What would cause Hgb to plummet? - page 2
I had a patient last week I can't stop thinking about. Med-surg floor, 40 yr old female, admitted with SOB and fevers one week s/p a Thymectomy to treat myasthenia gravis. After the surgery she had had some complications and... Read More
- 3Nov 17, '12 by nrsang97As an RRT nurse you can call me if you feel something is wrong. Dosen't matter what it is. I would say call with the slight cyanosis, no good RRT nurse would lose respect for you for that.
I encourage staff to call me for anything even if it outside the set paramaters we have to call RRT.

I think you did everything right. The doc probably should've investigated the cause of the 7.9 hgb and sob when you 1st called not wait until later in the day to do a recheck

Now, see, I like that example you used.
That's great visual.
Now think where the thymus gland is........
What complications can arise from a surgery that involves the chest? Did this patient have a chest incision? or was it done with a scope?
The patient had a bleed somewhere......that "feeling" in the right side of her chest.....and indicator that there is a BIG problem....in the lung which was already indicated with the large chest tube output from the other side of the chest.Last edit by Esme12 on Nov 18, '12
- 4Nov 18, '12 by Esme12, BSN, RN Senior ModeratorQuote from AlphaPigThis is to show you what to look for. How my thought process works.Bleeding easily causes a drop like that. Things that would stick out to me.....that this patient had a chest surgery....sternotomy. She has a history of having 850cc's of fluid removed from the opposite lung ( it would help you to find out what the fluid looked like). Thymectomy patients can have complications for several weeks post surgery.I had a patient last week I can't stop thinking about. Med-surg floor, 40 yr old female, admitted with SOB and fevers one week s/p a Thymectomy to treat myasthenia gravis. After the surgery she had had some complications and ended up having to have a left thoracentesis to remove 850cc fluid. Then, she went home for a few days before being readmitted with the SOB and fevers.
The day I had her (about 3 days after readmit), she looked a little pale and lethargic in the morning and was c/o right lung spasms when she breathed. Vitals normal, afebrile, O2 sat 97% on 3L NC. Pt slightly SOB, lungs diminished, but otherwise fine. However, Hgb was 7.9. Two days before it had been over 9. I called the MD and he ordered a CBC to be drawn later that afternoon to recheck it.
I gave the pt some IV dilaudid to help with the pain of the lung spasms, and besides being a little SOB, pt fine.
At 2:00, I draw the CBC and notice pt looking a little more pale with a slight bluish tinge to lips. Pt O2 sat 90% on 3L. Bump it to 4, call respiratory for a treatment and take the CBC to lab. 20 minutes later lab calls me to report Hgb of 5.9!
Called the MD with the results (who was just as surprised as I was) and he ordered some tests, 2 units blood, etc.
Go into room and find patient extremely SOB, anxious, bluish lips, pale, O2 sat 88% on the 4L. Bump the O2 to 6L and called a rapid response.
Pt ended up being transferred to the unit.
My question - where on earth was this lady bleeding?? No apparent GI bleed, pt's abdomen soft and flat, pt had just had a lung xray that morning that was unchanged from the previous days xray (moderate pleural effusions). I've never seen a Hgb drop that fast. I am relatively new and want to know if I am missing something obvious (if I am, please don't be mean to me, I want to learn)
Also, I don't know if this is related at all, but when I drew patient's lab, her blood was SO THICK and dark, it was like trying to get chocolate pudding out of her veins.
Now this patient is having specific "lung spasms" appears pale....I better keep an eye on her. I draw the labs at 2PM and I am alarmed that this patient is looking blue with circumoral pallor....and her sat is poor.....I bump her O2 to 6lpm and call resp to place patient on 100% O2.....I beg lab for an extra extra double fast H/H and have resp do abg's (especially if their machine gives a hGb) and I make sure lab has the blood READY ASAP! I probably would have called the RR now because this patient is actively deteriorating........
You did a good job....I personally would be a little more aggressive with the O2 and the "lung spasms would alarm me......well done!
- 6Nov 18, '12 by psu_213, BSN, RNQuote from Bec7074It is true that low hgb does not cause low sats, however low hgb can mean tissue hypoxia even in the setting of "normal" sats. If hgb is low that means there is less oxygen carrying capacity in the blood. So even if 100% of the hemoglobin is carrying oxygen (hence sats of 100%), there is still less oxygen being delivered to the tissues if the hgb significantly decreased. To use the truck example, if you normally have 20 trucks delivering the load, but now you only have 5 trucks, less is going to be delivered. Saturation is only part of the picture for tissue oxygenation; yet, as nurses, we are taught be obsessed with that number.First of all, low sats are not related to low hgb. This is a big misconception in nursing. I had a doc explain it to me once (cuz I too used to get confused). Low hgb is having less trucks on the highway but they can still carry the same load. Sats (% of oxy on hgb) is the load.Last edit by psu_213 on Nov 18, '12
