Informed Consent for Cesarean Section (Cesarean Delivery)

Patient and Obstetric Information

Nature and Purpose of the Procedure

Cesarean section is a surgical procedure in which the baby is delivered through incisions made in the abdominal wall and uterus. The procedure is performed under regional anesthesia (spinal or epidural block, which numbs from the chest down while keeping the patient awake) or, in emergencies, general anesthesia. A transverse (horizontal) skin incision (Pfannenstiel incision) is made above the pubic hairline, and the uterus is opened with a low transverse uterine incision in most cases. The baby and placenta are delivered, and the uterus and abdominal layers are closed with sutures. The operation typically takes 30 to 90 minutes. Classic vertical uterine incisions may be required in certain situations (extreme prematurity, abnormal fetal position, lower segment fibroids) and have implications for future pregnancy management.

Anesthesia Options and Disclosure

The preferred anesthesia for cesarean section is regional anesthesia (spinal block or epidural) which numbs the lower body while you remain fully awake and able to see and hold your baby after delivery. Regional anesthesia avoids the risks of general anesthesia including difficult airway, aspiration, and neonatal sedation. General anesthesia is used when: regional anesthesia fails or is contraindicated; in life-threatening maternal emergencies where the speed of onset of regional block is insufficient; or at patient request in specific circumstances. The anesthesiologist will discuss the anesthesia plan with you separately and obtain your consent for anesthesia.

Material Risks and Potential Complications

Hemorrhage and blood transfusion: cesarean section is associated with greater blood loss than vaginal delivery. Severe postpartum hemorrhage requiring blood transfusion occurs in approximately 3 to 5 percent of cesarean deliveries. Uterotonic agents (oxytocin, carboprost, misoprostol) will be used routinely to minimize blood loss.
Bladder and ureter injury: the bladder is adherent to the lower uterine segment, particularly in repeat cesareans with prior adhesions. Bladder injury occurs in approximately 0.3 percent; ureteral injury is rare (0.01 percent). Bladder injuries are usually recognized and repaired intraoperatively.
Bowel injury: inadvertent injury to the bowel, particularly in cases with extensive adhesions from prior surgery. Rare; requires intraoperative or delayed surgical repair.
Wound infection: superficial wound infection or seroma in 3 to 8 percent; deep wound infection or dehiscence in 1 to 2 percent. Risk is higher in obese patients, diabetics, and those with prolonged labour before cesarean.
Venous thromboembolism (DVT/PE): cesarean section carries a 3 to 5 times higher DVT risk than vaginal delivery. Prophylactic low-molecular-weight heparin (LMWH), compression stockings, and early mobilization are routinely used.
Placenta accreta spectrum (future pregnancy): each cesarean creates uterine scar tissue. With each subsequent cesarean, the risk of abnormal placental implantation (placenta accreta, increta, or percreta) increases substantially, and may require hysterectomy at the time of the subsequent cesarean to control catastrophic hemorrhage.
Uterine rupture in future pregnancy: a low transverse uterine incision scar carries a 0.5 to 1 percent risk of uterine rupture during a subsequent labour (vaginal birth after cesarean, VBAC); a classical vertical uterine incision carries a substantially higher rupture risk (4 to 9 percent) and is a contraindication to future labour.
Neonatal respiratory distress: babies delivered by elective cesarean before labour are at higher risk of transient tachypnea of the newborn (TTN) due to retained lung fluid. A neonatal team will be present at delivery to assess the baby.

Implications for Future Pregnancies

This cesarean delivery creates a uterine scar that has important implications for future pregnancies. You should discuss with your obstetrician: (1) The number of cesareans you have had and the cumulative risk of placenta accreta spectrum; (2) Whether vaginal birth after cesarean (VBAC) may be appropriate for a future pregnancy; (3) The recommended interpregnancy interval (typically at least 18 months from delivery to conception of the next pregnancy) to allow uterine scar healing and reduce the risk of uterine rupture. You will be given written information on these risks as part of your discharge documentation.

Alternatives to Cesarean Section

Vaginal delivery (where clinically appropriate): depending on your indication, the risks and benefits of a trial of labour have been discussed with you. In planned repeat cesarean, the option of VBAC (vaginal birth after cesarean) may be appropriate for selected patients.
Assisted vaginal delivery (forceps or vacuum): in selected situations of second-stage arrest, assisted vaginal delivery may avoid cesarean. Your obstetrician will advise if this is applicable.

Expected Benefits

The primary expected benefit is safe delivery of your baby in a situation where vaginal delivery carries unacceptable risk to you or the baby, or when surgical delivery is clinically indicated. In planned repeat cesarean, the procedure eliminates the risk of uterine rupture during labour. In emergency situations, cesarean section may be life-saving for the mother, the baby, or both.

Right to Refuse or Withdraw Consent

You have the right to refuse cesarean section. In non-emergency situations, your obstetrician will discuss the clinical implications of refusing the procedure. In life-threatening emergencies (e.g. Category 1 cesarean for non-reassuring fetal heart rate and imminent fetal compromise), delaying the procedure may result in serious harm to the baby or yourself. If you are unable to consent in a genuine emergency, the procedure will be performed to preserve life in accordance with professional and legal standards.

Questions and Understanding Confirmation

I confirm that the indication for cesarean has been explained to me, along with the implications for future pregnancies and the risks of placenta accreta spectrum with repeated cesareans. All my questions have been answered to my satisfaction.

Copy of Consent Acknowledgment

I acknowledge that I have been offered a signed copy of this informed consent form for my own records.

Patient Authorization

I have been informed of the cesarean section procedure, its expected benefits, the material risks listed above, the implications for future pregnancies, and the available alternatives. I consent to cesarean delivery and authorize the obstetrician to perform any additional procedures necessary to ensure my safety and the safe delivery of my baby.
