Is known that pregnant women, who for various reasons have a loss of amniotic fluid, many hours or days before the birth of the fetus, are exposed to an infection of the fetus, both of same woman, infection known as the Corio Amniotitis or in an Endometritis which can even lead to Peritonitis, much has been said then about the importance of these membranes to prevent losing amniotic fluidas they represent a physical barrier against infection, but also in his composition there are elements such as enzymes that prevent infection, becoming a biochemical barrier that defends the fetus of an infection. In order to determine in that measured the presence of membranes oocyte intact is a safety factor in pregnant women at term or warranty in the asepsis of the amniotic fluid was performed microbiologic study of 60 samples of amniotic fluid, in patients with term pregnancy, some without of labor and some in full work all with membranes oocyte intact in childbirth, the present work was developed in obstetrics services and laboratory clinic of the Hospital Central of the North Almanzor Aguinaga Asenjo of Essalud in Chiclayo Peru,
In the period between January and April 1990 all patients were Cesarean and samples were obtained in full surgical Act, by direct puncture of the membranes oocyte2 of the 60 samples were positive, the isolated germs were Staphylococcus aureus in a sample (of the group that was into labor) and Enterobacter cloacae in another sample, the group that was not into labor. The results allow us to draw the following conclusions 1.-the amniotic taken under aseptic conditions it was completely sterile in 58 cases and presented germs in two of them which means a pollution in 3.3% of cases and that is mostly a sterile liquid. 2.-two positive cultures one corresponded to sample taken in the first period of the labor, i.e. at the stage latent in the work of childbirth itself. 3.-No direct relationship of coitus was evident in the last month of pregnancy in the genesis of positive cultures of amniotic fluid, which rules out this reason stop to explain the presence of microbes in amniotic fluid. 4.-A possible direct relationship between vaginal tact and genesis of positive cultures of liquid aniotico, because the two amniotic fluid samples that were positive corresponded to pregnant women in the last month of pregnancy who performed vaginal touches prior to surgical intervention.
