Indications for Caesarian Section for Delivery

Maternal Indications

• The American College of Obstetricians and Gynecologists recommends C-section for women with severe pulmonary hypertension, significant aortopathy, and maternal cardiac instability, such as acute heart failure, to prioritize maternal and fetal outcomes 1, 2
• Women on anticoagulation therapy, such as warfarin, should undergo C-section to minimize the period off anticoagulation and reduce the risk of maternal valve thrombosis 1, 2
• C-section is associated with improved maternal and perinatal outcomes in women with acute fatty liver of pregnancy (AFLP) 3
• Immediate C-section delivery should be considered in life-threatening maternal complications, such as cardiac arrest, to improve maternal outcomes 1
• In the event of maternal cardiac arrest, C-section delivery should occur within 5 minutes to optimize both maternal and fetal outcomes 1

Fetal Indications

• Fetal distress with irreversible causes, including major placental abruption, fetal hemorrhage, and umbilical cord prolapse with sustained bradycardia, requires immediate C-section delivery to improve fetal outcomes 4

Special Considerations

• Women with anticipated difficult airways should undergo elective C-section to avoid emergency general anesthesia 5
• C-section may be a safer alternative for women with hepatitis C and high viral load to reduce the risk of vertical transmission 3
• Multidisciplinary planning, including obstetricians, anesthesiologists, and relevant specialists, is essential for women with complex medical conditions to develop individualized delivery plans 1, 5

Risks and Considerations

• C-section carries a higher risk of long-term complications, including chronic wound pain, placenta previa, and accreta in subsequent pregnancies, and venous thromboembolism 6

Anesthetic Considerations

• Regional anesthesia, such as spinal or epidural, is recommended over general anesthesia for most C-sections 7
• General anesthesia can precipitate uncontrolled hypertension in women with preeclampsia and carries higher maternal risks 3
• The 20-30° head-up position can improve functional residual capacity, laryngoscopic view, and reduce gastroesophageal reflux when general anesthesia is required 8, 4

Common Pitfalls to Avoid

• Inadequate preparation, including failure to have a multidisciplinary team and appropriate equipment readily available, can lead to poor outcomes in high-risk cases 1, 4
• Delayed decision-making in cases of true fetal distress with irreversible causes can result in worse neonatal outcomes 4
• Overlooking maternal cardiac status can lead to poor outcomes, and women with cardiac disease require careful hemodynamic monitoring and management during delivery 1, 2

Indications for Cesarean Section Delivery

Maternal and Fetal Complications

• HELLP syndrome is a severe complication of pregnancy characterized by Hemolysis, Elevated Liver enzymes, and Low Platelets, often requiring expedited delivery 9
• Cesarean section is associated with improved maternal and perinatal outcomes in women with severe pregnancy-related liver complications like HELLP syndrome 9
• The American College of Obstetricians and Gynecologists recommends scheduled cesarean delivery for women with HIV-1 RNA >1,000 copies/mL near the time of delivery, regardless of the type of antiretroviral therapy the woman is receiving 10, 11, 12
• The U.S. Public Health Service Task Force supports the recommendation for scheduled cesarean delivery for women with HIV-1 RNA >1,000 copies/mL near the time of delivery 10, 12
• Elective cesarean section should be performed at 38 completed weeks of gestation, based on the best clinical estimate of gestational age 12
• The American College of Obstetricians and Gynecologists recommends intravenous zidovudine to be started at least 3 hours before the cesarean operation for women with HIV 12
• The woman's prenatal antiretroviral regimen should not be interrupted around the time of delivery, as recommended by the American College of Obstetricians and Gynecologists 12
• Prophylactic antibiotics should be administered to reduce the risk of postpartum infection in women undergoing cesarean section, as recommended by the U.S. Public Health Service Task Force 13
• Performing unnecessary cesarean sections increases maternal risks, including postpartum infections, which are five to seven times more common after cesarean section compared with vaginal delivery 10, 11

Cesarean Section Delivery Indications and Considerations

Fetal Indications

• Fetal growth restriction with abnormal Doppler studies or other concerning features is an indication for cesarean section delivery, as recommended by the American College of Obstetricians and Gynecologists 14

Mode of Delivery Considerations

• For early-onset fetal growth restriction with absent or reversed end-diastolic flow in umbilical artery, cesarean section is recommended by 32-34 weeks, according to the American College of Obstetricians and Gynecologists 14, 15
• Abnormal fetal surveillance, such as abnormal cardiotocography (CTG) or ductus venosus Doppler, is an indication for cesarean section delivery, as recommended by the American College of Obstetricians and Gynecologists 14

Surgical Technique Considerations

• The standard approach for cesarean section involves a transverse lower uterine segment incision, as recommended by the American College of Obstetricians and Gynecologists 16
