Internal jugular vein collapsibility to gauge volume status in preeclampsia vs. normal pregnancy

Official title: Internal Jugular Vein Collapsibility Index for Volume Status Assessment in Preeclampsia in Correlation With Normotensive Parturients: a Prospective Observational Cohort Study

Run by Tanta University · NCT07786246 · Data updated 2026-11-12

This study tests whether ultrasound of the internal jugular vein can show differences in fluid status between preeclamptic pregnant people and those with normal blood pressure during planned cesarean delivery.

Is this trial a fit for you?

Likely a good fit

Singleton pregnant individuals aged 18–40, 28–40 weeks gestation, either normotensive or newly diagnosed preeclamptic, scheduled for elective cesarean section with neuro-axial anesthesia.

Probably not a fit

Pregnant patients not fitting the imaging or gestational criteria or those with contraindications to ultrasound assessment may not benefit from this approach.

What this trial studies

This observational study compares intravascular volume indicators obtained from internal jugular vein ultrasound between preeclamptic and normotensive parturients at 28–40 weeks undergoing elective cesarean section. It aims to identify non-invasive, bedside measures that reflect volume status and contrast them between the two groups. The approach seeks to improve perioperative fluid guidance and reduce risks related to hypovolemia or fluid overload in preeclampsia. The study notes limitations of invasive monitoring and challenges of ultrasound in pregnancy, proposing IJV indices as a practical alternative. No interventional manipulation is described; data collection centers on imaging-based measurements and clinical correlations.

Why it matters

Potential benefit: If successful, the approach could provide a simple, non-invasive way to tailor fluid therapy for preeclamptic patients during cesarean delivery.

How similar studies have gone: Non-invasive ultrasound methods for volume assessment have been explored, with mixed results in preeclampsia; this study applies IJV collapsibility specifically in this context.

Inclusion Criteria:

1. Singleton parturients from 18 to 40 years old.
2. Either normotensive or preeclamptic parturients scheduled for elective cesarean section under neuro-axial block matched for gestational age 28-40 weeks will be included:
3. Normotensive group: uncomplicated normotensive pregnancy with systolic blood pressure below 140 mmHg and diastolic blood pressure below 90mmHg without proteinuria.
4. Preeclamptic Group: new onset preeclamptic pregnant female with gestational hypertension after 20 weeks of pregnancy diagnosed based on ISSHP Guidelines: systolic blood pressure ≥140 mmHg and/or a diastolic blood pressure ≥90 mmHg, accompanied by one or more of the following:

   * Proteinuria (≥300 mg in a 24-hour urine sample)
   * Alb/Cr ratio ≥30 mg/mmol,
   * Organ dysfunction (renal insufficiency (creatinine level\>1.1mg%), liver involvement (liver enzyme levels ≥3 times normal), neurological complications (Headache and blurring of vision) and hematological involvement (thrombocytopenia\<100.000)).

Exclusion Criteria:

1. Parturients with pre-existing cardiac \& vascular disease affecting blood volume and vascular compliance: (Valvular or congenital heart disease, arrhythmia, previous history of venous thromboembolism, chronic kidney disease, gestational diabetes).
2. multiple gestations
3. known thyroid disorders or chronic hypertension
4. patients with BMI \>40 and patients requiring emergency delivery.
