Filter by:This is a randomized controlled trial comparing pre-admission administration of routine oral preoperative non-narcotic analgesics with the administration of these medications in the pre-anesthesia care unit per our standard practice. Patients will be screened, enrolled, consented, and randomized during the preoperative office encounter, typically occurring within the 30 days prior to surgery. Patients randomized to pre-admission administration (study group) will be provided with a prescription for a one-time dosing of routine oral non-narcotic analgesic medications to be filled at the Cleveland Clinic outpatient pharmacy. Both the study and the control groups will receive written pre-operative instructions. Those patients randomized to the standard practice of administration in the pre-anesthesia unit (control group) will be administered the same medications in the same doses by the nursing staff. Patients in both groups will undergo general anesthesia, orogastric tube placement, and minimally invasive hysterectomy (MIH). Post-operatively, patient pain will be assessed via NRS at standard intervals and treated with narcotics. Amount of total intravenous (IV) and oral (PO) narcotics given during PACU stay will be documented in the medication administration record (MAR) within the electronic medical record (EMR) and later converted into oral morphine equivalents (OME). Pain will be assessed via NRS on discharge and documented. Patients will be emailed on POD10 a survey to rate their satisfaction with their medication administration regimen on a 5-point Likert scale. Participants will also be asked to complete a thirteen-point surgical recovery scale (SRS) to evaluate their functional recovery from MIH. Patient participation will conclude after completion of the patient satisfaction survey and SRS. A maximum of 58 patients will be enrolled into the study, as we aim to randomize 26 patients to each arm.
The use of titrated drugs is at the base of a successful antalgic treatment in order to provide both an adequate relief and a satisfactory tolerability profile. These molecules, though, have a varying degree of efficacy in different subjects due to medical and genetic reasons. The latter are mainly represented by cytochrome (CYP) P450, in particular CYP2D6's polymorphisms are responsible for the diversified metabolism of analgesics used in chronic pain treatments. Four main types of enzymatic metabolism make up the population, each one defined by a different CYP2D6 allele: extensive metabolizers, ultra-rapid metabolizers, intermediate metabolizers and poor metabolizers. Moreover, regarding polytherapies, the analgesics' metabolism could be influenced by coadministration of other drugs, thus determining an inhibition or induction of the metabolic enzymes - known as phenocopying - and potentially also a change in the metabolic phenotype itself. The final outcome is the inconstancy of effectiveness and of the risk of developing side effects. The primary objective of this study is to define a genetic pattern for the gene CYP2D6 by assessing the incidence of poor or ultrarapid metabolizers in a population of chronic pain patients. This will also allow to observe phenocopying in the same population. Hence 100 patients diagnosed with chronic pain will be enrolled. The genetic pattern of the gene CYP2D6 of such patients will be examined by taking mouth samples. At the same time parametric tests for paired data to survey the correlations between phenotypical patterns and pharmacological therapies will be conducted.
The study investigates the analgesic effect of different auditory inputs. Employing a within-subject design, the study includes healthy participants that are exposed to thermal stimuli while listening to three different auditory inputs. By repeating this on separate test days, the involvement of bodily processes is investigated.
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.
Minor painful procedures are frequently performed on newborn infants and non-pharmacological analgesia is commonly used. As more than one analgesic method may be applied simultaneously in clinical practice, the relative contribution and efficacy of analgesic components still needs to be further elucidated. In the present study neonatal cortical brain response during four types of non-pharmacological analgesia (oral glucose, expressed breastmilk, maternal holding plus oral glucose, maternal holding plus breastfeeding) will be studied. The aim is to assess the differential effect of oral solutions (glucose, breastmilk), when given alone or in combination with maternal relationship (holding, breastfeeding). The study will test the hypothesis that the mother-infant relationship would improve the analgesic effect of oral solutions.
This prospective randomized clinical trial evaluates the effects of a monitor-guided opioid analgesia during general anesthesia. To date no standard-monitoring device exists to specifically reflect the analgesic component of general anesthesia. Quality and safety of general anesthesia are of major clinical importance and should be improved by limiting the opioid analgesic's dosage to the minimum amount needed. The study compares the effects of monitoring nociception during general anesthesia with different innovative techniques in comparison to routine clinical practice.
The study intends to evaluate the efficacy of Tapentadol against placebo as a preemptive analgesic in the management of post-operative pain in the patiens undergoing total knee arthroplasty. The primary objective is to evaluate th epain score in visual analogue scale at various time points within 24 hours post operarively

Adequate analgesia in thoracic surgery is essential to prevent severe postoperative complications, especially respiratory problems. Current knowledge about gender-related differences in pain states generally more frequent and intense pain and more demand for analgesics in women. Results about postsurgical pain in particular are very inconclusive. The investigators tried to find out if gender has an influence on postthoracotomy pain and analgesics requirement.
We hypothesize that the Rivanna Accuro or similar U/S device would reduce time to success of identifying epidural and/or intrathecal spaces as compared to conventional palpation method.
