Abstract

Embodiments of the invention provide a system for temperature control of the human body. The system includes an indwelling catheter with a tip-mounted heat transfer element. The catheter is fluidically coupled to a console that provides a heated or cooled heat transfer working fluid to exchange heat with the heat transfer element, thereby heating or cooling blood. The heated or cooled blood then heats or cools the patient'"'"'s body or a selected portion thereof. In particular, strategies for providing cooling while reducing shivering are disclosed, including administration of various drugs and drug combinations.

Claims

1. A method of changing the temperature of a human body, comprising:

inserting a catheter having a heat transfer element into a vein of a patient;

circulating a working fluid through the catheter and the heat transfer element, the working fluid having a temperature different from the patient temperature;

administering a therapeutic amount of a composition selected from the group consisting of;

meperidine, prodine, fentanyl, an opioid, a therapeutic amount of a (+) beta isomer of a prodine in which the 3-methyl group is replaced with an n-propyl or allyl group, an isomer of a cis-picenadol, a isomer of tramadol, or a isomer of nefopam, whereby shivering is lessened.

2. The method of claim 1, further comprising circulating a working fluid through the catheter and the heat transfer element, the working fluid having a temperature higher than the patient temperature.

3. The method of claim 1, further comprising circulating a working fluid through the catheter and the heat transfer element, the working fluid having a temperature lower than the patient temperature.

25. The method of claim 1, wherein the composition is an isomer of tramadol, and further comprising administering a therapeutic amount of buspirone.

27. The method of claim 1, wherein the composition is an isomer of nefopam, and where in the isomer is the (−

) enantiomer.

28. The method of claim 1 wherein the composition is an isomer of nefopam, and further comprising administering a therapeutic amount of a drug selected from the group consisting essentially of a prodine, meperidine, thorazine, buspirone, clonidine, and tramadol, and combinations thereof.

29. The method of claim 1, further comprising administering a therapeutic amount of a delta opiate receptor antagonist.

16. The method of claim 429, wherein the antagonist is naltrindole or naltriben.

17. A method of changing the temperature of a human body, comprising:

inserting a catheter having a heat transfer element into a vein of a patient;

circulating a working fluid through the catheter and the heat transfer element, the working fluid having a temperature different from the patient temperature;

administering a therapeutic amount of a (+) isomer of a prodine in which a hydroxyl has been added to the phenyl ring, whereby shivering is lessened.

18. The method of claim 17, wherein the hydroxyl is added in the m position.

19. The method of claim 17, wherein the prodine is alpha-allylprodine, and the 3-methyl is replaced with an allyl group.

20. (canceled)

21. (canceled)

22. The method of claim 21, wherein the composition is an isomer of a cis-picenadol, and wherein the isomer is the (−

) enantiomer.

23. The method of claim 21, wherein the composition is an isomer of a cis-picenadol, and further comprising administering a therapeutic amount of a racemic mixture of isomers of a cis-picenadol.
