Cervix dilatation 4cm
Effacement 100%
Engagement 1/5
Diagnosis: Preterm labor
6. Case study cnt
Spontaneous rupture of membrane at 13h15’
14h45’
Eutocic delivery of preterm baby
APGAR 3, weight:900gr
Transferred in neonatology (but died in the evening)
8. Term pregnancy - 37 to 42 weeks gestation
Preterm pregnancy 24 to 37 weeks gestation
Preterm labor is occurrence of uterine contractions
between 24 to 37 weeks of gestation( amenorrhea)
Preterm labor is the presence of contractions of
sufficient strength and frequency to effect progressive
effacement and dilation of the cervix between 20 and
37 weeks' gestation (WHO)
Gynecology and obstetrics clinical protocols & treatment guidelines
21. Goals of Treatment of PTL
Halt contractions temporary by tocolysing
Allow 48 hr+ for steroids to be given
Allow for transport to delivery location with
NICU capability
22. Steroids
Reduce incidence of RDS, IVH, NEC, sepsis, and
mortality by about 50%
Dexamethasone 6 mg IM 12 hr x 4 (cervix dilatation <
4cm)
Dexamethasone 12mg IM 12 hr x 2 ( cervix dilatation >
4 cm) (Gynecology and obstetrics clinical protocols &
treatment guidelines)
24. Tocolysis
Risk/benefit ratio of various treatments
Beta agonists (salbutamol, terbutaline)
Tachycardia, hypotension, tremor, palpitations, chest
discomfort, hypokalemia, hyperglycemia
Magnesium sulfate
Nausea, flushing, fatigue, diaphoresis, loss of DTRs, respiratory
depression, cardiac arrest
Indomethacin
Maternal GI SE, premature closure of ductus, oligohydramnios
Atosiban
Possible increase in fetal/neonatal morbidity/mortality; not available
in US
CAUTION we should avoid combining tocolytics (Green-top
guideline no:1b feb 2011)
25. Tocolysis
Nifedipine
Low cost
Oral
Low incidence of side effects
(hypotension, dizziness, flushing)
Often considered first line
Dose:
20mg start dose and 10-20 mg 3 to 4 times daily
Total ≥ 60mg appears to be associated with increase of 3 to 4
fold the bad event of headache and hypotension
Caution: be careful when use in multiple pregnancy, rupture
of membrane, sepsis, diabet mellitus and cardiac disease.

gynecology C-obs 15)
26. Management after Tocolysis
If maternal and fetal conditions are stable, can be
managed at home
Avoid excessive physical activity; most advocate pelvic
rest
Continued tocolytics have not shown definite benefit
27. Prevention of PTB
Reduce/eliminate risk factors, if possible
Not proven to be effective: bedrest, home uterine
monitoring, prophylactic tocolytics, prophylactic
antibiotics, abstinence
28. To retain
Preterm labor is the presence of sufficient uterine
contractions to effect progressive cervix changes between
20 and 37 weeks' of gestation
Various strategies that have been used to prevent or treat
preterm labor, haven't proven effective.
Tocolysis should be considered only for 2 days-
for corticosteroids action,
gain time for transfer to a tertiary center .
