Umbilical cord prolapse by dr alka mukherjee dr apurva mukherjee nagpur m.s. ...alka mukherjee
The umbilical cord is a flexible, tube-like structure that, during pregnancy, connects the fetus to the mother. The umbilical cord is the baby's lifeline to the mother. It transports nutrients to the baby and also carries away the baby's waste products. It is made up of three blood vessels – two arteries and one vein.
Umbilical cord prolapse is a complication that occurs prior to or during delivery of the baby. In a prolapse, the umbilical cord drops (prolapses) through the open cervix into the vagina ahead of the baby. The cord can then become trapped against the baby's body during delivery. Umbilical cord prolapse occurs in approximately one in every 300 births.
An umbilical cord prolapse presents a great danger to the fetus. During the delivery, the fetus can put stress on the cord. This can result in a loss of oxygen to the fetus, and may even result in a stillbirth.
The most common cause of an umbilical cord prolapse is a premature rupture of the membranes that contain the amniotic fluid. Other causes include:
• Premature delivery of the baby
• Delivering more than one baby per pregnancy (twins, triplets, etc.)
• Excessive amniotic fluid
• Breech delivery (the baby comes through the birth canal feet first)
• An umbilical cord that is longer than usual
Diagnosis of a prolapsed umbilical cord can be in several ways.
During delivery, the doctor will use a fetal heart monitor to measure the baby's heart rate. If the umbilical cord has prolapsed, the baby may have bradycardia (a heart rate of less than 120 beats per minute).
The doctor can also conduct a pelvic examination and may see the prolapsed cord, or palpate (feel) the cord with his or her fingers.

Vet obst lecture 10 Cesarean in domestic farm and pet animals
1. Cesarean section in domestic farm and pet
animals
Prof G N PUROHIT
Head, Department of Veterinary Gynecology and Obstetrics,
College of Veterinary and Animal Science, Rajasthan University
of Veterinary and Animal Sciences, Bikaner, Rajasthan, India
2. Cesarean section (Hysterotomy, Celiotomy)
• One of the oldest surgical procedures The term appears to be
derived from the Greek term caeso matris utera meaning
cutting the mothers uterus.
3. Risk factors
Heifers age less than 2 years
Prolonged gestation
Higher age of cows
Peidmont Sire
Previous cesarean section
4. Maternal indications
• Immature heifers
• Pelvic fractures, deformities
• Cervical dilation failure
• Uncorrectable uterine torsion
• Uterine tears
• Double muscling in beef breeds such as Charolais, Limousin,
Belgian Blue
5. Fetal indications
• Absolute fetal oversize
• High value calf such as embryo transfer
• Uncorrectable fetal maldispositions
• Fetal defects such as fetal dropsical conditions, monsters,
conjoined twins.
• Recovery of gnotobiotic calves
6. Restraint Depends on operative site
• Standing in a chute -- flank laparotomy
• Ventral recumbency—Midline
• Right or left dorsal recumbency—Paramedian, lower flank,
oblique ventro-lateral
7. Anesthesia
• General anesthesia or heavy sedation with xylazine (0.03 to 0.1
mg/kg IV) is indicated for exceptional cases
• Paravertebral nerve block (Last thoracic and 1st 3 spinal nerves)
• Provides good anesthesia and relaxation but induces marked
hyperemia in muscle layers and greater degree of hemorrhage
• Inverted L block
• Epidural anesthesia
11. Pre-operative considerations
• Fasting not possible in emergency operations but possible in
elective cesarean sections.
• Animals restrained in recumbency may develop ruminal
tympany and regurgitate ruminal fluid during the operation.
• Sufficient fluid replacement and antibiotics or other
appropriate therapy should be given to stabilize the condition
of the patient
12. Operative sites
• Flank laparotomy- Left and right Incision in the middle of
paralumbar fossa 3-5 cm ventral to transverse process of
lumbar vertebrae
• Lower flank laparotomy 10-15 cm ventral to transverse
process
• Midline (linea alba)
• Paramedian Between linea alba and subcutaneous abdominal
vein extending just behind the umbilicus to the udder. Care
should be taken to avoid incising caudal deep epigastric artery
18. The proper positioning of the cow and incision
site for the ventrolateral celiotomy
Standing left paralumbar celiotomy.
The placement of the incision is indicated
by the dashed line.
The locations for the midline (top line), right paramedian
(middle line) and right low oblique or paramammary
approaches (bottom line)
19. • Oblique ventrolateral-Above the arcus cruralis in front of stifle
and extending cranioventrally in a oblique direction.
• Paramammary approach
• Disadvantages of recumbent approaches include increased
surgical time, increased risk of intra-operative hemorrhage,
post-operative seroma formation and in incisional herniations.
20. Surgical Technique
• Shaving and scrubbing with soap and water followed by scrubbing
with savlon. Then disinfect with Chlorhexidine, povidone or
isopropyl alchohol.
• Apply a shroud on the operative site and fix it with clamps
• Skin incision using a scalpel followed by separation of
subcutaneous tissue by blunt dissection.
• Incision of muscles ligating major vessels
• Incise the peritoneum (Glistening white)
• The omental fat and rumen are deflected to one side
21. • The uterus is held by an extremity and brought to the incision site
and packed with sterile drapes.
• Incise the uterus over the greater curvature avoiding cotyledons
and blood vessels.
• The calf is removed and the umbilical cord is clamped and cut. The
placenta should be removed if possible. The uterus is washed with
normal saline.
• Surgeons must change the gloves and suture the uterus using 2 or
3 chromic catgut and continuous inverting 1 or 2 layers of sutures
such as Utrecht, Lembert or Cushing suture.
22. • The uterus is washed with saline, the blood clots are removed and
uterus is replaced back in to the abdominal cavity.
• The surgeon should change gloves after replacement of uterus.
• The peritoneum and transversus muscle are closed by chromic
catgut using simple continuous sutures.
• The internal and external oblique abdominal muscles are sutured.
To avoid dead space the suture layers should be periodically tacked
down to the preceding layer of suture
• The skin is sutured using simple interrupted or ford interlocking
sutures utilizing silk and a sterile gauze must be tied over the skin
suture to minimize external contamination.
23. Cesarean section: cattle and buffalo via oblique ventro-lateral approach The animal placed in dorsal recumbency, skin incision,
subcutaneous dissection, the peritoneum is exposed, the uterus is exposed and taken out
25. Post-Operative Care
• Cleaning of operative site with spirit for 3-5 days
• Fluid therapy for 3-5 days in poor condition cows
• Cows with an emphysematous fetus must be given imidazole
derivatives.
• Antibiotics for 3-5 days
• Anti-inflammatory drugs for 2-3 days
• Cows operated with ventral surgical
approaches require stall rest for 6 weeks
27. Cesarean section in sheep and goat
Similar to cattle except that only 0.5-1.0% lidocaine should be
used by dilution of 2% solution as accidental infusion leads to
convulsions
28. Cesarean section in the sow
Approaches include ventral flank and sub-lumbar
Anaesthesia: Halothane (Landrace breed is susceptible so do not use
in this breed) + nitrous oxide and oxygen after IV administration of
thiopentone (150-200 mg/Kg IV)
Premedication
Diazepam (0.5-1.0 mg/Kg IM)
IV anesthetics
IM azaperone (2mg/Kg) and IV metomidate (2mg/Kg) with local
infiltration
Ketamine (15-20 mg/Kg IV + diazepam (0.5-1.0 mg/Kg)
Xylazine 2.2 mg/Kg IM however, IV anaesthetics are known to cause
hind limb paralysis.
29. Cesarean section in the mare
Serious and dangerous in the absence of facility
Foal suffers anoxia within 1-2 h of second stage of labor due to
dehiscence of allantochorion
Indications
Transverse presentation
When other measure have failed
Vulvo-vaginal trauma
Pelvic fracture
30. Anesthesia
Methohexitone sodium 5 mg/Kg or thiopentone (10 mg/Kg)
followed by inhalation anesthesia using halothane and oxygen
Currently
xylazine 0.25 – 0.5 mg/Kg IV or 0.5-1.0 mg/Kg are used as
preanaesthetic followed by guaifenesin 5-10%, ketamine 1.5-
2.0 mg/Kg IV and inhalation anaesthesia using isoflurane or
servoflurane gas anaesthesia at many places. 15-20 ml of
bupivacaine at the site locally
31. Sites Midline (Preferred), Flank and Ventral
Marcenac incision is a lower abdominal incision that extends from a
point posterior to last rib to a point in front of the fold of the flank
and uses local infiltration anesthesia instead of general anesthesia.
The uterine incision leads to profuse bleeding and hence double rows
of sutures should be used. Postoperative abdominal pain and
subcutaneous edema may be seen. Oxytocin can also induce colic.
Oxytetracycline should be avoided as it precipitates salmonellosis. If
laminitis develops uterine lavage should be considered and
antiallergics should be given.
32.
33. Cesarean section in the bitch
• Cesarean section should be performed before the dystocia
affected bitch fatigues or distress occurs in the pups.
• Prompt intervention is necessary for minimizing fetal death.
• Bitches that have been in prolonged labor, those with a uterus
containing dead or decaying fetuses or a friable uterus, or
those showing signs of endotoxemia or septicemia should
have caesarean sections. The toxic bitch requires supportive
fluid and antibiotic therapy prior to, during and following
surgery.
34. General Aesthetic Protocols
ProtocoI 1
1. Premedicate with atropine (0.04 mg/kg IM)
2. Induce with diazepam (0.2 mg/kg IV) and thiopental
(8-12 mg/kg IV); intubate

