Clinical Trials About "Abortion"

Trial of Immediate Versus Delayed Initiation of Transdermal Hormonal Contraception After Therapeutic Abortion

This is a randomized, controlled trial investigating whether immediate versus standard, “Sunday Start”, initiation of transdermal hormonal contraception (the patch) in post-abortion subjects can improve compliance and the continuation of contraception. Immediate initiation of the patch has been studied in women seeking contraception when they are not immediately post-abortion, and this “Quick Start” method has been shown to improve the continuation of the patch into a s...

Trial of Immediate Versus Delayed Initiation of Oral Contraceptive Pills After Abortion

This is a randomized, controlled trial investigating whether immediate versus standard, “Sunday Start”, initiation of oral contraceptive pills (OCPs) in post-abortion subjects can improve compliance and the continuation of contraception. Immediate initiation of OCPs has been studied in women seeking contraception when they are not immediately post-abortion, and this “Quick Start” method has been shown to improve the continuation of OCPs into a second pill pack. The pr...

Evaluation of of a Prefixed 50% N2O- 50%O2 Mixture in Legal Abortion Under Local Analgesia

To evaluate effectiveness of a prefixed 50% N2O- 50%O2 mixture in legal abortion under paracervical block.

Mifepristone Versus Laminaria Insertion for Cervical Preparation Prior to Surgical Abortion at 14-16 Weeks

Women who are requesting pregnancy termination at 14-16 weeks, who would normally have osmotic dilator insertion the day before their procedure, would be asked if they wanted to participate. Participants would be randomized to two groups: first, dilator insertion as usual, or second, mifepristone taken the day before the procedure.

Gestational Age is Underestimated by Menstrual Dating Compared to Ultrasound Dating in Those Undergoing Abortion up to 20 Weeks

Several large trials report gestational dating by last menstrual period (LMP) overestimates gestational age (GA) vs. ultrasound (US) by approximately one week. Previous studies examined only term pregnancies. The investigators hypothesize an opposite tendency in women seeking abortion. This is an observational study undertaken by chart review.

Propofol-butorphanol Anesthesia During Uterine Curettage

Uterine curettage is usually performed under the anesthesia of propofol-fentanyl or para-cervical block,of which generally has significant incidence of respiratory depression which increases the demand on intraoperative monitoring, or has unavoidable insufficient blockade which results in intraoperative suffering of pain. Butorphanol is an analgesic with combined effects on mu and kappa opioid receptors leading to a role as analgesia and sedation. The investigators hypothesized...
