About this study

Official title: Current Status of Antihypertensive Drug Treatment in Non-cardiac Surgical Population

A cohort of hypertension patients undergoing elective non-cardiac surgery was constructed to investigate current status of antihypertensive drug treatment in non-cardiac surgical population.

Read the detailed description

Perioperative changes in blood pressure (BP) are associated with perioperative risks. However, there is little information regarding the current status of antihypertensive treatment in non-cardiac surgical population. A cohort of 351 hypertension patients aged between 18 to 85-year old undergoing elective non-cardiac surgery was constructed to investigate the application of antihypertensive drugs, systemic involvement, perioperative hemodynamics and internal environment to grasp the perioperative impact of different antihypertensive drugs, and to further provide a reference for the preoperative antihypertensive strategy of surgery patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT03953872
Study groupRoleWhat they receive
ARBGroup of angiotensin receptor blockers(ARB) monotherapy users. A subject was considered as an ARB user when the total prescription days of ARB monotherapy was at least 30.
combination of CCB and ARBGroup of calcium channel blockers(CCB) and angiotensin receptor blockers(ARB) combination users. A subject was considered as a CCB and ARB combination user when the total prescription days of CCB and ARB combination therapy was at least 30.
CCBGroup of calcium channel blockers(CCB) monotherapy users. A subject was considered as a CCB user when the total prescription days of CCB monotherapy was at least 30.
No treatmentGroup of nonusers of antihypertensives. A subject was considered as a nonuser never received regular antihypertensive treatment or total prescription days of antihypertensives was less than 30.

What is being measured

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

  1. perioperative blood press(BP)

    baseline BP before the operation, when entering and exiting post-anesthesia care unit(PACU)

    Measured: from the moment on arrival to the operating room until the moment leaving PACU, assessed up to 240 minutes.

Secondary outcomes (4)
  1. pH, base excess, and concentration of HCO3- in blood gases

    arterial blood gases detected by using the ABL800 (Radiometer Med Aps Ltd, Copenhagen, Denmark)

    Measured: 5 minutes after extubating in PACU

  2. the incidence of hypotension in PACU

    If there were more than two consecutive episodes of hypotension (which was defined as SBP less than 80% of baseline) a "rescue" intravenous bolus of 100 mg of phenylephrine was given.

    Measured: from the moment on arrival to PACU until 60 minutes after arriving or the moment leaving PACU, whichever came first, assessed up to 240 minutes.

  3. the incidence of hypertension in PACU

    the incidence of hypertension, which was defined as SBP greater than 120% of baseline

    Measured: from the moment on arrival to PACU until 60 minutes after arriving or the moment leaving PACU, whichever came first, assessed up to 240 minutes.

  4. hospitalization days

    The duration of this single episode of hospitalization

    Measured: from the date of admission until the date of discharge or date of death from any cause, whichever came first, assessed up to 100 days

Questions about this trial

What is this clinical trial studying?

An observational study of Perioperative Antihypertensive, run by RenJi 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 1 inclusion and 3 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 17 May 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.

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?

perioperative blood press(BP) (time frame: from the moment on arrival to the operating room until the moment leaving PACU, assessed up to 240 minutes.). 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 17 May 2019.
