Abstract

A method for improving recovery after surgery or an invasive procedure is provided, including administering a hemoglobin preparation to a patient before surgery or an invasive procedure.

Claims

1. A method for treating a patient before surgery or an invasive medical procedure, comprising scheduling a patient for surgery or an invasive medical procedure, and administering a hemoglobin preparation to the patient before the surgery or the procedure, the surgery or procedure being scheduled after taking into account that the surgery or procedure should be performed more than about 12 hours after initiating the administration, wherein the hemoglobin preparation contains from about 10 milligrams stroma-free hemoglobin per kilogram body weight to about 1,000 milligrams stroma-free hemoglobin per kilogram body weight and the stroma-free- hemoglobin is selected from the group consisting of crosslinked hemoglobin, conjugated hemoglobin, encapsulated hemoglobin and polymerized hemoglobin.

2. The method of claim 1 wherein said invasive medical procedure is catheterization or intubation.

3. The method of claim 1 wherein said mammal is a human.

4. The method of claim 1 wherein said crosslinked hemoglobin is diaspirin-crosslinked hemoglobin.

5. The method of claim 1 wherein the hemoglobin preparation contains from about 25 milligrams stroma-free hemoglobin per kilogram body weight to about 1,000 milligrams stroma-free hemoglobin per kilogram body weight.

6. The method of claim 1 wherein the hemoglobin preparation contains from about 50 milligrams stroma-free hemoglobin per kilogram body weight to about 400 milligrams stroma-free hemoglobin per kilogram body weight.

7. The method of claim 1 wherein said administering is carried out in a time period in the range of from about 72 hours to about 12 hours prior to said surgery or said procedure.

8. The method of claim 1 wherein said administering is carried out in a time period in the range of from about 48 hours to about 18 hours prior to said surgery or said procedure.

9. The method of claim 1 wherein said administering is carried out in a time period in the range of from about 36 hours to about 24 hours prior to said surgery or said procedure.

10. The method of claim 1 wherein said hemoglobin preparation is in the form of a physiologically acceptable solution for parenteral administration.

11. The method of claim 10 wherein said physiologically acceptable solution contains from about 1 g/dl to about 20 g/dl hemoglobin.

21. The method of claim 1 wherein the hemoglobin preparation contains from about 50 milligrams stroma-free hemoglobin per kilogram body weight to about 1,000 milligrams stroma-free hemoglobin per kilogram body weight.

12. A method for treating a patient before surgery or an invasive medical procedure, comprising administering a hemoglobin preparation containing from about 50 milligrams stroma-free hemoglobin per kilogram body weight to about 400 milligrams stroma-free hemoglobin per kilogram body weight to a patient within a time period of between about 72 hours and about 12 hours before the surgery or the procedure, wherein the stroma-free hemoglobin is selected from the group consisting of crosslinked hemoglobin, conjugated hemoglobin, encapsulated hemoglobin, and polymerized hemoglobin.

13. The method of claim 12 wherein said administering is carried out in a time period in the range of from about 48 hours to about 18 hours prior to said surgery or said procedure.

14. The method of claim 12 wherein said administering is carried out in a time period in the range of from about 36 hours to about 24 hours prior to said surgery or said procedure.

15. A method for treating a patient before surgery or an invasive medical procedure, comprising administering a hemoglobin preparation containing from about 10 milligrams stroma-free hemoglobin per kilogram body weight to about 1,000 milligrams stroma-free hemoglobin per kilogram body weight to a patient within a time period of between about 72 hours and about 12 hours before the surgery or the procedure, wherein the patient has not received any other dose of a hemoglobin preparation greater than or equal to said concentration during said time period, and the stroma-free hemoglobin is selected from the group consisting of crosslinked hemoglobin, conjugated hemoglobin, encapsulated hemoglobin, and polymerized hemoglobin.

16. The method of claim 15 wherein said crosslinked hemoglobin is diaspirin-crosslinked hemoglobin.

17. The method of claim 15 wherein the hemoglobin preparation contains from about 25 milligrams stroma-free hemoglobin per kilogram body weight to about 1,000 milligrams stroma-free hemoglobin per kilogram body weight.

18. The method of claim 15 wherein the hemoglobin preparation contains from about 50 milligrams stroma-free hemoglobin per kilogram body weight to about 400 milligrams stroma-free hemoglobin per kilogram body weight.

19. The method of claim 15 wherein said administering is carried out in a time period in the range of from about 48 hours to about 18 hours prior to said surgery or said procedure.

20. The method of claim 15 wherein said administering is carried out in a time period in the range of from about 36 hours to about 24 hours prior to said surgery or said procedure.

22. The method of claim 15 wherein the hemoglobin preparation contains from about 50 milligrams stroma-free hemoglobin per kilogram body weight to about 1,000 milligrams stroma-free hemoglobin per kilogram body weight.
