Blood transfusion is very lengthy procedure and consumes a substantial time from patients and health care providers. On average, it may take most if not all the working day which leads to significant constrains on hospital bed utilization. It starts from pre-transfusion testing, clinical assessment, actual administration of blood and post-transfusion care. The main bulk of this procedure is usually related to administration of the blood which typically given over 3 hours (5ml/kg/hour), although there is no strong evidence to support that. Indeed, it has been accepted as standard of care to transfuse blood over short time as in emergency situations.
OBJECTIVE:
To determine the maximum tolerated blood transfusion rate that can be safely delivered in patient who required blood transfusion i.e. transfusing blood over short time.
METHOD:
This is a phase I, open label, nonrandomized, prospective and rate-finding study. A well-known dose escalation design called 3+3 design will be used to identify the maximum tolerated rate. To assure the safety of such procedure, blood transfusion rate will be escalated very slowly by 1 ml/kg/hour for each cohort until rate-limiting toxicities or maximum of 10ml/kg/hour.
Blood transfusion is the mainstay of care for patients with different types of chronic severe anemia like thalassemia major. However, it is associated with serious risks and complications. In addition, blood transfusion is a lengthy procedure starting from pre-transfusion testing, clinical assessment, actual administration of blood and post-transfusion care. The main bulk of this procedure is usually related to administration of the blood which typically given over 3 hours (5ml/kg/hour) or even longer in certain cases. On average, such procedure may take most if not all the working day which leads to significant constrains on hospital bed utilization. Also, it is a significant burden on the patient and his/her family to comply with chronic transfusion program. As consequences, this leads to repeated absences from work or school.
Although, it is the standard of care to infuse blood at rate of 5ml/kg/hour, there is no strong evidence to support that especially in pediatric population. Indeed, it has been accepted as standard of care to transfuse blood over short time in certain cases. For instance, in an emergency situation, it is allowable to infuse blood over less than one hour. Infusion of stem cells is allowed to be given over one hour as well without a major adverse event. In addition, blood donation is usually done over 30 - 60 minutes. As such, the goal for conducting this study is to find out if we can transfuse blood over the short time without causing any harm.
Transfusion associated circulatory overload (TACO) is one of the complications of blood transfusion and known to occur more in adult patients with specific risk factors. TACO is very rare phenomenon in pediatric patients with normal underlying cardiorespiratory functions. In Literature review in pediatrics there was only one case report and that patient had a significant other co-morbidities and risk factors.
In our study, there will be many safety measures taking in our consideration starting by very selective criteria to roll the patients in the study with clear inclusion and exclusion points. Blood transfusion rate determine during the study and will be escalated by 1ml/kg per each cohort only and before starting the blood transfusion vital signs will be taken then 15 minutes after blood transfusion running and by the end of the procedure so there will be 3 times documented vital signs and for more safety issue the patients will be attached to cardiopulmonary monitoring during the whole procedure. Our patients will have ECHO pre-and post-transfusion to detect right ventricle load. Patients will have Brain natriuretic peptide (BNP) level will be done before and after finishing of blood transfusion.
Then at the end, 24 hours post transfusion evaluation will be done for all patients in the study.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

The intervention for the arm (blood transfusion escalation rate) will be about giving blood transfusion with escalating rate as described in intervention part to Any condition that expected to receive more than one blood transfusion, like thalassemia major or intermedia, sickle cell anemia, aplastic anemia, malignant diseases.
Biological: Blood transfusion escalation rate
3+3 dose escalation (3 patients/cohort) each started on a fixed rate (standard is 5 ml/kg/ hr).1st cohort start at 6ml/kg/hr till complete prescribed volume. Rate escalation by 1ml/kg/each cohort until dose limiting toxicities (DLTs) or max of 10ml/kg/hr. If no DLTs new cohort enrolled at the next planned rate. If DLTs seen in 1 patient in the cohort, another 3 patients treated with the same dose level.1ry phase I end point is maximum-tolerated rate (MTR) of blood transfusion that can be infused safely ( max rate at which 1 or fewer of 3 patients experienced DLT) or dose of 10ml/kg/hr. DLT is transfusion related adverse event lead to stop of transfusion. MTR is highest dose at which no more than 1of 6 patients experienced a DLT.15 additional patients enrolled at MTR to confirm safety.
can we transfuse blood over shorter period?
primary out come is transfusion associated circulatory overload(TACO), The Frequency will be used in the study to measure the primary outcome (TACO).
