Ketamine as a Supplement to Local Anesthesia for Minor Procedures
Description

This trial is a double-blind randomized controlled clinical trial of adults and children (ages 7 to less than 70 years). Patients who present to the ED and who undergo minor bedside procedures that require local anesthesia will be divided into two groups: The first group will be treated with 0.7 mg/kg intranasal ketamine as well as standard local anesthesia for the procedure (treatment cohort). The second group will be treated with a volume-based dose of intranasal saline solution as well as standard local anesthesia for the procedure (control cohort). The primary aim is to assess whether patients in the treatment cohort report lower pain scores on the Numerical Rating Scale (NRS-100) when compared to patients in the control cohort. For adult patients, a secondary aim is to compare agitation between the two cohorts using the Richmond Agitation Sedation Scale (RASS) and, for pediatric patients, a secondary aim is to compare alertness between the two cohorts using the University of Michigan Sedation Scale (UMSS). Results obtained from specific procedures will be analyzed on a spectrum of complexity and general length of recovery time. Scientific achievements may include finding a safe and effective way to reduce pain and discomfort during minor procedures in the Emergency Department. Additionally, it would provide opportunities for more research on sub-dissociative doses of ketamine during minor procedures: a topic in which there is still a gap in the published research

Distraction for Reduction of Pain Associated With Venipuncture in the Pediatric Post-Transplant Population
Description

Children with chronic diseases, particularly those who have received transplantation (e.g. cardiac, renal, or liver) are a population who undergo frequent painful procedures, such as venipuncture multiple times per week. There is currently no standard of care for pain reduction during venipuncture for pediatric patients having blood drawn in phlebotomy as an outpatient. The study aims to determine the efficacy of distraction in reducing procedural pain and distress associated with venipuncture in pediatric post-transplant patients.

The Effects of Endotracheal Suctioning on Pain and Serum Markers
Description

The goal of this experimental study is to understand if endotracheal tube (ETT) suctioning increases pain and causes stress on the body in intubated adult ICU patients. These patients are already on ventilators, which means they need suctioning to keep their airways clear, but this procedure may be uncomfortable and cause stress. The main questions this study aims to answer are: Does ETT suctioning raise pain levels as measured by the Critical-Care Pain Observation Tool (CPOT)? Does ETT suctioning increase certain chemicals in the blood (hypoxanthine, xanthine, and uric acid) that show stress and lack of oxygen in the body? Researchers will compare patients who have ETT suctioning (intervention group) with those who do not have suctioning during the study period (control group) to see if there are differences in pain and blood markers of stress. Participants will: Have pain measured before and after suctioning using the CPOT. Have blood samples taken from an existing line at three time points: 5 minutes before, 5 minutes after, and 30 minutes after suctioning. Provide demographic information (like age, gender, and diagnosis) from medical records. This research will help improve how pain is managed for ICU patients who cannot speak for themselves, potentially leading to better pain relief methods in the future.

Lavender Aromatherapy to Decrease Anxiety/Pain Perception During Office Hysteroscopy
Description

Office hysteroscopy is an invaluable practice to treat a myriad of gynecological processes. However, a limiting factor is the perceived pain and anxiety. In a randomized pilot study, treatment with lavender aromatherapy will significantly decrease the stress/anxiety levels associated with office hysteroscopy, as measured on a visual analogue scale and the Hospital Anxiety and Depression Scale (HADS) questionnaire when compared to control subjects receiving distilled water placebo.

RCT of Pain Perception With Fast and Slow Tenaculum Application
Description

This project will be a randomized controlled trial (RCT) measuring pain perception with two different tenaculum placement techniques on the uterine cervix. A tenaculum is an instrument used to hold the cervix (the opening to the uterus or womb) in place. The trial will measure pain perception with a Visual Analog Scale (VAS) from 0 to 100 mm for two different tenaculum placement techniques, fast and slow closure on the uterine cervix. The main objective of this study is to determine if there is a difference in pain perception with fast compared to slow tenaculum placement techniques on the uterine cervix. We hypothesize that the slow technique will be perceived as less painful for subjects as measured on a 0 mm to 100 mm Visual Analog Scale (VAS). Subsidiary objectives include describing overall pain levels during the procedure.

