PVI Based Intraoperative Fluid Management in Head and Neck Free Flap Reconstructive Surgeries

April 13, 2017 updated by: DR ITEE CHOWDHURY, Rajiv Gandhi Cancer Institute & Research Center, India

Pleth Variability Index Based Intraoperative Fluid Management in Head and Neck Free Flap Reconstructive Surgeries

Intraoperative fluid given according to BMI in group B and according to pulse oximeter- derived pleth variability index(MASIMO RAINBOW PULSE CO OXIMETRY) in group G. Comparison of haemodynamics, urine output,blood lactate levels, blood sugar, flap sugar and coagulation profile between the two groups.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

A sample size of 80 taken and computer generated random allocation done to divide the patients in two groups(40 each). Head and neck onco surgery patients undergoing resection and reconstruction with radial artery free flap and antero lateral thigh free flap of duration 4-6 hours taken for surgery.

Group B to receive intravenous fluid according to body weight stating at the rate 6-8 ml/kg/hr.

Group G to receive intravenous fluid according to Pleth variability index value(4-11).Blood loss up to 10% replacement by colloids.

Comparison of following parameters:

Demography, haemodynamics,urine output .blood lactate, ph, oxygenation index ,thromboelastography (TEG), blood sugar, flap sugar .

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
80

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

25 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Group B

Group B- intervention -Body weight guided Intraoperative fluid administered @ 6-8 ml/kg and blood loss replacement with colloid.

hourly urine output if less than 0.5ml/hr 100-200ml bolus of plasmalyte was administered.
Other: Group B- Body weight guided intravenous fluid @6-8ml/kg
Intravenous fluid @6-8ml.kg and blood loss replacement with colloids maintaining urine output of 0.5ml/kg
Active Comparator: Group G
Group G- intervention - PVI( Masimo co oximeter) guided fluid therapy.
Other: Group G -PVI( Masimo co oximeter) guided fluid therapy

goal directed fluid therapy maintaining pvi 4-11. when pvi<4 fluid rate is 50-60ml/hr and pvi>11 200ml colloid bolus transfusion till pvi value achieves normal range.

In the control group crystalloid was administered @ 6-8 ml/kg and blood loss was replaced by colloids. Hourly urine output was measured and if less than 0.5ml/hr bolus crystalloid 100-200ml was administered

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in TEG waveform tracing as obtained from TEG 5000 Hemostasis analyser system
Time Frame: six months
The investigators hypothesize that the patients in group G receiving PVI (pleth variability index) guided fluid therapy will have normal TEG parameter (R,K, ALPHA, MA and LY30) values and the patients in group B may have abnormal TEG parameter values.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2016

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
