Final answer:
To manage an incompetent cervix, cerclage is the primary intervention, stitch reinforcement of the cervix along with modified activity levels to reduce pressure on the cervix.
Step-by-step explanation:
For a patient with a history of an incompetent cervix, also known as cervical insufficiency, proactive management is essential to prevent preterm labor and other complications during pregnancy. The primary intervention technique is a procedure known as cerclage, which involves placing a stitch around the cervix to reinforce it and prevent premature dilation. This procedure is typically done during the second trimester of pregnancy. Additionally, the patient should be advised to reduce physical activity and avoid heavy lifting to minimize pressure on the cervix.
Regular prenatal visits are crucial for monitoring the cervix's length through ultrasound examinations. If signs of premature cervical changes are detected, it may necessitate additional interventions, such as the administration of progesterone supplements or modification of cerclage. Close observation and prompt treatment of any symptoms that suggest preterm labor are also important.
