  • Gabapentin to Reduce Opioid Use Postoperatively (GROUP) in Children

    open to eligible people ages up to 17 years

    The primary objective of this study is to determine if the peri and post operative use of gabapentin in children reduces the need for narcotics after thoracic surgery. We hypothesize that patients who are given gabapentin will need fewer morphine equivalents postoperatively than those who were not given gabapentin

  • Closed-Loop Deep Brain Stimulation for Refractory Chronic Pain

    open to eligible people ages 22-80

    Chronic pain affects 1 in 4 US adults, and many cases are resistant to almost any treatment. Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but traditional approaches target only brain regions involved in one aspect of the pain experience and provide continuous 24/7 brain stimulation which may lose effect over time. By developing new technology that targets multiple, complimentary brain regions in an adaptive fashion, the investigators will test a new therapy for chronic pain that has potential for better, more enduring analgesia.

  • Latinx Children and Surgery

    open to eligible people ages 2-7

    Over 60 million persons in the United States (US) identify themselves as Latinx and 25.6% are children under the age of 16. Surgical disparities for adults and children have been identified as a major problem in the US and can be experienced at multiple points along a patient's health care trajectory. Data from the investigator's center indicates that a substantial portion of Latinx children who undergo surgery experience high anxiety and postoperative pain as well as postoperative impairments in psychological and physical functioning as compared to White non-Latin children who undergo surgery. Recent growth in use of mobile devices provides us an opportunity to create low-cost mobile health (mHealth) behavioral interventions to reduce this disparity in surgical outcomes. In a previous National Institutes of Health (NIH) award, the principal investigator (PI) developed and tested an evidence based mHealth tailored intervention (WebTIPS) that aims to prepare and be a companion of a child and their family during a surgical event. WebTIPS aims to enhance the recovery of the child in several ways such as reducing anxiety and pain and is based on information provision, modeling, and teaching of coping skills. WebTIPS, however, was developed and validated with a population of primarily White non-Latinx English-speaking children and their parents. Unfortunately, it is well established that mHealth interventions are significantly less effective when used with specific ethnic minorities unless they underwent a process of cultural adaptation. Over the past 4-years, the investigators have established multiple academic and community collaborations, conducted extensive participatory research with Latinx stakeholders and used the heuristic framework and a modified ecological validity model to culturally adapt WebTIPS. The culturally adapted intervention is called L-WebTIPS. The overall aim of this application is to reduce surgical disparities in a population of Latinx children undergoing surgery. The first phase of this application (R61) includes web programming of L-WebTIPS, conduct formative evaluation and conduct feasibly randomized control trial (RCT) to test this intervention. The second phase (R33) includes a multi-center RCT which aims to determine the effectiveness of L-WebTIPS compared to attention control intervention in decreasing postoperative pain, opioids consumption and lowering anxiety in Latinx children undergoing outpatient surgery. Secondary aims of the R33 include examining the impact of L-WebTIPS on home-based clinical recovery parameters such as pain, analgesic requirements, new onset behavioral changes and return to normal daily activity in Latinx children undergoing outpatient surgery. The investigators also plan to determine if the use of L-WebTIPS reduces anxiety and improve experience among the parents of Latinx children undergoing surgery. Finally, the investigators plan to determine if the use of L-WebTIPS reduces anxiety and enhance experience among the parents of Latinx children undergoing surgery. The investigators submit that using a cultural adaption process for an existing validated intervention will accelerate the process of reducing surgical disparities and bringing an effective intervention to clinical settings and routine use.

  • Pain Injection Versus Epidural Anesthesia for Hip Surgery in Pediatric Patients With Cerebral Palsy

