uterine inversion & cord prolapse
TRANSCRIPT
UTERINE INVERSIONUTERINE INVERSION
Definition:Definition:
Descent of uterine fundus into the cavity, through cervix or even vulva
Rare event (1 in 10000 pregnancies)
Descent of uterine fundus into the cavity, through cervix or even vulva
Rare event (1 in 10000 pregnancies)
Risk factors:Risk factors:
Mismanagement of 3rd stage of labor: uterus not contract, violent cough
Strong traction on umbilical cord with excessive fundal pressure
Abnormal adherent of the placenta
Uterine anomalies
Fundal implantation on the placenta
Short cord
Previous uterine inversion

Sign & Symptoms:Sign & Symptoms:
Haemorrhage (94%)
Severe abdominal pain in 3rd stage
Hypotension with bradycardia: shock out of proportion to the blood loss (neurogenic due to increased vagal tone)
Uterine fundus not palpable abdominally
Mass in the vagina on vaginal examination.

Management of uterine inversionManagement of uterine inversionUterine Inversion
Remove placentaOxytocic infusion (40
units/500mls NS)Antibiotics observe O’Sullivan hydrostatic method
-dependent part replace into vagina-5L or more physiological solution
deposited onto posterior fornix-assistant create water tight seal
Manual reduction-apply pressure to
dependent part of uterus-simultaneous pressing
with other hand on other part which inverted last
GA/ stabilize patient
UTERUS REPLACED
Immediate replacement
Resuscitate, IV access, fluids/ bolus replacement

CORD PROLAPSECORD PROLAPSE
Definition:Definition:
Cord prolapse has been defined as the descent of the umbilical cord through the cervix alongside (occult) or past the presenting part (overt) in the presence of ruptured membranes.
Cord presentation is the presence of the umbilical cord between the fetal presenting part and the cervix, with or without membrane rupture.
Cord prolapse has been defined as the descent of the umbilical cord through the cervix alongside (occult) or past the presenting part (overt) in the presence of ruptured membranes.

Background:Background:
Cases of cord prolapse appear consistently in perinatal mortality enquiries, and one large study found a perinatal mortality rate of 91/1000.1
Prematurity and congenital malformations account for the majority of adverse outcomes associated with cord prolapse in hospital settings but birth asphyxia is also associated with cord prolapse.
Perinatal death has been described with normally formed term babies, particularly with planned home birth. Delay in transfer to hospital appears to be an important contributing factor.
Asphyxia may also result in hypoxic–ischaemic encephalopathy and cerebral palsy.
The principal causes of asphyxia in this context are thought to be cord compression and umbilical arterial vasospasm preventing venous and arterial blood flow to and from the fetus.
There is a paucity of long-term follow-up data of babies born alive after cord prolapse in both hospital and community settings.

Diagnosis:Diagnosis:
Cord presentation and prolapse may occur without outward physical signs and with a normal fetal heart rate pattern.
The cord should be examined for at every vaginal examination in labour and after spontaneous rupture of membranes if risk factors are present or if cardiotocographic abnormalities commence soon thereafter.
With spontaneous rupture of membranes in the presence of a normal fetal heart rate patterns and the absence of risk factors for cord prolapse, routine vaginal examination is not indicated if the liquor is clear.
Cord prolapse should be suspected where there is an abnormal fetal heart rate pattern (bradycardia, variable decelerations etc), particularly if such changes commence soon after membrane rupture, spontaneously or with amniotomy.

Prevention:Prevention:
Anticipate cord prolapse in those with risk
Stabilizing induction if polyhydramnios or high presentation part.
No ARM if presenting part is unengaged or mobile or in cord presentation
Early admission for breech presentation, abnormal lie, and polyhydramnios
Bradycardia or variable fetal heart rate deceleration -> prompt VE or speculum examination
