Status and phase: Not yet enrolling; Phase 4

Conditions: Pre-Eclampsia

Treatments: Drug: Human Albumin (colloid); Drug: Lactated Ringer's Injection (crystalloid); Device: Edwards HemoSphere monitor with ClearSight-Acumen finger cuff

About

The purpose of this study is to compare the effect of albumin versus routine care on hemodynamic response and stability in pre-eclamptic patients during cesarean delivery. The hypothesis is that volume replacement with albumin guided by stroke volume variation (SVV) using a ClearSight-Acumen (CS-A) monitor, before cesarean delivery (CD), improves hemodynamic stability in preeclamptic patients with severe features compared to routine care, under neuraxial anesthesia.

Enrollment: 62 estimated patients

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Gestational age greater or equal to 24 weeks
• Diagnosis of preeclampsia with severe features [Pre-eclampsia is defined as high blood pressure after 20 weeks with or without proteinuria. Pre-eclampsia with severe features is defined as the presence of preeclampsia with any of the following features: severe hypertension (blood pressure ≥160/110 mmHg on two separate occasions); thrombocytopenia (platelet count <100,000 per microliter); impaired liver function (elevated liver transaminases to twice the normal concentration or severe persistent right upper quadrant or epigastric pain not responsive to medications); progressive renal insufficiency with a serum creatinine level of >1.1 mg/dl or doubling of the serum creatinine level in the absence of other renal disease; pulmonary edema or unexplained new-onset cerebral symptoms (headache) unresponsive to medications or visual disturbances.]
• Scheduled Cesarean Delivery
• Unscheduled Cesarean Delivery with the goal to proceed to the operating room within no less than 30 minutes due to concern for maternal or fetal status that is not immediately life threatening.
• Requiring Neuraxial Anesthesia (spinal or CSE)

Exclusion criteria

• Patient declines to participate in the study
• Labor
• Contraindications to the use of neuraxial anesthesia (coagulopathy, infection at the insertion site, intracranial mass etc.)
• Unscheduled Cesarean Delivery with the goal to proceed to the operating room immediately for delivery of the baby due to imminent/unavoidable threat to the life of the mother or fetus.
• The use of or conversion to General Anesthesia
• Non-reassuring fetal status including the presence of cardiac or multi-system anomalies, category III tracing etc.
• Significant maternal cardiopulmonary disease including pulmonary hypertension, ischemic heart disease with systolic dysfunction, pulmonary edema etc.
• Significant intraoperative events (such as hemorrhage) requiring administration of multiple blood products and ICU admission.

62 participants in 2 patient groups

Fluid restriction using crystalloid

Active Comparator group

Description:

Fluid restriction will be achieved with the crystalloid lactated ringer's injection administered at at a keep-the-vein-open (KVO) rate of 75 milliliters per hour (mL/hr).

Treatment:

Drug: Lactated Ringer's Injection (crystalloid)

Fluid replacement using colloid as guided by stroke volume variation (SVV)

Experimental group

Description:

Fluid replacement will be achieved with the colloid 5% albumin infusion. Use of colloid will be guided by stroke volume variation (SVV) as assessed by the Edwards HemoSphere monitor with ClearSight-Acumen finger cuff device.

Treatment:

Device: Edwards HemoSphere monitor with ClearSight-Acumen finger cuff

Drug: Human Albumin (colloid)
