Active clinical trials for "Abdominal Pain"

The goal of this randomised controlled trial is to study the (cost-)effectiveness of home-based hypnotherapy by self-exercises in children with functional abdominal pain (FAP) or irritable bowel syndrome (IBS) in primary care. The main questions it aims to answer are: What is the effect of home-based hypnotherapy by self-exercises on adequate relief of abdominal pain and discomfort in addition to care as usual of general practitioners (GPs), compared to care as usual of GPs alone in children with FAP or IBS? What is the effect of home-based hypnotherapy by self-exercises in addition to care as usual by GPs compared to care as usual of GPs alone in children with FAP or IBS on: Frequency and intensity of abdominal pain and discomfort Pain severity Daily functioning and impact Anxiety and depression Pain beliefs Sleep disturbances School absence Use of health care services, including GP visits and referrals to secondary care Costs (healthcare and societal perspective) Participants in the intervention group will receive home-based hypnotherapy 5 times a week for approximately 15-20 minutes a day during 3 months in addition to care as usual by their GP according to the Dutch society of GPs' guideline for children with abdominal pain. Participants in the control group will receive care as usual by their GP according to the Dutch society of GPs' guideline for children with abdominal pain.

Previous studies have confirmed that limb pain caused by oxaliplatin chemotherapy is related to spinal cord central sensitization - induced hyperalgesia through oxaliplatin activating spinal cord NMDA receptor(N-methyl-D-aspartic acid receptor). The investigators speculate that this may be the same as the mechanism of severe abdominal pain caused by HAIC(Hepatic Artery Infusion Chemotherapy) during oxaliplatin infusion. The analgesic effect of Esketamine is mainly related to its inhibition of NMDA receptor in spinal cord. Therefore, this study hypothesized that Esketamine can inhibit the sensitization of spinal cord center by inhibiting NMDA receptor, so as to alleviate severe abdominal pain during HAIC perfusion, and reduce abdominal pain caused by ischemia and inflammation by TACE(transcatheter arterial chemoembolization) by improving organ perfusion and anti-inflammatory effect, Therefore, it is expected that Esketamine can better alleviate acute severe abdominal pain caused by TACE-HAIC (transcatheter arterial chemoembolization combined with Hepatic Artery Infusion Chemotherapy )treatment than sufentanil, decrease the dosage of opioids, and reduce the incidence and degree of chronic abdominal pain after treatment.

The NSS-2 BRIDGE® device (NSS stands for Neuro-Stimulation System) is a disposable device that stimulates the branches of cranial nerves and of the superficial cervical plexus innervating the ear. Because the stimulation of the nerves of the ear by the NSS-2 BRIDGE® device (NBD®) has been shown to modulate pain pathways in rodents, decrease abdominal pain in adolescents with inflammatory bile syndrome and due to the results of our preliminary pilot study, the investigators hypothesized that this technique may also be effective in reducing the requirement for postoperative opioids and provide a non-pharmacological alternative to perioperative opioid use. To establish the role that the stimulation of the nerves of the ear may have in reducing postoperative opioid requirement, the investigators are proposing to conduct a randomized, placebo controlled study in patients undergoing open abdominal or pelvic surgery requiring at least 5 days of hospitalization. Subjects who have signed an informed consent will be randomized in 2 groups (active NBD® group or inactive NBD® group). Furthermore, since preoperative and postoperative mood disorders have been shown to increase postoperative pain levels and opioid requirement by up to 50%, the investigators further hypothesize that the stimulation of the ear nerves by the NSS-2 BRIDGE® effects may be in part mediated by a reduction of the level of anxiety, depression and catastrophizing as assessed using validated questionnaires.

Intravenous lidocaine will be given at a dose of 2 mg/kg intravenously to patients in the emergency department with a diagnosis of acute abdominal pain. Its efficacy will be compared to 1 mg of intravenous hydromorphone, with a primary endpoint of mean improvement of pain at 90 minutes.

This is a 12-month, parallel treatment, Phase 3, double-blind, randomized, placebo controlled study to evaluate the effect of venglustat on neuropathic and abdominal pain symptoms of Fabry disease in adult participants with Fabry disease who are treatment-naïve or untreated for at least 6 months. Study visits will take place approximately every 3 months. The double-blind period will be followed by an open-label extension (OLE) during which participants who have completed the double-blind period will be treated with venglustat for up to an additional 12 months.

The purpose of the trial is to identify the "most simple non-inferior of three different methods", placebo, laparoscopic assisted transverse abdominal plane block (L-TAP) and ultrasound guided TAP block (US-TAP), using postoperative opioid consumption as a measure of efficacy in patients undergoing elective minimally invasive colon surgery in an ERAS setting. Postoperative pain scores and length of stay (LOS) will also be measured. The simplicity of the three methods is ranked as: 1) placebo, 2) L-TAP and 3) US-TAP.

