What is a Caesarian Section

cesarean delivery
Caesarian section is one of the most common operations performed nowadays. The caesarian rate in the United States of America has been increasing over a decade to a present peak of few percentages. Although maternal mortality from caesarian section is low, it is still higher than from vaginal delivery. Further, the morbidity from infections, wound dehiscence, thrombotic events as well as recovery time is greater than that of vaginal delivery.

The most common signal for primary caesarian section is that of failure to progress in labor. Failure to progress can be caused by some

problems. If the pelvis is too small or the fetus is too large depending on the viewpoint taken, the diagnosis is Cephalopelvic Disproportion, which leads to failure to progress. If the uterus simply does not generate enough pressure during contraction, labor can stall and lead to failure to progress. If labor seems to be stalling, there are a number of measures that can be taken to augment it. Usually, two hours without cervical change in the setting of adequate uterine contractions in the active phase of labor was deemed failure to progress or active phase arrest, often leading to caesarian delivery. However, a recent study recommends that it is reasonable to wait up to four hours for cervical stage in the active phase of labor leading to a vaginal delivery in the majority of these patients.

Other common signals for primary caesarian section are breech presentation, abruption of placenta, status of fetus, fetal intolerance of labor, prolonged second stage, active herpes lesions, or failed operative vaginal delivery. The most common signal for caesarian section is a previous caesarian section.

cesarean deliveryReasons for a Caesarian Section – Some reasons which necessitate caesarian delivery are indicated here:

  • A cervical tumor may impede the process of delivery, making a caesarian section necessary.
  • If the head of the baby has become enlarged because of the presence of excessive fluids in the skull, the fluids may have to be let out by puncturing the scalp, or alternatively, delivery has to be effected by caesarian section.
  • The arm of the baby may sometimes protrude through the cervix along with the head. In such a condition, caesarian section becomes inevitable.
  • Sometimes the baby lies in a transverse position in the uterus, instead of the normal head down position. If the baby cannot be manipulated into the normal position, it becomes necessary to affect delivery by caesarian section.

In addition to the above reasons, if the pelvic bones of the mother are too narrow, or her general condition of health as unfavorable to a normal vaginal delivery, or if she has high blood pressure, or she has previously has a caesarian section, or if the baby is getting asphyxiated in the womb for some reason, caesarian section must be resorted to.
