Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
We administer intravenously infused over 30 minutes Hypertonic Saline with a concentration of 7.5% in a dose of 4 cc x kg of predicted body weight when the patients arrive to the ICU after a replacement valve surgery or a coronary artery bypass graft surgery that underwent extracorporeal circulation.
Intervention code [1] 291239 0
Treatment: Drugs
Comparator / control treatment
We administer intravenously infused over 30 minutes Normal Saline with a concentration of 0.9% in a dose of 4 cc x kg of predicted body weight when the patients arrive to the ICU after a replacement valve surgery or a coronary artery bypass graft surgery that underwent extracorporeal circulation.
Control group
Active

Outcomes
Primary outcome [1] 294357 0
The blood lactate sample was obtained from central venous catheter immediately after the admission of the patient in the ICU and then again after 6 hours, 12 hours and 24 hours.

Lactate is measured in the laboratory by chemical oxidation method.
Timepoint [1] 294357 0
Assessed on admission of the patient in the ICU and then again after 6 hours, 12 hours and 24 hours.
Secondary outcome [1] 313095 0
The cardiac index was measured by the thermodilution principle with a pulmonary artery catheter after the admission of the patient in the ICU and then again at 30 minutes, 4 hours, 6 hours, 12 hours and 24 hours.
Timepoint [1] 313095 0
Assessed on admission of the patient in the ICU and then again at 30 minutes, 4 hours, 6 hours, 12 hours and 24 hours.
Secondary outcome [2] 313096 0
The sample of mixed venous oxygen saturation was obtained with a pulmonary artery catheter after the admission of the patient in the ICU and then again at 30 minutes, 4 hours, 6 hours, 12 hours and 24 hours.

I - Stat system was used for measuring the mixed venous oxygen saturation.

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)
We used numbered containers without label of crystalloid solution to be used in both groups of the trial, since the 7.5% hypertonic saline solution and the normal saline solution are alike, neither the patient, medical staff or the investigators were aware of what was the solution used during the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomization using a random number generator (Ralloc Stata Co. 8,2)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes

Summary
Brief summary
This is a randomized double blind controlled trial that compares 7.5% hypertonic saline solution versus normal saline solution, in the resuscitation of the patients that underwent extracorporeal circulation surgery once they arrive in the ICU. The primary endpoint was to assess the lactate clearance within each arm of the study.