The investigators propose to conduct a dose-escalation trial of an FDA-approved antiepileptic drug, lacosamide, added to opioid therapy in patients with chronic abdominal pain from chronic pancreatitis (CP). This pilot trial will test the feasibility of the study design and provide reassurance regarding the tolerability and safety of lacosamide used concomitantly with opioids in this patient population to reduce the condition known clinically as opioid-induced hyperalgesia (OIH).

The purpose of this pilot study is to examine the feasibility and preliminary efficacy of Empowered Relief for Youth with chronic pain (ER-Y). ER-Y is a single-session pain management class for youth focused on pain science education and teaching self-regulatory skills for pain management based on the evidence-based adult ER class. Feasibility and acceptability of ER-Y will be assessed post-class. Preliminary efficacy will be assessed by administering surveys at baseline, 4-weeks, 8-weeks, and 12-weeks post class.

Pain is the main complication after TACE(Transcatheter Arterial Chemoembolization) for hepatocellular carcinoma, and its pathogenesis is not clear.The pain may be related to partial liver tissue swelling after blocking the tumor blood supply artery embolization agent, transient hepatic swelling causing tension or strain on the liver capsule, and chemical irritation by the anticancer drug-Lipiodol mixture,the inadvertent embolization of normal organs and individual sensitivity to pain. Ketamine produces anesthetic and analgesic effects mainly by inhibiting NMDA receptor(N-methyl-D-aspartic acid receptor), and previous studies have shown that low concentrations of ketamine have obvious analgesic effects. Not only that, ketamine also produces analgesic effects by inhibiting opioid receptors via G-protein coupling. In addition, ketamine can bind to monoaminergic receptors in the central and peripheral nervous system, showing an anticholinergic effect and producing an antispasmodic effect. Ketamine also inhibits inflammatory pain by reducing nitric oxide production by inhibiting nitric oxide synthase. Esketamine is about three to four times more potent than ketamine. Therefore,esketamine requires a lower dose, about half the dose of ketamine, to produce anesthetic and analgesic effects, with fewer side effects.

Cesareans are a frequent procedure in obstetrics and 15.4% (95% CI, 9.9-20.9%) of women with cesareans still have pain at 3 months after delivery. Currently, self-massage of the scar is recommended to them. Post-cesarean pain is associated with psychological disorders (including, e.g., anxiety, depression). Tecar therapy could improve the healing and pain associated with cesareans and therefore improve women's quality of life and their satisfaction. Objectives: The principal objective is to study the analgesic efficacy of tecar therapy for postoperative scar pain and/or discomfort at 3 month after cesarean delivery, by comparing it with sham tecar therapy. A randomized clinical trial with 2 parallel arms and single blinding, to study the efficacy of this medical device for therapeutic purposes. In both groups (randomization stratified as a first cesarean or repeat cesarean), the women will have the standard recommended treatment - manual self-massage of the scar. Women's instruction in this self-massage will be structured and identical for both groups, including the provision of an informational document describing how to perform this massage. The training will be provided immediately after randomization. Description of the experimental group These women will receive Tecar through Winback® technology [CE medical 1984, Norma 60601-2, ISO9001, ISO13485. Class IIa medical device, CET (capacitative mode) 400 VA and RET (resistant mode) 100 Watts, weight 4 Kg)]. Each session will last for 20 minutes, and each individual will have 3 sessions over a period of 3 weeks. Description of the control group ("sham treatment") The women will follow the same study design as the experimental group with activation of the portable placebo device identical to the active medical. Each session will last for 20 minutes, and each individual will have 3 sessions over a 3-week period. Principal endpoint: Visual analogic scale (VAS) for pain and/or discomfort at 3 months after delivery partum (with a ruler scored from 0 for no pain to 10 for the worst pain imaginable). Succinct description of the products: "Tecar" is an acronym for a type of therapy (transfer electrical capacitive and resistive). The Winback® is a portable, easy-to-handle noninvasive regenerator. This study will use only the instrumental mode and 4-cm electrodes. During each session, this electrode will be moved over the entire scar. We will use the following 3 modes: capacitive (CET), CET Dynamic, and resistant (RET). These allow us to standardize the treatment without taking into account either the thickness of the abdominal wall or the woman's morphology. Each session will take 20 minutes (CET for 4 min, CET Dynamic 6 min, RET 6 min and CET 4 min). The intensity of CET and RET will be adapted to each woman and the diathermy chosen according to the woman's threshold of comfort, to be determined by her at each session, in the experimental group. There will be 1 session a week for 3 weeks. Study plan and procedures: The eligible women will be identified by the physicians in both of the obstetrics departments participating in this study. The women will receive oral information as well as written information. If they are interested, they will be offered an inclusion visit, normally scheduled for one week later. After a second verification of the eligibility criteria at this inclusion meeting, reading the information form and signing the consent, they will be randomized into one of the two groups by random drawing. Each woman will have 3 sessions (1 session a week for 20 min for 3 consecutive weeks): active treatment by tecar therapy or sham/placebo tecar therapy. They will receive self-administered questionnaires at 3 and 6 months after delivery to be completed and returned.
