Summary for Patent: 7,041,275
Title: | Irrigating fluid |
Abstract: | A surgical irrigating fluid composition, especially for endoscopic surgery, is provided comprising a rinsing fluid and nitrous oxide added as a marker to the rinsing fluid in an amount which is detectable in the expired breath from a mammal, especially man, that is subjected to the surgery. |
Inventor(s): | Hahn; Robert (Tullinge, SE) |
Assignee: | Hahn; Robert (Tullinge, SE) |
Application Number: | 10/472,943 |
Patent Claims: | 1. A method of monitoring the amount of irrigating fluid composition which is absorbed during surgery in a mammal, including man, comprising utilizing an irrigating
fluid composition comprising nitrous oxide as a marker in a detectable amount, and monitoring the expired breath from said mammal by means of a nitrous oxide detector to detect the amount of nitrous oxide therein.
2. A method according to claim 1 wherein said surgery is endoscopic surgery. 3. A method according to claim 2 wherein said endoscopic surgery is conducted in the genitourinary tract. 4. A method according to claim 3, wherein endoscopic surgery in the genitourinary tract is a transurethral resection or transcervical resection of the endometrium. 5. A method according to claim 1 wherein said irrigating fluid composition comprises sterile water and nitrous oxide as a marker. 6. A method according to claim 1 wherein said irrigating fluid composition contains a solute for inhibiting hemolysis. 7. A method according to claim 6 wherein said solute is selected from the group consisting of glycine, mannitol, and sorbitol, and mixtures thereof. 8. A method according to claim 6 wherein said solute is within the range of 0.1 5.0% by weight based on the weight of said irrigating fluid composition. 9. A method according to claim 7 wherein said solute is within the range of 0.1 5.0% by weight based on the weight of said irrigating fluid composition. 10. A method according to claim 6 wherein said solute is within the range of 0.5 2.5% by weight based on the weight of said irrigating fluid composition. 11. A method according to claim 7 wherein said solute is within the range of 0.5 2.5% by weight based on the weight of said irrigating fluid composition. 12. A method according to claim 6 wherein said solute is within the range of 1.0 2.0% by weight based on the weight of said irrigating fluid composition. 13. A method according to claim 7 wherein said solute is within the range of 1.0 2.0% by weight based on the weight of said irrigating fluid composition. 14. A method according to claim 1 wherein the amount of nitrous oxide in the irrigating fluid composition is within the range of 0.1 3.0% by weight based on the weight of said irrigating fluid composition. 15. A method according to claim 6 wherein the amount of nitrous oxide in the irrigating fluid composition is within the range of 0.1 3.0% by weight based on the weight of said irrigating fluid composition. 16. A method according to claim 1 wherein the amount of nitrous oxide in the irrigating fluid composition is within the range of 0.5 2.5% by weight based on the weight of said irrigating fluid composition. 17. A method according to claim 6 wherein the amount of nitrous oxide in the irrigating fluid composition is within the range of 0.5 2.5% by weight based on the weight of said irrigating fluid composition. 18. A method according to claim 1 wherein the amount of nitrous oxide in the irrigating fluid composition is within the range of 0.7 1.5% by weight based on the weight of said irrigating fluid composition. 19. A method according to claim 6 wherein the amount of nitrous oxide in the irrigating fluid composition is within the range of 0.7 1.5% by weight based on the weight of said irrigating fluid composition. 20. A method according to claim 1 wherein said mammal is a human. |
