CAESAREAN SECTION
Definition delivery of a fetus by incision
through the abdominal wall and uterus
Types of Caesarean Section
LSCS (Lower segment Caesarean section)
Upper segment / Classical Caesarean section
Transverse incision over the lower segment of the uterusRelatively avascularDoes not take an active part in contraction and retraction during labourAccess to the presenting part of the fetusEncourages good healing
Vertical incision over the fundus and body of the uterusMore vascularTakes an active part in contraction and retraction during laborDoes not give access to the presenting partPoor healing
Emergency Lower Segment Caesarean Section
Indications : Fetal distress CPD Umbilical cord prolapse Placenta abruptio Placenta praevia Failed instrumental delivery Failed IOL
Elective Lower Segment Caesarean Section
Indications : 2 / > previous Caesarean sections A previous classical Caesarean section CPD Placenta praevia Breech presentation Multiple pregnancy IUGR Tumours
Upper Segment Caesarean Section
1. avoided unless.. 2. Indications :
Inaccessible lower segment(fibroids) Impacted transverse lie Major placenta praevia Ca of cervix (prior to performing radical
hysterectomy) Post-mortem Caesarean section
Procedure
1. Anesthesia2. Abdominal incision3. Uterine incision4. Amniotic sac incision5. Delivery of baby6. Umbilical cord clamped7. Delivery of placenta8. Stiching of uterus
Anesthesia1. Elective
-regional anesthetics (spinal/epidural)-numbs only the lower portion of the body
2. Emergency - Spinal/GA -effect faster
1. Anaesthesia
2. Abdominal Incision
1. Elective Horizontal/transverse/
Pfannenstiel incision across the abdomen, just above the pubic area.
2. Emergency prefer a vertical cut,
from below the navel to just above the pubic area.
Transverse (Pfannenstiel)
Vertical
More popularLimited exposure
Hernia less common
Less popularRapid entry and good exposureHernia more common
3. Uterine incision The sheath, then
muscles of the uterus are separated, producing a hole for the delivery of the baby.
The incision can be either vertical incision or horizontal incision.
4. Amniotic sac incision
Cutting through the amniotic sac
The amniotic fluid is allowed to escape
5. Delivery of baby
Delivery of baby With one hand, the
surgeon reaches into the uterus and lifts the baby's head.
An assistant pushes down on the mother's upper uterus to help guide the baby out
6. Umbilical cord clamped and cut
7. Delivery of placenta
Delivery of placenta controlled cord traction
8. Stitching uterus is stitched closed (with
dissolvable stitches), inspect the ovaries and tubes, then close the different tissue layers
and put staples or stitches into the skin.
Stitch 3 layers for upper segment (thicker) and 2 layers for lower segment.
ComplicationsMATERNAL1. Infection. (genital tract, UTI, wound)2. Bleeding.3. Injury to bladder and bowel. 4. Anesthesia complication. 5. Thromboembolism.Next delivery 1. Uterine rupture 2. Placenta previa 3. Placenta accreta
Complications
BABY1. Premature birth. 2. Breathing problems. 3. Low Apgar scores. 4. Fetal injury.
Advantages
MATERNAL-Reduced uterovaginal prolapse-Reduced urinary incontinence
