Midtrimester abortion by dilatation and evacuation versus intra-amniotic instillation of prostaglandin F2 alpha: a randomized clinical trial. 1980

D A Grimes, and J F Hulka, and M E McCutchen

To compare the safety and feasibility of midtrimester abortion by outpatient dilatation and evacuation (D-E) versus inpatient intra-amniotic instillation of prostaglandin F2 alpha (PGF2 alpha), we performed a randomized clinical trial with 100 subjects estimated to be 13 to 18 menstrual weeks pregnant. Subjects undergoing D-E abortion had significantly better compliance with the assigned treatment (100% vs. 88%, < 0.05) and less delay prior to abortion (mean 3.7 vs. 10.1 days, p < 0.001). Subjects receiving PGF2 alpha had a relative risk of sustaining a complication 5.7 times that of subjects undergoing D-E (95% confidence interval 2.1-15.3, p < 0.001). Subjects receiving PGF 2 alpha also had significantly higher rates of vomiting and diarrhea (p < 0.01). Midtrimester abortion by outpatient D-E appears to be more acceptable to women, faster, and safer than by instillation of PGF2 alpha.

A family of prostaglandins that includes three of the six naturally occurring prostaglandins. All naturally occurring PGF have an alpha configuration at the 9-carbon position. They stimulate uterine and bronchial smooth muscle and are often used as oxytocics.	PGF
D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random
D002986	Clinical Trials as Topic	Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries.	Clinical Trial as Topic

D005865	Gestational Age	The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.
