Cell Salvage in operations for gynaecological malignany
(1 message)
By: Dr Smruta Shanbhag
Sub-specialty trainee
Gynaecological Oncology
James Cook University Hospital
Middlesbrough, UK - 24-10-2007 - 12:18
I am a sub-specialty trainee and my query is regarding use of cell salvage in gynaecological cancer operations.
1. During these operations, most of the blood loss is saoked up using mops and swabs rather than large volumes in the suction.
2. The area in which we operate can involve opening the cervix/ vagina/ bowel.
3. The malignancy usually is advanced enough to involve the abdominal contents - peritoneum, omentum and bowel.
A brief literature search for cell salvage in these operations has not revealed much, as most operations are for...
Benign tumor and ethical problems and intraopeative blood salvage and follow up
(1 message)

China - 11-06-2007 - 15:37
Dear sir,
I’m a doctor from Beijing. I’m very interested in intraoperative blood salvage(IBS). Currently, cancer surgery is considered as contraindication to IBS for the worry about dissemination of tumor cells. Some benign tumor such as meningioma and so on also can metastasis through blood circulation in rare condition. However, the first series of utility of IBS is used in resection for meningioma, and till now IBS is still routinely used in meningioma surgery in some countries. Is it an appropriate practice? Will it be approved internationally? If we want to determine the safety of ...

Cell saver use instead of typing and crosmmatching

I am in the midst of talking with some hospitals about using the cell saver in all surgeries where you have to type and crossmatch a patient. I have been told that on a national average the cost to type and crossmatch a patient is about $600.00. If we could do a standby procedure (resevoir & suction) rather than typing and crossmatching on every patient it would save the hospital and the patient money. Your feedback would be appreciated....

Allogeneic transfusions still present serious concerns. Pre-donated autologous blood offers greater protection from viruses and contaminants, but can adverserly affect a patient's health, recovery and outcome by allowing him or her to go into surgery anemic and hypovolemic. By freezing and storing your blood (up to ten years for RBCs) and having it delivered for a scheduled surgery, patients can go into an operation without anemia, a lower blood volume and with autologous units of fresh blood available during and after surgery. This procedure is enhanced further when patients are treated with...

We fully agree with Dr. Fergusson that we should not immediately abandon the use of aprotinin. He correctly summarizes the limitations and potential bias of the study by Mangano et al (1). The results of the Canadian BART trial will be extremely important and should be awaited before making definitive conclusions (2).

Particles in processed blood

I have found some debris and particles in the processed blood under SES. Most of them are bone chips. I know this problem is difficult to solve in neurosurgeries or orthopedic operations, because the cell-washing systems are not able to completely remove the particles whose densities are similar or higher than red blood cells. The filter within the reservoir can only prevent the particles larger than 30 μm (Cobe Brat 2) mixing with the blood. So I wonder whether the particles will harm the patient. Do you have any reports or documents associated with the problem of cell washing? I wonder ...
Erythropoietin and oral iron for myelodysplasia

Buenos Aires, Argentina - 01-12-2005 - 16:08
Patients with Myelodysplasia (specially RA with only one cytopenia as anemia)have good responses to high doses of EPO when their endogenous EPO is low, thus remaining free from transfusion. However, some experts argue that one should administer intravenous iron for better results although their ferritin levels are high. In my experience I use oral iron and get good results too (no transfusion dependent patients). Has anyone had the same experience?...
Can oral replace intravenous iron in patients with EPO?

Patients with myelodysplastic syndromes (mostly Refractory Anemia with one cytopenia) are given Erythropoietin to diminish transfusions. Although their Ferritin levels are always high it is advised to give them intravenous iron in order to increase erythropoiesis after exogenous erythropoietin is began. But little is known about the timing to begin with iron and about oral and dosage administration instead of intravenous. In my experience with the use of oral iron I have had good results but I would like to know the experiance of others with the use of oral iron in this setting....

Neurosurgery is a kind of surgery that haemostatic function should be maintained very well because minor hemorrhage often associates with devastating effects. A platelet count of higher than 100 x 109/L has been recommended for those with multiple trauma or central nervous system injury (Development Task Force of the College of American Pathologists, 1994; Horsey, 1997). Some experts also recommend that in such surgery the use of FFP can not strictly base on the guidelines - FFP ...

Erythropoietin in cancer patients

Erythropoiesis is iron-dependent. Most cancer patients are iron-deficient, so iron substitution is usually necessary in erythropoietin therapy. Many tumors are iron-dependent, in some of the patients this even is the reason for their anemia.

When to transfuse FFP?
(1 message)
By: Crista
Anesthesiology - 01-02-2004 - 06:25
Many guidelines have advocated that FFP (fresh frozen plasma) should be transfused after blood loss exceeding 100% total blood volume in the condition of massive hemorrhage. Before blood loss beyond 1 blood volume, packed red blood cells and colloid solutions can be used to maintain oxygen transition capacity and blood volume. However, I think that the total protein concentration may decrease significantly to an abnormal level before blood loss exceeding 100% total blood volume, and make the blood volume difficult to be maintained stably. Furthermore, the colloid solutions most often used in o...

Surgery of malignant tumors is considered a contradiction to intraoperative blood salvage (IBS). Can IBS be safely used in surgery of benign tumors such as meningioma?
