How low can hemoglobin go before you need a transfusion?

How low can hemoglobin go before you need a transfusion?

It depends...: What's the cause? How quickly has the hemoglobin dropped/is there any ongoing bleeding? Is there evidence of inadequate tissue perfusion? What other acute & chronic medical problems does the patient have? In critically ill patients who aren't bleeding, a hemoglobin as low as 7 g/dl is generally well tolerated. Decision to transfuse should be based on desired physiologic effect, not on a number. ...Read more

How low must hemoglobin be to get transfusion?

Low: Due to the potential side-effects and risks of transfusion and the chronic blood shortage the us has, most would agree that transfusion should occur only if the hemoglobin is less than 8gm/dl (normal 12-16) or at any level if the patient is symptomatic or if there is significant active bleeding. ...Read more

How can you treat persistent low hemoglobin counts following chemotherapy, other than blood transfusion?

How can you treat persistent low hemoglobin counts following chemotherapy, other than blood transfusion?

Not many: Your heme-onc dr is an expert in this, and should have discussed (or tried) a gmcsf injection to stimulate your body's red blood cell production. But, many cancer pts do not respond to it--either due to the nature of the cancer or the treatment or both. If not amenable to induction of production, then will need transfusion every so many weeks. I see many pts who do this, and once used to it are ok. ...Read more

I am on Actermra for Scleritis and have 10 for my hemoglobin level, is that too low to do next infusion and when too low and need transfusion?

Hemoglobin level: Most centers will not transfuse a stable non bleeding patient with a hemoglobin over 7. Speak with your doctor if you are having symptoms due to anemia. I know Acterma can cause decreased platelets and WBC but I did not know it caused anemia too. Speak with your doctor. ...Read more

I had a blood transfusion due to low hemoglobin. My iron level was 6 and is now 9 after two units. I still feel weak and really tired after 3 days?

Of course you do: You are still seriously anemic. Be proactive. Insist on an explanation of how you got this sick and what wil be done to restore you to health. If you have a bleeding stomach ulcer, what will be done? If you have hemolysis, what is the cause? G6PD status? Were you malnourished? You deserve a full explanation. ...Read more

Very low hemoglobin after transfusion for postpartum hemorrhage?

What is the question: Hello fbruno6. If you are still bleeding, your hemoglobin may remain low. Continued transfusions, if needed, will bring up the hemoglobin. You may also have underlying iron deficiency and that also needs to be treated. I am not sure of what your question is, but hope that the above information is helpful to you. ...Read more

Is 9.4 Hemoglobin still low? (2 weeks ago needed 3 emergency blood transfusions due to major blood loss from Gastrointest. Hemorrhage w/melena).

Is 9.4 Hemoglobin still low? (2 weeks ago needed 3 emergency blood transfusions due to major blood loss from Gastrointest. Hemorrhage w/melena).

Not really.: 9.4 is low but it's not " Too"' low. More important is whether you are having symptoms of anemia (heart racing, low blood pressure, short of breath, etc). Your blood count should increase unless you are still bleeding internally. Did they find a source?? Follow with your GI Doc. You will need scopes if not already done If the returns go to ER ...Read more

Hemoglobin 13.7 low iron. Need to be concern? What's problem. Not bleeding. Anemic before w/ transfusons. Transfusions again. Iron level from the labs MCV or mvc. My hematologist was concerned. Ideas?

Hemoglobin 13.7 low iron. Need to be concern? What's problem. Not bleeding. Anemic before w/ transfusons. Transfusions again. Iron level from the labs MCV or mvc. My hematologist was concerned. Ideas?

Iron deficiency....: It sounds like you have iron-deficiency anemia. With a hemoglobin of 13.7, it is relatively mild at this time but still needs to be diagnosed. Have you had a colonoscopy? Microscopic blood loss from the GI tract can present like this. Colon polyps or even colon cancer can result in iron deficiency anemia. These conditions are very treatable, even curable, if caught early so see a GI doctor asap! ...Read more

At what hemoglobin level will I need a transfusion?

