Premature Rupture of Membranes (PROM)
Definition Spontaneous rupture of the membranes any time beyond 28 th week of pregnancy but before the onset of labour is called premature (pre labour) rupture of membranes.
q TERM PROM When the rupture occurs beyond 37 th week but before the onset of labour it is called term PROM q PRE TERM PROM When the rupture occurs before the 37 th completed weeks it is called preterm PROM q PROLONGED RUPTURE OF MEMBRANE Rupture of membrane for 24 hours before delivery is called prolonged rupture of membrane
INCIDENCE 10 % of all pregnancies
Causes Increased friability of the membranes Decreased tensile strength of the membranes Polyhydramnios Cervical incompetence Multiple pregnancy Infection – Chorio-amnionitis, UTI, lower genital tract infections
Diagnosis q Subjective symptom is Escape of watery discharge per vagina either as a gush or slow leak. q Usually confused with 1. Hydrorrhoea gravidarum 2. Incontinence of urine
Confirmation of Diagnosis 1. Speculum examination 2. Examination of the collected fluid from posterior fornix for Ø Detection of p. H ( 6 – 6. 2) Ø Ferning pattern 3. 0. 1% Nile blue sulphate test – orange blue colouration of cells 4. USG
Investigations Complete blood count Urine analysis and culture High vaginal swab for culture Vaginal pool to estimate phosphatidyl glycerol USG NST
Dangers q Preterm labour and prematurity q Ascending infection q Cord prolapse q Dry labour q Fetal pulmonary hypoplasia q R. D. S
Management - Assess gestational age and fetal weight - Patient not in labour - Absence of infection and fetal distress - biophysical profile and NST To monitor maternal pulse, temperature, FHS and start prophylactic antibiotics Pregnancy < 34 weeks > 37 weeks Pregnancy > 34 weeks Pregnancy Expectant management Wait for spontaneous onset Wait for spontaneousto continue for fetal maturity. of labour for 24 – 48 hours labour for 24 hours Transfer patient with “fetus in FAILS Utero” to equipped centre Induction of labour Induction of
