NCT ID: NCT04888858 Withdrawn - Analgesia Clinical Trials

Effect of Epidural Analgesia During Labor on Force of Maternal Push

Start date: November 2, 2020
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT04207138 Withdrawn - Labor Pain Clinical Trials

To Study the Association Among Labor Pain and Physical Parameters in Laboring Pregnant Women

Start date: April 14, 2020
Phase:
Study type: Observational

Analysis of monitored clinically parameters during the course of labor is a seldom studied area in Taiwan and worldwide. Important monitored parameters include, fetal heartbeat, uterine contractions, oxygen saturation and blood pressure, among others.1 During labor, uterine contractions can cause pain.3 This pain may be measured using a visual analogue scale (VAS).2 The pain from uterine contractions promotes the release of hormones including cortisol which can cause decreased or irregular contractions and possibly prolong labor.3 This study aims to study the association between monitored clinical parameters and pain in women in Taiwan during labor in order to increase the understanding to safe childbirth.

NCT ID: NCT03045705 Withdrawn - Labor Pain Clinical Trials

Evaluation of the Effect the Medical Team in the Delivery Room Has on Pain Management During Labor.

Start date: March 1, 2019
Phase: N/A
Study type: Interventional

In the current study the investigators wish to evaluate the effect the doctors and midwives in the delivery room have on the timing and modality of analgesia chosen by the participants. The participants will be randomly divided into 2 groups. Both groups will be advised of the different modalities of analgesia available during labor. One group will be managed in the delivery room the same as if not part of the study, meaning the doctors and midwives will treat the participants the way they usually do regarding analgesia. The second group of participants will not be asked by the doctors and midwives about analgesia at all but will be able to receive analgesia by a modality of choice at the timing of choice.

To assess the efficacy of epidural dexamethasone administration, compared to placebo, in reducing local anesthetics consumption during labor epidural analgesia in parturient women

NCT ID: NCT01636999 Withdrawn - Labor Pain Clinical Trials

Comparing Sedara to Butorphanol in Early Labor

Start date: September 2012
Phase: N/A
Study type: Interventional

Nitrous oxide (N2O) has been used for the treatment of labor pains for over 150 years. The longevity of its use in clinical practice can be attributed to its excellent safety profile, ease of administration, and familiarity of use among health-care providers. Sedara is a self-administered 50% N2O, 50% oxygen gas mixture with pain relieving and anxiety reducing properties recently available for use in the United States (US) to treat various painful clnical situations, including labor pains. In the US, epidural or intravenous administration of narcotic medications is one of the most common and frequently requested treatments for patients experiencing labor pains. Although generally considered safe, complications are common with epidurals, including fetal distress, low blood pressure in the mother, respiratory distress, and headache. In our hospital system, the use of the synthetic intravenous painkiller, Butorphanol, is a mainstay of treatment for labor pains. It too can have undesirable side effects in the mother, including low blood pressure and breathing problems. Because Sedara has until recently been unavailable in the US, studies comparing its efficacy with other agents for labor pain have been confined to Europe, predominantly in the United Kingdom. Several studies have investigated the efficacy of Sedara versus inhalation and intravenous anesthetics in various countries. We have obtained several Sedara devices for use in the West Penn Allegheny Health System (WPAHS) Department of Anesthesiology and would like to examine its efficacy in our target population of women experiencing pain during early labor. Hypothesis - Sedara will provide equivalent or superior pain relief among term, adult parturients in early labor (less than 5cm cervical dilation) compared to intravenous butorphanol. Primary aim - Compare Sedara versus butorphanol in a single-blinded randomized trial with the main outcome measure being reduction in labor pains at various time intervals. Our findings may be significant in terms of improving safety and efficacy of pain relief among women experienceing labor pains. Given that Sedara has not been previously studied in the US, the results may influence current obstetrical and pain management practices.

NCT ID: NCT01243216 Withdrawn - Pregnancy Clinical Trials

Does Ultrasound of the Spine Improve Labor Epidurals/Spinal Anesthesia in Obstetric Patients?

NCT ID: NCT00871442 Withdrawn - Labor Pain Clinical Trials

Parturient Controlled Epidural Analgesia (PCEA) With or Without a Basal Infusion for Early Labor

Start date: May 2009
Phase: Phase 3
Study type: Interventional

Patient Controlled Epidural Analgesia is a widely used and effective means of adult pain management. However, Parturient Controlled Epidural Analgesia (PCEA) is a relatively new approach to pain control for the women in labor. With the recent acquisition of new PCEA technology at Baystate Medical Center it is now possible to make this patient controlled technology available on the Labor and Delivery unit. This study is designed to determine whether there is a difference in analgesia, side effects, or analgesic duration in patients who receive a bupivacaine and fentanyl PCEA for management of labor pain. The present study hypothesizes that an analgesic protocol that includes a basal infusion rate in addition to a bolus dose controlled by the patient will have a longer analgesic duration than a pump protocol that does not have a basal infusion added to a bolus dose controlled by the patient. Methods:The study population will consist of 100 adult obstetrical patients greater than 36 weeks gestation who request labor analgesia. Patients greater than 5 cm cervical dilation, patients who have received intravenous opioid agonists, or patients with a contraindication to fentanyl will be excluded. Patients with pre-eclampsia are also excluded. One of the following PCEA treatment protocols will be started in a randomized, double blind fashion.PCEA solution: Bupivacaine 0.0625% with fentanyl 2 mcg/ml Group 1: Basal Infusion: 0 ml/hr; Bolus 10 ml q 30min prn (10ml demand dose with 30min lockout) Group 2: Basal Infusion: 10 ml/h; Bolus 5 ml q 30min prn (5ml demand dose with 30min lockout) If the patient does not obtain relief within 30 minutes, the epidural catheter will be dosed with a local anesthetic and the study will be concluded. The patients without pain relief within 30 minutes are considered to have failed epidurals and are dropped from the study and the analysis. Following achievement of satisfactory analgesia, the patient will be evaluated every 30 minutes until they request additional analgesics. The study will "end" at this point, and the patient will be treated at the discretion of the anesthesiologist.
