24h - 70%
48h - 85%
96h - 95%
What are the immediate risks of TERM PROM?
Cord prolapse
Cord compression
Placental abruption
What are the criteria for expectant management for TERM PROM?S
Fixed cephalic presentation GBS negative No evidence of infection Normal CTG No VE, cervical change Commitment to 4 hourly matenral temp, evaluation of vaginal loss and assessment of fetal wellbeing
What is the method of choice for active management of TERM PROM?
Oxytocin
PGs may have a role in women with an unfavourable cervix
What are the delayed risks of TERM PROM?
Maternal infection
Neonatal infection: death, chronic lung disease, cerebral palsy
Role of the initial assessment of women with TERM PROM?
Confirm
- diagnosis (sterile speculum, no VE, can use amnisure)
- gestation
- presentation
Assess maternal and fetal wellbeing
Cause of false positive rates for amnisure?
blood or semen, alkaline antiseptics, certain lubricants, trichomonas, bacterial vaginosis
False positive rate for amnisure?
19-30%
Cause of false negative rates for amnisure?
prolonged membrane rupture and minimal residual fluid
When should amnisure be used?
When there is uncertainty re diagnosis. It shouldn’t be part of routine assessment.
Summary meta analysis of PROM management:
Outcomes?
- Maternal chorioamnionitis
- definite or probable early-onset neonatal sepsis
- caesarean section rate
- Neonate receiving antibiotics
- Neonatal admission to a neonatal special care
or intensive care unit
