3. Caesarean
section
A Caesarean section is a method of delivery
by operation, in which a fetus is taken from
the uterus by cutting through the walls
of the abdomen and uterus.
The word caesarean is said to derive either
from an edict by Julius Caesar that woman
was about to die in advanced child birth and
this operation was performed to save the
child and mother.
from the Latin word caeso matris utera
means cutting of mother's uterus.
4. The
caesarean
operation
It has high maternal and fetal survival rates and often
it is less exhausting, faster and safer than fetotomy.
There are three main goals:
(1) Survival of the dam
(2) Survival of the kid
(3) Maintenance of fertility
5. A successful
prognosis
depends on
several
factors
Skill and speed of the surgeon
Duration of dystocia
Physical condition of the dam
Availability of skilled assistance
Surgical environment
Concurrent disease
Presence of a live kid.
6. Indications
The reasons for surgery include most causes of dystocia, but analysis
of published cases shows that the following six major indications
account cumulatively for 90% of all caesarean operations:
1. Fetomaternal disproportion
2. Incomplete dilatation of the cervix
3. Irreducible uterine torsion
4. Fetal monsters
5. Faulty fetal disposition (presentation, position or posture)
6. Fetal emphysema
9. Surgical
Technique
The surgical technique is performed in following steps
1. Opening of the flank
2. Locating the uterus
3. Opening of the uterus
4. Removal of the fetus
5. Management of the placenta
6. Closing of the uterine incision
7. Closing of the laparotomy incision
10. Opening of the flank
The incision needs to be around
20cm in length, running
vertically down from
approximately 10-12cm below
the transverse process.
Right flank (para-lumbar)
incision with the animal in
left lateral recumbency. Check
bleeding at every step
Before opening the peritoneum,
the hemostats are used to control
bleeding points in the muscle
layers which should be removed
after ligating the vessels.
11. Locating
the Uterus
The uterus lies caudal to
and below the rumen.
If uterus is not visible, then
it is searched by pushing
the rumen forward.
12. Opening of
the Uterus
The opening should be made over the
fetal extremity in the greater curvature
of the pregnant uterine horn.
The incision should be approximately
15 cm.
long in the direction of the longitudinal
muscles and in between the
cotyledons, otherwise profuse
hemorrhage may occur.
13. Removal of the Fetus
• If the fetus in anterior
presentation, then removed rear
end of fetus first at caesarean
section and if the fetus is in
posterior presentation, then
remove front end.
14. Management of
Placenta
• If the placenta is easily
and quickly
detachable, it should
be carefully removed
from the uterus.
• If not, it should be left
in the site even when
the cervix is closed.
15. Closing of the Uterine incision
• Uterine incision is cleaned with saline.
•The uterus should be sutured with a
continuous inverting pattern
(standardly a Cushing pattern is used).
• Using a non-synthetic absorbable
suture material (i.e. Catgut No.1 or O)
16. Closing of the
laparotomy incision
Before the closure of the
incision, a quantity of
crystalline penicillin or
ampicillin (1-2 gm) may be
instilled into the abdomen as a
soluble solution to minimize
the risk of peritoneal infection.
18. Complications
of caesarean
• Peritonitis
• Wound breakdown
• Seroma formation - A pocket of sterile
serous fluid accumulates between muscle
layers or under the skin.This can be
confirmed when a sterile needle is inserted
- serum flow-out.
• Retention of the fetal membranes
• Metritis
• Infertility
• Mastitis (E. coli infection)
• Sudden death.
