Possible causes of low H&H?
- 0Oct 31, '08 by miniangel729last 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)
4500 – 11,000/µl
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?
(first semester nursing student and feeling very lost.. =/)

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.

- 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)
