2. Introduction
• Caesarean Section is a delivery of a viable
fetus through an incision in abdominal wall and
intact uterus.
• Most common operation performed worldwide.
• Primary Caesarean is the first CS to be done on
a patient, while Secondary Caesarean is the
repeat procedure.
3. Indications for Caesarean Section
• Previous C.S
• Dystocia or dysfunctional labour:
• Cephalopelvic disproportion
• Tumours complicating pregnancy
• Fetal macrosomia
• Malpresentations
• Deep transverse arrest
• Abnormal uterine action
• Failed forceps or vacuum
• Failed induction
• Fetal distress and cord prolapse
4. • Breech presentation (complicated breech and
footling presentation
• Other fetal indication
• Severe intrauterine growth restriction
• Multiple pregnancy
• Antepartum hemorrhage:
• Placenta praevia
• Abruptio placenta
• Vasa praevia
• Maternal problems:
• Elderly nullipara
• Prolonged period of infertility or pregnancy following
in vitro fertilization
• Bad obstetric history
• Severe preeclampsia and diabetes
5. • Caesarean Section on request.
Most Common Indications (85% of the cases)
• Previous CS (most common)
• Dystocia
• Fetal distress
• Breech Presentation
6. Lower Segment Caesarean Section
(LSCS)
• A lower (uterine) segment Caesarean section
(LSCS) is the most commonly used type of
Caesarean section used today.
• It includes a transverse cut just above the edge
of the bladder and results in less blood loss and
is easier to repair than other types of Caesarean
sections.
• The advantage is that the healing of the lower
segment is better as it is quiescent and high
tensile strength.
7. Preparing the patient for LSCS
• Cross matched blood
• Introduction of indwelling catheter
• Skin prepared by antiseptic solution and draped
• Prophylactic antibiotics to prevent puerperal
sepsis.
• Left lateral tilt to reduce aortocaval compression
and risk of supine hypotension.
• Thromboprophylaxis for high risk patients.
• Anesthesia, Regional is always better(spinal or
epidural)
• In emergency CS, prevention of Mendelson’s
8. Abdominal Incisions
• Pfannensteil Incision
▫ Most commonly used
▫ Transverse curvilinear incision just above the
pubic hairline.
• Joel Cohen Incision
▫ A modified transverse incision placed about 3 cm
below the line joining the anterior superior iliac
spines.
▫ Higher than the Pfannensteil incision & not
curved.
• Maylard Incision
▫ Where more exposure needed in a transverse
9.
10. Procedure
• Uterine Incision
∙ Correct any dextrorotation
∙ Visualize the lower segment (Doyens retractor)
∙ Loose peritoneum is divided transversely and
separated from the bladder by blunt incision
∙ Small incision made in the lower segment and
extended laterally using scissors.

14. • Delivery of the Baby
• Hand slipped into the uterine cavity and head is
gently levered out.
• Fundal Pressure maybe exerted on fetal buttocks
• Mouth and nose are suctioned to prevent
aspiration and the rest of the body is delivered by
gentle traction.
• The umbilical cord is doubly clamped.
• LSCS Complete Video
15. • If the presentation is breech,
▫ The feet are hooked out.
▫ The rest of the baby delivered as in case of a
vaginal breech delivery.
▫ Breech delivery via LSCS
• Deeply Impacted head,
▫ The head may deeply impacted in midpelvis with
a thinned out lower segment.
▫ Patwardhan method can be used in deeply
impacted head.
16. • Transverse or Oblique lie,
▫ Corrected to a longitudinal lie before the uterine
incision is made.
• If transverse lie with ruptured membranes and
an undeveloped lower segment,
▫ Extension of the uterine incision may be needed
• In case of dorsoinferior position with rupture
membranes,
▫ More difficulty and this is one situation where a
transverse incision considered
17. • Closure of uterine incision
▫ Oxytocin infusion is started.
▫ Placenta and membranes are removed by controlled
cord traction.
▫ The uterine edges are held with Allis forceps or
green-Armytage forceps.
▫ The uterine incision is closed in two layers of
continuous suture
▫ It is important that the two angles and any other
bleeding points be securely ligated.
▫ Haemostasis is ensured.
▫ The tubes and ovaries are inspected.
18.
19. • Closure of the Abdomen
▫ Closed in layers after confirming mop and
instrument count.
▫ The parietal peritoneum need not be closed.
▫ The rectus sheath is carefully approximated with
delayed absorbable sutures to minimize the
chance of wound dehiscence.
▫ The skin approximated with mattress sutures, a
subcuticular suture or clips.
20. Post Operative Care
• First 6-8hrs, monitor the vitals and look for
vaginal bleeding and condition of the uterus.
• First Day, paraenteral fluids are given, blood
transfusion if needed, antibiotics,
thromboprophylaxis, breast feeding after 4hrs &
oral fluid started after 6hrs.
• Second day, catheter and dressing removed and
early ambulation.
• Third day, light solid diet can be started & laxative
*if.
21. Other Types of Caesarean Sections
• Inductions: constricting ring, lower segment not
formed & prematurity
• Incision can extend downward (cervix , vagina,
bladder) & increased chance of rupture in next
pregnancy if incision extend to upper segment
Lower Segment Vertical
Incision
• Indications: Unapproachable lower segment,
cervix ca, ant placenta previa with previous CS,
some cases of transverse lie with ruptured
membrane & conjoined twins
• Healing is difficult, scar rupture is more in next
pregnancy
Classical Caesarean

• Method of dealing with severe infectionExtraperitoneal

• Done as a life saving measures for severe atonic
PPH & ruptured uterus, adherent placenta,
multiple large myomas, severe sepsis and Ca in

arrest to save a live fetus

24. Questions?
Q. All the following are indications for a
Caesarean section except
a) Abruptio placenta
b) Footling breech
c) Placenta Percreta
d) Untreated Stage 1 Carcinoma cervix
e) Active Genital herpes
25. Vaginal Birth After C-Section
(VBAC)
• Once A C-section is not always a C-section
• If the Patient had a cesarean delivery before,
she may be able to deliver your next baby
vaginally. This is called vaginal birth after
cesarean, or VBAC
26. Risks Involved
• Scar rupture
▫ More chance of rupture with a classical section
scar
• Adherent placenta
▫ Risk of morbid adherence of placenta increases
with each CS.
▫ Risk of severe PPH and caesarean hysterectomy
is increased
• Operative interference
• Peripartum hysterectomy
27. Management
• Elective Caesarean Section
• Trial of Labour after Caesarean (TOLAC)
▫ Ultrasound is of importance
▫ Myometrial thickness is 3.5mm or more there is
Low risk of uterine rupture.
▫ To assess placental location
28. Contraindications to VBAC
• Previous classical incision
• Previous two LSCS
• Previous inverted T incision
• Previous low vertical incision
• Malpresentations
• Cephalopelvic disproportion
• Multiple Pregnancy
• Patient’s refuse to undergo trial of labour
29. Selection of Cases
