Talk:Intraoperative blood salvage

From Noblood

I have placed an image that was submitted, I believe by David Ampleford. I suggest if we use this image, that we 'number' elements referred to in the step-by-step guide. Laurence also offered to prepare a 'Mind-Map' version as well. Any comments are welcome regarding preferences for either approach. In either case, I need some lead time to make final preparation in order to have it ready for the November 1, distribution of the NoBlood Bulletin. LarryEitel 19:11, 19 October 2006 (CDT)

I am working on this but I am not convinced that the mind map will work. I'm working on it. Laurence Wilson 16:04, 21 October 2006 (CDT)

ToDo

I have pasted some material that seemed relavent from Wikipedia here. There are references also made at the end of the paragraphs. The idea is to adapt/cut/slash/reword/etc any of this material. Thank you! LarryEitel 16:44, 21 October 2006 (CDT)

Cell salvage graphic

I don't think the picture is correct, in the light of my editing of Step 1. The anticoagulant is mixed IMMEDIATELY with aspirated blood. otherwise it would coagulate in the tube before it got to the reservoir. I'm still working on my alternative version - accomodating Larry's comments on backgroundsetc. --Laurence Wilson 11:41, 25 October 2006 (CDT)

I am more familiar with the Fresenius CATS than the haemonetics cell saver, so I don't know how the Haemonetics m/c works. As I understand it, though, you certainly don't squirt anticoagulant onto a wound - and the mix with the aspirated blood has to take place soon after aspiration or it clogs the tube.--Laurence Wilson 16:37, 25 October 2006 (CDT)

Cell Salvage m/c pic

Might be good to identify the machine as a Fresenius, with apologies to other manufacturers --Laurence Wilson 11:43, 25 October 2006 (CDT)

Laurence, do you have a URL from where you found this image? We can also link to that product page as well. I don't think they would mind!! :) LarryEitel 12:05, 25 October 2006 (CDT)

Do you or anyone else have a list of companies that manufacture these machines? LarryEitel 12:05, 25 October 2006 (CDT)

Link: http://www.freseniushc.com/product/additional_products.html

List: Haemonetics, Medtronic, Fresenius Haemocare, Sorin --Laurence Wilson 12:31, 25 October 2006 (CDT)

Laurence, we're using the Haemonetics image at this point. Will contact them pursue permissions. LarryEitel 17:46, 29 October 2006 (CST)

Wikipedia exerpt

I tend to think that the piece from Wikipedia (which I have done a little work on) needs to be the basis of a separate article headed "Other Blood Salvaging Procedures", which would include a discussion of ANH and postoperative blood salvaging devices like the Donor and ConstaVac Systems.

At the very least I think this piece needs to be at the very end of the article so that it can be more easily distinguished from the discussion of cell salvage, which is what this article is mostly about.--DavidAmpleford

Looks like things were nicely cleaned up. LarryEitel 20:14, 26 October 2006 (CDT)

looking at the spleen as a resevoir similar to salvage resevoir

I was just wondering as I dont have much experience with the cell salvage , but it was to do with something i studied in medical college about the spleen being a natural blood reservoir in the body. Below I have placed a link to this function of the spleen which can help people to understand its possible similarity to the reservoir in the cell salvage and thus not think that the circuit is broken http://www.bartleby.com/65/sp/spleen.html The Columbia Encyclopedia, Sixth Edition. 2001-05.

spleen soft, purplish-red organ that lies under the diaphragm on the left side of the abdominal cavity. The spleen acts as a filter against foreign organisms that infect the bloodstream, and also filters out old red blood cells from the bloodstream and decomposes them. These functions are performed by phagocytic cells that are capable of engulfing and destroying bacteria, parasites, and debris. Ordinarily, the spleen manufactures red blood cells only toward the end of fetal life, and after birth that function is taken over by the bone marrow. However, in cases of bone marrow breakdown, the spleen reverts to its fetal function. The spleen also acts as a blood reservoir; during stress or at other times when additional blood is needed, the spleen contracts, forcing stored blood into circulation (see circulatory system). It is sometimes necessary to remove the spleen entirely, particularly in trauma cases, although recent studies have shown the spleen to be far more important than initially suspected in the fight against infection.

Don't know who submitted this item. Be sure to add 4 ~'s "~~~~" at the end of any comments.

I am thinking that the article on cell salvage should be one of several articles under the overarching title: "Medical Procedures Involving the Use of the Patient's Own Blood" to reflect the wording on the Health Care Directive card. There could be an Index as follows:

Medical Procedures Involving the Use of the Patient’s Own Blood

In medicine and surgery, there are a number of procedures (other than diagnostic testing) that make use of the patient’s own blood in one way or another. These can be grouped as shown below. Click on any procedure for a detailed discussion of what is involved.

1. Medical

Phlebotomy (for the treatment of hemochromatosis or erythrocytosis)
Hemodialysis (in the treatment of severe kidney disease)

2. Surgical

Preoperative autologous blood donation (PAD; PABD
Acute Normovolemic Hemodilution (ANH)
Intraoperative Cell Salvage
Intraoperative Blood Sequestration
- (Intraoperative Platelet Pheresis; Intraoperative Plasma Pheresis)
Intra-/Postoperative Whole Blood Direct Transfusion
- Cardiopulmonary Bypass Pump (“heart-lung machine”)
Intra-/Postoperative Whole Blood Recovery (Hemobag)
Postoperative Whole Blood Recovery (Donor System, Solcotrans, ConstaVac CBCII)
Intraoperative Blood Patch
Intraoperative Platelet Gel
Intraoperative Radionucleatide Tagging

Each of these bulleted items would then be a link to an article discussing these procedures in-depth. This would particularly benefit Witnesses, as they should be more easily able to perceive how these procedures relate to the choices they are being called upon to make.--DavidAmpleford

Excellent idea. I am particularly interested in determining the most accurate industry recognized terms that describe these treatments. Where is the best place to compare options? LarryEitel 23:28, 26 October 2006 (CDT)

Why?

In reference to the section Step_7:_Re-infusion "There is, however, a limit of 6 hours during which re-infusion can take place." Why is there a limit of 6 hours? Thanks! :) LarryEitel 13:51, 23 November 2006 (CST)

Revisions re-ultrafiltration

I made these revisions and want to disclose that I am a webmaster for many transfusion-related websites (list below), including Global Blood Resources, the maker of the Hemobag. My background is as a medical laboratory scientist & transfusion science educator.

Also, how does one get to upload a graphic? Thanks.
