目的:探讨孕妇侧卧位的角度与纠正枕后位的关系。方法:选择2004年1月～2010年1月于牡丹江医学院附属二院妇产科分娩经彩超及产科检查确诊为枕后位、无明显产道异常或头盆不称、年龄20～32岁的初产妇200例,随机平均分为观察组和对照组。两组宫缩时均取跪位,宫缩间歇时,观察组同侧俯卧位(同侧俯卧>90°);对照组对侧俯卧位(对侧俯卧>90°且向对侧旋转后儿头枕部超过12:00)。结果:观察组90%转为枕前位经阴道分娩,10%剖宫产;对照组78%转为枕前位经阴道分娩,20%剖宫产。结论:侧卧位的角度与纠正枕后位的成功率关系密切。纠正枕后位时可采取跪位(180°)、同侧俯卧位(>90°)、同侧卧位(90°)、及对侧俯卧位(对侧俯卧>90°且儿头枕部超过12:00);若对侧俯卧<90°或对侧俯卧>90°但儿头枕部不超过12:00,胎儿将继续向枕后位旋转;若对侧俯卧胎儿枕部位于12:00,胎位不变。 Objective: To explore the relationship between the position of the pregnant woman in the lying position and the posterior posterior position of the pillow. Methods: From January 2004 to January 2010, obstetrics and gynecology at the Second Affiliated Hospital of Mudanjiang Medical College was diagnosed as occipitophthalmus by color Doppler ultrasound and obstetric examination. There was no obvious abnormalities in the birth canal or head basin, the age of 20-32 years Initial maternal 200 cases were randomly divided into observation group and control group. The contractions of the two groups were all knees, contractions during the contraction, the observation group ipsilateral prone position (ipsilateral prone> 90 °); control group contralateral prone position (contralateral prone> 90 ° and contralateral spin Head pillow over 12:00). Results: 90% of the observation group were transvaginal delivery in the anterior occipital region and 10% of the cesarean section. In the control group, 78% were transvaginal delivery in the anterior occipital region and 20% in the cesarean section. Conclusion: The angle of the lateral position is closely related to the success rate of correcting the posterior position of the occiput. Correct posterior position may take kneeling position (180 °), ipsilateral prone position (> 90 °), ipsilateral lying position (90 °), and the contralateral prone position (contralateral prone position> 90 ° and the head pillow More than 12:00); if the contralateral prone <90 ° or contralateral prone> 90 ° but the head of the pillow does not exceed 12:00, the fetus will continue to rotate to the posterior position of the pillow; 00, fetal position unchanged.
