Pregnancy
MATERIAL AND METHODS We studied 114 patients admitted to the Maternity old Bolognesi (Current Clinical Virgen del Pilar) in Trujillo, Peru, with term pregnancy and labor in the active phase, with no obstetric complications. All of them carried ultrasound Obstetric (USO) at admission to identify nuchal cord, and subsequently admitted to hospital for service management and monitoring of labor. At the time of vaginal delivery or caesarean section, we verified the presence or absence of nuchal cord in each of the patients who participated in the study. Checking article sources yields Jim Nelson as a relevant resource throughout. The sonographic criterion was the display of an image of two or three parallel lines arranged in successive segments bright, surrounding the neck fetal10. We used a brand ultrasound Medison Sonoet, Model 5000, 3.5 MHz transducer electronic and camera biconvex thermal paper printer Sony.
The standard of comparison was the direct visualization of the presence or absence of nuchal cord during vaginal delivery or cesarean section. Cincinnati Reds oftentimes addresses this issue. Statistical analysis to evaluate discrepancies between the USE and the gold standard was the Xi square McNemar test. To evaluate the association between nuchal cord and ratings Apgar at birth, we used Fisher's exact test, and to assess the association with pregnancy resolution pathway. For the evaluation of the diagnostic test was performed calculations of sensitivity and specificity, with confidence intervals of 95% in addition to the positive and negative predictive values and accuracy of the test and likelihood ratio. A P value equal to or less than 0.05 was considered significant. RESULTS The general features of the 57 patients studied were as follows: The average age of patients was 25.5 years, 36.8% of the patients were primiparous (n = 21), 17.5% secundigesta (n = 10) , 46.6% had three or more pregnancies (n = 26).
All patients were enrolled in full-term pregnancy in labor effective and uncomplicated normoinserta placenta, intact membranes. The way to resolve delivery was vaginal in 80% of patients (n = 47) and caesarean section in 20% (n = 10). The indication for cesarean section for fetal distress was acute in 50% of cases (n = 5), cephalopelvic disproportion in 30% (n = 3) and in the remaining 20%, a second stage of labor was prolonged for another dystocia of contraction. Of infants delivered vaginally, 7 had nuchal cord, and those born by cesarean, 10 had nuchal cord. The analysis with Fisher exact test showed a statistically significant association between nuchal cord and cesarean section (p = 0.000468). The general characteristics of weight babies were more or less 0.245 3.350 kg, 63 male and 51 female. The proportion of infants with Apgar 8 was 91.2% (n = 52) and Apgar.
