Outcome Measures

Primary Outcomes (1)

  • TWA hypotension (measured with FlotracIQ)

    Time weighted average spent in hypotension, defined as MAP \<65mmHg for ≥1min

    intraoperative, starting 15 minutes after induction

Secondary Outcomes (9)

  • Incidence of hypotension (measured with FlotracIQ)

    intraoperative, starting 15 minutes after induction

  • Time spent in hypotension (measured with FlotracIQ)

    intraoperative, starting 15 minutes after induction

  • TWA hypertension (measured with FlotracIQ)

    intraoperative, starting 15 minutes after induction

  • Percentage of time in hypertension (measured with FlotracIQ)

    intraoperative, starting 15 minutes after induction

  • Incidence of hypertension (measured with FlotracIQ)

    intraoperative, starting 15 minutes after induction

  • +4 more secondary outcomes

Study Arms (2)

Conventional arm

NO INTERVENTION

Institutional Standard of Care with intention to keep MAP\> 65 mmHg. The FlotracIQ will be connected, but fully covered.

Treatment arm

ACTIVE COMPARATOR

FlotracIQ with HPI algorithm.

Device: FlotracIQ with HPI algorithm

Interventions

FlotracIQ with hypotension probability indicator (HPI) algorithm connected to arterial line. The treating anesthetist is provided with guidance by means of a flowchart suggesting when to treat and what. Timing of treatment and choice of treatment is then left to the discretion of the attending physician.

Treatment arm

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged 18 years or older
  • Planned for elective non-cardiac non-day surgery with an expected duration of more than 2 hours
  • Planned to receive general anaesthesia
  • Planned to receive an arterial line during surgery
  • Aim for MAP of 65 mmHg during surgery
  • Being able to give written informed consent prior to surgery

You may not qualify if:

  • Aim for MAP other than 65 mmHg at discretion treating physician
  • Significant hypotension before surgery defined as a MAP \<65
  • Right- or left sided cardiac failure (e.g. LVEF\<35%)
  • Known cardiac shunts (significant)
  • Known aortic stenosis (severe)
  • Severe cardiac arrhythmias including atrial fibrillation
  • Requiring dialysis
  • Liver surgery
  • Vascular surgery with clamping of the aorta
  • Perioperative Goal Directed Therapy (PGDT) protocol
