PPROM AND TERM PROM Flashcards
Full meaning of PROM
- Prelabour rupture of membranes
- Premature rupture of membranes
Another term for PROM
Prelabour amniorrhexis
T/F: Premature rupture of membranes is rupture of membranes before the onset of labor, irrespective of gestational age
T
3 types of PROM
- Preterm PROM = before 37wks
- Term PROM = 37 or more wks
- Previable PROM = Before 28 wks
What is latency period in PROM
Period from ROM to onset of contractions/labour
T/F: If a woman has ROM and goes into labour within 1 to 2 hours, it is not PROM
T
Minimum latency period of PROM
1 - 2 hours
Median latency after PPROM
7 days
What is prolonged ROM
Any ROM that persists for more than 24 hours and prior to the onset of labor
Incidence of PROM in all pregnancies
12%
Incidence of PROM in term pregnancies
8%
Incidence of PROM in preterm deliveries
30%
3 pathways to preterm birth
- Spontaneous preterm labor (40%)
- Premature rupture of membranes (35%)
- Medical intervention (25%)
T/F: Multifetal pregnancies comprise 3% percent of all live births
T
% of preterm births resulting from spontaneous preterm labour
40% (40 - 50%)
% of preterm births resulting from premature rupture of membranes
35% (25 - 40%)
% of preterm births resulting from medical intervention
25% (20 - 35%)