    open to eligible people ages up to 18 years

    Pain management in pediatric patients presents a difficult challenge. Unlike adults, pediatric patients often cannot communicate their pain management needs clearly. This is especially true in patients with cerebral palsy (CP), who often have concomitant developmental delay, intellectual disability and verbal limitations. Current literature indicates pain as a common experience for children with CP but has been understudied in this population. Moreover, inadequate post-operative pain control can result in negative physiologic and psychological complications and lead to poor surgical outcomes. Currently, perioperative pain management following orthopaedic procedures in pediatric patients follows traditional protocols that rely on the administration of opioid medications despite their known adverse side effects including nausea, vomiting, itching, constipation, urinary retention, confusion, and respiratory depression. Epidural anesthesia is a key modality in traditional pain management for pediatric patients with CP given its proven efficacy in decreasing pain and managing spasticity. Yet, administering epidural anesthesia in this patient population poses several risks including damage to preexisting intrathecal baclofen pumps, iatrogenic infection, and technically demanding insertion given high rates of concomitant neuromuscular scoliosis. Alternatively, multimodal analgesic injections theoretically offer an efficacious adjunct to traditional pain management protocols with a lower risk profile. Preliminary data from our study group's pilot randomized control trial comparing the safety and efficacy of a multimodal surgical site injection to placebo showed decreased pain scores and narcotic consumption postoperatively in this patient population. Based on these promising results, the objective of this randomized control trial is to evaluate the efficacy of a multimodal surgical site injection compared to epidural anesthesia for postoperative pain control following operative management of hip dysplasia in pediatric patients with CP.

  • Regional Blocks for Lateral Condyle Fractures

    open to eligible people ages 4-12

    The purpose of this study is to investigate the post-operative pain control in pediatric patients with closed lateral condyle fractures who undergo open reduction and percutaneous pinning. Patients will be randomized into one of two groups. Group 1 will receive an infraclavicular nerve block to the affected extremity by a fellowship trained pediatric anesthesiologist prior to surgery. Group 2 will undergo the Orthopaedic Institute of Children's (OIC) standard preoperative protocol. Post-operative pain management will be the same for both groups per standard protocol. Pain level will be assessed post-operatively using the Wong-Baker FACES scale and parents will be asked to fill out a questionnaire regarding their satisfaction with the surgery and pain control. Parents will also fill out a medication log until the patient no longer requires pain medication. All patients in both groups will receive standard oxycodone solution prescriptions post-operatively as per typical protocol. The duration of participation in the study is approximately 1 week and requires 2 visits (time of recruitment at surgery and 1st post-op visit). This study is being conducted in hopes of developing comprehensive pain management protocols to reduce opioid consumption after surgical fixations of displaced lateral condyle fractures if the study can show that patients are more satisfied and require less opioid medication when receiving preoperative regional anesthesia.

  • Supracondylar Post-Operative Pain Study

    open to eligible people ages 5-12

    The purpose of this study to investigate post-operative pain control in pediatric patients with closed supracondylar humerus fracture who undergo closed reduction and percutaneous pinning. Currently, it is standard of care that patients receive a narcotic prescription for post-operative pain control. All patients will initially be seen in our pediatric urgent care and recruited at the time of surgery. Patients will be randomized to receiving acetaminophen and ibuprofen or acetaminophen and oxycodone. Parents will not be blinded to the acetaminophen but both investigators, parents and the patients will be blinded to the study drug (ibuprofen or oxycodone). Pain level will be assessed using the Wong-Baker FACES scale and parents will be asked to fill out a questionnaire regarding their satisfaction with the surgery and pain control. Parents will also fill out a medication log until the patient no longer requires pain medication. The duration of participation in the study is approximately 1 week and requires 2 visits (time of recruitment at surgery to 1st post-op visit). This study is being conducted in hopes of reducing opioid prescription after surgical fixation of uncomplicated supracondylar humerus fractures if our study can show that patient's pain levels post-operatively and parent/patient satisfaction are unchanged or improved in the acetaminophen and ibuprofen arm.

