Points well taken. More recent studies are beginning to question the
concept of latency gained by antibiotic use, combined with the increasing
data regarding neurologic injury sustained during expectant management of
PPROM - which have resulted in moving the threshold of delivery in the
picture of PPROM from 36 weeks to 34 weeks and two papers this spring
suggesting that maybe that number should be 32 weeks. However, this
decision is being made by balancing the risks of pulmonary immaturity
compared to the risk of neurologic sequelae. In Rich's case, you have an
absolute surgical case and evidence that the fetal lungs are not mature,
which makes a relatively straight forward pediatric surgical case much more
complex. As such, this decision has to be made by including three issues;
pulmonary maturity, neuologic sequelae and surgical risk.
With regard to the CRP issue, I disagree. If you have a lab that can
provide a CRP value in a timely manner, it can give you a lead on other
clinical assessments of developing infection. I can't use it where I am at
because the turn-around time for the test is too long, however, I have used
it in other places with good results. As with anything, I don't use it as
my sole determinant, but rather as an additional piece of the puzzle to aid
in decision making.

If increased latency does not improve outcome, it does not have any benefit
of itself - this was shown in the amoxiclav arm of ORACLE, where there was
increased latency but worse outcome if anything with antibiotic. CRP is
almost valueless.
