Study Notes
Obstructed Labour
- A condition where the baby can't be delivered despite good uterine contractions and a fully dilated cervix due to an obstruction in the passage.
- Common causes include transverse lie and conjoint twins.
- Mothers often appear exhausted and dehydrated.
- P/A examination reveals tachypnea and acidotic breathing.
- A Bandl's ring, which is a groove between the upper and lower uterine segments, is visible on a diagram.
Complications
- Uterine rupture
- Vesicovaginal fistula (VVF):
- Occurs 7-10 days after labour due to ischemic injury of the bladder.
- Characterized by constant dribbling of urine.
- The most common cause of VVF in developing countries.
Management
- Immediate C-section followed by maternal resuscitation.
- Avoid waiting, oxytocin, and instrumental delivery.
Active Phase
- Dilatation of Cervix:
- Primigravida: 1.2 cm/hr
- Multigravida: 1.5 cm/hr
- Descent of Fetal Head:
- Primigravida: 1 cm/hr
- Multigravida: 2 cm/hr
Protracted Active Phase
- Criteria: Cervical dilatation less than 1 cm/hr.
Second Stage of Labour
- Main Event: Delivery of the baby.
- Epidural anesthesia can prolong this stage by 1 hour.
- Average Duration:
- Primigravida: 3 hours (without epidural) or 4 hours (with epidural)
- Multigravida: 2 hours (without epidural) or 3 hours (with epidural)
- Arrest of Descent: No descent of the fetal head for 2 hours in primigravida or 1 hour in multigravida.
Management of Prolonged Second Stage
- Scenario 1: Fetal distress in the second stage with a fully dilated cervix (10 cm).
- Station above +2: C-section.
- Station at +2 or below: Forceps.
- Scenario 2: Bandl's ring with prolonged second stage.
- C-section is performed. No instrumental delivery.
- Scenario 3: Cephalopelvic disproportion (CPD) present with prolonged second stage, moulding, and caput.
- Station above +2: C-section.
- Station at +2 or below: Forceps or vacuum.
- Scenario 4: Prolonged second stage with normal fetal heart rate and no CPD or obstructed labour.
- Station above +2: C-section.
- Station at +2 or below: Forceps or vacuum.
Requisites for Instrumental Delivery
- Full cervical dilatation.
- Station ≥ +2.
- Forceps are preferred over vacuum in cases of fetal distress.
Fetal Position
- Relationship of the denominator to the maternal pelvis.
- Most Common Positions:
- Antenatal: LOT > LOA.
- During labour: LOT.
- Active labour: DOA.
- Most common occipitoanterior position: LOA.
- Most common occipitoposterior position: ROP.
- Normal vaginal delivery: Positions 1 to 5.
- Occipito-posterior delivery: Positions 6 to 8.
- Breech: Denominator: Sacrum. Position: Left Sacro-anterior.
Face Presentation
- Denominator: Mentum.
- Position: Left Mento-anterior (during labour).
Identifying Fetal Position
- Identify the occiput: Near the posterior fontanelle.
- Based on the position of the occiput:
- Near the pubic symphysis (PS): Occipito-anterior.
- Near the sacral promontory (SP): Occipito-posterior.
- Midway between PS & SP: Occipito-transverse.
- If the occiput is directed to the examiner's right: mother's left, and vice versa.
Bandl's Ring
- AKA: Retraction Ring
- Cause: Obstructed labour
- Site: Between upper and lower uterine segments
- Stage of labour: Second
- Palpable: P/A
- Visible: Not visible
- Maternal & fetal condition: Maternal & fetal distress
- Relieved by: C-section
Schroeder's Ring
- AKA: Construction Ring
- Cause: Spasm of a segment of uterus due to inadvertent use of oxytocin
- Site: First or second stage
- Palpable: P/V
- Visible: Not visible
- Maternal & fetal condition: Normal
- How to relieve: Cessation of oxytocin, uterine relaxants (Terbutaline), if no relaxation: C-section.
WHO Recommendations
At time of admission:
-
Recommended:
- Note vital signs.
- Perform Leopold manoeuvres.
- Auscultate for fetal heart sounds.
- P/V examination (C/1 in active bleeding).
-
Not Recommended: Routine enema, routine pelvic examination, routine CTG, routine pelvic shaving.
In the first stage of labour:
- Ambulation: Allowed in early labor.
- Oral Intake:
- Solids: Not allowed.
- Liquids: Allowed (Stop 2 hours before surgery).
- Lies in lateral position: Allowed in late labour/membranes ruptured (Stop 6 hours before surgery).
- Bladder function: Encouraged to relieve every hour.
Leopold's Manoeuvres
- Purpose: To determine the position and presentation of a fetus during pregnancy.
Steps Before the Manoeuvre
- Introduce yourself to the mother and explain the procedure.
- Empty the mother's bladder
- Position the mother supine with knees slightly flexed.
- Ensure the mother is adequately exposed.
- Warm your hands.
- Position yourself on the right side of the patient.
Procedure
- First Leopold: Palpating the fundal height, looking for fetal parts.
- If felt: Longitudinal lie.
- If not felt: Transverse lie.
- Soft, broad, irregular & not independently ballotable (movable): Buttocks.
- Rounded, firm, globular, ballotable: Head.
- Second Leopold: Examine the umbilical/lateral area for the fetal part.
- Smooth, continuous, rigid area: Back.
- Multiple, irregular, Knob-like structures: Limbs.
Interpretation
- **Lie of the fetus:** Longitudinal or transverse.
- **Presentation:** Cephalic or breech (buttocks or head first).
- **Position:** Determined by which side of the fetus is on the maternal left or right.
Stages of Labour
First Stage of Labour
- Latent Phase:
- Ends at dilatation of:
- ACOG: 5 cm
- New WHO: 4 cm
- Old WHO: 3 cm
- Ends at dilatation of:
- Active Phase:
- Begins at dilatation of:
- ACOG: 6 cm
- New WHO: 5 cm
- Old WHO: 4 cm
- Begins at dilatation of:
| Event | Primigravida | Multigravida |
|---|---|---|
| Duration in hours | 12 hours | 8 hours |

Prolonged Latent Phase
- Latent phase lasting ≥20 hours in primigravida or ≥14 hours in multigravida
- Causes: Unripe cervix, occipito-posterior position, false labour pains.
- Management: Prostaglandins (PGE1 & PGE2), wait for spontaneous delivery, therapeutic rest.
Partogram
- A graphic record of the progress of labor.
- The modified WHO partogram (based on old WHO recommendations) begins at 4 cm dilatation.
