About this study

Official title: Brain Relaxation Facilitated by Mannitol in Craniotomy: Insight Into the Optimized Operation Window

Although mannitol is used for brain relaxation during neurosurgery and in the treatment of raised intracranial pressure; there is not a consensus on its safe, effective dose and the duration of its administration. This study aimed to compare the effects of the mannitol in different use times, on the brain relaxation, electrolyte, lactate levels of the blood, peroperative fluid balance and the volume of the urine in supratentorial mass resection surgeries.

What is being measured

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

  1. brain relaxation score

    difference in brain relaxation after drug administration

    The assessment was performed using a 4-point scale,

    1 denoting bulging or the condition that additional methods for brain relaxation are immediately and always required in order to continue the surgical procedure because of brain swelling;

    2, firm or the condition that additional methods for brain relaxation are occasionally required to continue the surgical procedure;

    3, adequate; 4, perfectly relaxed.

    In all patients, the degree of brain relaxation was assessed at the time of dural opening and satisfactory brain relaxation was defined as a brain relaxation score of 3 or 4.

    All the Secondary Outcome Measures below are observed the safety for intraoperative brain debulking during elective supratentorial craniotomy

    Measured: just before dural opening

Secondary outcomes (5)
  1. Blood sodium levels

    Measured: change in 30 minute intervals in the first 2 hour after study drug administration

  2. Blood potassium levels

    Measured: change in 30 minute intervals in the first 2 hour after study drug administration

  3. Blood chlorine levels

    Measured: change in 30 minute intervals in the first 2 hour after study drug administration

  4. Blood lactate levels

    Measured: change in 30 minute intervals in the first 2 hour after study drug administration

  5. Fluid balance during operation

    Measured: change in 30 minute intervals in the first 2 hour after study drug administration

Questions about this trial

What is this clinical trial studying?

A study testing Mannitol in people with Supratentorial Tumors, run by Huashan Hospital at 1 site in China.

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 5 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 20 Nov 2020. 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 China. 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?

brain relaxation score (time frame: just before dural opening). 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 20 Nov 2020.
