Слайд 2Cesarean section is obstetrical operation with the help of which
fetus and afterbirth are extracted from uterus throw incision of
uterus and laparotomy incision.
Слайд 3Historical Background
In the first, according to legend, Julius Caesar was
born in this manner, with the result that the procedure
became known as the Caesarean operation. Several circumstances weaken this explanation.
Слайд 4Continuation
The second explanation is that the name of the operation
is derived from a Roman law, supposedly created in the
8th century BC by Numa Pompilius, ordering that the procedure be performed upon women dying in the last few weeks of pregnancy in the hope of saving the child. This lex regia—king's rule or law—later became the lex caesarea under the emperors, and the operation itself became known as the caesarean operation. The German term Kaiserschnitt—Kaiser cut—reflects this derivation.
Слайд 5Continuation
The third explanation is that the word caesarean was derived
from the Latin verb caedere, to cut. This explanation seems
most logical, but exactly when it was first applied to the operation is uncertain. Because section is derived from the Latin verb seco, which also means cut, the term caesarean section seems tautological—thus cesarean delivery is used. In the United States, the ae in the first syllable of caesarean is replaced with the letter e. In the United Kingdom, Australia, and most commonwealth nations, the ae is retained.
Слайд 7The recommended percentage of
caesarean sections (WHO, 2008) – 10-15%.
Слайд 8WHO: every year the world produces about 18.5 million cesarean
section.
A study of perinatal outcomes showed that except for caesarean
section are at least 3.18 million Caesarean sections were necessary, but not made.
Analyzing data on indications for delivery by the WHO experts have concluded that in some cases the indications for CS were not. In sum, for the year was performed approximately 6.20 million "extra" Caesarean section.
Слайд 9 Maternal death associated with caesarean section (about 40
per 100,000 births) is 4 times higher than that for
all types of vaginal delivery (10 per 100,000 births) and 8 times higher than for normal vaginal delivery (5 to 100,000).
Слайд 10 Caesarean section increases the risk of serious complications
in the next pregnancy:
- ectopic pregnancy,
- placenta previa,
- preeclampsia,
- birth of a child with a small for gestational period mass,
- anomalies of placenta,
- placental abruption,
- uterine rupture.
Слайд 11Selected Complications Associated with Emergency Cesarean Delivery (According to Decision-to-Incision
Interval from the Maternal-Fetal Medicine Units Network):
Maternal Outcome:
Endometritis,
Wound complication, Operative injury;
Neonatal Outcome:
5-minute Apgar score less than 3, Umbilical artery pH <7.0, Hypoxic ischemic encephalopathy, Fetal death in labor, Neonatal death with or with no malformations.
Слайд 12Methods (types) of Cesarean section:
Intraperitoneal Cesarean section:
corporeal cesarean section
low cesarean
section (with the help of transverse incision in the inferior
uterine segment).
Low cesarean section with temporary isolation of abdominal cavity.
Extraperitoneal cesarean section.
Cesarean section by Starc’s method.
Method of operation is determined by the obstetrical state, condition of woman, condition of fetus, doctor’s level of proficiency.
Слайд 13Today, one of the most frequent indications for elective caesarean
section is the presence of a uterine scar from a
previous caesarean section.
According to the literature, repeated cesarean section involves a significant risk of maternal complications and increases the risk of placenta previa and increment the next pregnancy.
Слайд 14Indications for Cesarean Section during pregnancy (planned and urgent) are:

Слайд 31Postoperative care for woman in early postoperative period:
Recovery Suite
Postoperatively, the
amount of bleeding from the vagina must be monitored closely,
and the uterine fundus must be identified frequently by palpation to ensure that the uterus is remaining firmly contracted.
Once the mother is fully awake, bleeding is minimal, blood pressure is satisfactory, and urine flow is at least 50 mL/hour, she may be transferred to her room.
Слайд 32Continuation
After transfer to her room, the woman is assessed at
least hourly for 4 hours and thereafter, at intervals of
4 hours.
Blood pressure, pulse, temperature, uterine tone, urine output, and amount of bleeding are evaluated.
The incision is inspected each day. By the third postpartum day, showering is not harmful to the incision.
Слайд 33Postoperative care for woman in early postoperative period:
Uterine state checkup.
Checkup
of blood discharged from vagina.
Checkup of hemodynamics.
Adequate anesthetization.
Unless there
are complications during the puerperium, the mother generally is discharged on the third or fourth postpartum day