COMPLETED
Pediatric Pain Optimization After Tonsillectomy
Description

The purpose of this study is to compare the use of short acting opioids (fentanyl/hydromorphone) with long acting opioids (methadone) for pain control following tonsillectomy surgery.

COMPLETED
Ketamine Versus Fentanyl for Surgical Abortions
Description

Ketamine is commonly used for procedural sedation and analgesia. It is widely used for trauma cases in the emergency department and is considered a superior agent in the outpatient setting due to its lack of respiratory and cardiovascular depression. In chronic opioid users, ketamine decreases acute pain and reduces postoperative opioid consumption. Few studies have examined the use of ketamine for surgical abortions. Previous studies found significant rates of emergence phenomena; however, this can be prevented if a benzodiazepine is given at the same time. Ketamine deserves further study to determine whether it is an acceptable alternative to a standard opioid-based regimen for surgical abortion. Our primary objective is to compare patient satisfaction after surgical abortion among patients receiving IV ketamine versus IV fentanyl for procedural sedation. Our secondary objectives include postoperative pain, additional pain medication used, and postoperative opioid use after the procedure. Our hypothesis is that ketamine will provide similar patient satisfaction and reduce postoperative opioid use. This will be a randomized controlled noninferiority clinical trial of 84 women receiving either IV ketamine with IV midazolam or IV fentanyl with IV midazolam for outpatient one day surgical abortions up to 13, 6/7 weeks gestation. Both groups will receive a standardized paracervical block and additional pain medication as needed. Our study has the potential to introduce IV ketamine as a satisfactory medication for outpatient surgical abortions. Ketamine may decrease the need for IV fentanyl, reduce postoperative opioid use, and may prove to be a superior analgesic for chronic opioid users.

Saphenous Nerve Block for Partial Meniscectomy
Description

Partial meniscectomy and meniscus repair are two of the most common orthopedic surgery procedures. As these procedures are being increasingly performed in ambulatory surgical centers, there has been a shift towards providing improved analgesia to ensure timely discharge, as well as preventing unwanted pain and side effects. As such, it has become common practice to use an intra-articular injection of local anesthetic to achieve post-operative pain control. However, these effects are short lived, requiring a multimodal approach to analgesia. To date, no optimal pain control strategy has been described for arthroscopic partial meniscectomy or meniscus repair. The purpose of this study is to examine the outcomes of subcutaneous saphenous nerve block with 0.5% ropivacaine at the medial femoral epicondyle/adductor hiatus plus portal 0.5% ropivacaine injection vs portal 0.5% ropivacaine injection alone for patients undergoing arthroscopic partial meniscectomy or meniscus repair.

Trauma-Informed Procedural Pain Intervention: Refinement of an Evidence-Based Protocol
Description

The Trauma-Informed Procedural Pain Intervention (TIPPI-R) has been developed as a standardized way to provide education and teach evidence-based strategies for managing pain and distress that may occur during pediatric cancer treatment. The purpose of this clinical trial study is to test how helpful TIPPI-R is in supporting children and families manage pain and distress during the initial stages of cancer treatment. The main questions this study aims to answer are: * Does TIPPI-R increase use of helpful pain coping strategies for pediatric cancer patients? * Does TIPPI-R help lower perceived pain intensity during initial stages of cancer treatment? * Does TIPPI-R increase patient and family confidence in coping with pain and distress during cancer treatment? Researchers will compare pain experiences and use of pain coping strategies for families who receive the TIPPI-R intervention and families who receive standard of care to see if TIPPI-R decrease pain and distress during the initial stages of cancer treatment. Participants will: * Complete surveys to measure pain and distress within 5 weeks of initial diagnosis (Time 1) * Either receive the TIPPI-R intervention or standard of care * Complete surveys to measure pain and distress 4 weeks after initial consent or TIPPI-R intervention delivery (Time 2)

Intravenous Ketorolac Administration to Attenuate Post-procedural Pain Associated With Intrauterine Device Placement
Description

