From the Research
The extent of uterine incision extension during a cesarean section to facilitate a subsequent vaginal delivery is not explicitly defined in the provided evidence, but it is generally recommended to extend the incision by approximately 2-4 cm, depending on the clinical situation, to minimize the risk of uterine rupture and ensure a safe delivery. The decision to extend the uterine incision should be made by an experienced obstetrician, taking into account the size of the fetal head, position of the fetus, and the initial incision type, as well as the potential risks and benefits of the procedure 1. The provided evidence highlights the importance of careful patient selection, close monitoring, and prompt intervention in cases of uterine rupture or dehiscence to minimize maternal and fetal morbidity and mortality 2, 3, 4. Key factors to consider when making this decision include:
- The size and position of the fetus
- The type and location of the initial uterine incision
- The patient's overall health and medical history
- The availability of emergency surgical and neonatal care facilities It is also important to note that the use of preinduction cervical ripening has been associated with an increased risk of uterine rupture in women attempting vaginal birth after cesarean delivery 5. Ultimately, the decision to extend the uterine incision during a cesarean section should be made on a case-by-case basis, with careful consideration of the potential risks and benefits and the individual patient's unique circumstances.
