| Study group | Role | What they receive |
|---|---|---|
| norepinephrine | Experimental | Blood pressure is generally maintained at value not less than 80% of baseline during intraoperative period. If the blood pressure is within normal range and SVV is less than 9, patient will be given a continuous infusion of crystalloid solution. However, when blood pressure drops and SVV is greater than 13, a bolus of 200mL colloid will then be quickly administered. If the blood pressure doesn't recover back to normal range within 5 minutes after bolus, norepinephrine will be given through the central venous catheter. If SVV is between 9 and 13, a bolus of crystalloid at 8mL/kg/h will be administered Receives: Drug: norepinephrine |

What is being measured
The primary outcome is the main question the study is designed to answer.
hemodynamics- (CO)cardiac output
(CO)cardiac output in Litres per minute. the indicator reflect the patients hemodynamic, which measured by the FloTrac/Vigileo 3.0
Measured: change from patient enters the operating room to end of operation, assessed up to the whole operation
Tissue perfusion and oxygenation-(DO2) Oxygen delivery;
Blood samples from the radial artery and internal jugular vein were taken at the same time in three time points respectively to measure arterial and venous blood gas, and Measured tissue oxygenation according to Fick equation:DO2(ml/min/m2)=CaO2×10×CI, Arterial oxygen content (CaO2)=Arterial hemoglobin concentration(Hba)×1.36×arterial oxygen saturation(SaO2) + 0.0031×arterial oxygen pressure (PaO2) ;
Measured: change from beginning of operation to end of operation, assessed up to the whole operation
Tissue perfusion and oxygenation-(VO2)Oxygen consumption;
Blood samples from the radial artery and internal jugular vein were taken at the same time in three time points respectively to measure arterial and venous blood gas, and Measured tissue oxygenation according to Fick equation:VO2(ml/min/m2)= (CaO2-CcvO2)×CI×10, Intravenous oxygen content (CcvO2)= Intravenous hemoglobin concentration (Hbv)×1.36×Venous oxygen saturation (ScvO2) + 0.0031×venous oxygen pressure (PcvO2);
Measured: change from beginning of operation to end of operation, assessed up to the whole operation

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing norepinephrine and Phenylephrine in people with Hypotension, run by The Second Affiliated Hospital of Dalian Medical University 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 4 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: status not confirmed, as of the sponsor's last update on 8 Oct 2019. 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact xiao z yang, MD,PHD (17709873399 ext. 0086, xiaozhaoy2012@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
hemodynamics- (CO)cardiac output (time frame: change from patient enters the operating room to end of operation, assessed up to the whole operation). The study lists 3 primary outcomes in all. 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 8 Oct 2019.
