Trial summary

Adequate and balanced fluid resuscitation is one of the cornerstones of intraoperative patient management. Over-resuscitation leading to positive fluid balance is associated with increased postoperative mortality and morbidity. Read more about this study

About this study

Official title: Investigation of the Effectiveness of Lung Ultrasonography in the Management of Intraoperative Fluid Therapy, Prospective Observational Study

Adequate and balanced fluid resuscitation is one of the cornerstones of intraoperative patient management. Over-resuscitation leading to positive fluid balance is associated with increased postoperative mortality and morbidity.

Invasive and non-invasive technologies can be used for the adequacy of intraoperative fluid therapy.

Lung ultrasonography (LUS) is a safe and accurate bedside imaging method. LUS, which is frequently used in the diagnosis of postoperative hypoxemia, has also begun to be preferred for fluid management in intensive care units.

Read the detailed description

In this study, we aimed to investigate the effectiveness of intraoperative LUS data in the control of fluid therapy.

Being tested
Lung ultrasound

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lung ultrasoundDevice

    Also called Lung ultrasound score

    Lung ultrasonography ; lung ultrasonography will be applied in 4 quadrants according to the LUS protocol and LUS score will be created.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. LUS

    Lung ultrasound score (LUS) Lung ultrasonography; Lung ultrasound score will be created by performing ultrasonography in 4 quadrants according to the previously defined protocol.

    0 points indicated the presence of only A lines, less than 2 B lines

    1. point indicated 1-2 B lines
    2. points indicated the presence of more than 3 well-spaced B lines;
    3. points indicated the presence of combined B lines

    Measured: peroperative

Secondary outcomes (9)
  1. PVI

    Pulse variable index (PVI) will be measured by finger pulse oximetry with the MASİMO device.

    Measured: peroperative

  2. CVP

    Central venous pressure(CVP)

    Pressure values measured by a central venous catheter applied by jugular or subclavian route

    Measured: peroperative

  3. postoperative pulmonary complication

    hypoxia (partial oxygen pressure below 95 on pulse oximetry and 10% decrease from the initial value) atelectasis

    Measured: postoperative 6th hour

  4. biochemical data 1

    glomerular filtration rate (GFR) values normal results range from 90 to 120 mL/min/1.73 m2.

    Measured: postoperative 6th hour

  5. biochemical data 2

    Blood urea nitrogen value mg/dl

    Measured: postoperative 6th hour

  6. biochemical data 3

    Blood creatinine value mmol/dl

    Measured: postoperative 6th hour

  7. Mechanical ventilation data 1

    End-Tidal Carbon Dioxide Pressure mm/hg The partial pressure of CO2 detected at the end of exhalation is between 35 and 45 mm Hg or 4.0 to 5.7 kPa.

    Measured: peroperative

  8. Mechanical ventilation data 2

    Peak inspiratory pressure Values Peak inspiratory pressure is the highest pressure applied to the lungs during inhalation and should be kept below 35 cmH2O.It is automatically measured by respirators.

    Measured: peroperative

  9. Mechanical ventilation data 3

    Tidal Volume value Tidal volume is the volume of gas moving into and out of the lungs with each breath. Normal tidal volume is 6 to 8 mL/kg, regardless of age. It is automatically measured by respirators.

    Measured: peroperative

Questions about this trial

What is this clinical trial studying?

An observational study of Intraoperative Fluid Management, run by Korgün Ökmen.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 15 May 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Korgün Ökmen, PhD. (05057081021, korgunokmen@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

LUS (time frame: peroperative). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2025.
