Different studies have previously described the association between fetal well-being and gestational sac characteristics. Yolk sac fi rst appears at 5 weeks gestation and becomes visible by ultrasound, while the fetal heart rate appears at 6 weeks gestation and these can be used as prognostic parameters for fi rst-trimester outcomes in pregnancy. Study aim : Relation of the ultrasound parameters in early pregnancy (gestational sac size, yolk sac, and embryonic cardiac activity) to early fetal demise. Patients and methods : This was a hospital-based cross-sectional study conducted in the outpatient clinic and Emergency Department e Obstetrics and Gynecology Department e El Monera General Hospital on 100 pregnant women in their fi rst trimester. Patients were subjected to general examination and abdominal and local clinical examination. Result : Gestational sac diameter at different gestational ages was signi fi cantly higher among the ongoing pregnancy group compared with the pregnancy loss group. Conclusion : Based on our fi ndings we concluded that yolk sac diameter, gestational sac diameter, Crown-rump length in different gestational ages, and cardiac activity at sixth and seventh weeks were signi fi cantly higher among the ongoing pregnancy group; yolk sac diameter, gestational sac diameter, and fetal heart rate were signi fi cant predictors for pregnancy loss.","PeriodicalId":256725,"journal":{"name":"Al-Azhar International Medical Journal","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132110703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Levosimendan as an inotropic agent can be used in those patients. Objective : The aim was to assess morbidity and mortality rates up to 6 months following CABG surgery in patients with LVEF equals 35%, who were given levosimendan. Patients and methods : A total of 40 patients with preoperative LVEF less than or equal to 35% who underwent elective CABG were retrospectively analyzed between March 2020 and April 2022 at Al-Azhar University Hospitals. Levosi-mendan was u continuously given as a bolus-free infusion at a rate of 0.05 e 0.2 m g/kg/min before surgery. Hemodynamic and outcome parameters were registered and statistically analyzed. Results : A signi fi cant improvement was recorded in ejection fraction percentage from 32.8 to 35.9% and then 39.4% after 1 week and 6 months, respectively; it was associated with signi fi cant increase in cardiac output from 5.22 to 6.3 l/ min and 6.1 l/min after 1 week and 6 months, respectively. Mean arterial pressure was also increased from 63.44 to 80.4 mm Hg and 84.6 mm Hg after 1 week and 6 months, respectively. Overall, 80% of patients showed no complications, whereas 5% of them had low cardiac output syndrome, 5% needed intra-aortic balloon pump (IABP), 5% rapid atrial fi brillation, and 5% needed reoperation due to bleeding. On the contrary, postoperative (later) complications included the following: severe sternal wound infection in two cases (5%) and chronic atrial fi brillation in one case (2.5%).
