  • Does Style of Pre-sedation Instructions Improve Patient Outcomes in Ambulatory Anesthesia for Oral and Maxillofacial Surgery?

    open to eligible people ages 8-70

    This randomized controlled trial aims to evaluate the impact of a brief guided visualization exercise on anesthesia-related outcomes in oral and maxillofacial surgery in patients scheduled for ambulatory anesthesia in the oral and maxillofacial surgery clinic. Researchers will compare these patients, who will receive the guided visualization exercise in addition to standardized pre-operative instructions, to patients who will only receive the standardized pre-operative instructions. The following outcomes will be measured for both groups: - A seven-point Anesthesia Experience Survey - Face-Legs-Activity-Cry-Consolability (FLACC) scores at three points in time during the anesthetic - during local anesthesia, during surgery, and fifteen minutes after surgery has concluded - Amount of medications used during the sedation - Length of sedation

  • Fasting on Patient Outcomes After Wide-Awake, Local Anesthesia-only, No Tourniquet (WALANT) Procedures

    open to eligible people ages 18 years and up

    The purpose of this study is to determine whether eating solid food prior to undergoing a wide awake local-only no tourniquet (WALANT) procedure reduces anxiety in patients or has any effect on outcomes. Patients will be split randomly into two groups and told whether to eat or fast before their procedure. We will then compare levels of anxiety and nausea on the day of the procedure as well as satisfaction with the procedure and other outcome measures at follow-up visits. Our hypothesis is that patients who are instructed to eat before their WALANT procedure will have less anxiety, nausea, and overall higher satisfaction compared to those who are instructed to fast prior to their procedure.

  • Patient Preference for Intraoperative Opioid Use on Early Postoperative Quality of Recovery

    open to eligible people ages 18 years and up

    Substituting the administration of opioids with a combination of alternative analgesics, known as opioid-free anesthesia (OFA), is gaining in popularity today and is typically administered as part of a larger multimodal strategy. However, OFA adoption is not as common today as one could expect from the potential benefits of limiting opioid use and patient involvement in the decision may impact its adoption. Relevant shared decision-making process with patients concerning the use or limited use of opioids could improve patient autonomy and empowerment. There have been no studies that have evaluated patient preference regarding opioid use and its potential impact on the quality of recovery. The aim of this study is to compare the effect of patient preference on intraoperative opioid use on early postoperative quality of recovery following moderate risk laparoscopic/robotic abdominal surgery.

  • 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.

  • Choice of Vasopressor to Prevent Postoperative Acute Kidney Injury After Major Non-Cardiac Surgery

    open to eligible people ages 18 years and up

    Low blood pressure, also known as hypotension, is very common during major surgery under general anesthesia. Prolonged or severe hypotension can lead to complications such as kidney injury after surgery that slow down patient recovery. Anesthesiologists commonly administer medications called vasopressors to treat low blood pressure during surgery. These medications help raise the blood pressure back up to a safe range. Two vasopressor medications are commonly used for this purpose: norepinephrine and phenylephrine. Each of these medications has slightly different effects on the heart and blood vessels (cardiovascular system). It remains unknown which of these standard medications is better for treating low blood pressure during surgery. The goal of this clinical trial is to determine which of these two medications is better at preventing injury to the kidneys after major noncardiac surgery as well as other complications such as heart problems. Major surgeries are defined as those lasting at least two hours under general anesthesia. This trial will randomize about ten centers in North America to use either norepinephrine or phenylephrine as the primary medication to treat low blood pressure in adults undergoing major noncardiac surgery. Each hospital will prioritize one of the drugs each month, and the assigned drug will rotate each month at each hospital. No further participant involvement will be required as de-identified data are collected as part of standard medical care.

  • Empathy Through Pain Control: Buffered Compared to Unbuffered 1% Lidocaine During IUD Placement

    Sorry, not yet accepting patients

    The goal of this research study is to learn more about how different uses of a numbing medication might affect pain levels while getting an IUD placed. The investigators are also studying patients' opinions of their clinicians' empathy. The investigators are inviting patients who have never given birth who arrive at their clinic visit seeking an IUD. Usually, at University of California, San Diego (UCSD), for patients who have never delivered, clinicians numb both the sides of the cervix with a lidocaine-based paracervical block. The purpose of this research study is to compare perceptions of pain between buffered (2 cc of sodium bicarbonate, 18 cc of 1% lidocaine) vs. unbuffered paracervical block (20 cc 1% lidocaine) during IUD placement for nulliparous women.

  • Empathy Through Pain Control: Lidocaine Paracervical Block for IUD Placements

    Sorry, not yet accepting patients

    The goal of this research study is to learn more about how different uses of a numbing medication might affect pain levels while getting an IUD placed. The investigators are also studying participants opinions of their clinicians' empathy. The investigators are inviting patients who arrive at their clinic visit seeking an IUD. Usually, at University of California, San Diego (UCSD), for patients who have never delivered a baby, clinicians use a buffered paracervical block for before IUD placement. The purpose of this research study is to investigate whether a "buffered" (2 cc of sodium bicarbonate, 18 cc of 1% lidocaine) paracervical block (numbing medication given on both sides of the cervix) is effective in reducing pain during IUD placement in individuals with prior C-sections, the difference between buffered and unbuffered for nulliparous patients, and whether a medicated gel reduces pain with the paracervical block.

  • Ethyl Chloride Spray to Reduce Pain From Local Anesthesia During Mohs Micrographic Surgery

    Sorry, not yet accepting patients

    Fear of needles is a well-documented issue that affects many patients. This fear may cause significant anxiety in various medical situations, including in the dermatology office 1. If not properly managed, needle phobia can persist, affecting a patient's experience during each visit. This effect may compound and lead to avoidance behaviors that can delay necessary treatments 2. This issue is particularly relevant in a Mohs micrographic surgery (MMS) clinic where each patient experiences several painful needle injections before the day is over. Ethyl chloride is gaining popularity among dermatologists for its routine use in clinical practice due to its anesthetic and antiseptic properties, especially as a pre-injection agent. Research indicates that cryotherapy or pre-cooling the skin before administering a local anesthetic may offer benefits over topical anesthetics, such as enhanced pain relief, quicker onset, and better patient compliance 3,4. However, to our knowledge, no studies have specifically examined the effectiveness of pre-cooling with ethyl chloride prior to Mohs micrographic surgery. To address this gap, we're conducting a trial aimed at evaluating the impact of pre-cooling with ethyl chloride on pain perception in adult patients undergoing Mohs micrographic surgery with local anesthetic injections. The trial is a single-center, split-body study. The split-body design will involve dividing the surgical site into two equal halves, with one half (right side relative to patient) designated as the treatment side (receiving ethyl chloride spray prior to lidocaine injection) and the other as the control side (no ethyl chloride spray prior to injection). During the procedure, the participant will be asked to rate the pain associated with the needle injection AND the pain from infiltration of anesthetic from each side of the wound using the visual analog scale (VAS) scoring system (1 = no pain, 10 = most amount of pain possible). The results of the study will help us better understand how to mitigate pain and anxiety for patients requiring MMS.