glycopyrrolate (0.011 mg/kg IM)
2. Induce with oxymorphone (0.1 mg/kg IV) and
intubate gently; if bitch resists intubation, add
thiopental (4-8 mg/kg IV)
3. Maintain with methoxyflurane (1% early; decrease to
less than 0.3% if possible and add 50% nitrous oxide)
36. Protocol 5

Droperidol-fentanyl (1 mg/20-30 kg IV)
Diazepam (0.2-0.5 mg/kg IV) with ketamine HCI (4-8 mg/ kg IV)
Acepromazine (0.1 mg/kg IM or IV, not to exceed 4 mg) with
oxymorphone (0.11 mg/kg IV)
4. Intubate; maintain with isoflurane, halothane, enflurane

37. • Regional Aesthetic Protocol
• 1. Premedicate with atropine (0.04 mg/kg IM)
• 2. Administer bupivacaine (1 ml/3.5 kg) epidurally
• 3. Administer oxymorphone (0.1 mg/kg IV)
38. • Anesthetic protocols have also utilized administration of
atropine (0.04 mg/kg BW, S.C) immediately followed with
xylazine+ketamine (1 mg/kg BW+10 mg/kg BW, I.M) along
with diazepam (0.5 mg/kg BW, I.V). However, xylazine is
considered to be fetotoxic.
39. Cesarean section in the camel
Done in sitting position
Flank and ventrolateral approaches are used. Care
should be taken in flank approach when incising the
peritoneum to avoid accidental cut on the spleen.
Xylazine and local infiltration anaesthesia is used.
The dose of xylazine suggested for camels is 0.25 mg/Kg IV
Post-operative skin healing is delayed and hernias and
seroma formation is common
