The Effects of Endotracheal Suctioning on Pain and Serum Markers
Recruiting
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 suctio... Read More

Sequential and Comparative Evaluation of Pain Treatment Effectiveness Response
Recruiting
VETERANS ONLY. Chronic low back pain (cLBP) is common. Most Americans will have at least one episode of low back pain in their lifetimes. Approximately 50% of all US Veterans have chronic pain, and CLBP is the most common type of pain in this population. This study will use a sequential randomized, pragmatic, 2-step comparative effectiveness study design. The main goal is to identify the best approach for treating cLBP using commonly recommended non-surgical and non-pharmacological options. The... Read More

Propofol-Enhanced Assessment of Ketamine for Chronic Pain and Depression
Recruiting
The goal of this clinical trial is to compare ketamine to a placebo when given as a single infusion during IV sedation in adults with chronic pain and depression. We do not know whether ketamine will be more effective than placebo under these circumstances. This study aims to: * Evaluate whether placebo is non-inferior to ketamine in treating chronic pain and depression, when delivered under propofol sedation * Confirm that propofol sedation is a safe way to keep participants blinded to treatm...

TMS for Complex Regional Pain Syndrome
Recruiting
The aim of the current study is to assess the efficacy of TMS in the treatment of Complex Regional Pain Syndrome (CRPS). It is hypothesized that participants who receive TMS (Group 1) relative to sham treatment (Group 2) once daily for two days will demonstrate a greater improvement in CRPS-related pain and other associated symptomology (i.e., cognitive, emotional and physical) compared to baseline. Participants will be followed until they reach their baseline for two consecutive weeks to assess... Read More

No Opioids vs. Minimal Opioids Following Inguinal Hernia Repair
Recruiting
The investigators hypothesize that not prescribing opioids after uncomplicated, outpatient IHR will be non-inferior to prescribing opioids (5 tablets of Oxycodone, 5mg; or surgeon preference for intolerance) with respect to requests for opioid refills. Additionally, the investigators believe there will be no significant difference in postoperative readmission for pain quality of life at 30 days in either group.

A Clinical Trial of Intravenous Lidocaine After Spinal Surgery to Prevent Delirium and Reduce Pain
Recruiting
Postoperative delirium is one of the most frequent adverse events following elective non-cardiac surgery and is associated with cognitive impairment at discharge, as well as in-hospital and long-term mortality, however, despite being a well-recognized problem there is a dearth of effective interventions for prevention and management. A modifiable risk factor associated with postoperative delirium is poor postoperative pain control, and by improving the pain regimen the investigators may be able... Read More

Obstetric Placement Study Using EST
Recruiting
Combined spinal-epidural (CSE) is an established technique for providing labour analgesia to obstetric patients which provides rapid onset but unsustained analgesia. The epidural catheter can be used to extend and provide continuous pain relief, however during single-segment needle-through-needle CSE, the catheter is untested. This study aims to confirm placement of epidural catheters of anesthesia through the epidural stimulation test (EST) which was first described by the PI of the study for c... Read More
