Fluid Management Surgical Patients in Intensive Care Unit.

March 17, 2021 updated by: ICU, National Hepatology & Tropical Medicine Research Institute

Fluid Management Guided With Lactate Clearance Versus Central Venous Oxygen Saturation Monitoring in Surgical Patients in Intensive Care Unit.

The aim of this study is to evaluate the efficacy of lactate clearance (LCR) versus central venous oxygen saturation (ScVO2) to guide fluid management for post-operative patients in the intensive care unit (ICU).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Sixty patients will be randomly assigned in a 1:1 manner into two groups; (group A= thirty patients = ScVO2) & (group B = thirty patients =lactate clearance). Fluid therapy will be initiated in each group with maintenance in the form of crystalloid e.g. Ringer or Ringer acetate (in a dose of 30-35 ml/Kg/day) plus replacement with crystalloid e.g. Ringer, Ringer acetate or saline 0.9%, 500 ml over 10-30 min. that will be administered in boluses [7] guided by ScVO2with target value ≥ 70% versus lactate clearance (LCR) with target value ≤ 2mmol/L (or decline ≥ 10%) by the end of the study in group A & group B respectively with close regular clinical monitoring/30min., CVP limits 12-16 cmH2O & mean arterial pressure (MAP) 65-90mmHg. Maintenance fluid without replacement will be initiated alone if ScVO2 or lactate value normalized or are normal from the start.

All demographic data will be obtained including the patients' age, sex, body mass index (BMI), associated co-morbidities (diabetes mellitus &hypertension), Sequential Organ Failure Assessment (SOFA) on admission & discharge from ICU, duration of surgery, the type of surgery, the amount of blood loss intraoperative, the amount of blood transfused intraoperative, the need&the amount of blood transfusion postoperative & will be recorded.

Follow-up hemodynamics including the heart rate, mean arterial pressure (MAP), CVP, arterial oxygen saturation (SaO2), urine volume, fluid balance, blood gases (base excess, PH), hypoxic index (PaO2/FIO2 ratio) & total fluid infused as a baseline then followed as required. Monitoring of either lactate level or ScVO2 on admission followed and recorded at regular intervals during treatment on 0, 2, 6, 12, 24 & 48hours.

Laboratory investigations including the complete blood profile, prothrombin time, liver functions, serum creatinine & serum electrolytes will be assessed at randomization as a baseline & then will be recorded as required. Postoperative medical or surgical morbidities will be followed during ICU & hospital stay e.g. weight gain, impairment of hypoxic index (P/F ratio), pulmonary edema, pleural effusion, need for mechanical ventilation, paralytic ileus, renal impairment& intra-abdominal bleeding.28-day mortality will be asked for & followed by calling the telephone number of the patient or one of his/her first-degree relatives.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients who are admitted to the intensive care unit of National Hepatology & Tropical Medicine Research Institute (NHTMRI) post intra-abdominal surgical intervention.

Exclusion Criteria:

  • Patients will be excluded from the study if they have severe liver impairment (child-Pugh C15), septic shock or hemodynamic instability requiring high dose circulatory support e.g. > 2ug/min noradrenaline as it will impair lactate clearance &/or central venous oxygen saturation normalization, advanced heart failure, central venous pressure (CVP) ≥ 18cmH2O as it will limit fluid therapy, severe hypothermia (< 28◦ C) as it will induce lactate production.
