Amnioscopic examination

Amniocentesis is the use of amniotic membrane to observe the amniotic fluid during pregnancy or childbirth, to determine the safety of the fetus. The subject took the bladder lithotomy position, routinely disinfected the vulva and laid a sterile hole towel. Expose the cervix with a vaginal speculum, disinfect the cervix and vagina with 0.5% povidone iodine, wipe the mucus in the cervix and cervical canal, and remove the mucus with 2.5% NaHCO3 solution if necessary. Adjust your emotions before the test to prevent the test results from being affected by excessive stress. Basic Information Specialist classification: maternity check check classification: biochemical examination Applicable gender: whether women are fasting: not fasting Tips: Inappropriate people: placenta previa, threatened premature delivery, temple first exposed, less than 37 weeks of pregnancy, the fetus is not mature, normal value The amniotic fluid is clear, colorless and transparent. It can be seen through the tires and the fetal hair is shattered in the amniotic fluid and visible white bright fetus. Clinical significance Abnormal results. 1, suspicious fetal distress, amniotic fluid is pale yellow, translucent, visible fetal fat, hair is faintly visible (amniotic fluid is I degree turbid). 2, fetal distress, amniotic fluid is yellow or yellow-green (amniotic fluid II degree turbid), even dark green (amniotic fluid is III degree turbid) 3, in the fetal death palace, amniotic fluid reddish brown, turbid like gravy. 4, placental abruption, amniotic fluid is pink or bright red. 5, maternal and child blood type does not fit intrauterine hemolysis, amniotic fluid is yellow or golden yellow 6, the membrane rupture, can directly see the first exposed part of the fetus, the former sheep water bladder collapsed, and the first exposed part of the fetus (the disappearance of the former amniotic fluid), amniotic fluid overflow in the amniotic lens tube. 7, no brain children (head first exposed), visible fetal first exposed, the former sheep water bladder collapsed, and the fetus first exposed close (pre-amniotic water disappeared), amniotic lens tube with amniotic fluid overflow. The high-risk pregnancy and the pregnant women who have fetal distress signs or placental dysfunction are suspected of having an expired pregnancy, suspected premature rupture of membranes, no amniotic fluid outflow, and suspected amniocentesis after amniocentesis. Precautions Taboo before the test: Adjust your emotions before the test to prevent the test results from being affected by excessive stress. Requirements for inspection: Actively cooperate with the doctor. Inspection process 1. The subject takes the bladder lithotomy position, routinely disinfects the vulva and lays a sterile hole towel. Expose the cervix with a vaginal speculum, disinfect the cervix and vagina with 0.5% povidone iodine, wipe the mucus in the cervix and cervical canal, and remove the mucus with 2.5% NaHCO3 solution if necessary. 2. Place the amniocentesis. There are two ways to put in: 1 blind insertion method: under the guidance of the finger of the vaginal examination, slowly put into the amniocentesis cannula, enter the uterine mouth at a 30 degree angle into the sacral direction into the uterine mouth 1cm, take out the tube The core, insert the speculum and slightly back to the horizontal position, turn on the light source, you can see the lower part of the amniotic sac. If there is cervical mucus or blood secretion, use a grasping pliers to hold the cotton ball and wipe it clean. 2 direct insertion method: use the vaginal speculum to assist in dilating the vagina, and put it into the amniocenteoscope under direct vision. Not suitable for the crowd Inappropriate people: placenta previa, threatened premature delivery, temple first exposed, less than 37 weeks of gestation, the fetus is not yet mature.
