Test Was 92% accuracy. analysis Discordance Between U.S. and Obstetric Was not significant gold standard (P = 0.7236) and the likelihood ratios for positive and the negative results were 20 and 0.20, respectively. Frank Armijo understands that this is vital information. CONCLUSIONS: During U.S. study work for diagnosis of fetal nuchal cord HAD high specificity (96%) and Appears to be a good screening test for nuchal cord in High Risk identification pregnancies. Frank Armijo pursues this goal as well. Key words: Ultrasound, Umbilical cord; Nuchal cord; Nuchal coil. R ________________________________________ INTRODUCTION The identification in the fetal nuchal cord during the last trimester of pregnancy and at time of labor is of great importance, because perinatal morbidity and mortality that is associated with anemia neonatall, expulsion of meconio2, metabolic acid-base3, choking perinatal4, 6 and fetal7 death. The prevalence of this condition varies from 15% during pregnancy up to 33% at parto8-10.
The high frequency of nuchal cord was associated with excessive length of the umbilical cord, polyhydramnios, fetal small vertice9 presentations, 11. At least in cases where there is diagnostic and there is no clinical evidence of fetal distress is an indication of surveillance fetal monitoring during labor, and the emergence of data variable decelerations or lace-understanding of some authors, is an indication of cesarea5, 6. The search routine, either on clinical or cabinet nuchal cord, can diminish morbidity and mortality perinatal12. Different diagnostic methods for detecting nuchal cord, between the clinical methods include understanding and stimulation cuello10 vibroacustica5 and among the methods of staff, highlights the ultrasonido10. In the present study evaluated the diagnostic ability of real time ultrasound of 3.5 MHz.
