2. DEFINITION:
•A labour is called
precipitate when the
combined duration of the
first and second stage is
less than two hours.
3. INCIDENCE
• It is common in multipara and may be
repetitive.
• Rapid expulsion is due to the combined effect
of hyperactive uterine contractions associated
with diminished soft tissue resistance.
• Labour is short as the rate of cervical
dilatation is 5cm per hour or more for the
nulliparous women.
4. MATERNAL RISKS;
It includes
• Extensive laceration of the cervix, vagina and
pernium (to the extent of complete perineal tear)
• PPH due to uterine hypotonia that develops
subsequent to unusual vigorous contractions
• Inversion
• Infection
• Uterine rupture
• Aminiotic fluid embolism
5. FETAL RISKS:
It include
• Intracranial stress and haemorrhage because
of rapid expulsion without time for moulding
of the head.
• The baby may sustain serious injuries if
delivery occurs in standing position ,bleeding
from the torn cord and direct hit on the skull
are real hazards.
6. TREATEMENT:
• The patient having previous history of precipitate
labour should be hospitalised prior to labour.
• During labour, the uterine contraction may be
suppressed by administering ether or magnesium
sulphate during contractions.
• Delivery of the head should be controlled.
• Episiotomy should be done liberally .
• Elective induction of labour by low rupture of
membranes and conduction of controlled delivery is
helpful .
• Oxytocin augmentation should be avoided.
Nulliparous” is a fancy medical word used to describe a woman who hasn't given birth to a child. she's never been pregnant — someone who's had a miscarriage, stillbirth, or elective abortion but has never given birth to a live baby
