Trial summary

Lymphatic venous anastomosis could be applied on patients suffering from limb lymphedema after surgery or radiotherapy. The particular pathophysiology leads unconventional fluid treatment strategy and changes in urine output. Read more about this study

About this study

Official title: Perioperative Hemodynamic Optimization Using the "Edwards" EV1000 Clinical Platform NI in Lymphatic Venous Anastomosis

Lymphatic venous anastomosis could be applied on patients suffering from limb lymphedema after surgery or radiotherapy. The particular pathophysiology leads unconventional fluid treatment strategy and changes in urine output. Hemodynamic monitors shows the benefits in perianesthetic care in fluid maintenance and decrease postanesthetic complication.

Invasive hemodynamic monitors, such as arterial line and FlowTrac, have risks of hematoma, infection, nerve injury in puncture site. In this study, photoplethysmography is applied comparing with conventional mean arterial pressure for perianesthetic hemodynamic optimization in bispectral index (BIS)-guided target-controlled infusion sedation on lymphatic venous anastomosis.

Read the detailed description

After allocation, patients would be assigned to Standard group or ClearSight group. All patients will be sedative with BIS-guided Propofol/Alfentanil Target-Controlled Infusion. The BIS will be maintained between 40-70 with electromyography(EMG) < 30%. Ce(effect site concentration) of Propofol is adjusted according to BIS score. Ce of Alfentanil is adjusted between 15-75 ng/ml. Patients have spontaneous respiration during the procedure with O2 simple mask. If the oxygen saturation by pulse oximetry(SpO2) < 95%, prescribe chin lift first. Nasopharyngeal airways is given if chin lift can not improve the saturation. Crystalloid, usually Lactate Ringer, is infused with the rate 4ml/kg/hr. The goal of Standard group is to maintain mean arterial pressure(MAP) > 60%. If MAP < 60%, 3ml/kg crystalloid is challenged in 10 minutes. If MAP still less than 60% after the second fluid challenge, Ephedrine 4-8mg iv is prescribed. ClearSight group is to maintain stroke volume(SV). If SV decreases more than 10%, 3ml/kg crystalloid is challenged in 10 minutes. If MAP still less than 60% after the second fluid challenge, Ephedrine 4-8mg iv is prescribed.

What participants receive

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

  • Standard groupDevice

    Also called S group

    Use radial arterial line to monitor mean arterial pressure

  • ClearSightDevice

    Also called CS group

    Use Edwards EV1000 Clinical Platform NI with ClearSight finger sleeve to monitor SV(stroke volume)

What is being measured

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

  1. Maximal MAP fluctuation

    In standard group, MAP(mean arterial pressure measured from arterial line), maximum minus minimum

    Measured: after induction until recovery from anesthesia, assessed up to 24 hours

  2. Maximal change of SVV

    In ClearSight group, SVV(stroke volume variation measured from ClearSight), maximum minus minimum

    Measured: after induction until recovery from anesthesia, assessed up to 24 hours

Secondary outcomes (4)
  1. Urine output

    urine output ml/kg/h

    Measured: after induction until recovery from anesthesia, assessed up to 24 hours

  2. Creatinine

    Creatinine (serum)

    Measured: preanesthesia and 24 hours postanesthesia

  3. Acute kidney injury

    use AKIN/RIFLE criteria

    Measured: Loss of kidney function that develops within 7 days after surgery

  4. Total fluid volume (ml)

    In both groups, total crystalloid fluid volume used during anesthesia

    Measured: after induction until recovery from anesthesia, assessed up to 24 hours

Questions about this trial

What is this clinical trial studying?

A study testing Standard group and ClearSight in people with Hemodynamic Monitoring and Perioperative Care, run by Chang Gung Memorial Hospital.

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 2 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: status not confirmed, as of the sponsor's last update on 12 Jun 2018. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Min-Hsien Chiang, M.D. (+886-7-7317123 ext. 2788, b9005035@cgmh.org.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximal MAP fluctuation (time frame: after induction until recovery from anesthesia, assessed up to 24 hours). The study lists 2 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 12 Jun 2018; AzTrials last refreshed its copy on 6 Nov 2026.
