Labor Flashcards
Indication of induction of labor
> Maternal
- Postdate
- PE, Eclampsia, PIH
- GDM
- Prolonged PROM
- Indeterminate APH
> Fetus
- Multiple pregnancy
- Oligohydramnios
- Reduced fetal movement
- IUD
- Chorioamnionitis
Contraindication for induction of labor
> Maternal
- Previous C-section
- Previous myomectomy
- Placenta praevia
- Obstruction of birth canal
- Active genital herpes
- Invasive cervical cancer
> Fetus
- Malpresentation: face/ brow
- Abnormal lie: transverse/ oblique
- Unstable lie at term
- Breech presentation
- Severe fetal compromised - IUGR
- Cord prolapse
Prostin protocol in SGH
> Day 1
- Maximum 2 prostin per day, 6 hours apart
- If cervix remain unfavorable, rest for the night and come tomorrow
> Day 2
- Insert 3rd prostin in the morning
- If still unfavorable, discuss with specialist
> Day 3
- 4th prostin (if specialist decide)
Contraindication for Prostin
- Allergy to prostaglandin
- Prior C-section or other prior major uterine surgery (eg: myomectomy)
- Asthma (PG cause bronchoconstriction)
- Preexisting regular painful uterine activity - relative CI
Pros and Cons of Mechanical induction of labour
> Pros
- Effective, safe, cheaper and associated with low incidence of uterine hyper stimulation
> Cons
- Bleeding
- Device expulsion
- Cervical laceration
Contraindication for amniotomy
- Maternal Hep B, HSV
- High presenting part (cord prolapse if not engaged)
Complication of IOL
> Amniotomy
- Cord prolapse
- Injury to fetal part
- Amniotic fluid embolism
> Prostin/ Oxytocin
- Uterine hyperstimulation
- Uterine rupture
> Others
- Fetal distress
- Chorioamnionitis
- Failed induction -> EMLSCS
Management of uterine hyperstimulation
> CTG normal
- Reduce the oxytocin infusion rate
- Place in left lateral position
- Continuous CTG monitoring
- Close monitoring of contraction
> CTG non-reassuring
- Stop oxytocin infusion
- Consider tocolytic (eg: IV salbutamol 100ug or subQ terbutaline 250ug)
Induction vs Augmentation of labor
> Induction
- Not in labor
- Labor not start spontaneously
- To initiate the onset of labor
> Augmentation
- In labor
- Labor start spontaneously
- To speed up the process of labor
Type of breech presentation
- Extended (frank): Most common
- Flexed (complete)
- Footling: least common
Contraindication for ECV
> Maternal
- Placenta previa
- Recent APH
- PROM
- Multiple pregnancy
- Preeclampsia
- Uterine scar
> Fetus
- Oligohydramnios
- Polyhydramnios
- Unstable lie
- Abnormal CTG
Step for ECV
- Patient lie supine with 30” tilt either to left or right
- Apply talcum powder/ gel over abdomen
- With pelvic grip, breech is displaced to one iliac fossa
- The other hand is placed over fetal head
- Both hand works together to turn the fetus in FORWARD SUMMERSAULLT
- Gentle, intermittent version force is applied over both pole
- Max 3 attempts
- Done at/ after 37 weeks
- Failed -> repeat 1 week later/ ELSCS at 39 weeks
Possible presenting diameter of fetal skull
- 9.5cm: suboccipito-bregmatic (vertex, flexed)
- 9.5cm: submento-bregmatic (face)
- 11.0cm: oxxipito-frontal (vertex, military)
- 13.5cm: vertico-mental (brow)
Contraindication of VBAC
- Previous uterine rupture
- Previous classical C-section
- > = 2 previous C-section scar
- Prior inverted T or J incision
- Interval <18 months
Sign of impending uterine rupture
- Abnormal CTG
- Maternal pulse >100 bpm
- Maternal BP <100/60
- Persistent suprapubic pain
- Hematuria
- Increase PV bleeding
- Loss of station of the presenting part
