Study summary

The routine assessment of fluid status depends on clinical evaluation and invasive monitoring. The clinical assessment lacks objectivity and the invasive monitoring carries risks. Point of care ultrasound (POCUS) parameters can be useful as early markers of fluid status and were used in safe fluid assessment in term pregnancy and preeclampsia.

Read the detailed description

Fluid therapy in preeclamptic patients presents a challenge. volume expansion may precipitate pulmonary edema while fluid restriction may worsen renal function and may aggravate post-spinal hypotension during cesarean section.

Pre-eclampsia predisposes to maternal mortality. It presents a serious hypertensive disorder during pregnancy which may progress rapidly to serious complications, including the death of both mother and fetus The optimal fluid management strategy constitutes a cornerstone in the management. The Royal College of Obstetricians and Gynecologists (RCOG) guidelines for severe pre-eclampsia recommend restrictive fluid therapy, in keeping with the absence of evidence favoring volume expansion. Restrictive management is advocated by The Society of Obstetric Medicine of Australia and New Zealand (SOMANZ) with additional fluid administration only recommended before intravenous hydralazine, regional anesthesia, immediate delivery, or in oliguric patients where a volume deficit is suspected.

Overall, limited evidence exists regarding the effectiveness of ultrasound assessment of the IVC collapsibility index to guide pre-operative fluid management in critically ill pre-eclamptic patients. A meta-analysis stated that few research trials are available in the obstetric population. Some studies suggest that it can accurately predict fluid responsiveness, but others argue that it may not be helpful.

Our trial is the first trial that compares the efficacy of IVCCI-guided perioperative fluid therapy against standard fluid therapy guided by clinical parameters in critically ill pre-eclamptic patients.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    IVCCI-guided fluid therapy

    the participants in this group will receive crystalloids according to the IVCCI assessment as follows: 1. If ≥ 50 % a bolus will be given 300 ml by dripping within 30 minutes, the fluid will be repeated by half the amount if needed to reach equal or less than 40% collapsibility. 2. If \< 50 % or B line finding in lung ultrasound no bolus will be given.

    Other: fluid therapy, 300 ml of crystalloid Ringer's solution.

  • No intervention
    Conventional fluid therapy

    the participants in this group will receive the standard regimen; no routine additional fluid within half an hour before surgery only the fixed maintenance of 80-100 ml/hr.

Interventions

  • Otherfluid therapy, 300 ml of crystalloid Ringer's solution.

    300 ml by dripping within 30 minutes, the fluid will be repeated by half the amount if needed to reach equal or less than 50% collapsibility. the fluid that will be used is sterile Ringer's solution which is an isotonic intravenous solution with pH 5.0 - 7.5 and an osmolality of 308mOsmol/kg.

What researchers measure

Primary outcomes

  1. post-spinal hypotension

    post-spinal anesthesia and early intraoperative (0-20 min) hypotension (MAP \< 65 mmHg and/or ≥ 20% decrease from baseline. Measured by the occurrence or not of hypotension. The aggregation method will be according to the distribution of data if normal mean and SD will be used.

    Time frame: 20 minutes after the spinal anesthesia injection

Secondary outcomes

  1. occurrence of complication

    occurrence of any complications such as pulmonary edema, need for intraoperative vasopressors.

    Time frame: from spinal anesthesia till the delivery of the fetus, or within 30 minutes postspinal which comes first

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2024 (actual). Primary completion is estimated for Nov 2024, 3 months after the start.

Of 171 non-industry interventional studies with no phase under Pre-Eclampsia, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 43. This study's planned 3 months is below that.

Counting every sponsor, half of 176 studies reached it within 24 months; a quarter within 9 and three quarters within 43.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
