How low Hb warrant transfusion within symptomatic/asymptomatic people with/without comorbidities?

How low do we tolerate haemoglobin level in persons beside anaemia before we want to start transfusing? Persons with symptoms vs without symptoms; those with comorbidities vs otherwise previously healthy.
Answers:
Really depends on the clinician as well as the course of the anemia. Someone next to longstanding anemia who have been through the workup, has no identifiable or life-threatening grounds, and is assymptomatic, you might only transfuse prn when the dip down into the 7-8 range. At the other end of the spectrum if you've get a patient in the hospital say for something else and adjectives of a sudden they drop their Hb more than what's attributable to dilutional effects of IV fluids, then you have a much higher cutoff for giving blood regardless symptoms. Also enjoy to weigh the benefits of transfusion against the risks and practical aspects involved. Sorry I can't be more specific, but it really is case-by-case.
