Brief Summary

Introduction: Pre-eclampsia is a multifactorial syndrome which occurs in hypertension and proteinuria in pregnant women over 20 weeks gestation. It is the leading cause of maternal complications such as pulmonary edema, which occurs in about 3% of severe preeclamptic having as one of the causes volume overload. Anesthetic procedures are frequent in this population, with replacement with crystalloid of the duct during cesarean section under spinal anesthesia for combat hypotension and hypovolemia manifested by oliguria. However, as water therapy have antagonistic effects on cardiopulmonary and renal systems is no doubt as to the benefits compared to conventional or restrictive pattern of fluid therapy on renal function. Objective: To compare the renal function of patients with severe preeclampsia who received restrictive fluid therapy during caesarean section, as well as evaluating the use of cystatin C and Neutrophil gelatinase-associated lipocalin (NGAL) as a predictor of renal damage in this population. Hypothesis: Intraoperative fluid restriction did not influence renal function of patients with severe preeclampsia undergoing cesarean section under spinal anesthesia.

Outcome Measures

Primary Outcomes (2)

  • Renal Function in Severe Preeclampsia With Restrictive Fluid Therapy

    Renal function evaluated through creatinine levels in three moments: preoperative, first and second postoperative days.

    preoperative, first and second day postoperative

  • Postoperative Renal Dysfunction Evaluated by the Acute Kidney Injury Network (AKIN) Index

    Renal dysfunction was stratified by the Acute Kidney Injury Network (AKIN) index in three stages, in terms of creatinine increase from baseline: stage 1 included an interval of 150-200%, stage 2 200%-300%, and stage 3 more than 300% or hemodialysis

    Postoperative renal dysfunction

Secondary Outcomes (6)

  • Neutrophil Gelatinase-associated Lipocalin (NGAL) as New Marker of Renal Injury in Preeclampsia

    preoperative, first and second day postoperative

  • Cystatin C as New Marker of Renal Injury in Preeclampsia

    preoperative, first and second day postoperative

  • Proteinuria in Severe Pre-eclampsia Submitted to Cesarean Section Under Different Regimes of Hydration

    Proteinuria in severe pre-eclampsia in in pre-operative and post-operative period

  • Platelets in Restrictive Fluid Management of Severe Preeclampsia

    preoperative, first and second day postoperative

  • International Normalized Ratio (INR) of Prothrombin Time (PT) in Restrictive Fluid Management of Severe Preeclampsia During Cesarean Section

    preoperative, first and second day postoperative

  • +1 more secondary outcomes

Other Outcomes (1)

  • Urine Output During Cesarean Section in Severe Pre-eclampsia

    urine output during cesarean section (an average of 60 minutes)

Study Arms (2)

Liberal Fluid therapy

NO INTERVENTION

The liberal group will receive 1500 mL of crystalloid solution during the cesarean section. This is the non-intervention arm once that 1500 ml of crystalloid is the amount usually used during caesarean.

Restrictive Fluid Therapy

ACTIVE COMPARATOR

The restrictive group will receive 250 mL of crystalloid solution during cesarean section.

Other: Restrictive Fluid Therapy

Interventions

The intervention in this randomized clinical trial is fluid restriction during cesarean section. The restricted group will receive 250 mL of crystalloid during surgery.

Restrictive Fluid Therapy
