Our objectives were to document the causes of fluid absorption during continuous flow hysteroscopy and to determine under which operative conditions fluid overload may occur.
Fifteen patients underwent operative hysteroscopy with 2% ethanol solution for uterine distention. Absorption of fluid was measured by blood alcohol, sodium, osmolarity, and hematocrit. Intrauterine pressures were measured with an obstetric pressure catheter.
Alcohol absorption was noted in one patient during a myoma resection. Two additional patients, not in the study, had fluid absorption after partial perforations of the uterus. Under normal operative conditions there were no changes in sodium, osmolarity, or hematocrit. Intrauterine pressures ranged from 45 to 75 mm Hg. Experimental pressures of greater than 200 mm Hg were not associated with fluid absorption.
Intravasation of fluid may occur through open uterine venous channels with extensive resections and under low pressures in the presence of unrecognized perforations.
我们的目的是记录连续流动宫腔镜检查期间液体吸收的原因，并确定在哪些手术条件下可能发生液体过载。
15例患者接受了使用2%乙醇溶液进行子宫扩张的手术宫腔镜检查。通过血液酒精、钠、渗透压和血细胞比容测量液体吸收情况。使用产科压力导管测量宫内压力。
1例患者在肌瘤切除术中出现酒精吸收。另外2例未纳入研究的患者在子宫部分穿孔后出现液体吸收。在正常手术条件下，钠、渗透压或血细胞比容没有变化。宫内压力范围为45至75毫米汞柱。大于200毫米汞柱的实验压力与液体吸收无关。
在存在未被识别的穿孔且压力较低的情况下，进行广泛切除时，液体可能通过开放的子宫静脉通道进入血管。
