A G3 female with a history of 2 previous second-trimester abortions presents at 22 weeks of gestation with funneling of the cervix and a cervix length of 20 mm. The most appropriate management would be?

1. A

   Apply Fothergill stitch

2. B

   Apply cervical cerclage

3. C

   Administer dinoprostone and bed rest

4. D

   Administer misoprostol and bed rest

Explanation

Listen in Hindi

• The patient's clinical picture—a history of recurrent second-trimester losses combined with ultrasound evidence of a short (20 mm) and funneled cervix at 22 weeks—is a classic presentation of cervical insufficiency.
• Cervical cerclage is a surgical procedure that places a stitch around the cervix to provide mechanical support and prevent premature dilation and preterm birth.
• Given the gestational age and findings, an ultrasound-indicated or rescue cerclage is the standard of care to prolong the pregnancy and improve fetal viability.

Why Other Options Were Wrong

• Option A: The Fothergill stitch is part of the Manchester repair, a surgical procedure for uterine prolapse, which is a different gynecological condition. It is not used to manage cervical insufficiency during pregnancy.
• Option C: Dinoprostone is a prostaglandin used to ripen the cervix and induce labor or terminate a pregnancy. Administering it would be counterproductive and harmful, as it would promote further cervical dilation and contractions.
• Option D: Misoprostol, like dinoprostone, is a prostaglandin that causes cervical ripening and uterine contractions. It is contraindicated in this scenario as the goal is to maintain the pregnancy, not terminate it.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Management of Cervical Insufficiency as background academic context rather than a clinical decision trigger.
• A key nursing role is patient education after a cerclage procedure. The patient must be taught to recognize and report signs of preterm labor (contractions, pelvic pressure), membrane rupture (gush of fluid), and infection (fever, foul-smelling discharge).
• Nurses are responsible for monitoring the patient post-procedure for uterine activity, fetal heart rate, vaginal bleeding, and leakage of amniotic fluid.
• What if the patient presented with a fever, uterine tenderness, and a foul-smelling discharge along with the cervical changes? In that case, chorioamnionitis (infection) would be suspected, which is a contraindication for cerclage. The management would shift to delivery to prevent maternal sepsis, regardless of gestational age.

How to Approach the Question

• First, analyze the patient's history and clinical data in the stem. Note the key elements: G3, two prior second-trimester losses, 22 weeks gestation, cervical length of 20 mm, and funneling.
• Synthesize these findings to arrive at a diagnosis. The combination of recurrent mid-trimester loss and current cervical changes strongly indicates cervical insufficiency.
• Next, evaluate each option based on this diagnosis. Ask yourself, 'Which of these interventions treats cervical insufficiency by supporting the cervix to maintain pregnancy?'
• Eliminate options that are for different conditions (Fothergill stitch) or that would have the opposite of the desired effect (prostaglandins like dinoprostone and misoprostol).
• This process will lead you to cervical cerclage as the only logical and appropriate management.

Concept Tested & Keywords

• Concept Tested: Management of Cervical Insufficiency
• Stem keywords: second-trimester abortions, 22 weeks gestation, funneling of the cervix, cervix length of 20 mm
• Lead-in keywords: most appropriate management
• Clinical cues: History of 2 previous second-trimester abortions: This is a major risk factor and a classic historical indicator for cervical insufficiency.
• Clinical cues: Cervix length 20 mm with funneling: This is a key ultrasound finding that confirms cervical weakness and an increased risk of preterm birth.
