Intervention/exposure

Study type

Interventional

Description of intervention(s) / exposure

The intervention group will have 72 hours of monitoring following randomisation with an EV1000/VolumeView monitoring device. An EV1000/VolumeView system is a haemodynamic monitoring device which utlises transpulmonary thermodilution method to provide calibrated haemodynamic parameters to guide fluid resuscitation. To provide transpulmonary thermodilution, an internal jugular or subclavian central line and a femoral arterial line must be inserted to the study participant. ICU clinicians will be responsible for the placement of an internal jugular or subclavian central line and a femoral arterial line to fit the EV1000/VolumeView device. An EV1000/VolumeView provides constant haemodynamic parameters which require calibration by transpulmonary thermodilution every 4 hours. Nursing staff were responsible for calibration of the devices every 4 hours during the intervention period. Once the EV1000/VolumeView was established, there was no further active interventions for the interventional group or the control group.

Treatment: Devices

Comparator / control treatment

In the control group, the treating ICU team could use any method of assessing fluid status/responsiveness commonly utilized in our ICU. This includes clinical examination, trends in blood pressure/lactate/urine output and transthoracic echocardiogram.

Active

Outcomes

Primary outcome [1]

Primary outcome of the study was total intravenous fluid use at 72 hours post randomisation. Intravenous fluid use is recorded on both fluid infusion charts and a total daily fluid balance chart is kept on our online medical records system. Cross checking the infusion charts and fluid balance chart allows assessment of total IV fluid use.

Timepoint [1]

72 hours post-enrolment into the study

Secondary outcome [1]

A secondary outcome was assessment of rationale for initiating fluid boluses. A study specific questionnaire was at patient's nursing station and was to be filled in at the time of each fluid bolus. The most senior clinician responsible for initiating a fluid bolus was asked to record the volume of bolus, type of fluid used, which parameters (eg. Heart rate, blood pressure, rising lactate, EV1000/VolumeView output) they used to decide a fluid bolus was necessary and which parameters they assessed following the fluid bolus to determine if the fluid bolus acheived their desired result.

Timepoint [1]

The questionnaire was to be completed any time a fluid bolus was given from enrollment to the intervention endpoint at 72 hours. If multiple boluses given, multiple questionnaires were completed for each study participant.

Secondary outcome [2]

Feasibility of trial; assessed by whether the sample size target is achieved and on number of patient fluid bolus questionnaires completed by the treating clinician

Timepoint [2]

To be evaluated at end of trial

Eligibility

Key inclusion criteria

adult patients (18 years or older) admitted with shock defined as ongoing hypotension, despite fluid resuscitation, requiring vasopressors to maintain mean arterial blood pressure (MAP) greater than or equal to 65 mm Hg +/- and a serum lactate greater than or equal to 2 mmol/L.

Minimum age

18 Years

Maximum age

No limit

Sex

Both males and females

Can healthy volunteers participate?

Key exclusion criteria

patients in hypovolemic/haemorrhagic shock or atrial fibrillation (AF), pre-existing need for dialysis, pregnancy and patients who were unlikely to remain in the ICU for at least 72 hours. Additionally, patients were excluded if advanced haemodynamic monitoring was consider essential by the treating clinician.

Allocation to intervention

Randomised controlled trial

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)

allocation involved contacting the holder of the allocation schedule who was "off-site" or at central administration site.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Block randomisation was performed via an independent statistician with block size of 4 and 1:1 allocation

Masking / blinding

Statistical methods / analysis

Sample size estimation using data from Pittard (2017) with an effect size of 300mls and standard deviation of 2000mls, determined that 697 patients would be required for a full study. Given this was a pilot trial to determine feasibility, we aimed to recruit at least 10% of this calculated number, as per pilot sample size guidelines established by Cocks and Torgerson (2013).

Summary

Brief summary

There is minimal evidence that the use of cardiac output monitor devices leads to an overall change in IV fluid use. We sought to investigate the feasibility of performing a randomised controlled study using calibrated cardiac output monitoring devices in shocked ICU patients and whether the use of these devices led to a difference in total volume of IV fluid administered.
