The Correlational Study of PPV in Various VT in Mechanically Ventilated Patients

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01950949
Recruitment Status : Completed
First Posted : September 26, 2013
Last Update Posted : September 18, 2015

Yi Liu, Chinese PLA General Hospital

Brief 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. 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.

Condition or disease Intervention/treatment Phase
Respiration, Artificial Other: 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 Not Applicable
