This study is designed to determine primarily if there is a difference in perceived pain in patients receiving urethral bulking with calcium hydroxylapatite using local lidocaine versus local lidocaine plus nitrous oxide gas. Patients will be randomized to a control group (local lidocaine plus room air) or a intervention group (local lidocaine plus 50% nitrous oxide/50% oxygen inhaled mixture). Their pain will be assessed immediately after the procedure, and their recollection of pain will also be assessed at their 2 week post-procedure visit. There are other secondary outcome measures as well; please see outcome measures section for full description.
Appropriate management of analgesia for proximal femoral fractures is a common problem in the emergency department (ED). Side effects from morphine usage such as nausea, vomiting, respiratory depression, sedation, and obstipation are especially pronounced in elderly. Fascia Iliaca Compartment Block (FICB) holds promise as a simple and safe, and effective alternative method to reduce pain. Local anaesthetic injected in the anatomic space underlying the fascia iliaca, spreads to block the nerves traversing it. This regional anaesthesia includes the femoral nerve. Previous studies in the ED showed promise but lacked blinding, involved low numbers of subjects, or did not use ultrasound localisation of the injection site. The latter is becoming common practice. In this randomised placebo controlled trial the FICB with ultrasound localisation of injection of levobupivacaïne will be compared to the FICB with placebo. It aims to prove that less morphine is used in the intervention group. Other research parameters are pain scores and minor adverse events related to morphine use.
The investigators are comparing an indwelling catheter with intermediate duration local anesthetic to a single shot peripheral nerve block with long acting a local anesthetic (Exparel).
The investigators will compare two physician behaviors for managing pain in patients with IBD: proactive vs. reactive. Both the proactive and reactive behavior/strategies are standard of care at the institution in which the study will be performed. The PROACTIVE strategy is an IBD-specific analgesic orderset (built into our EMR and approved by the institution's Pharmacy and Therapeutics committee), the REACTIVE strategy is a traditional "reactive" analgesic prescribing (prescribing medications only when patients have pain). The PROACTIVE IBD-specific analgesic orderset consists of medications which have evidence for use in IBD-related pain. This orderset is an educational guide, it does not force any order. The reactive prescribing habits could contain an array of pain medications depending on what the provider wants to prescribe. Aims: Aim 1: To assess whether there is a difference in pain scores or functional activity among hospitalized patients with IBD between reactive vs proactive physician behaviors. Aim 2: To assess whether there is a difference in inpatient opioid-prescribing between reactive vs proactive physician behaviors. Aim 3: To assess whether there is a difference in health care utilization, including length-of-stay and 30-day readmission, between reactive vs proactive physician behaviors.
This will be an open-label, multicenter, 30-day, unsupervised AUS among targeted (at-risk) adult and adolescent consumers designed to mimic an OTC-like environment. More specifically, "at-risk" consumers, as discussed with the FDA, will comprise elderly consumers (>65 years of age), consumers with an increased risk of gastrointestinal (GI) bleeding or cardiovascular (CV) adverse events, consumers who experience severe pain, low literacy subjects, and adolescents (12-17 years of age). The total number of subjects expected to enroll into the study is approximately 820. Sites will be pharmacies in diverse geographic locations around the US. Prospective adult subjects will be recruited via general population and targeted risk condition advertising (although participants will not be informed as to specific health conditions for which they are being recruited), while adolescents will be recruited using targeted, outbound pre-recruiting telephone calls. Subjects (or the parents/guardians of prospective adolescent subjects) responding to the advertisements or recruitment calls will be initially screened by telephone, and eligibility will subsequently be verified in-person at the pharmacy site.
The purpose of this project is to quantify normal and abnormal skin blood flow regionally in different areas of the body(face, extremities, over burns and wounds) at baseline and over time in response to treatment or environmental changes, such as temperature, light and pressure.
Significant pain is a common condition in dying patients. Continuous subcutaneous infusion (CSCI) of opioids is the cornerstone in treatment of pain in this last phase of life. Although morphine is the most frequent used opioid in this respect, burdensome adverse effects, like delirium and allodynia/hyperalgesia, can occur in dying patients, due to accumulation of morphine metabolites in decreasing renal function. Oxycodone seems preferable in this situation, as central effects of circulating metabolites of oxycodone are negligible. However, studies of sufficient quality investigating the clinical effect of this hypothesis are lacking at the moment. This study investigates whether there is a difference in occurrence of delirium and allodynia/hyperalgesia between oxycodone and morphine. Residents of hospices and somatic or psychogeriatric (PG) wards of nursing homes in the Netherlands, who are eligible for start of CSCI of an opioid for the treatment of pain in the terminal phase of life, are randomly assigned to one of two groups. One group receives CSCI of oxycodone and the other group CSCI of morphine. 117 patients per group are needed. Occurrence of delirium and allodynia/hyperalgesia is assessed three times a week until death of the participant. Quality of dying, as perceived by the patient's relatives, is assessed in an interview with a relative after death.
