About this trial

This study aims to assess the safety and efficacy of GDHT using the non-invasive Starling™ SV System in elective neurosurgery. The tested group of patients (n=70) will be compared with a control group (n=70), where hemodynamic management will be guided by standard vital signs monitoring.

Trial outcomes

Primary outcomes

1

Number of participants with acute kidney Injury

Defined according to Kidney Disease Improving Global Outcomes (KDIGO) guidelines: Stage 1: serum creatinine 1.5-1.9 times baseline value within 7 days or ≥27 µmol l-1 (0.3 mg dl-1) increase within 48 h; urine output ≤0.5 ml kg-1 h-1 for 6-12 h Stage 2: serum creatinine 2.0-2.9 times baseline value within 7 days; urine output ≤0.5 ml kg-1 h-1 for 12 h Stage 3: serum creatinine 3.0 times baseline within 7 days or increase in serum creatinine to ≥354 µmol l-1 (≥4.0 mg.dl1 with an acute rise of \> 44 mmol l-1 (0.5 mg/dl-1) or initiation of renal replacement therapy or in patients \< 18 years, decrease in eGFR (estimated Glomerular Filtration Rate) to \< 35 ml min-1 per 1.73m2; urine output ≤0.3 ml kg1 h-1 for 24 h or anuria for 12 h. AESI will be analysed descriptively and compared between study groups.

Number of participants with acute Respiratory Distress Syndrome (ARDS)

The Berlin definition of Respiratory Distress Syndrome: Timing: Within one week of a known clinical insult or new or worsening respiratory symptoms and Chest imaging: Bilateral opacities not fully explained by effusions, lobar/lung collapse or nobles and Origin of oedema: Respiratory failure not fully explained by cardiac failure or fluid overload. Need objective assessment (e.g. echocardiography) to exclude hydrostatic oedema if no risk factor is presented and Oxygenation disorder: mild: PaO2 (partial pressure of oxygen in arterial blood):FIO2 (Fraction of Inspired Oxygen) between 26.7 and 40.0 kPa (kilopascal) (200-300mmHg) with PEEP (Positive End-Expiratory Pressure) or CPAP (Continuous Positive Airway Pressure) ≥5 cmH2O (centimeters of water). Moderate: PaO2:FIO2 between 13.3 and 26.6 kPa (100- 200 mmHg) with PEEP ≥5 cmH2O. Severe: PaO2:FIO2 ≤13.3 kPa (100mmHg) with PEEP ≥5 cmH2O. AESI will be analysed descriptively and compared between study groups.

Time frame
28 days
3

Number of participants with arrhythmia

Defined as electrocardiograph (ECG) evidence of cardiac rhythm disturbance. AESI will be analysed descriptively and compared between study groups.

Time frame
28 days
4

Number of participants with cardiac arrest

Cessation of cardiac mechanical activity, as confirmed by the absence of signs of circulation. AESI will be analysed descriptively and compared between study groups.

Time frame
28 days

Secondary outcomes

1

Duration of surgery

Duration of surgery (min) - will be analysed descriptively and compared between study arms

Time frame
During the surgery (hours)
2

Length of hospital stay

LOS (Length of stay, day of admission - day of discharge will be counted as 1 day) - will be calculated as a number of days between admission and discharge, analysed descriptively and compared between study groups.

Time frame
Days (up to 28)
3

ICU length of stay

ICU LOS (day of admission - day of discharge will be counted as 1 day) - will be calculated as a number of days between admission to the ICU and discharge from the ICU, analysed descriptively and compared between study groups.

Time frame
Days (up to 28)
4

28-day mortality

28-day mortality (number of patients who are not alive 28 days after randomization) will be evaluated as a number and percentage of patients who are not alive 28 days after randomization and compared between study arms.

Time frame
28 days after randomization
