114 Clinical Trials for Various Conditions
Studies indicate that up to 75% of women will experience pain sometime during their pregnancy. Recent recommendations by the FDA recommended that non-steroidal anti-inflammatory (NSAIDS) medications be avoided during pregnancy. This recommendation limits the pain medications available for use during pregnancy. Antidotal evidence suggests that the FDA cleared Soovu pulsed heat device may produce pain relief during pregnancy. This study tests the Soovu device's ability to provide pain relief during pregnancy and up to one month post-partum and may eventually offer a safe nondrug option to treat pregnancy related pain. This is an observational pilot study The primary objective and hypothesis of this study is that the use of the Soovu pain management device will produce a significant reduction of pain when comparing pre versus post treatment pain.
In this pilot prospective longitudinal observational study, women who are pregnant and who will be experiencing childbirth for the first time will be recruited at the third trimester and observed longitudinally for psychiatric and pain characteristics until 3 months postpartum. The primary outcome is postpartum depression, assessed by Edinburgh Postnatal Depression Scale (EPDS). Infants will also be observed for infant development characteristics over time. Women who choose to receive labor epidural analgesia will be observed, as well as women who choose to avoid labor epidural analgesia. At baseline, women will complete baseline surveys as well as a baseline pain sensitivity test (quantitative sensory testing, QST). During labor, they will complete an electronic pain diary delivered by a bedside mobile device. Three postpartum assessments will occur over 3 months to assess maternal depression, other psychosocial variables, and infant development.
The primary objective of this study is to compare the onset and duration of the initial dose of medications given through three different epidural (conventional epidural, combined spinal epidural and dural puncture epidural) techniques for labor pain relief. The secondary objective of this study is to compare the fetal effects of these three epidural labor analgesia techniques.
The purpose of this study is to see which dose of epidural neostigmine is the best additive to use with the numbing medication used in an epidural during labor.
The study aims to understand why labor is more painful for some women compared to others. The study will study whether a woman's baseline pain sensitivity, beta2 adrenergic receptor genotype is related to her pain in labor for the birth of a first child.
The purpose of this study is to explore the differences between the pain associated with epidural Tuohy needle insertion with prior administration of subcutaneous or intradermal lidocaine using two different pain assessment tools (numerical rate scale (NRS) and Critical-Care Pain Observation Tool (CPOT)) in parturient women requesting epidural analgesia for laboring pain. Subjects will go through the following study procedures: review of medical history prior to surgery. Subjects will be randomly assigned to one of the two study groups in a 1:1 ratio to one of the two different standard methods to administer lidocaine prior to epidural Tuohy needle insertion: intradermal or subcutaneous lidocaine administration. Prior to insertion of the Tuohy epidural needle, each patient will receive an injection of 3 mL 1% lidocaine either intradermally (Group Intradermal) or subcutaneously (Group Subcutaneous). A blinded observer (positioned in front of the patient and unable to see the procedure) will record baseline NRS scores, HR, and BP after the patient has been positioned for the epidural procedure and prior to the administration of lidocaine. During the procedure, the blinded observer will objectively record patient's vocal responses, facial expressions, bodily movements, and muscle tension (caused by pain reflex) using the CPOT and NRS scales during lidocaine administration and the first Tuohy needle insertion. After each injection, the blinded observer will record the corresponding heart rate. When the procedural anesthesiologist has exited the room, the blinded observer will then collect the patient's procedure satisfaction score from 0 (worst satisfaction) to 10 (most satisfaction) at the conclusion of the procedure. Likewise, the blinded observer will also collect the final post-procedure heart rate and blood pressure.
This randomized controlled trial aims to compare the effectiveness of nitrous oxide versus oxygen in facilitating the successful placement of a Foley balloon catheter for cervical ripening and induction of labor.
The aim of the study is to develop a device that can eliminate failed neuraxial placements in challenging patients.The study will attempt to improve safety and efficacy of neuraxial anesthesia with high precision real-time needle visualization through automated real-time needle guidance at the bedside with an experimental device (Accuro 3S). Investigators will verify the clinical workflow for utilizing the Accuro 3S during epidural and spinal procedures and validation of needle visualization while using the device as well as anatomical guidance provided by the device during spinal imaging.The underlying bone imaging enhancement algorithms were introduced in the commercially available FDA approved Accuro. The Accuro 3S will be used to establish needle insertion point and trajectory, after which the clinician will use standard of care methods to advance the needle such as the loss of resistance method.
The primary objective of our study is to use a biased coin up-down allocation methodology to estimate the dose of bupivacaine required after the lidocaine test dose to achieve initial effective comfort in 90% of patients (post test-dose ED90) via the epidural (DPE or EPL) technique in women undergoing labor induction or augmentation; the investigators hypothesize that the investigators will be able to determine the post test-dose ED90 of bupivacaine for each technique with adequate precision to inform the optimal doses to study in a subsequent randomized trial comparing the analgesic effects of DPE vs. EPL. The investigators also hypothesize that the post test-dose ED90 of bupivacaine is lower with a DPE technique than with a conventional epidural technique.
