Randomized Controlled TrialGas embolism during hysteroscopic surgery using bipolar or monopolar diathermia: a randomized controlled trial.
The objective of the study was to determine the incidence and amount of gas embolism during hysteroscopic surgery using either monopolar or bipolar diathermia and to investigate the relationship between the severity of gas embolism and the amount of intravasation of distension fluid. ⋯ During hysteroscopic surgery, gas embolism was equally observed irrespective of the type of diathermia. However, more extensive embolism was observed when intravasation of distension fluid exceeded 1 L. These results question the acceptance of up to 2500 mL intravasation of distension fluid if bipolar diathermia is used.
