Fluid deficit-related complications in hysteroscopic surgery using normal saline as distension medium: a retrospective analysis of four surgical modalities and risk factors

The authors aimed to compare fluid deficit volumes across four hysteroscopic procedures using normal saline as a distension medium and to identify risk factors for excessive fluid deficit. They found that transcervical resection of myoma (TCRM) had the highest fluid absorption and associated complications, with factors such as FIGO type 2 myoma, prolonged operative time, and higher distension pressure being significant predictors of excessive fluid deficit. The study suggests that using a lower intrauterine pressure of 80 mmHg may be a safer approach during TCRM, although the findings require further prospective validation.