Intrauterine devices (IUDs) are a popular form of long-acting reversible contraception, with a high efficacy rate and few side effects. The insertion procedure for IUDs can be uncomfortable and painful. Sedation may be needed to improve patient comfort. The use of IUDs is increasing in the adolescent population, but perceived pain is a barrier to placement. Propofol is a commonly used agent for pediatric procedural sedation, but it has no analgesic properties. Ketorolac, a nonsteroidal anti-inflammatory drug, has been shown to reduce pain in adults and improve patient satisfaction when used prior to IUD placement.. The current study aims to determine if ketorolac, given in combination with propofol for IUD placement in adolescents, can improve comfort during placement and reduce pain following the procedure. Enrolled patients will receive ketorolac or placebo, in addition to propofol, for IUD placement. By comparing the outcomes of these two groups of patients, we can gain a better understanding of the optimal approach to sedation for IUD insertion in adolescents.

Effectiveness of IV Acetaminophen and IV Ibuprofen in Reducing Post Procedural Pain in the UFE Procedure
Description

The uterine fibroid embolization (UFE) procedure is a treatment option for abnormal heavy menstrual bleeding and/or bulk symptoms associated with uterine fibroids and adenomyosis. Post UFE procedural pain and nausea are expected events. These symptoms are treated with current standard of care medications, including opiates. Intra procedure pain medications include midazolam, fentanyl and hydromorphone. Some centers include nonsteroidal anti-inflammatory medications (NSAIDS), including oral ibuprofen and IV ketorolac. Post procedural pain control is centered on a hydromorphone patient-controlled analgesia (PCA) infusion pump, as well as a NSAID regimen. Intra procedure and post procedure nausea control medications include a transcutaneous scopolamine patch and IV anti-nausea medications such as ondansetron and prochlorperazine. This study is being conducted to compare two new medications for pain, IV ibuprofen and IV acetaminophen, administered for 24 hours following UFE. The primary safety objective of non-inferiority will be met and the primary efficacy objective of superiority, decreased pain and nausea, will be accessed when compared to current standard of care regimens. This is a 4 arm, double blind, randomized, controlled study. All patients will receive standard of care baseline pain medications, including IV midazolam, fentanyl and hydromorphone intra procedure, followed by a hydromorphone PCA infusion pump post procedure. The 4 arms will include: \[ Arm 1\] IV ibuprofen/IV placebo, \[Arm 2\] IV acetaminophen/IV placebo, \[Arm 3\] IV ibuprofen/IV acetaminophen, and \[arm 4\] IV placebo/IV placebo. These medications will be given during the procedure and extended over a 24 hour stay. Arm 4 (IV placebo/IV placebo) would replicate current standard of care, and therefore will include IV push (IVP) ketorolac, which would be given at the end of the procedure and be continued every 6 hours for the 24 hour stay. An IVP of saline will be given as a control every 6 hours for the 24 hour stay to arms 1, 2 and 3. Pain and nausea will be measured at intervals prior to the procedure, throughout the stay and at 2 weeks post procedure.

Non-pharmacological Interventions for Procedural Pain in Premature Neonates
Description

