Fluid balance during hysteroscopic surgery

Absorption of irrigating solution may involve serious complications during hysteroscopic surgery. This absorption occurs mainly into the vessels opened during the procedure. Careful perioperative monitoring of the deficit of collected irrigating medium during transcervical surgery is mandatory. Significant absorption seems to be connected with the development of discrete cerebral oedema and nausea, secondary to dilutional hyponatraemia and elevation of several amino acids.
