目的

建立早孕期超声检查的存图标准,并验证其应用效果。

方法

采用北京协和医院产科专业组制定的早孕期超声检查存图标准,该标准共包括4个标准切面:胎囊-宫体-宫颈纵切面、胎囊-宫体横切面、胎芽头臀长切面和双侧卵巢/附件区切面。2022年5月至6月对33位住院医师进行早孕期超声检查存图标准的规范化培训,并分别调取培训学员2021年11月至2022年4月(培训前)及2022年7月至12月(培训后)的早孕期超声报告20~30份/人,采用t检验对比培训前后早孕期超声检查标准化存图率的差异。

结果

抽取培训前早孕期超声报告共789份,其中胎囊-宫体-宫颈纵切面存图合格率为(46.1±27.7)%、胎囊-宫体横切面存图合格率为(89.2±4.2)%、胎芽头臀长切面存图合格率为(93.0±40.1)%、双侧卵巢/附件区切面存图合格率为(58.2±27.8)%。抽取培训后早孕期超声报告共795份,胎囊-宫体-宫颈纵切面存图合格率为(84.9±15.8)%、胎囊-宫体横切面存图合格率为(97.8±3.3)%、胎芽头臀长切面存图合格率为(94.1±34.7)%、双侧卵巢/附件区切面存图合格率为(79.5±19.5)%。其中胎囊-宫体-宫颈纵切面及双侧卵巢/附件区切面存图合格率高于培训前,差异具有统计学意义(t =-6.896、-3.315,P均<0.001)。

结论

早孕期超声检查标准化存图培训可显著提高早孕期超声检查的标准化存图合格率,保障了孕期及围产期医疗质量安全。

Objective

To establish a standard ultrasound examination protocol for early pregnancy and verify its application effectiveness.

Methods

A standard ultrasound examination protocol for early pregnancy was developed by experts in Peking Union Medical College Hospital. The standard consists of 4 standard sections:the uterine cervical longitudinal section, the uterine transverse section, the fetal bud (head buttock length) section,and the bilateral ovarian section. Thirty-three residents underwent training of this protocol from May to June 2022,and 20-30 early pregnancy ultrasound reports were collected from each resident from November 2021 to April 2022 (before training) and from July to December 2022 (after training) separately. The t-test was used to compare the difference in the quality of ultrasound reports before and after training.

Results

Seven hundred and eightynine ultrasound reports of early pregnancy were selected before training. The qualified rate of the ultrasound reports for different imaging sections was: the uterine cervical longitudinal section, (46.1±27.7)%, the uterine transverse section: (89.2±4.2)%, the fetal bud (head buttock length) section: (93.0±40.1)%, and the bilateral ovarian section:(58.2±27.8)%. Seven hundred and ninety-five ultrasound reports of early pregnancy were selected after training.The qualified rate of the ultrasound reports for different imaging sections was: the uterine cervical longitudinal section, (84.9±15.8)%, the uterine transverse section: (97.8±3.3)%, the fetal bud (head buttock length) section:(94.1±34.7)%, and the bilateral ovarian section: (79.5±19.5)%. The qualified rates of the reports in the uterine cervical longitudinal section and bilateral ovarian section after training were significantly higher than those before training (t=-6.896 and -3.315, respectively; both P<0.001).

Conclusion

Training on early pregnancy ultrasound examination can significantly improve the qualified rate of standardized ultrasound reports, ensuring the medical quality and safety of prenatal ultrasound examination.
