7 Clinical Trials for Various Conditions
The purpose of this study is to determine if lubricating gel affects patients' perception of discomfort during speculum insertion, as compared to water.
This prospective randomized controlled study examines whether the type of glove used (sterile vs clean) for cervical examination to assess progression in labor impacts the rates of intrapartum and/or postpartum infection in patients during labor or induction of labor at term.
Trial to compare the interexaminer agreement between two cervical dilation examinations conducted by Labor and Delivery physicians when using standard methods versus DilaCheck device.
Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is an emerging field in minimally invasive surgery. International consensus-based statement was recently published to help guide the basis for adopting vNOTES into clinical practice, including regarding patient selection. It was agreed that women with potential adhesions are not appropriate candidates for vNOTES approach including women with suspected adhesions due to history of severe pelvic inflammatory disease (PID) or endometriosis. However, as some pelvic infections might be asymptomatic, pre-operation imaging might be beneficial to complete improved selection of patients. Moreover, women with previous severe PID or endometriosis might still have favorable pelvic to perform the vNOTES approach. Therefore, we aim to compare pre-operation ultrasound evaluation to operative characteristics and outcomes in women undergoing VNOTES approach surgery.
This new invention addresses the inadequate and incomplete visualization of the cervix in patients with excessive vaginal tissue. In general these patients are obese, or are multiparous with a history of multiple vaginal deliveries. A vaginal speculum is a vital medical instrument that allows a health care provider to visualize the interior aspects of the vagina, as well as the distal portion of the uterus, the cervix. It is composed of 2 blades assembled together and held by a handle. The blades and the handle form a 90 degree-angle. As the user holds the handle, a lever attached to the top blade allows it to open away from the inferior blade. When the instrument is inserted into the vagina, the two blades are separated in order to keep the anterior and posterior vaginal walls apart. In that position, the cervix and the walls of the vagina can be seen if the patient does not have an excess of loose vaginal tissue. However, in patients with excessive tissue, the sidewalls of the vagina simply collapse toward the midline between the blades because of the fact that no part of the speculum is in direct contact with the lateral walls of the vagina. This collapse prevents the complete and crucial visualization of the cervix for purposes of cervical cultures, pap smears, visual assessment of ruptured membranes, visual assessment of the degree of dilation, biopsies, and other procedures requiring access to the cervix or the uterus. When clinicians face this dilemma, they may try the largest speculum available, and will open it as wide as possible in order to keep the lateral walls apart. Most often, they have to improvise by cutting the tip of a condom, or the thumb off a glove, or they use a sterile lateral-wall retractor. These other creative solutions can take several minutes of precious times and may still result in an inadequate visualization and suboptimal access. A vaginal speculum sheath for retaining vaginal tissue in a lateral direction conforms to a pair of blades that are movable between an opened position and a closed position. The blades in the closed position are adapted for insertion into a vagina, and in the open position, they allow dilating the vagina in order to provide access to the cervix. This new design includes a flexible, transparent polyurethane sleeve structure that extends between the blades when the speculum is opened. The stretched sheath is adapted to retain the lateral walls of the vagina in the open position. The elastic sleeve is designed to remain in a collapsed configuration when the blades are in a closed position to avoid interfering with insertion or withdrawal of the speculum \[Reference: U.S. patent 6432048 (2002-8-13)\]. Polyurethane material is FDA approved for vaginal use. The purpose of this study is to compare standard of care speculum vs. sheathed speculum in the examination of patients with collapsing vaginal sidewalls during a gynecological speculum exam. The primary hypothesis testing for this study will be to compare the standard of care speculum exam to a sheathed speculum exam in a prospective, randomized clinical trial.
Pessaries are effective non-surgical devices for reduction of prolapse. However, use of pessaries are limited in some women due to patient discomfort. While lidocaine can be used to improve pessary checks, its use may be limited due to supply chain shortages, lack of insurance coverage, and optimization of resource utilization. More techniques to improve pessary examination comfort are needed. Perineal massage prior to delivery and at the time of active labor has been noted to reduce perineal trauma and perineal discomfort, theoretically by desensitizing the nerve endings in the skin, broadening the vaginal opening, and increasing elasticity of the perineal tissue. Since most discomfort with pessary checks is during removal and insertion through the vaginal introitus, perineal massage may be a beneficial technique that women could potentially learn to improve comfort with pessary checks. The objective of this study is to examine the effectiveness of perineal massage prior to pessary check in improving comfort of pessary checks for patients using a cross-over randomized controlled trial. Patients who follow up for pessary checks with the division of Urogynecology at UNC will be approached about participating in this study. The study will involve two clinical visits. At the first visit, the patient will be randomized to 2 minutes of perineal massage with water based gel of the external perineum and sides of the vaginal vestibule, as well as internal massage with the thumb, gliding from 4 to 8 o'clock, then tissue stretching technique with one intracavitary finger and other external finger at the 4 o'clock and 8 o'clock positions three times; versus application of gel to the internal vagina and external vagina without massage. Providers will be blinded to randomization and proceed with pessary check as per normal clinical protocols. Patients will rate self-reported pain before, during pessary check, and after the pessary check on a VAS scale; and rate whether they would prefer to repeat this method at future visits via Likert scale. Healthcare professionals will also rate perceived patient pain on VAS scale; ease of pessary removal; and note any perineal or introital laceration or abrasion that may occur during the pessary fitting. At the following visit, patients will be assigned to the group to which they were not initially randomized. Patients and healthcare professionals will again rate pain as described above. Patients will also rank preference for perineal massage using PGI-I.
The purpose of this study is to estimate if a novel sheathed speculum provides improved visualization of the cervix compared to a standard ("non sheathed") speculum, and to estimate if the sheathed speculum causes less discomfort during the examination.
