妇产科应用纤维子宫内窥镜作诊断检查时,需要有较好的膨宫液,以膨起宫腔便于窥视。我们为满足临床的需要,根据子宫腔的生理特点和内窥镜操作技术的要求,对膨宫液按下列条件进行了筛选配制:(1)无毒性,无刺激性,无药理和生理活性,无菌和无热原;(2)等渗,能被机体组织吸收;(3)有一定粘滞度以减少由两侧输卵管流失;(4)具有一定的传光转象性,能使闭合的宫腔膨起,给检视者创造一个清晰可视的空间。我们曾用高渗葡萄糖液等进行筛选,经动物实验和临床应用认为以羧甲基纤维素钠配的膨宫液,膨宫效果好,流失量少,腹痛发生率较50%葡萄糖液等有明显降低。用羧甲基纤维素钠配制膨宫液有3种处方:
Obstetrics and Gynecology fiber endoscopy for diagnostic tests, you need to have a good uterine fluid to the uterine cavity for easy peep. We meet the clinical needs, according to the physiological characteristics of the uterine cavity and endoscopic technology requirements, the uterine fluid was selected according to the following conditions: (1) non-toxic, non-irritating, pharmacological and physiological activity, Aseptic and pyrogen-free; (2) isotonicity, can be absorbed by the body tissue; (3) a certain viscosity to reduce the loss of tubal from both sides; (4) The uterine bulge, to the viewer to create a clear visual space. We have used hypertonic glucose solution for screening, animal experiments and clinical applications that the sodium carboxymethyl cellulose with uterine fluid, swelling Palace effect, less loss, the incidence of abdominal pain than 50% glucose solution, etc. Obvious reduction. There are 3 prescriptions for formulating uterine fluid with sodium carboxymethylcellulose:
