PPRM is the main cause of premature labor.
After premature rupture of fetal membranes, easily cause relevant complication, for example: a. causes puerperal infection, infection of newborn, the septicemia of parent; B. preemie, and pregnant week is more early, and the risk of chorioamnionitis is larger, due to the various complication that premature does not become and intrauterine infection causes, comprises respiratory distress syndrome of newborn, intraventricular hemorrhage and NEC etc. Find early rupture of membranes, and pregnant woman and fetus carried out to corresponding diagnosis and treatment and processing have important meaning for controlling relevant complication.
The most direct evidence of rupture of membranes is to have amniotic fluid to spill, and checks that in vagina, whether having amniotic fluid to spill can be used as the foundation that judges rupture of membranes. The pH of normal vagina is 3.8-4.5, even under serious inflammatory conditions, pH is also between 5.5-6.0; But the pH of amniotic fluid is 7.0-7.5 is alkalescent, when rupture of membranes, amniotic fluid can make vaginal secretion pH >=6.5 after flowing out. General pH test paper o'clock presents green to blue in pH >=6.5, pH≤6.0 present yellow to red. PH test paper is contacted with vaginal secretion, if test paper present blueness can clarify a diagnosis amniotic fluid flow out.
Whether the pH value of test vaginal fluid, have amniotic fluid to flow out the phenomenon that can judge whether to have occurred premature rupture of fetal membranes by diagnosis. But because pH test paper is originally as filter paper material, there is sharper edge, adopt the method for pH test paper test amniotic fluid, while putting into vagina, may be damaged to vagina mucosa, bring discomfort to pregnant woman; Easily deliquescing is easily rotten again in the time running into liquid for pH test paper, is difficult to go deep into vagina inside, and the interference causing is larger; In addition, utilize pH test paper test amniotic fluid, the transfer of indicator easily occurs; PH test paper uses inconvenient, and is vulnerable to pollute; PH test paper is subject to the impact of storage environment large, and the term of validity is short, thereby affects test result.
CN200620083734.1 discloses a kind of disposable premature rupture of fetal membranes pH test paper diagnosis rod, but its susceptibility is not high. And similarly premature rupture of fetal membranes perception pad or hip nursing pad are to flow out at amniotic fluid or vaginal fluid that pregnant woman is external just to be detected, cannot realize timely understanding premature rupture of fetal membranes situation. Have and disclose the kit for detection of premature rupture of fetal membranes carrying out based on anti-human IGFBP-1 monoclonal antibody, anti-mouse polyclonal antibody, as CN103293310B, CN103175968A etc. Such as this type of kit of CN103293310B in use, often need first to sample, then by sample to be tested by processing such as air-dry, confining liquid cultivations, then contact, react with detecting liquid, its step is comparatively loaded down with trivial details, detects consuming time longer; In the kit of CN103175968A, be to have adopted test strip, although on the time, can shorten compared with the former, when the mode of test strips is put into vagina, may be damaged to vagina mucosa, bring sense of discomfort to pregnant woman, meanwhile, test result also may be subject to the interference of urine and affect accuracy. Based on the detection method of IGFBP-1 and placenta α microglobulin 1, often apply to clinical. And practical situations shows, use pH test paper method of testing and micro-method of testing to be difficult to the situation of definite premature rupture of fetal membranes, and the vacation sun rate that these two kinds of methods occur regular uterine contraction and intact fetal membranes person is up to 19%-30%.
