The rabbit test became a widely used bioassay (animal-based test) to test for pregnancy. The term "rabbit test" was first recorded in 1949, and was the origin of a common euphemism, "the rabbit died", for a positive pregnancy test. [4] The phrase was, in fact, based on a common misconception about the test.
Pregnant women should not be given injections of the drug terbutaline for the prevention of preterm labor or for long-term (beyond 48–72 hours) management of preterm labor, and should not be given oral terbutaline for any type of prevention or treatment of preterm labor "due to the potential for serious maternal heart problems and death." [2] [3]
By comparison, in the same 4000 women, a screening test that has a 99% sensitivity and a 0.5% false positive rate would detect all 10 positives while telling 20 normal women that they are positive. Therefore, 30 women would undergo a confirmatory invasive procedure and 10 of them (33%) would be confirmed as positive and 20 would be told that ...
When prostaglandin E 2 (PGE 2) is given in excess, hyper-stimulation of the uterus occurs and immediate discontinuation of the drug usually results in resolution of toxic effects. [33] [4] If symptoms continue a beta adrenergic drug (e.g. terbutaline) can be used. [citation needed] There are many different dosage forms of PGE 2. The ...
The two primary methods are testing for the female pregnancy hormone (human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography. [1] Testing blood for hCG results in the earliest detection of pregnancy. [2] Almost all pregnant women will have a positive urine pregnancy test one week ...
Throughout history, there have been different animal-based tests with the aim of indicating the pregnancy status of women. [4] The most well known test is the Hogben test, prevalent from the 1940s to the 1960s, by using the underlying principle of hormones and its subsequent biological response in both sexes of certain frog species.
Uterine hyperstimulation or hypertonic uterine dysfunction is a potential complication of labor induction.This is displayed as Uterine tachysystole- the contraction frequency numbering more than five in a 10-minute time frame or as contractions exceeding more than two minutes in duration. [1]
Membrane sweeping may lead to more women spontaneously going into labor (and fewer women having labor induction) but it may make little difference to the risk of maternal or neonatal death, or to the number of women having c-sections or spontaneous vaginal births. There are also risks associated with membrane sweeping.