At what hemoglobin level will I need a transfusion?

No definite level: This is a complex question. We would need to know what is the patient's problem. If there is no immediate surgical issue, then transfusions are given if there are symptoms like chest pain. If there is blood loss during surgery, then indications are different. At our hospital, the medical staff has said there should be no transfusions unless the hemoglobin less than 8 gm/dl. ...Read more

Sir my child hemoglobin is less than 10, and his age is 20 days so, what you suggest about blood transfusion?

Sir my child hemoglobin is less than 10, and his age is 20 days so, what you suggest about blood transfusion?

No: This is in the normal range for this age. Questions to ponder are: is the child's skin yellow? Is the child feeding well and otherwise appear healthy? Some will have a minor form of blood group mismatch with their moms blood resulting in decrease of the hemoglobin levels for some weeks after birth. ...Read more

86 y/o female hemoglobin ia 61, creatinine is 3.6, is blood transfusion needed right away?

Is Haemoglobin 6.1g?: If you have chronic kidney disease you usually can tolerate anemia (low hb) better than people with no kidney dz. This is because kidney produces erythropoietin, needed for red cell prodction in bone marrow.

In your case hb of 6.1 is concerning and you need few things, get worked up for anem., consult a nephrologist, probably 1-2 units-packed redcells transfusion, iron + or -, erythropoi. Suppl. +/-. ...Read more

Is 8 weeks of iron infusions enough? Ater this time hemoglobin decreased to 7.6. As a result, I had a blood transfusion.

Is 8 weeks of iron infusions enough? Ater this time hemoglobin decreased to 7.6. As a result, I had a blood transfusion.

Something's wrong: If iron infusions over eight weeks didn't fix your anemia, it's either not due to iron deficiency or you still have serious blood loss. I also see that somebody is giving you vitamin B12 for whatever reason. Please forgive my frankness. If there is not a misunderstanding, please get with a hematologist. ...Read more

How long could it take for my hemoglobin level to return to its pre-surgical range if I receive a transfusion? If I didn't?

6-12 weeks: There are a number of variables here. First, how low was your hemoglobin when you started? Second, if you received a transfusion, what was your hemoglobin after? It takes about 90 days to cycle through your blood supply, so after 3 months, you should be back to your baseline. ...Read more

Is blood transfusion really needed right away for a 86 years old patient with creatinine level of 3.6 and hemoglobin of 61?

Blood transfusion?: If the patient is hypotensive and has a rapid heart rate, a blood transfusion is mandatory. A hemoglobin (h) of 6.1 is about 30% that of a normal h of. Unless the patient is in hospice care, the patient, or the patient's family, should be offered the option of a blood transfusion to elevate the h to a level > than 10 gm/dl. ...Read more

Extremely anemic (transfusion jan 27) hematocrit tested today was at 30%. Hemoglobin test not available. Will I need another transfusion?

Transfusion?: Anemia can be due to blood loss usually via the GI tract, an impaired bone marrow that cannot make red blood cells (rbc) or due to destruction of rbc's in the vessels. What did the doctors tell you your anemia was due to? At a hematocrit of 30%, you will not need a transfusion now. Speak to the doctors who transfused you for more information as they know your case best of all. Good luck. ...Read more

If I will be undergoing myomectomy surgery -fundal fibroids (3), in my 30's, what is normal hb (hemoglobin)? Do I need blood transfusion?

If I will be undergoing myomectomy surgery -fundal fibroids (3), in my 30's, what is normal hb (hemoglobin)? Do I need blood transfusion?

About 12-16 g/dL.: Normal hemoglobin for an adult female is between 12-16 g/dl (7.4-9.9 mmol/l). You might need blood, like 2 units for your surgery to replace any blood lost. If you are anemic, which might be the case in these circumstances, you might need more. At any rate, your doctor, to prepare you for surgery might talk to you about autologous transfusion, or donating blood to yourself. Best of luck. ...Read more
