Trial summary

The investigators aimed to research the incidence of hyperlactatemia in craniotomy cases, the relationship of lactate elevation with tumor type and other factors that may be related, and whether the general anesthesia method applied (inhalation anesthesia or total ıntravenous anesthesia) affects lactate level.

About this study

The investigators aimed to research the incidence of hyperlactatemia in craniotomy cases, the relationship of lactate elevation with tumor type and other factors that may be related, and whether the general anesthesia method applied (inhalation anesthesia or total ıntravenous anesthesia) affects lactate level.

Read the detailed description

Lactate level is one of the easy-to-measure parameters that are frequently used in anesthesia and intensive care clinical practice, especially to evaluate the severity of disease and the response to treatment. In patients with high lactate levels, the first considerations are hypoperfusion and sepsis. However, many causes such as trauma, seizures, ischemia, diabetic ketoacidosis, thiamine deficiency, malignancies, liver dysfunction, genetic disorders, toxins, drugs, etc. can be associated with increased lactate. Many tissues in the body can produce lactate. 25% of production is from muscle, 25% skin, 20% brain, 20% RBC and 10% bowel cells. Some malignancies, especially hematological cancers, have also been associated with increased lactate. In recent years, it has been reported that serum lactate levels are associated with the degree of glial tumor malignancy, and that lactate can even be used as a non-invasive malignancy biomarker in brain tumors. In a recent study, it was reported that the type of 'glioblastoma multiforme' among patients who underwent craniotomy with the diagnosis of intracranial brain tumor was an independent influencer factor for preoperative and postoperative hyperlactatemia. Anesthesia is one of the factors that can affect lactate levels due to its effect on systemic perfusion and the hepatic effects of anesthetic drugs. It looks like that there is no study in the literature on the effect of anesthesia technique on hyperlactatemia in patients who underwent craniotomy. Therefore the investigators aimed to research the incidence of hyperlactatemia in craniotomy cases, the relationship of lactate elevation with tumor type and other factors that may be related, and whether the general anesthesia method applied (inhalation anesthesia or total ıntravenous anesthesia) affects lactate level.

What is being measured

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

  1. lactate level

    basal lactate level via arterial blood gas at the beginning of surgery

    Measured: 0.hour

  2. lactate level

    lactate level via arterial blood gas at one hour after the beginning of surgery

    Measured: 1.hour

  3. lactate level

    lactate level via arterial blood gas at three hour after the beginning of surgery

    Measured: 3.hour

  4. lactate level

    lactate level via arterial blood gas at the end of the surgery

    Measured: after extubation at the end of surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Intracranial Neoplasm and Hyperlactatemia, run by Ankara Diskapi Training and Research Hospital at 1 site in Turkey (Türkiye).

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 2 inclusion and 2 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: finished, as of the sponsor's last update on 16 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

lactate level (time frame: 0.hour). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05145049, which also lists 5 linked publications.

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 16 May 2024.
