Hyponatremia - hyperhydration during hysteroscopy

Objective. To determine the rate of excessive intravasation of the dielectric fluid hyponatremia-hyperhydration (HH) and to improve methods for its prevention in patients with intrauterine abnormalities (IA). Subject and methods. The rate of HH during hysteroresectoscopic interventions was studied in 550 patients with IA (submucous uterine myoma, endometrial polyps, intrauterine synechiae, and abnormal uterine bleedings). The results of operative hysteroscopies carried out at two gynecology units, S.P. Botkin City Clinical Hospital, in 2012 to 2013 were studied by the Innovation Department of Mini-Invasive Technologies, V.I. Kulakov Research Center of Obstetrics, Gynecology, and Perinatology, Ministry of Health of the Russian Federation. The findings were processed using a package of Statistica programs for Windows 6.0 Stat-Soft. Results. No HH cases were observed during hysteroresectoscopic interventions made in 550 patients aged 18 to 80 years. The volume of the fluid spent in our investigation for hysteroresectoscopy averaged 4.0 to 8.0 liters. The intervention was stopped when intravasation needed more than 1500 ml. The main stage of the surgical intervention (from the insertion of a hysteroscope to the completion of resection) lasted 4 to 15 min. The duration of surgical treatment with resection technology was 30-35 minutes. Blood loss did not exceed 50 ml in any case.
