ABSTRACT
PPROM can be classified into PPROM < 24 weeks (usually 16-23 6/7 weeks, and called also previable or midtrimester or very early PPROM-see also end of this chapter) and PPROM at 24 0/7 to 36 6/7 weeks. PPROM at 24 to 36 weeks can be further subdivided into PPROM at 24 to 33 6/7 weeks (early PPROM) and PPROM at 34 to 36 6/7 weeks (near-term PPROM-for management, see also chap. 19).