To estimate the dose of bupivacaine required to achieve initial effective comfort in 90% of patients (ED90) via the epidural (DPE or EPL) technique in women undergoing labor after receiving a lidocaine "test dose"
The primary purpose of this study is to determine if there are differences in block quality between the CSE and DPE techniques for labor analgesia in parturients in active labor. We hypothesize that when compared to the CSE technique, the DPE technique will significantly improve block quality in this population and require fewer "top-ups" and catheter replacements.
There are multiple factors that determine progress of normal vaginal delivery. Frequency, duration and strength of uterine contractions are important for progress throughout labor, and abdominal wall muscle contractions contribute to progress during the final stage. Epidural analgesia helps to alleviate the pain associated with uterine contractions, this however this comes at the expense of prolonging labor by reducing the strength of abdominal wall muscle contractions. The purpose of this prospective study is to quantify how much epidurals decrease the strength of abdominal wall contractions. Intraabdominal pressure will be used as surrogate to strength of abdominal wall contractions, and it will be measured via a foley catheter inserted into the urinary bladder as part of standard procedure for patients receiving labor epidurals. We will compare the change in intraabdominal pressure when patients perform forceful abdominal contractions (valsalva maneuvers) prior to and during epidural analgesia. This will lay the foundation for a future study in which we plan to compare the effects of different epidural analgesia types and concentrations on abdominal wall muscle contractions.

The goal of this study is to determine whether the use of sequential compression devices (lower limb compression) can reduce the rate of maternal hypotension after epidural, and therefore reduce the incidence of fetal heart tracing complications during labor.
The purpose of this study is to determine if non-invasive distracting devices (Virtual Reality headsets) are non-inferior to conventional therapy (nitrous oxide) for addressing maternal needs during labor who desire non-epidural pain relief.
Ultrasound is widely in uses for vascular, nerve block and sometimes neuraxial block. The purpose of the study is to evaluate the impact of a handheld ultrasound device on the time to complete labor epidural placement and success rate of epidural analgesia in parturients with a wide range of body mass indexes (BMIs). A handheld ultrasound device (Accuro, Rhivanna Medical, Charlottesville, VA) may eliminate the time for equipment setup due to its portability and instant power-up. In addition, it provides a simulated diagram to aid in identifying bone and lumbar spaces. These unique features may be helpful in laboring women with a particular BMI range. We aim to define the usefulness of guidance with a handheld ultrasound in completing labor epidural analgesia in various BMIs. The primary outcome: The time needed to complete epidural placements. Secondary outcomes: * The number of needle insertion attempts, * The rate of success measured by the need to replacements during the labor course for vaginal or cesarean delivery.
This study will compare the performance of a contraction monitor (tocometer) device developed by Fetal Life with standard tocometer devices. The study aims to test a uterine contraction monitor that can be applied by the patient to her abdomen and connected to her smart device to detect the frequency and duration of uterine contractions. Phase 1 will collect data for calibration of the monitor and for a noninferiority study comparing the Fetal Life uterine contraction monitor (tocometer) with standard tocometry devices. Phase 2 will be a feasibility study in which patients will position the monitor, connect to the corresponding Fetal Life app and measure their own uterine contraction activity. The study's hypothesis is that after calibration, the new monitor will reliably detect at least 95% of the number and duration of contractions detected by the standard monitor, and that the device will perform comparably whether applied by the patient or by research staff.
The aim of the study is to assess if there is a difference in ability to thread the epidural catheter from two different epidural pain management kits vendors
There have been studies reporting that combined spinal-epidural (CSE) with fentanyl and bupivacaine produce fetal bradycardia, (M.Kuczkowski, 2004) (Abrão K, 2009 ). It is unknown whether any differences in risk exist between fentanyl and bupivacaine when used as a part of the CSE procedure. Some authors have reported cases of parturients who developed uterine hyperactivity and fetal bradycardia after subarachnoid administration of fentanyl during labor. (D'Angelo \& Eisenach, 1997) (Friedlander JD, 1997). It has been suggested that uterine hypertonus, leading to non-reassuring fetal heart rate tracings, might be an etiologic factor in these situations. (Landau, 2002). We propose this study to test the hypothesis that administration of epidural fentanyl is associated with a lower incidence of fetal bradycardia compared to intrathecal fentanyl.
Color Flow Doppler (CFD) utilizes Doppler information obtained from signals sent to and received from a transducer. This information is color-encoded and then displayed as color on an overlay of the two-dimensional image. The color scale represents both speed and direction of flow within a discrete area of the image. CFD has been recently used to determine the position of the epidural catheter. However its role in labor epidural has yet to be defined. This study describes the use of CFD to confirm the position of the tip of the epidural needle in the context of labor analgesia. This study hypothesized that CFD is a feasible method for identifying proper epidural needle placement prior to epidural catheter advancement.