A. Specific Aims Premature infants admitted to the neonatal intensive care unit (NICU) require up to several hundred procedures during their hospitalization. Many of these are tissue-damaging procedures (TDPs) known to cause pain \[1\]. Through funding from NINR, the investigators found that TDPs not only caused pain but also increased markers of ATP degradation and oxidative stress\[2\[. The TDP was tape removal, a commonly performed procedure in the NICU2. Based on this finding, the investigators sought to determine if interventions that relieve pain also reduce biochemical markers of ATP degradation and oxidative stress. The investigators first examined the effect of oral sucrose, a commonly used intervention, when given before a heel lance. The investigators chose heel lance because it is the most predominant painful procedure in the NICU, as shown in 29 different clinical trials\[3\]. The investigators hypothesized that since oral sucrose is documented to significantly reduce pain scores, then administration of this analgesic will also decrease markers of ATP degradation and oxidative stress. However,the investigators observed the opposite effect. Although a single dose of oral sucrose reduced behavioral markers of pain, it significantly increased biochemical markers of ATP degradation (hypoxanthine, uric acid) and oxidative stress (allantoin) over time\[4\]. More importantly, the effect of oral sucrose on breakdown markers of ATP were enhanced and were significantly higher in neonates that were intubated or were receiving more than 30% FiO25. These findings lead to the question: If oral sucrose does not effectively reduce the biochemical effects of procedural pain, what intervention or groups of intervention will decrease both behavioral markers of procedural pain and reduce ATP utilization and oxidative stress in premature neonates? For this RO1 renewal, the investigators propose to test the individual and additive effects of two commonly used interventions for procedural pain. These interventions are (a) administration of 30% oral glucose and non-nutritive sucking (NNS) (b) facilitated tucking and NNS c) administration of 30% oral glucose, facilitated tucking and NNS. Administration of 30% oral glucose was documented to decreased procedural pain scores\[6-9\] without the potential adverse effects of fructose, a key ingredient of sucrose\[10-11\]. Facilitated tucking is the gentle positioning of preterm infants with arms and legs in a flexed, midline position close to the body, while either in a side-lying or prone position\[12\]. Because tachycardia often accompanies pain, a documented benefit of facilitated tucking is stabilization of heart rate and reduction of motor activity (flailing)\[12-13\]. Non-nutritive sucking refers to the provision of a weight-appropriate pacifier\[14\]. The painful procedure will be a clinically required heel lance, which refers to the puncture of a newborn's heel for blood glucose using a specially designed lancet. Our general hypothesis is that commonly used clinical interventions known to reduce procedural pain alter biochemical markers of ATP degradation, oxidative stress and cell injury. Specific Aim 1 will determine whether (a) 30% oral glucose and NNS or (b) facilitated tucking and NNS or (c) 30% oral glucose with facilitated tucking and NNS will decrease procedural pain. • Pain will be quantified using a validated pain scoring tool, the Premature Infant Pain Profile (PIPP). Individual and additive effect of interventions will be determined. Specific Aim 2 will determine whether (a) 30% oral glucose and NNS or (b) facilitated tucking and NNS or (c) 30% oral glucose with facilitated tucking and NNS will decrease biochemical markers of ATP degradation, oxidative stress and oxidative cell injury. * Products of ATP breakdown in plasma-hypoxanthine (Hx), xanthine (Xa), and uric acid (UA)-will be measured using high performance liquid chromatography. * Oxidative stress will be quantified by measuring plasma levels of allantoin using mass spectrometry. * Cell injury will be quantified by measuring plasma levels of F2 isoprostane using liquid-chromatography/mass spectrometry.

Active vs Passive Distraction on Procedural Pain in the Pediatric Emergency Department
Description

The investigators proposed study will investigate the efficacy of tablet computer distraction as an analgesic for the pain associated with various painful procedures in the emergency department. Since prior studies have shown that distraction by a parent or nurse can be an effective analgesic, there is reason to believe that tablet computer distraction will similarly reduce pain. Participants in the control group will receive a cartoon on the TV monitor in the patient room, while participants in the study group will receive a more immersive distraction of playing a game or watching a cartoon (for children too young to play a game) on a tablet computer. Data from this study will help inform best practices for administering painful procedures in a way that minimizes pain.

Oral Sucrose Versus Glucose for Procedural Pain in Premature Neonates
Description

