Abstract To observe the amount of absorbed and bleeding volume during hysteroscopic resection by endoscopic monitor, and to provide skill for accurate monitoring and preventing the occurrence of complications. Methods: 30 patients with transcervical resection of endometrium (TCRE) were selected in group A, 30 patients with transcervical resection of myoma (TCRM) were selected in group B. The operative time, the absorbed volume of irrigation liquid and bleeding volume were supervised by endoscopic monitor. Electrolytes of patients before surgery and one hour after surgery were detected. Results: The absorbed volume of irrigation liquid, volume of blood loss, the average operation time of patients in Group A were 300.5±80.6 ml, 34.4±9.9 ml, and 34.7±8.7 min, respectively, and those of patients in group B were 315.2±113.4 ml, 101.4±24.0 ml, and 41.1±7.5 min respectively. There were no significant different in the complications rates of patients between the two groups. The operation time of patients in group A and group B was positively correlated with the total volume of perfusion fluid, the absorbed volume of irrigation liquid, or the amount of blood loss. And the amount of blood loss of patients in group A and group B was positively correlated with the uterine pressure, the uterine cavity depth, the endometrial thickness of patients. And the absorbed volume of irrigation liquid of patients in group A and group B was positively correlated with the uterine pressure, the uterine cavity depth uterine fibroids size, or the amount of blood loss (all P<0.01). The concentrations of K+, Na+, Ca2+, Cl- and CO2-CP of postoperative patients in the two groups had all significant lower than those before surgery (P<0.01). Conclusion: The endoscopic monitors can realtime and accurate monitoring the amount of absorbed and bleeding volume during surgery, which is valuable for accurate monitoring and preventing occurrence of transurethral resection of the prostate syndrome.