This will be a prospective study on labor characteristics, and obstetric and neonatal outcomes in women who accept and women who decline morphine as a form of pain management in labor. The study will also investigate patient satisfaction with this form of analgesia. The participants will be those who accept morphine and promethazine and those who decline morphine and promethazine for pain control.
The purpose of this study is to identify whether use of virtual reality devices can improve the pain management of women in labor and delivery. The investigators will perform a randomized controlled trial of patients in labor at Cedars-Sinai Medical Center.
This study is being done to investigate if there is more effective pain relief during the latter stages of labor and delivery when epidural fentanyl 100mcg is administered compared to epidural fentanyl 20mcg.
This study will compare and determine the most ideal local anesthetic (LA) solution to activate a labor epidural: lidocaine, bupivacaine, or a combination of bupivacaine plus lidocaine.
Data are lacking regarding the use of music and video games for the management of pain in labor. Pregnant women that are scheduled for labor induction with Foley bulb after 37 weeks will be approached for participation in the study. Patients will be randomized to a music/video games group and a non-music/video games group. Those randomized to group with music/video games will be given an iPod for those purposes.The primary outcome will be the time for patients to request pain medications after Foley bulb placement. The two groups will be compared for differences in pain outcomes.
Placement of labor epidurals is a very common daily practice in obstetrical anesthesia. Currently, these epidurals are placed based upon palpation of landmarks to determine midline and the correct spinal level for placement. Palpation of these landmarks can be difficult, however, particularly in morbidly obese patients who have significant amounts of soft tissue overlying them. This study seeks to use ultrasound guidance to examine the spine prior to epidural placement, and see what effects this has compared to palpation alone with respect to procedure time, number of attempts, success rate in the first attempt, failure rate, complication rate, patient anxiety levels, and patient satisfaction levels.
The aim of this prospective, doubled-blinded randomized study is to compare two modes of epidural analgesia delivery, programmed intermittent epidural boluses (PIEB) versus continuous epidural infusion (CEI) with patient controlled epidural analgesia (PCEA) dosing, for providing labor epidural analgesia. The primary outcome will be the volume of local anesthetic received through PCEA. Secondary outcomes will measure time to first PCEA bolus, labor pain scores, degree of motor blockade, mode of delivery, PCEA attempts and ratio of successful to unsuccessful attempts, frequency of hypotension, duration of first and second stages of labor and level of patient satisfaction. The investigator plans to enroll 120 nulliparous participants at 2-5 com cervical dilation, with 60 patients to each arm. The subject will be assigned to receive either delivery of epidural medication ropivacaine 0.1% with fentanyl 2mcg/mL with PIEB + PCEA dosing method or CEI + PCEA. Continuous data will be analyzed using the Kruskal-Wallis test or t-test as appropriate. Categorical data will be analyzed using Chi-square test or Fisher's exact test as appropriate.
The purpose of the proposed study is to evaluate the feasibility of using immersive Virtual Reality (VR) during labor. We will also explore whether VR distraction is helpful for reducing subjective pain during labor, even if this pain is severe or excruciating. We predict that VR is feasible in this setting and that VR distraction will reduce acute pain and anxiety during labor.
This research will explore the question of whether preincisional skin infiltration with bupivacaine 0.25% decreases postoperative pain after Cesarean delivery.
The purpose of this study is to see if an educational intervention provided to pregnant women in early labor has an effect on their decision to use epidural anesthesia for relief of labor pain. The study will also investigate differences between Hispanic and non-Hispanic white women in their attitudes and beliefs regarding epidurals in labor. Previous studies have shown that Hispanic women receive epidural anesthesia in labor much less frequently than their non-Hispanic white counterparts. The investigators hypothesize that the rate of epidural use will be higher in subjects who receive the educational intervention than in those who do not. Women who have been admitted to the OHSU labor and delivery unit will be screened for study eligibility. In order to minimize the influence of socioeconomic factors, only women receiving Medicaid will be enrolled. Other inclusion criteria include age of at least 18 years, having a fetus of at least 24 weeks gestational age, and being categorized as American Society of Anesthesiologist category 1 to 3. Exclusion criteria include any condition that either excludes or mandates neuraxial anesthesia. Midwife patients are also excluded from this study. Those who meet study criteria will be approached by a member of the study team and informed consent will be obtained. Subjects will be randomly assigned to receive an educational intervention about epidurals or no educational intervention. Hispanic and non-Hispanic subjects will be randomized separately, yielding four study groups (Hispanic - intervention; Hispanic - control; non-Hispanic - intervention, non-Hispanic - control). The investigators expect to enroll approximately 176 women, 44 in each group. All subjects will complete a survey in early labor and again 1 to 2 days postpartum that asks about common beliefs and misconceptions regarding epidurals. Subjects in the intervention group will receive an educational pamphlet and watch a video in their native language (spanish or english) about epidurals, and have an opportunity to ask questions. Study staff will collect limited information about the subject's labor and delivery from the electronic medical record.
