Method and apparatus for monitoring hemostasis in connection with artificial surface devices
A method and apparatus for monitoring hemostasis in a connection with a recipient of an artificial surface device provide a multi-phase monitoring protocol. In a first, pre- and intra-operative phase, hemostasis of the recipient is monitored relative to preventing clot formation to achieve artificial surface patency. In a second, post operative phase hemostasis of the recipient is monitored relative to bringing about clot formation to achieve vascular recovery. In a third, stabilizing intensive care phase hemostasis of the recipient is monitored relative to balancing hemostasis toward an anti-coagulation bias. In a fourth, maintenance phase hemostasis is monitored relative to maintaining balanced hemostasis.
1. A method for monitoring hemostasis in a connection with a recipient of an artificial surface device, the method comprising the steps of:
monitoring hemostasis of the recipient in a pre- and intra-operative phase relative to preventing clot formation to achieve artificial surface patency;
monitoring hemostasis of the recipient in a post operative phase relative to bringing about clot formation to achieve vascular recovery;
monitoring hemostasis of the recipient in a stabilizing intensive care phase relative to balancing hemostasis toward an anti-coagulation bias; and
monitoring hemostasis of the recipient in a maintenance phase to maintain balanced hemostasis.
2. The method of claim 1 , wherein the step of monitoring hemostasis in a pre- and intra-operative phase comprises determining an anti-thrombin deficiency of the recipient.
3. The method of claim 1 , wherein the step of monitoring hemostasis in a pre- and intra-operative phase comprises determining an intra-operative coagulopathy of the recipient.
4. The method of claim 1 , wherein the step of monitoring hemostasis in a pre- and intra-operative phase comprises determining a surgical bleeding condition of the recipient.
5. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a post operative phase comprises determining a post protamine coagulopathy of the recipient.
6. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a post operative phase comprises determining a surgical bleeding condition of the recipient.
7. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a post operative phase comprises determining a hypothermia condition of the recipient.
8. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a post operative phase comprises determining a chest tube draining condition of the recipient.
9. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a stabilizing intensive care phase comprises determining a heparin-induced thrombocytopenia condition of the recipient.
10. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a stabilizing intensive care phase comprises determining an anti-thrombin condition of the recipient.
11. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a stabilizing intensive care phase comprises determining a prothrombotic condition of the recipient.
12. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a maintenance phase comprises determining a fibrin formation latency period (R) of the recipient.
13. The method of claim 1 , wherein the step of monitoring hemostasis of the recipient in a maintenance phase comprises determining a prothombotic condition of the recipient.
14. An apparatus for monitoring hemostasis in a connection with a recipient of an artificial surface device, the apparatus comprising:
means for monitoring hemostasis of the recipient in a pre- and intra-operative phase relative to preventing clot formation to achieve artificial surface patency;
means for monitoring hemostasis of the recipient in a post operative phase relative to bringing about clot formation to achieve vascular recovery;
means for monitoring hemostasis of the recipient in a stabilizing intensive care phase relative to balancing hemostasis toward an anti-coagulation bias; and
means for monitoring hemostasis of the recipient in a maintenance phase to maintain balanced hemostasis.
15. The apparatus of claim 14 , wherein each of the means for monitoring comprises a hemostasis analysis device.
16. The apparatus of claim 15 , wherein the hemostasis analysis device comprises a processor and a memory coupled to a testing station, the processor being responsive to a control program stored within the memory for directing operation of the testing station and to obtain and analyze data from the testing station to provide at least one hemostasis parameter.
