Active clinical trials for "Agnosia"

Management of postoperative pain is critical in the pediatric patients, however, safe and effective analgesia for pediatric surgical patients remains a challenge. Preemptive analgesia is based on preventing a prolonged change in central nervous system function by blocking afferent input before the surgical stimulation may evoke central sensitization and aggravate amplification and prolongation of postoperative pain. However, the clinical efficacy of preemptive analgesia is still controversial. In this study, the investigators aim to assess the impact of preemptive epidural analgesia on postoperative pain in pediatric patients for corrective osteotomy of the lower extremities expecting severe postoperative pain.

In this study, the investigators will compare the analgesic effect of bupivacaine and bupivacaine-dexmetomedine after elective cesarean delivery by performing an bilateral TAP block, on the patients for whom the operation will be performed under general anesthesia.

* The objective of the study: to assess the impact of a proactive policy of offering EA at the start of labour as compared to a restrictive policy or care as usual. * Study design: It concerns a multicentre randomised open label trial. * Study population: Term nulliparous and multiparous women with a child in cephalic presentation, and without contraindications for vaginal labour or EA. * Intervention: Women will be allocated to the EA group or the care-as-usual group. In the EA group, women are given an EA as soon as they are in labour. In the care-as-usual (restrictive) group, women receive pain relief only on their explicit request.

In a prospective randomised study involving primiparous women in spontaneous uncomplicated labour with cervical dilatation > 7 cm, epidural analgesia will be given with an initial volume of 20 mL anaesthetic solution, followed by a standardised algorithm of top-up manual injections to achieve analgesia, then by a patient-controlled regimen with 5-mL self-administered boli in addition to a continuous infusion of 5 mL.hr-1. The anaesthetic solution will be levobupivacaine presented in 100-mL bags from the market, 0.0625%, or 0.125%, in which 10 mL (50 µg) of sufentanil will be added. The final concentrations will be 0.568 and 1.136 mg.mL-1 respectively, both with sufentanil 0.45 µg.mL-1. Parturients and midwifes assessing pain during labour will be blinded to the design

Introduction: Many interventions such as hypnosis, mindfulness meditation, conditioned pain modulation and placebos have been shown to effectively reduce pain both in the laboratory and in clinical settings. However, little is known about their neurophysiological mechanisms of action. Analgesia induced by these techniques is thought to be based on opioidergic and non-opioidergic mechanisms (potentially endocannabinoid mechanisms). Objective: Our main objective is to evaluate the effect of hypnosis, meditation, conditioned pain modulation and placebo on blood concentrations of endocannabinoids (anandamide, 2-arachidonylglycerol, N-palmitoyl-ethanolamine, N-oleoylethanolamide), endogenous opioids (β-endorphins, met / leu-enkephalins, and dynorphins) and norepinephrine in healthy adults. Methods: This study is based on a single-group pre-experimental research design in which two experimental sessions including hypnosis or meditation, conditioned pain modulation and placebo interventions will be completed by all participants. In order to have a better description of the sociodemographic and clinical characteristics of the sample, information will be collected by questionnaires or tests filled by participants at baseline, including: age, sex, language, culture, religion, salary, menstrual cycle of women, medication (if any), mood, anxiety, pain catastrophizing, mindfulness, hypnotic susceptibility, and DNA information. Outcome measures will be collected before, during and after each intervention. The primary outcome is plasma concentrations of endocannabinoids. Secondary measurements include plasma concentrations of endogenous opioids and norepinephrine; change in pain intensity during the thermal noxious stimuli; and autonomic nervous system variability (as measured by heart rate variability). Anticipated results: The investigators expect a positive relationship between the change in pain intensity (analgesia) induced by the interventions (hypnosis, meditation, conditioned pain modulation, and placebo) and the change (increase) in plasma concentrations of endocannabinoids, opioids, and norepinephrine in healthy adults. It is also believed that the interventions will influence heart rate variability. Moreover, it is expected that there will be a relationship between the efficiency of the analgesic intervention and some gene polymorphisms associated to pain modulation and endocannabinoids, opioids or norepinephrine in healthy individuals.

Percutaneous electrolysis is based on the application of a galvanic current through an acupuncture needle. The underlying mechanisms that explain the efficacy of this technique are not completely well understood. The objective is to delve into the neurophysiological analgesic effects of percutaneous electrolysis. Participants will be assigned to one of three intervention groups. The analgesic effects of the technique will be evaluated by means of variables related to endogenous pain modulation.

The goal of this prospective randomized study was to compare the efficacy of transversus abdominis plane block and transversalis fascia plane block for postoperative analgesia in patients undergoing elective cesarean section under spinal anesthesia. The main question[s] it aims to answer are: [Is transversalis fascia plane block more effective in postoperative analgesia? ] [Is there a difference between the duration of postoperative first analgesia requirement? ] Since the pain scores after the block at the end of the operation will be evaluated during the postoperative 24 hours, the participants will be asked to give a value between 0 and 10 in certain time periods.

In our study, It was aimed to determine the dose of morphine that provides the most effective analgesia with the least incidence of side effects in the postoperative period.

This study examines the brain activation associated with placebo pain reduction.

This study was designed to examine the analgesic and side effects of dexmedetomidine-morphine mixture for intravenous patient-controlled analgesia (PCA).
