Hello, I would be happy to help you with your question.
First of all, use of
steroids for maturation of fetal lungs is only indicated in the setting of a threatened
premature birth before 34 weeks. You have not said anything that would indicate that this is the case. If there is no imminent threat of a premature birth (preterm contractions,
cervical dilation, cervical shortening, fetal growth restriction, etc.) then the steroids would not be indicated in her case. With regard to this recommendation, I would definitely
seek a second opinion. Perhaps there are additional details that you have not mentioned.
In terms of your question, yes steroids will increase her blood sugars for a short period of time, and yes they will be difficult to keep within those targets that you mentioned. I am going to defer the last questions regarding targets for blood sugars and the physiology of
insulin as I think that these should be addressed after you get a second opinion.