Recently, the uses of peripheral axial blocks that deliver local anesthetic into the transversus abdominis fascial plane have become popular for operations that involve incision(s) of the abdominal wall. Thus, the Transversus Abdominis plane (TAP) block has been shown to reduce perioperative opioid use in elective abdominal surgery, including open appendicectomy, laparotomy, and laparoscopic cholecystectomy. Currently, the Quadratus Lumborum block (QL block) is performed as one of the perioperative pain management procedures for all generations (pediatrics, pregnant, and adult) undergoing abdominal surgery. The local anesthetic injected via the approach of the posterior QL block ( QL 2 block ) can more easily extend beyond the TAP to the thoracic paravertebral space or the thoracolumbar plane, the posterior QL block entails a broader sensory-level analgesic and may generate analgesia from T7 to L1. Use of posterior QL block in laparoscopic prostatectomy has not been investigated before and it is the variant that will be discussed in our study.
Neuraxial labor analgesia is performed by the administration of a local anesthetic/opioid mixture in the epidural space. The delivery method is a combination of continuous infusion, provider-administered boluses and patient-administered boluses (patient controlled epidural analgesia [PCEA]) via epidural catheter. Pain during the first stage of labor is primarily due to lower uterine segment and cervical stretching. The pain signals enter the spinal cord through sensory nerves at the T10 through L1 dermatomes. Pain signals from the late first state and second stage of labor also arise from the vagina and perineum. These signals travel with the pudendal nerve and enter the spinal cord at S2-S4. Thus, the anesthetic solution administered through the lumbar epidural catheter must spread cephalad in the epidural space to reach the T10 nerve roots and spinal cord, and must spread caudad to reach the caudal nerve roots in the epidural space. The optimal method for maintaining labor analgesia is unknown. Several studies have demonstrated that PIEB, in combination with PCEA, provide superior maintenance of labor analgesia (less need and longer time to provider intervention, lower local anesthetic consumption, less motor block, and improved patient satisfaction scores) than maintenance with a continuous infusion with PCEA.The mechanism for this difference is not known; however, one suggested mechanism is improved spread of the local anesthetic within the epidural space. Kaynar et al. injected methylene blue dye through a multi-orifice catheter using either a continuous infusion or intermittent bolus and the area of diffusion was measured on a piece of paper. The authors found that intermittent boluses were associated with a greater surface area of diffusion than continuous infusion. In a cadaver study, dye was injected into the lumbar epidural space, and cryomicrotome sections were taken.Dye flowed in rivulets through small channels in the epidural space, as opposed to moving as a unified front. The authors found dye injected at high pressures had more uniform spread through the epidural space, supporting the concept of intermittent epidural injection providing superior analgesia. Epidural infusion pumps capable of delivering PIEB of local anesthetic with PCEA have become commercially available and many studies have attempted to assess the optimal parameter settings (including volume of programmed bolus, bolus interval, rate of bolus administration) to provide superior labor analgesia. Recently we completed a double-blinded randomized control trial evaluating two bolus delivery rates, hypothesizing that those patients randomized to receive higher bolus delivery rates would have improved labor analgesia. However, no difference was found between groups.What is more, both groups had a mean cephalad sensory level to cold of T6. This sensory level is higher than the traditional goal of T10 (upper dermatome level of uterine innervation), but despite the adequate sensory level, a large number of patients required supplemental physician-delivered boluses of local anesthetic during labor. Forty percent of the women in the high-rate group and 36% of the low-rate group required a manual re-dose during labor. This suggests that either a higher volume, or higher concentration of local anesthetic (i.e., higher dose) is needed to maintain adequate labor analgesia. Traditionally higher concentration local anesthetic solutions have been associated with increased motor blockade leading to a higher incidence of instrumental vaginal delivery. Several local anesthetic solutions with varying drug concentrations are available for labor analgesia and are used clinically in the United States. We plan to perform a randomized, controlled, double-blind study to test the hypothesis that patients whose labor analgesia is maintained using PIEB with low-volume bolus (6.25 mL) of a higher local anesthetic concentration solution (0.1% bupivacaine with fentanyl 2.0 mcg/mL) will require less supplemental analgesia (manual provider re-doses) than patients whose PIEB is delivered with a high-volume bolus (10 mL) of lower density local anesthetic solution (0.0625% bupivacaine with fentanyl 2.0 mcg/mL). The aim of this study is to evaluate the association between bolus volume and concentration of local anesthetic during maintenance of labor analgesia with programmed intermittent epidural bolus (PIEB) analgesia. The hypothesis of this study is: patients whose labor analgesia is maintained using PIEB with low-volume bolus (6.25 mL) of higher local anesthetic concentration solution (0.1% bupivacaine with fentanyl 2.0 mcg/mL) will have a longer duration of adequate analgesia (time to first manual re-dose request) than patients whose PIEB is delivered with a high-volume bolus (10 mL) of lower concentration local anesthetic solution (0.0625% bupivacaine with fentanyl 2.0 mcg/mL).
