Cesarean Section Procedure Steps
A cesarean section should be performed using the Joel-Cohen surgical technique with a Pfannenstiel incision, blunt expansion of the uterine incision, non-closure of the peritoneum, and subcuticular skin closure to optimize maternal outcomes. 1
Preoperative Preparation
- Administer prophylactic antibiotics within 60 minutes before skin incision
- First-generation cephalosporin (cefazolin 2g IV) for all patients
- Add azithromycin 500mg IV for women in labor or with ruptured membranes 1
- Perform abdominal skin cleansing with chlorhexidine-alcohol solution 1
- Consider vaginal preparation with povidone-iodine solution 1
- Administer intravenous dexamethasone after delivery (absent contraindications) 2
Anesthesia
- Neuraxial anesthesia is preferred for elective cesarean sections 1
- Add intrathecal morphine 50–100 μg or diamorphine 300 μg to spinal anesthesia 2
- Position patient supine with left lateral tilt (15-30 degrees) to prevent aortocaval compression 1
Surgical Procedure
Skin Incision
Abdominal Wall Entry
- Incise subcutaneous tissue and fascia
- Separate rectus muscles in the midline
- Bluntly dissect the peritoneum to enter the peritoneal cavity 1
Uterine Access
- Push bladder down to expose the lower uterine segment
- Make a transverse incision in the lower uterine segment approximately 2 cm above the vesicouterine fold 1
Delivery of Baby
Placental Delivery
- Allow spontaneous separation of placenta
- Apply gentle traction on cord with counter-pressure on uterine fundus
- Inspect placenta for completeness 1
Uterine Closure
- Close the hysterotomy in two layers to potentially reduce the risk of uterine rupture in subsequent pregnancies 1
- Ensure hemostasis of the uterine incision
Abdominal Closure
Postoperative Pain Management
- Administer paracetamol and NSAIDs regularly after delivery 2
- Consider local anesthetic wound infiltration, continuous wound local anesthetic infusion, or fascial plane blocks if intrathecal morphine is not used 2
- Use transcutaneous electrical nerve stimulation as an analgesic adjunct 2
- Apply abdominal binders to improve comfort 2
Special Considerations
- For preterm deliveries or difficult access to the lower uterine segment, a vertical hysterotomy (classical cesarean section) may be necessary 3
- For patients with portal hypertension, a median low abdominal skin incision may afford lower risks of hemorrhage 1
- For patients with gynecologic cancers, particularly cervical cancer, a corporeal uterine incision is recommended 1
Potential Complications
- Hemorrhage (4-6% risk with repeat cesarean sections)
- Infection (reduced with proper antibiotic prophylaxis)
- Bladder or bowel injury
- Venous thromboembolism (consider thromboprophylaxis with LMWH) 1
- Long-term risks include placenta accreta in future pregnancies (0.25-3% risk with multiple cesarean sections), uterine rupture in subsequent pregnancies, adhesion formation, and incisional hernia 1
By following these standardized steps with careful attention to anatomical layers, hemostasis, and gentle handling of tissues, maternal morbidity can be minimized and neonatal outcomes optimized.
