TERMINOLOGIES Umbilical cord presentation:
Presence of cord in front of presenting part before the rupture of membranes.
Umbilical cord prolapse: Descent of umbilical cord following rupture of the membranes, through the cervix so that it lies either along side the fetal part or in front of presenting part into the cervix/ and into or out of vagina.

TERMINOLOGIES Occult prolapse – Cord lies adjacent to
the presenting part, but not beyond the presenting part in the presence of intact or without intact membranes.
Overt prolapse – cord which is visible or palpable with naked eyes following rupture of membranes.

implications
![Page 9: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/9.jpg)

![Page 10: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/10.jpg)
ETIOLOGY OR RISK FACTORS - 1 Non engagement of fetal head: 1.Unengaged or poorly applied presenting part 2. High parity - weak muscles 3. Unstable lie – weak muscles 4. Malpresentations 5. Breech presentations
![Page 11: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/11.jpg)
ETIOLOGY OR RISK FACTORS -2 Related to Uterine and Pelvic
factors: 1. Polyhydramnios 2. Long umbilical cord 3. Low lying placenta 4. Contracted Pelvis
![Page 12: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/12.jpg)
ETIOLOGY OR RISK FACTORS -3 Related to Fetal factors: 1. Prematurity 2. Low Birth Weight 3. Second twin 4. Congenital malformations
![Page 13: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/13.jpg)
ETIOLOGY OR RISK FACTORS -4 Related to clinical procedures: 1. ARM in high presenting part 2. External cephalic version 3. Stabilizing induction of labor 4. Manual rotation of fetal head in OP position 5. Application of fetal scalp electrode 6. Internal podalic version of second twin
![Page 14: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/14.jpg)
ETIOLOGY OR RISK FACTORS -5 Other causes 1. PROM 2. Male fetuses 3. Anomalies of uterus
![Page 15: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/15.jpg)
COMPLICATIONS: Neonatal morbidity and Mortality –
as high as 50 % due to 1. Hypoxia - is due to cord compression by the presenting part and also due to vasospasm of umbilical vessels 2. Operative trauma 3. Delay in transport 4. Congenital malformations 5. Prematurity Maternal morbidity :
![Page 16: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/16.jpg)
DIAGNOSIS Overt cord can be seen in the vagina or
outside the vagina- feel pulsations Variable deceleration and bradycardia
on CTG following rupture of membranes. Fetal bradycardia – following fundal
pressure Meconium stained liquor
![Page 17: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/17.jpg)
PREVENTION Ultrasound examination for
malpresentation and cord presentation. Avoid ARM in unengaged head Routinely doing PVE following
spontaneous rupture of membranes. Controlled ARM in poly hydramnios –
Stabilizing induction. Bradycardia and variable decelerations
- do either vaginal examination or speculum examination
![Page 18: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/18.jpg)
MANAGEMENT Depends upon viability of the fetus and
absence of fetal malformations. Quick action should be taken to
expedite the delivery. Survival of fetus depends on swift action Prepare for Emergency interventions like Cesarean section and or Instrumental delivery. Multidisciplinary approach or Team work
is required
![Page 19: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/19.jpg)
MANAGEMENT Discontinue IV oxytocin infusion
Oxygen by mask – 15 lits/ mt
CORD – C – call for help - O – organize for delivery - R – Relieve pressure - D – Delivery Funic repositioning: with soaked warm saline reposition into vagina
![Page 20: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/20.jpg)
ELEVATING THE PRESENTING PART Avoid presenting part pressure over cord
by digital or manual pressure. Instruct the patient to not to exert
pressure or pushing. Bladder filling with 500 700 ml of
saline. Tocolysis? Inj.Terbutaline 250 microgams
SCly Positioning of the patient:1. Knee chest position2. Trendelenburg position3. Exaggerated Sims or lateral position
![Page 21: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/21.jpg)

TRENDELENBURG POSITION
![Page 23: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/23.jpg)
EXAGGERATED SIM’S POSITION
![Page 24: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/24.jpg)
DO’S AND DON’TS Do’s – Replace the cord into the vagina to
prevent from vasospasm with saline soaked pad
Continuous monitoring of FHR Inform the patient Minimal handling of cord Don'ts – Replace inside the uterus Excessive handling of the cord.
![Page 25: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/25.jpg)
COMMUNITY LEVEL Knee chest face down position Bladder filling with saline In Ambulance – left lateral position Manual elevation – if a nurse or family
physician there Urgent transfer to center with cesarean
facilities and neonatal care.
![Page 26: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/26.jpg)
Stage I of Labor Prepare for Emergency Cesarean section Inform the senior pediatrician Delivery should be done within 30 minutes If fetal death occurs, try for vaginal delivery. Stage II Labor: Expedite delivery with liberal episiotomy
and instrumental delivery. If there is fetal heart disturbance and not in
favor of vaginal delivery plan for Emergency Cesarean section.
![Page 27: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/27.jpg)
Extreme prematurity with cord prolapse:
1. Below or around 24 weeks – counsel the patient.
If she wishes to continue pregnancy if FHR is normal and patient willing for up to 3 weeks
If patient does not agree allow for vaginal delivery with or without oxytocin infusion
![Page 28: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/28.jpg)
FETAL MORTALITY Overall – 50 % First stage of labor – 75 % Second stage – 50 % Neonatal death – 4 % Perinatal mortality – 20 % Asphyxia – Hypoxic ischaemic
encaephlopathy - Cerebral palsy
![Page 29: Umbilical cord prolapse - Dr.Suresh Babu Chaduvula](https://reader033.fdocuments.us/reader033/viewer/2022061616/5556eb7bd8b42a0f028b5046/html5/thumbnails/29.jpg)
PROGNOSIS Good with vertex presentation than
Breech. Good in Primigravida than in multi.
