The Correlational Study of PPV in Various VT in Mechanically Ventilated Patients
A study testing 300 ml Hydroxyethyl Starch 130/0.4 and Sodium Chloride Injection infusing in 15 minutes if PPV under VT 8 ml/kg was larger than 13% in the initial investigation in people with Respiration, Artificial, run by Yi Liu.
Trial summary
Mesquida, J et al showed there was a significant linear correlation between pulse pressure variations under tidal volume 6 ml/kg and 8 ml/kg in patients after the resuscitation phase of severe sepsis and septic shock. No study revealed the actual relationship between various PPV under different VT. Read more about this study

About this study
Official title: The Correlational Study of Pulse Pressure Variation in Various Tidal Volume in Mechanically Ventilated Patients Under General Anaesthesia
Mesquida, J et al showed there was a significant linear correlation between pulse pressure variations under tidal volume 6 ml/kg and 8 ml/kg in patients after the resuscitation phase of severe sepsis and septic shock. No study revealed the actual relationship between various PPV under different VT. So we hypothesized that there were relationship between various PPV in different tidal volume settings. The objective of this study was to examine the relationship between various PPV.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Mesquida, J et al showed there was a significant linear correlation between pulse pressure variations under tidal volume 6 ml/kg and 8 ml/kg in patients after the resuscitation phase of severe sepsis and septic shock. No study revealed the actual relationship between various PPV under different VT. So we hypothesized that there were relationship between various PPV in different tidal volume settings. The objective of this study was to examine the relationship between various PPV.

Questions about this trial
What is this clinical trial studying?
A study testing 300 ml Hydroxyethyl Starch 130/0.4 and Sodium Chloride Injection infusing in 15 minutes if PPV under VT 8 ml/kg was larger than 13% in the initial investigation in people with Respiration, Artificial, run by Yi Liu.
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 1 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 18 Sep 2015. 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?
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?
invasive arterial blood pressure as a Measure of Safety (time frame: Day 1). 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 NCT01950949, which also lists 1 linked publication.
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 18 Sep 2015; AzTrials last refreshed its copy on 6 Nov 2026.
