氧疗在胎儿磁共振成像检查中的应用及效果评价

Application and Effect Evaluation of Oxygen Therapy in Fetal Magnetic Resonance Imaging

目的探索氧疗在胎儿MRI检查中的应用效果。方法选取210例因超声检查怀疑胎儿异常申请MRI检查的孕妇为研究对象,随机分为对照组和观察组。对照组102例,接受常规检查准备;观察组99例,除接受常规检查准备外,给予检查前面罩、检查中鼻导管常压氧疗。评价指标:一次检查成功率、检查完成所需时间、检查中指尖脉搏和影像质量。结果观察组孕妇氧疗后:(1)孕妇的一次检查成功率为95.96%,明显高于常规组的81.37%;(2)孕妇完成检查所需时间(24.76±1.04)min,明显低于常规组的(31.28±2.59)min;(3)孕妇检查中指尖脉搏(105.80±4.52)次/min,明显低于常规组的(116.94±8.92)次/min;(4)影像质量主观评分(3.23±0.73)分,明显高于常规组的(2.78±0.63)分。结论氧疗对于提高孕妇检查配合度、缩短检查时间等有着重要价值,提高孕妇检查配合度及效率,保障了高质清晰图像的获取与精准诊断结果的出具,降低了医疗风险。

Objective This study is to explore the effect of oxygen therapy in fetal magnetic resonance imaging.Methods 210 pregnant women from a hospital in Leshan City are selected as the research subjects whose magnetic resonance examination results indicate fetal abnormalities by using ultrasound examination tools.The study subjects are randomly divided into control group and observation group.A control group consists 102 patients who receives routine examination preparations.The observation group involves 99 patients,and its preparations comprise atmospheric oxygen therapy with mask before examination,atmospheric oxygen therapy with nasal catheter during examination and routine examination preparations.Evaluation indicators:success rate of one examination,time required to complete the examination,fingertip pulse during examination,and image quality.Results The pregnant women in the observation group receives oxygen therapy:(1)the success rate of a single examination in pregnant women is 95.96%,which is significantly higher than 81.37%in the conventional group;(2)The time required for pregnant women to complete the examination is(24.76±1.04)min,which is dramatically lower than the(31.28±2.59)min of the conventional group;(3)The fingertip pulse of pregnant women is(105.80±4.52)times/min,which is obviously lower than(116.94±8.92)times/min of the conventional group;(4)The subjective score of image quality is 3.23±0.73,which is significantly higher than(2.78±0.63).of the conventional group.Conclusions Oxygen therapy is of great value to improve the image quality,and to shorten the time of fetal magnetic resonance examination.Oxygen therapy can improve the coordination and efficiency of pregnant women's examination,ensuring the acquisition of high-quality clear images and the issuance of accurate diagnosis results,and reducing the medical risks.