  • Transcranial Magnetic Stimulation for Chronic Neuropathic Pain

    open to eligible people ages 18-80

    Chronic neuropathic pain is defined as pain caused by a lesion or disease of the somatosensory nervous system. It is highly prevalent, debilitating, and challenging to treat. Current available treatments have low efficacy, high side effect burden, and are prone to misuse and dependence. Emerging evidence suggests that the transition from acute to chronic neuropathic pain is associated with reorganization of central brain circuits involved in pain processing. Repetitive transcranial magnetic stimulation (rTMS) is a promising alternative treatment that uses focused magnetic pulses to non-invasively modulate brain activity, a strategy that can potentially circumvent the adverse effects of available treatments for pain. RTMS is FDA-approved for the treatment of major depressive disorder, obsessive-compulsive disorder, and migraine, and has been shown to reduce pain scores when applied to the contralateral motor cortex (M1). However, available studies of rTMS for chronic neuropathic pain typically show variable and often short-lived benefits, and many aspects of optimal treatment remain unknown, including ideal rTMS stimulation parameters, duration of treatment, and relationship to the underlying pain etiology. Here the investigators propose to evaluate the efficacy of high frequency rTMS to M1, the region with most evidence of benefit in chronic neuropathic pain, and to use functional magnetic resonance imaging (fMRI) to identify alternative rTMS targets for participants that do not respond to stimulation at M1. The central aim is to evaluate the pain relieving efficacy of multi-session high-frequency M1 TMS for pain. In secondary exploratory analyses, the investigator propose to investigate patient characteristic that are predictive of responsive to M1 rTMS and identify viable alternative stimulation targets in non-responders to M1 rTMS.

  • Weighted Blankets for Postsurgical Pain

    open to eligible people ages 18 years and up

    The strongest psychological predictor of persistent pain after surgery is anxiety before surgery. The weight of blanket a person uses overnight may alter both anxiety and pain levels. The proposed study will determine whether a heavier or lighter blanket alters presurgical anxiety or postsurgical pain in individuals undergoing a breast surgery. We will also study whether any blanket-induced changes in postsurgical pain are related to reductions in anxiety before surgery induced by the blanket. Finally, we will examine clinical and psychological factors that might explain differences in how surgical patients respond to blanket weight. This research will improve our understanding of whether blanket weight can alter anxiety before a surgery or pain after a surgery.

  • Comparing Perioperative Outcomes in Pain Control

    Sorry, in progress, not accepting new patients

    This project consists of a randomized controlled study design. Study candidates will include all patients 18 years or older, who were evaluated at UCSD and found to have an orthopaedic injury requiring surgery. Patients who consent to study participation will be randomized to receive either the multimodal pain management protocol or standard oral hydrocodone-acetaminophen for post-operative pain management. Data on opioid usage, pain control, and functional status will be collected for each participant. After 3 years of data collection, investigators will analyze this data to provide further insight in determining appropriateness of pain regimens that reduce the overall opioid consumption. Given the widespread opioid epidemic, it is imperative to develop alternative means to appropriately manage pain in orthopaedic surgery patients.

  • Methods for Recording Post Operative Pain

    Sorry, not yet accepting patients

    The purpose of the current study is to identify the optimal method of collection of pain intensity data. The study will compare three collection methods: a hand-written pain journal, a smartphone app, and a novel electronic pain recorder device. Patients will be randomly assigned to one of three methods and instructed to record their pain level as often as they like. The number of pain intensity recordings per day will then be compared across groups.

  • Optimal Management of Pain in Hospitalized Patients - Opioid Tolerant Populations.

    Sorry, currently not accepting new patients, but might later

    Pain is a symptom that drives hospital admissions, and pain management is required by most patients during their hospital stay. Further, the use of medications such as opioids can lead to upward-spiraling doses, especially among chronic pain patients whose resource utilization rates are high. Many initiatives aim to reduce the costs of these "high-resource utilizing" patients. One exciting aspect of improving the management of pain is that this may help prevent patients from ever becoming high-cost in the first place. The purpose of this study is to examine the impacts of an early and sustained intervention pathway, in comparison to the current standard of care, for the treatment of pain in opioid tolerant patients. It is hypothesized that patients randomized to the intervention pathway, in comparison to the control, will lead to decreased costs of care, a reduction in opioid usage within 3 and 6 months, and decrease in hospital readmission rates.

