[Monitoring of irrigating fluid absorption in transvesical resection of the myometrium].
BACKGROUND
Monitoring of the absorption of irrigating fluid during transcervical resection of the myometrium was studied. Irrigating fluid under pressure was used. Absorption can give symptoms as seen in transurethral resection syndrome.


METHODS
A method using ethanol labelled irrigation fluid measuring ethanol in expired air was used. Serum natrium and absorbed irrigation fluid estimated by weight was measured. A total of 100 women were included. The investigation was part of the daily routine with varying anaesthetists and nurses.


RESULTS
Four patients with an absorption of more than 1200 ml were identified. The end-tidal ethanol and serum natrium deficit were equally accurate in determination of this. In absorption of less than 1200 ml, the serum natrium deficit and end-tidal ethanol were not correlated to absorbed irrigation fluid judged by weighing.


CONCLUSIONS
Determination of the end-tidal ethanol during transcervical resection is recommended as a supplement. The method is non-invasive and simple and can be repeated at any time without interruption of surgery.
