ABSTRACT
Objective To explore the pregnancy outcomes in women whose fetal/embryonic heart rate( FHR) were below 120 beats per minute( bpm) before 8 weeks pregnancy and determine the predictive value of FHR in pregnancy outcome . Methods The laboratory examinations ,clinical data and clinical history of the pregnant women whose FHR were below 120 bpm before 8 weeks pregnancy were retrospectively analyzed . Results When gestational age(GA) was less than 8 weeks ,pregnancy loss was observed in 11 .0% ( 110/998 ) cases with an FHR less than or equal to 120 bpm ,and pregnancy loss occurred in all the cases ( 23/23) with an FHR less than or equal to 70 bpm . The proportions of first trimester loss were 86 .4% (19/22) for pregnancies with an FHR of 71 －80 bpm ,75 .7% (28/37) for pregnancies with an FHR of 81－90 bpm ,25 .5% (14/55) for pregnancies with an FHR of 91 －100 bpm , 6 .3% (13/208) for pregnancies with an FHR of 101 －110 bpm ,and 2 .0% (13/653) for pregnancies with an FHR of 111 －120 bpm .ROC analysis showed that the best cut-off value to predict adverse pregnancy outcomes was an FHR of 94 bpm . The area under the ROC curve was 0 .906 ( P ＜ 0 .0001 ) and its sensitivity and specificity values were 97 .86% and 71 .43% respectively . Conclusions Fetal/embryonic heart monitoring before 8-weeks pregnancy can be an effective predictor for early pregnancy outcome . The best cut-off value to predict adverse pregnancy outcomes is an FHR of 94 bpm .
ABSTRACT
Objective To carry out health education nursing intervention mode for patients with hemodialy-sis,and to study and analyze the clinical nursing effect.Methods 112 cases of hemodialysis patients were randomlydivided into the observation group and the control group according to random number table,56 cases in each group. The patients of the control group were given conventional nursing model,and the patients of the observation group were given nursing intervention model on the basis of health education.The blood pressure,the internal fistula blockage, indwelling catheter caused by the incidence of infection and blood phosphorus level of compliance rate were compared in the two groups.Results After nursing intervention,diastolic blood pressure(76.17 ±7.02)mmHg and systolic blood pressure (131.17 ±8.77)mmHg of the observation group were significantly better than the control group [(90.91 ±8.44)mmHg,(141.29 ±7.08)mmHg],there were statistically significant differences(t =10.49,13.75, all P <0.05).The incidence rate of fistula obstruction (1.79%)and the catheter infection incidence rate(1.79%) of the observation group were significantly lower than the control group (28.57%,26.79%),there were statistically significant differences(χ2 =8.22,9.17,all P <0.05).The blood phosphorus level standard rate(60.71%)of the observation group was significantly higher than the control group(33.93%),there was statistically significant differ-ence (χ2 =11.45,P <0.05).Conclusion The incidence of complications is significantly decreased after nursing intervention of health education in patients with hemodialysis,and the indexes are improved significantly,and there is no obvious conflict of interest.
