the aim of this study was to evaluate the effect of estradiol (e2), oxytocin (ot), relaxin (relaximol) injection and prostaglandin e1 (misoprostol) suppository on the cervix dilation, time of cervical dilation persistency and pregnancy rate of zandi ewes using artificial insemination. eighty 3-4 years old and 55±2.5 kg weight ewes were used for this study. in experiment 1, the ewes were assigne...

in sheep industry, pregnancy rate after artificial insemination (ai) declines due to the complex anatomy of the cervix in ewes, such that it might prevent effective intrauterine insemination. at estrus, cervical relaxation occurs to some degree in ewes, which is regulated by the changes in the levels of reproductive hormones. this study aimed to evaluate the effects of estradiol and intravenous...

introduction: despite wide use of hyoscine by midwives and doctors as an adjunct to labor, the obstetrics literature contains few references to the effect of this drug. this study was a double blinded, randomized controlled trial of primigravidas in iran to determine the effects of hyoscine intravenous injection on parturition (labor). methods:one hundred primigravidas in uncomplicated spontane...

BACKGROUND Cervical dilation using mechanical dilators is associated with various complications, such as uterine perforation, cervical laceration, infections and intraperitoneal hemorrhage. To achieve safe and painless cervical dilation, we constructed a new medical device to achieve confident mechanical cervical dilation: a continuous controllable balloon dilator (CCBD). METHODS Controlled p...

results there were significant differences between the groups in subjective labor pain scores (except vas 4) (p < 0.001). the duration of the phase one (3 cm dilatation to full dilatation) and phase two (full dilatation to birth) in the acupressure group was shorter than the control group (phase one, 225 min and 320 min, respectively; phase two, 15 min and 20 min, respectively; both p < 0.001)....

Background and Objective: Epidural analgesia (EA) has been used to relieve labor pain in many obstetric units, yet controversy persists about its effect on progress and outcome in labor. The purpose of the current study was to evaluate the effect of EA on the rate of cervical dilation and myometrial contractility. Methods: In a 6-month period, 36 women who received standardized EA were mat...

First-trimester surgical abortion is a common, safe procedure with a major complication rate of less than 1%. Cervical dilation before suction abortion is usually accomplished using tapered mechanical dilators. Risk factors for major complications in the first trimester include increasing gestational age and provider inexperience. Cervical priming before first-trimester surgical abortion has be...

OBJECTIVE To compare the efficacy and acceptability of buccal misoprostol or a synthetic osmotic cervical dilator for cervical preparation before same-day late first-trimester and early second-trimester surgical abortion. METHODS In this randomized, double-blind trial, we compared 400 micrograms of buccal misoprostol with one synthetic osmotic cervical dilator administered 3-4 hours before su...
