HISTORY
Bindusara (born c. 320 BC, ruled 298 c.272BC), the second Mauryan Samrat (emperor) ofIndia, is said to be the first child born bysurgery
The name comes from traditional belief that
Julius Caesar was delivered by this operation(???)
Mothers usually died; the first recorded womansurviving a Caesarean section was in the1580s, in Siegershausen, Switzerland
European travelers in the Great Lakes region
of Africa during the 19th century observedCaesarean sections being performed on aregular basis
The first modern Caesarean section wasperformed by German gynecologist FerdinandAdolf Kehrer in 1881.

PROCEDURE
Both general and regional anaesthesia (spinal, epidural orcombined spinal and epidural anaesthesia) are acceptable
Regional anaesthesia is preferred: it allows the mother to beawake and interact immediately with her baby, other advantagesinclude the absence of typical risks of general
anesthesia: pulmonary aspiration of gastric contentsand intubation
General anesthesia: heavy, uncontrolled bleeding and veryurgent cases, when there is no time to perform a regionalanesthesia

RECOVERY
After delivery: recovery room (for about three hours- woman isclosely monitored)
If everything is well, woman is moved to postpartum room with IV andurinary catheter still in place
women are encouraged to be out of bed within six hours after
surgery and usually can begin eating within 24 hours if they arepassing gas
Three to five days after delivery patient is dissmised- there should beno strenuous work for up to six months

RISKS
Mother Higher mortality rate than in
vaginal birth
Abdominal surgery risks(postoperative adhesions, incisional
hernias, wound infections)
Anaesthesia risk
Severe blood loss
Postdural-puncture spinalheadaches
More likely to haveproblems with laterpregnancies (????)
Child Transient tachypnea of the
newborn ( wet lung)
Potential for early deliveryand complications
Injuries with scalpel andfractures
Higher infant mortality risk
the risk of death in the first 28days of life: 1.77 per 1,000
live births among women whohad C-sections/ 0.62 per1,000 for women whodelivered vaginally

SAMPLEAND METHODS
2069 women booked for elective caesarean section at
term with a singleton pregnancy excluded placenta praevia, thrombocytopenia, coagulopathies,
previous major obstetric haemorrhage (>1000 mL), or knownfibroids; women receiving anticoagulant treatment; those who didnot understand English; and those who were younger than 18years
Double blind, placebo controlled, randomised trial Intervention group: intravenous slow 5 IU oxytocin bolus over
1 minute and additional 40 IU oxytocin infusion in 500 mL of0.9% saline solution over 4 hours (bolus and infusion)
Placebo group: 5 IU oxytocin bolus over 1 minute and 500 mLof 0.9% saline solution over 4 hours (placebo infusion) (bolus
only).
conducted from February 2008 to June 2010 in fivematernity hospitals in the Republic of Ireland

RESULTS
no difference in the occurrence of major obstetrichaemorrhage between the groups
the need for an additional uterotonic agent in thebolus and infusion group was lower than that in thebolus only group
women were less likely to have a major obstetrichaemorrhage in the bolus and infusion group thanin the bolus only group if the obstetrician was junior
rather than senior

CONCLUSION
The addition of an oxytocin infusion after caesareandelivery reduces the need for additional uterotonicagents but does not affect the overall occurrence ofmajor obstetric haemorrhage.
