THE VALIDITY OF CONTINUOUS AUTOMATED FLUID MONITORING DURING ENDOMETRIAL SURGERY - LUXURY OR NECESSITY

Thirty-four consecutive women undergoing endometrial laser ablation, a s a treatment of menorrhagia, were recruited to assess the validity of fluid absorption monitoring by a new continuous automated system (Aqu aSens),The same group of women also had monitoring of fluid absorption carried out by our standard technique of weighing. The intra-class co rrelation coefficient for the fluid deficit estimated by AquaSens comp ared to our standard technique of manually weighing the irrigation bag s was 0.98 (95% CI 0.96-0.99). Aquasens therefore provides a valid and non-invasive method of continuously monitoring fluid deficit amongst patients undergoing operative hysteroscopy procedures, thereby reducin g the risk of unexpected fluid absorption and its potentially fatal se quelae.
