6 Clinical Trials for Various Conditions
The purpose of the proposed study is to examine the relationship between cerclage suture material of Ethibond and Prolene and its effect on the vaginal microbiome in a prospective randomized control trial. Ethibond is another commonly used suture material for performing cervical cerclage that shares some characteristics with previously studied suture materials. It is braided like the Mersilene, but thinner like the monofilament Prolene. The investigators will study whether Ethibond causes the vaginal microbiome to be adversely affected like Mersilene or whether there is a healthy microbiome like Prolene. This study will allow the investigators to determine whether it is advisable to continue to use Ethibond for cervical cerclage in clinical practice, or whether obstetricians should avoid its use as now done with Mersilene.
This study aims to compare the effect of chloroprocaine vs. bupivacaine on duration of motor block and duration until meeting discharge criteria in patients undergoing cervical cerclage. The hypothesis is that chloroprocaine will result in faster resolution of motor block.
The goal of this Phase I clinical trial is to generate proof-of-concept data to demonstrate that a cervical cup in combination with vacuum application will create negative pressure on uterine cervical tissue, thereby creating immediate cervical stiffness in order to prevent cervical ripening that is associated with spontaneous preterm birth. Aim #1: Conduct a Phase I clinical study. 1A: Evaluate the ability of a cervical cup to improve cervical tissue physiology of uterine cervices in vivo for nonpregnant women. 1B: Evaluate the ability of a cervical cup to be safely placed and removed on uterine cervices in vivo for nonpregnant women.
Azithromycin is an antibiotic that is effective against bacteria that been associated with preterm birth (PTB). The purpose of this study is to evaluate if the addition of azithromycin prior to exam indicated cerclage prolongs gestation. A cerclage is a suture placed in the cervix to prolong gestation.
This study aims to determine whether or not spinal anesthesia with the local anesthetic drug, chloroprocaine, wears off faster than the local anesthetic drug, bupivacaine, and results in faster discharge from the post-anesthesia care unit after surgery.
The primary objective of this study, is to determine the effect of a Cup pessary, a device that is currently readily available in the USA and similar in design to the Arabin pessary, on the incidence of delivery prior to 37 weeks in women with a history of prior spontaneous birth (before 37 weeks) and incidentally found to have a cervix less than 25 mm in length prior to 23 weeks.
