources to answer this question for you, however.. according to Johns Hopkins Manual of OBGYN they list: uncorrected/untreated coagulopathy, skin infection at the site (side note: i've heard of anesthesia providers not doing thing through tattoos), bacteremia, refractory HoTN/hypovolemia, increased ICP, extensive surgery at the site.
Disclaimer: not a CRNA

unstable CNS dz, elevated ICP, aortic stenosis, to name more...
