AIM: To estimate the effect of 0.9% saline during bipolar resectoscopy and 1.5% glycine during monopolar resectoscopy on hemodynamic, biochemical and hematological parameters.
MATERIAL & METHODS: A prospective randomized study in a tertiary care university hospital and comprising of 155 patients scheduled for hysteroscopic myomectomy. They were subjected to bipolar resectoscopic myomectomy utilizing 0.9% saline in group A, and monopolar resectoscopic myomectomy utilizing 1.5% glycine in group B. Perioperative measurements of hemodynamic, hematological, and biochemical changes in all cases were reported. Likewise, intrauterine pressure throughout the different procedures was recorded.
MAIN OUTCOME MEASURES: intraoperative difference with regards to fluid volume and subsequent systemic changes specially osmolarity.
RESULTS: A significant increase of central venous pressure, end diastolic volume, end diastolic index, stroke volume, stroke index, cardiac output, cardiac index, postoperative prothrombin time and postoperative partial thromboplastin time in both groups with positive correlations between the absorbed fluid volume and these measurements in both groups. Moreover, there was a significant decrease in systemic vascular resistance, postoperative hemoglobin concentration, postoperative hematocrit value ratio, postoperative platelet count and postoperative prothrombin concentration in both groups and there were negative correlations between the absorptive fluid volume and these measurements in both groups. There were significant decrease in serum sodium concentration and postoperative serum osmolarity in glycine group (B) with negative correlations between the absorptive fluid volume and both serum sodium concentration and serum osmolarity in glycine group (B).
CONCLUSIONS: The use of bipolar resectoscope utilizing 0.9% saline as a distention media is not associated with hyponatremia or hyposmolarity unlike monopolar resectoscope utilizing 1.5% glycine distending media in cases with submucous myoma of considerable size.
