摘要
目的探讨腹部超声引导下胚胎移植定位患者饮水量与膀胱容量的关系。方法依据子宫在盆腔中的不同解剖位置,将患者分为A组(子宫前倾前屈位)、B组(子宫水平位)和C组(子宫后倾后屈位)三组;每组分别饮水500mL、800mL和1 100mL,比较三组膀胱容量及在超声引导下子宫显像的清晰度、导尿以及宫颈钳使用的情况。结果三组相同饮水量者膀胱容量比较,差异无统计学意义(均P>0.05)。饮水量500mL时B组超声引导下子宫显影清晰、C组71.43%子宫显影清晰;饮水量800mL时A组94.12%子宫显影清晰;三组饮水量1 100mL的患者均出现有导尿情况,A组14.71%使用宫颈钳辅助胚胎移植。结论前倾前屈位子宫者饮水量800mL、水平位及后屈后倾位子宫者饮水量500mL较适宜。护理人员在患者进行胚胎移植前,应重视了解患者子宫在盆腔中的具体位置,并做好术前排空膀胱再饮水以及不同饮水量的指导工作。
Objective To investigate the relationship between fluid intake volume and bladder volume during transabdominal ultrasound-guided embryo transfer. Methods Due to the anatomical location of the uterus, patients were divided into three groups： anteflexed, horizontal, and retroverted. All groups were asked to drink 500 mL, 800 mL and 1 100 mL of water respectively. Bladder volume, clarity of the images, urinary catheterization, and use of cervical forceps were compared among the three groups. Results There was no significant difference in bladder volume among the three groups when they drank a same volume of water （P〉0.05 for all）. Optimal image quality was achieved in 71.43% of retroverted group patients when they drank 500 mL of.water and in 94.12% of anteflexed group patients when they drank 800 mL of water. All patients needed urinary catheterization when they drank 1 100 mL of water. About 14.71% of patients in the anteflexed group required cervical forceps to assist embryo transfer. Conclusion Before ultrasound-guided embryo transfer, patients with anteflexed uterus should drink 800 mL of water and those with horizontal or retroverted uterus can drink 500 mL. Nurses should pay attention to the exact location of the uterus of patients receiving embryo transfer, and provide education on urination and fluid intake.
