Any consent form should include the probabilities of risk for uterine rupture, hysterectomy, transfusion, iatrogenic pathology, etc. The options for delivery should be presented on an equal basis. A signature line would appear in each column to indicate the choice. The mother should be allowed to take the form home and discuss it, in order to make an informed decision, rather than being pressured to sign it on the spot. Flamm nor Phalen address the subject of diagnosis.
Vigilance is the key.
There should always be someone monitoring the FHT, although improved monitoring equipment can reduce the need for additional staff. The papers by Jones, Farmer, Leung, Scott, contain information about diagnosing uterine rupture, the most reliable symptom being prolonged bradycardia. Improvements to monitoring equipment can reduce the cost of additional staff for monitoring the fetal heart rate. Variable and late decelerations are nothing more than phase differences between the fetal heart rate and uterine contraction sinusoids, and while not trivial, are still easy to detect electronically.
