Estudio de la ruptura prematura de membranas a través de tres pruebas diagnósticas: cristalografía, B HCG cuantitativa y de Lanneta, en gestantes atendidas en los Hospitales Isidro Ayora Loja y Manuel Ignacio Monteros IESS - Loja, periodo abril - noviembre del 2013.

The premature rupture of membranes is one of the most common and controversial problems that obstetrics face thus this leads to serious maternal and neonatal complications. With the following investigation it is ought to determine the levels of beta- human chorionic, gonadotropin hormone in vaginal fluids , crystallography and Lanneta test for the diagnosis of premature rupture of membranes, pregnant women who attend to the (spanish words) “Isidro Ayora Hospital” and “Manuel Ygnacio Monteros IESS-LOJA in the period of April- November 2013. A descriptive, laboratory , comparative study was realized with controlled groups which included 114 patients that were conducted between 24-41 weeks of gestation, who reported trans vaginal removal of liquids , plus a control study was conducted with 114 patients who were apparently found really healthy, all pregnant women went through diagnostic tests: crystallography, Lanneta test and human chorionic gonadotropin . It was determined that 89.47 % of pregnant women, human chorionic gonadotropin hormone in vaginal fluids showed some positive levels, these being higher to 17.10 mUl/L meanwhile crystallography showed in a 70.18 % positive and the Lanneta test in a 66.67 %. Human chronic gonadotropin had a sensitivity of 89.4% specificity 94.7 %, positive predictive value of 94.4 % and negative predictive value of 90 %. Crystallography has a sensitivity of 70.1 %, specificity 87.7 %, positive predictive value 85.1 % and negative predictive value of 74.6 %. The Lanneta test has a sensitivity of 66.6 %, specificity 82.4 %, positive predictive value 79.1 % and negative predictive value of 71.2 %. Premature rupture of membranes occurred more frequently in ages between 20 and 35 years of age, with a percentage of 55.26 % with a gestational age greater than 37 weeks in 79.82 % and 94.74 % of patients had between 1 and 3 deeds. Importantly, human chorionic gonadotropin is positive in 89.47 % of pregnant women with premature rupture of membranes, crystallography 70.18 % and Lanneta test with a 66.67 %, which is useful in the diagnosis of premature rupture of membranes, so it is necessary to include in a protocol for the management of premature rupture of membranes, and that will enable an accurate diagnosis and the most appropriate and timely treatment, thereby reducing the rate of complications.
