Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Patients were randomly allocated into three equal groups (30 patients each). Group I (control group): Patients scheduled for acute normo-volemic hemodilution (ANH) alone after induction of general anesthesia. Group II: Patients received oral ferrous iron sulfate 320 mg tablets twice daily for 2 weeks before surgery and scheduled for ANH after induction of general anesthesia. Group III : Patients received oral ferrous iron sulfate 320 mg tablets twice daily and recombinant human erythropoietin (rHuEPO) in a dose of 100 IU /kg subcutaneously twice a week for 2 weeks before surgery and scheduled for ANH after induction of general anesthesia.
The ANH was started just after tracheal intubation through the internal jugular vein. The volume to be withdrawn was calculated (maximum 3 unites), while maintaining the Hct level more than 28%. The first 1000 cc of blood withdrawn was replaced with equal volume of hydroxyl-ethyl starch 6%, then any additional blood was replaced with crystalloid solution in the ratio of 3:1.
The volume of blood that could be withdrawn during ANH from each patient was calculated using the following formula:
V = EBV × (Hi – Hf )/ Hav
V = Volume of blood that could be removed
EBV = Estimated blood volume Hi = initial hematocrite level Hf = the target hematocrite level following ANH
Hav = the average hematocrite level of Hi and Hf.
The number of blood units withdrawn by ANH was recorded.
The volume of blood loss was estimated by estimation of blood in the surgical sponges (5 = mildly, 10 =moderately, and 15 = severely soaked) and pads (50 = mildly, 100 = moderately, and 150 = severely soaked) and, observing the volume of blood in the suction apparatus and the surgical drains.
Blood transfusion was given if Hb level was < 8 g/dl and, if there was abnormal ECG, ischemic heart disease or obstructive lung disease and the Hb level was 8-10 g/dl. No transfusion was given if Hb level was more than 10 g/dl.
If the patient was in-need for blood transfusion, the blood removed by ANH was given first, starting with the last unit collected then, homologous blood. At the end of surgery all autologous blood was returned to the patient. The first 1000 cc of blood withdrawn by ANH were replaced with equal volume of 6% hydroxyethyl starch. Subsequent blood withdrawn was replaced with ringer’s solution at a ratio of 3 :1.
All patients were pre-medicated with 0.01 mg/kg midazolam intravenous before induction of anesthesia and monitored for ECG, oxygen saturation, capnography and non-invasive blood pressure. A urinary catheter was inserted for collection of urine output.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization between group II and III (treatment groups) was done using closed sealed envelops and computer generated random numbers two weeks before surgery. While, patients of the control group were selected randomly at the time of operation using closed sealed envelops and computer generated random numbers. A blinded nurse, who did not participate in data collection read the patients number.
