Possible causes of low H&H?

  1. 0 last week i had a patient with wound infection from laparoscopic bilateral salpingo-oophorectomy on her llq (post-op 17 days). her lab value was..(patient have htn and diabetes)

    wbc
    4500 - 11,000/l
    11.8 (h)
    hgb

    12-17 g/dl
    10.5 (l)
    hct

    35-52%
    31.2 (l)
    platelets
    150,000-400,000 /l
    457 (h)

    we had to give rationale of each abnormal lab value,
    for the h&h i put " patient is on antibiotic, which could cause ↓in hemoglobin count. also, patient have sob, which could also ↓ h&h."
    my instructor made a big deal saying how come i didn't mention her h&h are low due to post-op. i didn't understand why.. (cuz its already post-op 17 days, it shouldn't be due to blood loss?)
    she also asked me how long does it take for body to replenish h&h.

    can anyone tell me where i can look up for causes for abnormal lab values? and why should h&h be low after post-op and how long does it take to get back to normal level?

    oh.. another thing, why does diabetic have slow wound healing?

    Well, I will give it a shot! The body needs a few days to reproduce RBC, and if there are not enough of those then the Hct and Hgb will both be low causing anemia. The patient may have had a bleed before the surgery which would have also decreased the number and there is always blood loss during surgery which would also cause those numbers to be low. 17 days post op does seem like a long time but that would probably be what I would have put on my labs as a possible cause.
    With diabetes, there can be impaired circulation and altered carbohydrate metabolism slowing the healing of wounds.

    Is this what you were asking? A lot of times I just google exactly what I am looking for to try to understand whatever it is I am looking up.

    http://www.biosbcc.net/doohan/sample...od%20cells.htm - blood cells (nice explanation of erythropoetin and rbc cycle)
    http://www.anemia.org/professionals/monograph/surgery/ -
    • one-third to one-half of surgical patients may be anemic preoperatively because of conditions for which they require surgery.
    • post operative anemia may occur in up to 90% of patients, probably due to a blunted erythropoietic response. (surgery induced erythropesis)
    why does diabetic have slow wound healing?
    • http://www.betterhealth.vic.gov.au/b...m?opendocument - wounds, causes of chronic wounds, the healing process - "factors that can slow the wound healing process include. . . medical conditions - such as diabetes, anaemia and some vascular diseases that restrict blood flow to the area, or any disorder that hinders the immune system."
    • http://diabetes.niddk.nih.gov/dm/pub.../chapter22.pdf - "macrovascular disease and microvascular dysfunction may result in compromised local circulation leading to delayed response to infection and impaired wound healing."

    low H and H can also be due to extra fluids, such as an IV...