  • Patient-Titrated Automated Intermittent Boluses of Local Anesthetic vs. a Continuous Infusion Via a Perineural Catheter for Postoperative Analgesia

    Sorry, accepting new patients by invitation only

    This will be a randomized comparison of continuous local anesthetic infusion with patient controlled boluses (PCA) to patient-titratable automated boluses with patient controlled boluses (PCA) for both infraclavicular and popliteal-sciatic perineural catheters. The overall goal is to determine the relationship between method of local anesthetic administration (continuous with PCA vs. titratable intermittent dosing with PCA) for these two perineural catheter locations and the resulting pain control. The investigators hypothesize that, compared with a traditional fixed, continuous basal infusion initiated prior to discharge, perineural local anesthetic administered with titratable automated boluses at a lower dose and a 5-hour delay following discharge will (1) provide at least noninferior analgesia during the period that both techniques are functioning; and, (2) will result in a longer overall duration of administration [dual primary end points].

  • Ultrasound-Guided Percutaneous Cryoneurolysis to Treat Postoperative Pain After Mastectomy

    Sorry, accepting new patients by invitation only

    Breast cancer is the most common type of cancer in women. Removal of the breast, called "mastectomy", is performed either when there is cancer-or an increased risk of cancer-in the breast. This can result in a lot of pain during the months after surgery. Opioids-"narcotics"-are the most common pain control method provided to patients; but they frequently do not relieve enough pain, have undesirable side effects like vomiting and constipation, and are sometimes misused which can lead to addiction. Mastectomy also frequently results in long-term pain which can interfere with physical and emotional functioning; and the more pain patients have immediately after surgery, the greater the risk of developing long-term pain. Numbing the nerves with local anesthetic can decrease the amount of short- and long-term pain experienced by patients, but even the longest types of these nerve blocks last for hours or days, and not the 1-2 months of pain typically following mastectomy. So, there is reason to believe that if the nerve blocks could be extended so that they last longer than the pain from surgery, short- and long-term pain might be avoided completely without the need for opioids. A prolonged nerve block may be provided by freezing the nerve using a technique called "cryoneurolysis". With cryoneurolysis and ultrasound machines, a small needle-like "probe" may be placed through anesthetized skin and guided to the target nerve to allow freezing. The procedure takes about 5 minutes for each nerve, involves little discomfort, has no side effects, and cannot be misused or become addictive. After 2-3 months, the nerve returns to normal functioning. The investigators have completed a small study suggesting that a single cryoneurolysis treatment may provide potent pain relief after mastectomy. The ultimate objectives of the proposed research study are to determine if temporarily freezing the nerves that go to the breast will decrease short-term pain, opioid use, physical and emotional dysfunction, and long-term pain following mastectomy when added to current and customary postoperative analgesics. The current project is a pragmatic, multicenter, randomized, triple-masked (investigators, participants, statisticians), sham/placebo-controlled, parallel-arm, human-subjects, post-market clinical trial to determine if cryoneurolysis is an effective non-opioid treatment for pain following mastectomy.

  • Ultrasound-Guided Percutaneous Peripheral Nerve Stimulation: A Department of Defense Funded Pragmatic Clinical Trial

    Sorry, accepting new patients by invitation only

    Postoperative pain is usually treated with opioids that have undesirable and sometimes dangerous side effects (e.g., vomiting and respiratory depression)-and yet over 80% of patients still experience inadequate pain relief. A novel, non-pharmacologic analgesic technique-percutaneous peripheral nerve stimulation (PNS)- holds extraordinary potential to greatly reduce or obviate opioid requirements and concurrently improve analgesia following painful surgery. This technique involves inserting an insulated electric lead adjacent to a target nerve through a needle prior to surgery using ultrasound guidance. Following surgery, a tiny electric current is delivered to the nerve resulting in potent pain control without any cognitive or adverse systemic side effects whatsoever. The electrical pulse generator (stimulator) is so small it is simply affixed to the patient's skin. The leads are already cleared by the US Food and Drug Administration to treat acute (postoperative) pain for up to 60 days; and, since percutaneous PNS may be provided on an outpatient basis, the technique holds the promise of providing potent analgesia outlasting the pain of surgery-in other words, the possibility of a painless, opioid-free recovery following surgery. The current project is a multicenter, randomized, quadruple-masked, placebo/sham-controlled, parallel-arm pragmatic clinical trial to determine the effects of percutaneous PNS on postoperative analgesia and opioid requirements, as well as physical and emotional functioning, the development of chronic pain, and ongoing quality of life.
