About this study
Official title: Can Vena Cava Ultrasound Guided Volume Repletion Prevent Spinal Induced Significant Hypotension in Elective Surgical Patients? A Randomized, Case Control, Prospective Trial.
Aim of this study is to determine whether Inferior Vena Cava analyzed by trans-thoracic echocardiography is an effective method to guide titrated fluid repletion in non critical patients, in order both to decrease post procedural significant hypotension rate and to avoid unnecessary fluid overload in patients undergoing spinal anesthesia for elective surgical procedures
Read the detailed description
The setting is standard spinal anesthesia and corresponds to our first arm of the study, used as the control sample and statistical reference. During the induction phase, the patient is fitted with non-invasive blood pressure monitoring, three-lead ECG, pulse-oximetry and peripheral intravenous device. Data and vital signs are recorded and an infusion of crystalloid (NaCl 0.9% or Ringer's acetate) is given during the procedure until the beginning of the operation. Total amount of fluid is also recorded before and after the spinal anesthesia.
In addition to the current clinical standard, for the second arm of the study, a trans-thoracic echocardiography is performed before spinal anesthesia, with the aim of assessing the patient's volume status; the exam is performed to assess size and collapsing of the Inferior Vena Cava during breathing cycle. According to different pre-established parameters, the patient is defined as fluid-responsive or unresponsive. If the patient is not responsive, investigators proceed to spinal anesthesia; otherwise they proceed to administration of crystalloid bolus (500 ml of NaCl 0.9% or Hartmann's solution). The patient may receive another bolus so as to reach a non-responsive pattern for echocardiographic evaluation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ultrasound-guided volemic repletionDevice
Also called IVCUS
After echocardiography analysis of Inferior Vena Cava, patient is repleted with a pre-established bolus of fluid (500 ml of crystalloid). After this repletion, patient is analyzed till the exam reach signal of non-responsiveness, previously defined as a reduction of Inferior Vena Cava diameter less than 36% from baseline level during normal breath

What is being measured
The primary outcome is the main question the study is designed to answer.
Rate of Arterial Hypotension
To compare rates of arterial hypotension (previously define by international standard) after spinal anesthesia in patients who have undergone volemic optimization according to Trans-thoracic Echocardiography with patients who have been treated according to the current standard on the intention to treat population.
Measured: 30 minute after spinal anesthesia
Secondary outcomes (3)
Total Amount of IV Fluid at the End of the Procedure
To assess if there is a difference between all treatments in the total quantity of fluids amount
Measured: 30 minutes after spinal anesthesia
Percentage of Participants Administered Vasoactive Drug
Total amount of vasoactive drug administered for each group; for "vasoactive drug" we intended the use both of atropine than vascular amine
Measured: 30 minutes after spinal anesthesia
Time of Procedures
Time employed to execute all procedure from the start of the study till 30 minutes after the end of the procedure
Measured: From time 0 to 30 minutes after spinal anesthesia

Aim of this study is to determine whether Inferior Vena Cava analyzed by trans-thoracic echocardiography is an effective method to guide titrated fluid repletion in non critical patients, in order both to decrease post procedural significant hypotension rate and to avoid unnecessary fluid overload in patients undergoing spinal anesthesia for elective surgical procedures
Detailed description
The setting is standard spinal anesthesia and corresponds to our first arm of the study, used as the control sample and statistical reference. During the induction phase, the patient is fitted with non-invasive blood pressure monitoring, three-lead ECG, pulse-oximetry and peripheral intravenous device. Data and vital signs are recorded and an infusion of crystalloid (NaCl 0.9% or Ringer's acetate) is given during the procedure until the beginning of the operation.

Questions about this trial
What is this clinical trial studying?
A study testing Ultrasound-guided volemic repletion in people with Fluid Overload and Anesthesia; Adverse Effect, Spinal and Epidural, run by Ente Ospedaliero Cantonale, Bellinzona at 1 site in Switzerland.
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 6 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 31 Aug 2017. 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 Switzerland. 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?
Yes. Results are posted in the registry (first posted 20 Apr 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Rate of Arterial Hypotension (time frame: 30 minute after spinal anesthesia). 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 NCT02271477, which also lists 17 linked publications.
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 31 Aug 2017.