Premature neonates admitted to the neonatal intensive care unit (NICU) require up to several hundred procedures during their hospitalization. Many of these are tissue-damaging procedures (TDPs) that cause pain. Through our NIH funded research, we made the novel observation that exposure to a single TDP can significantly increase ATP utilization and oxidative stress, as evidenced by increased plasma levels of hypoxanthine, uric acid and malondialdehyde in neonates exposed to TDPs as compared to controls (no TDP). Because neonates are exposed to numerous TDPs, it is relevant to explore the energy costs of repeated exposures to painful procedures, an important information that is currently not known, as the effect of this cumulative metabolic dysfunction could result in potentially treatable or preventable cell injury. Oral sucrose analgesia is frequently given to relieve procedural pain in neonates on the basis of its effect on behavioral and physiological pain scores. However, we found, through our prospective, randomized, double blind study funded by NIH, that although oral sucrose significantly reduced pain scores, its administration before a single TDP (heel lance) significantly increased ATP utilization. This is evidenced by higher plasma concentrations of hypoxanthine and uric acid in neonates given sucrose compared to control neonates (no TDP, no sucrose) or neonates just given a pacifier. These novel findings raise concern because preterm neonates have limited ATP stores and are susceptible to cell injury due to ATP depletion. In addition, it raises the relevant concern: If a single dose of oral sucrose can alter ATP metabolism, what are the effects of exposure to multiple doses of oral sucrose? More importantly, what is the effect of multiple TDPs and/or multiple oral sucrose dosages on ATP utilization, oxidative stress and cell injury? This application will also explore the effect of 30% oral glucose, another sweet solution currently used to relieve pain, on ATP metabolism. In this study, we will test the general hypothesis that exposure to multiple TDPs and/or multiple doses of oral sucrose analgesia compared to oral glucose or standard care, alter biochemical markers of ATP utilization, oxidative stress and cell injury. We will use a prospective randomized clinical research design to test this hypothesis during days of life 3-7 of human premature neonates. Increased ATP utilization will be quantified by concentrations of hypoxanthine, xanthine and uric acid measured using HPLC. Oxidative stress will be quantified by concentrations of allantoin using gas chromatography/mass spectroscopy, and cell injury will be quantified through urinary concentration of intestinal fatty acid binding protein, an early marker of enterocyte injury. Data from this application will provide insight into the cellular and biochemical effects of repetitive and accumulated TDPs and/or multiple doses of oral sucrose. With this knowledge, we will propose and test innovative strategies that will not only decrease pain but also will prevent cell injury or cell death.

Self-Adjusted Nitrous Oxide: A Feasibility Study in the Setting of Vasectomy
Description

This study is being done to see if nitrous oxide during vasectomy decreases pain and anxiety, and also assess whether patients have better satisfaction when they control their own level of nitrous oxide during the procedure. If we find that patients experience less pain or anxiety with nitrous oxide, it could be suggested that self-adjusted nitrous oxide (SANO) may be a useful tool for improving experience of care during vasectomy.

Addition of Buprenorphine to Paracervical Block for Pain Control During Osmotic Dilator Insertion
Description

Cervical preparation with osmotic dilators is commonly used prior to dilation and evacuation (D\&E) procedures to decrease the risk of complications. Women have described the pain of osmotic dilator insertion as moderate to severe yet there have been few studies aimed at addressing pain during and after osmotic dilator insertion. In addition to the discomfort during insertion, pain after osmotic dilator insertion peaks at 2 hours post-insertion with use of a lidocaine paracervical block. One randomized trial found that use of a paracervical block with 1% buffered lidocaine decreased pain with osmotic dilator insertion compared to a sham block. There are adjunct treatments to optimize analgesia with local anesthetics at a variety of anatomic locations. Buprenorphine, a partial mu-opioid receptor agonist, has been found to increase the quality of the anesthetic at the time of administration and increase the duration of nerve block analgesia at several anatomic sites, though has never been studied as an adjunct in a paracervical block. This has been used extensively in orthopedic surgery with significant prolongation of the local anesthetic effect by almost threefold in some studies. Primary Aim: To compare the mean pain score at the time of osmotic dilator insertion among women randomized to a 1% lidocaine and buprenorphine paracervical block compared to a 1% lidocaine paracervical block alone. Secondary Aim: To compare the mean pain score 2 hours after osmotic dilator insertion among women randomized to a lidocaine and buprenorphine paracervical block compared to a lidocaine paracervical block alone. The investigators hypothesize that in patients undergoing osmotic dilator insertion in preparation for dilation and evacuation, the addition of buprenorphine 0.15mg to a 1% lidocaine paracervical block will be associated with lower mean pain scores at time of osmotic dilator insertion compared to women who receive a 1% lidocaine paracervical block alone.
