Cesarean Section

Core Concepts

Indications: why cesarean?

Indications group into three baskets. Maternal: placenta previa (placenta covering the cervical opening), prior classical uterine incision, some uterine surgeries, and maternal conditions where labor is unsafe. Fetal: nonreassuring fetal status that does not improve, malpresentation (breech, transverse lie), umbilical cord prolapse, and suspected macrosomia in some circumstances. Labor-related: cephalopelvic disproportion, arrest of dilation or descent, failed induction, and failed operative vaginal delivery. Many cesareans result from a combination — for example, a macrosomic fetus with a stalled second stage. The decision is the provider's, made with the client whenever time allows; the nurse's role is to support the decision-making process with current, accurate information and a listening ear.

Incision types: skin vs. uterus

The skin incision (usually low, along the bikini line — a Pfannenstiel incision, or a vertical midline incision in some situations) is not the part that matters most. What matters for the future is the uterine incision. The low transverse incision (across the lower uterine segment) is the most common: it heals well and is compatible with a future trial of labor after cesarean in appropriate candidates. The low vertical incision runs vertically in the lower segment. The classical incision runs vertically through the upper, muscular part of the uterus; it is reserved for specific situations (very preterm fetus, certain placental or fetal positions) because it carries higher rupture risk in future pregnancies — which is why a classical incision typically rules out a future trial of labor. Nurses must know which incision a client has: it drives postpartum assessment and future-pregnancy counseling.

Anesthesia: regional vs. general

Most cesareans use neuraxial (regional) anesthesia — spinal, epidural, or combined — which numbs from the chest down while the client stays awake and can meet the newborn immediately. General anesthesia is used for emergencies (no time for regional), contraindications, or client preference/clinical need; it means the client is unconscious and the newborn needs immediate assessment after birth. The anesthesia plan changes the nursing care: awake clients need continuous emotional support and updates; anesthetized clients need extra attention to airway, positioning, and temperature.

The perioperative nursing role: before

Preoperative nursing care includes: education and consent support (explaining what will happen, when she'll see the newborn, what recovery will feel like); verifying fasting status per policy; reviewing ordered labs and fetal assessment; starting IV access and administering ordered medications (e.g., antibiotics per orders); placing a urinary catheter; and preparing the newborn team and warmer. In an emergency cesarean, this list compresses dramatically — the nurse works in parallel with the team, communicating constantly.

The intraoperative role

Inside the OR the nurse is the coordinator: positioning the client safely (left tilt to keep the uterus off the great vessels, a padded, secured position), performing surgical counts with the team, documenting, monitoring the client's status and the newborn's birth time and condition, and facilitating immediate newborn care and skin-to-skin contact when the client is stable and awake. The circulating nurse is the client's advocate in the room — the one who speaks for her when she cannot.

Postoperative care and recovery

After surgery the client goes to recovery, then to the postpartum unit. Nursing care centers on: frequent vital signs and bleeding assessment (fundus, lochia, incision — remembering the surgical route does not exempt her from postpartum hemorrhage risk); pain management (incisional pain plus afterpains); early mobility and thromboembolism prevention per protocol; incision care and infection watch; voiding (the catheter is removed per orders; output must be monitored); nutrition (advancing diet as ordered); breastfeeding support (positioning around the incision); and emotional support — a cesarean can feel like a loss of the planned birth experience, and that deserves acknowledgment, not dismissal.

Complications to watch

The nurse's surveillance list: postpartum hemorrhage (uterine atony is still possible), infection (endometritis, wound infection — fever, odor, erythema, drainage), venous thromboembolism (leg pain/swelling, chest symptoms), ileus (abdominal distention, no bowel sounds, nausea), and anesthesia complications (nausea, headache after neuraxial block, respiratory issues after general). Early, specific reporting is the nursing intervention that matters most — complications are caught at the vital-signs-and-assessment level before they are caught by any machine.

TOLAC and VBAC: the next pregnancy

TOLAC (trial of labor after cesarean) is the attempt at vaginal birth after a prior cesarean; VBAC (vaginal birth after cesarean) is its successful result. Candidates are chosen carefully — the type of prior incision (low transverse is generally favorable), the reason for the prior cesarean, the current pregnancy's conditions, and the facility's ability to respond to a uterine rupture emergency. TOLAC is a shared decision made with full information: it offers the benefits of vaginal birth and carries a small risk of uterine rupture, while repeat cesarean carries surgical risks. Institutional policies vary — some facilities support TOLAC, some do not — and the nurse should know her facility's resources and support the client's informed choice.
