Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Enteral ivabradine 5mg twice daily in addition to standard care.
Study treatment will be given for a total of 120 hours (5 days) or until the patient is discharged from ICU (whichever occurs first). In the event of bradycardia with a HR of <50 or in the presence of symptomatic bradycardia or in the event of AF or any visual disturbance, Ivabra-dine will be discontinued. These data will be included in the final manuscript of the study.
Intervention code [1] 312416 0
Treatment: Drugs
Comparator / control treatment
Standard care will be as per surviving sepsis campaign which include initial resuscitation without fluids, screening for sepsis, diagnostic tools, adequate antimicrobial treatment, source control, hemodynamic support with fluids, vasopressors, inotropic therapy ± corticosteroids and other supportive therapy or as per physician discretion.
Control group
Active

Outcomes
Primary outcome [1] 307434 0
Proportion of participants with a change in heart rate of less than 20 beats per minute compared to the heart rate before the start of Ivabradine. This outcome will be assessed utilising ongoing cardiac monitoring.
Timepoint [1] 307434 0
4 hours post administration of first dose of Ivabradine
Secondary outcome [1] 351889 0
Cardiac output as assessed by minimally invasive cardiac output monitoring device such as Vigilo or Flotrac.
Timepoint [1] 351889 0
every hour post administration of every dose of Ivabradine for total of 6 hours
Secondary outcome [2] 352439 0
blood pressure monitoring.All patients will have automated sphygmomanometer.
Timepoint [2] 352439 0
every hour post administration of every dose of Ivabradine for total of 6 hours

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
sequentially numbered sealed envelopes
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be by means of sequentially numbered sealed envelopes utilising permuted blocks of variable size. Each envelope will contain a study arm allocation.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
This is a pilot randomised controlled trial comparing the use of ivabradine plus standard care compared to standard care alone in the management of septic shock without multi-organ failure.
Phase
Phase 3
Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
Comparisons will be made using t-test and ANOVA for repeated-measures or Wilcoxon rank-signed test and Kruskall-Wallis according to the underly-ing distribution for continuous data and Chi-square for categorical data. Logistic regression analysis will also be performed to adjust for baseline im-balances. Analysis will be on an intention-to-treat basis.
