Emergency cesarean delivery in induction of labor: an evaluation of risk factors

Abstract

Women with a previous cesarean delivery, nulliparous, short, and obese women with induced labor are at high risk of a cesarean delivery. When there is a need to deliver a woman with a previous cesarean section or a nulliparous woman with other risk factors for cesarean delivery, it may be prudent to consider an elective cesarean section.

Risk Factors for Cesarean Delivery after Induction of Labor in Nulliparous Women with an Unfavorable Cervix at or beyond 41 Weeks of Gestation

“…Short maternal height was previously reported as a risk factor for CS and shoulder dystocia, likely due to cephalopelvic disproportion (CPD) [27,28,29]. In addition, a large BPD of the newborn was associated with CPD [30].…”

“…A previous report demonstrated that PROM is a major risk factor for the failure of labor to progress during the first stage [27]. However, few studies report on the effect of early ROM on the course of labor.…”

Risk Factors for Cesarean Delivery in Preterm, Term and Post-Term Patients Undergoing Induction of Labor with an Unfavorable Cervix

“…Most studies focus solely on term patients [10][11][12][13][14] , while others evaluate only patients undergoing elective induction [3,10,11] . Multiple studies have confirmed that induction itself increases the risk of cesarean and that a low Bishop's score is a risk factor for cesarean when induction is undertaken.…”

Prepartum and intrapartum caesarean section rates at Mater Mothers’ Hospital Brisbane 1997–2005

“…10,11 The many reasons cited for increasing CS rates include maternal, fetal variables and intrapartum events. [12][13][14][15][16][17][18][19][20][21][22][23][24] However, medical reasons alone form an inadequate explanation of this upward trend, as with determined efforts, CS rates can be maintained at a constant level or even reduced without an apparent increase in morbidity. 25,26 The current absence of a clear understanding of the pressures which drive this phenomenon results in a need to clearly document the existing situation and to partition the influences into known versus unknown.…”
