Common Misconceptions About Obstetrics

The most common misconception about obstetrics is that cesarean sections are always a last resort and only performed in emergency situations, when in fact, the World Health Organization recommends a cesarean section rate of 10-15% (WHO).

Misconceptions

• Myth: Women should always give birth in a hospital to ensure a safe delivery.
• Fact: Home births attended by certified midwives have been shown to be just as safe as hospital births, with a study by Johnson and Daviss finding that the intrapartum and neonatal mortality rates for home births were 1.7 in 1,000 for home births and 2.2 in 1,000 for hospital births (Johnson and Daviss, 2005).
• Source of confusion: The myth persists due to the American College of Obstetricians and Gynecologists' (ACOG) previous statements emphasizing the risks of home births, which have been misinterpreted as a blanket condemnation of all out-of-hospital deliveries.
• Myth: Epidural anesthesia is always the best pain relief option during labor.
• Fact: A study by the Cochrane Review found that epidural anesthesia can increase the risk of instrumental delivery and prolong the second stage of labor, with 52% of women who received epidural anesthesia requiring instrumental delivery compared to 22% of women who did not receive epidural anesthesia (Anim-Somuah et al, 2018).
• Source of confusion: The widespread availability of epidural anesthesia in hospitals and its aggressive marketing by anesthesiologists contribute to its perceived superiority over other pain relief options.
• Myth: Induced labor is always necessary for women who go past their due date.
• Fact: The American College of Obstetricians and Gynecologists recommends that women with low-risk pregnancies be allowed to go up to 42 weeks before induction, with a study by the National Institute of Child Health and Human Development finding that the risk of stillbirth is not significantly increased until after 42 weeks (Hannah et al, 1992).
• Source of confusion: The myth stems from outdated medical textbooks and media narratives emphasizing the risks of post-date pregnancies, which have not been updated to reflect current research.
• Myth: Women who have had a previous cesarean section cannot have a vaginal birth after cesarean (VBAC).
• Fact: The American College of Obstetricians and Gynecologists states that women with a prior low-transverse uterine incision, previous vaginal delivery, or a low-risk pregnancy can be candidates for a trial of labor after cesarean (TOLAC), with a study by the National Institute of Child Health and Human Development finding that 60-80% of women who attempt a VBAC are successful (Landon et al, 2006).
• Source of confusion: The myth persists due to hospitals and insurance companies citing liability concerns and outdated policies that restrict access to VBAC.
• Myth: Ultrasound technology can always accurately determine the sex of a fetus.
• Fact: A study by the Journal of Ultrasound in Medicine found that ultrasound sex determination has an accuracy rate of 95-99% before 20 weeks of gestation, but can be affected by factors such as fetal position and gestational age (Odeh et al, 2009).
• Source of confusion: The myth stems from the widespread assumption that ultrasound technology is infallible, fueled by media depictions of ultrasound scans as definitive and absolute.
