The investigators will approach elective cardiac and thoracic surgery patients in the preoperative consultation clinic. Consenting individuals will be administered, before surgery validated pain, psychological and sleep questionnaires. These questionnaires will be repeated at 3, 6 and 12 months postoperatively (PO) to follow up the progression of early PO pain and the transition to chronicity. Participants will define clinically relevant pain by calculating a chronic pain index (CPI). In addition, the investigators will follow the development of acute postsurgical and chronic pain from before surgery up to a year after, extract DNA from blood and contrast the genetic variations of participants with clinically significant chronic pain, to identify variations associated with the development of chronic post-surgical pain.
This study aims to assess the post-dental extraction pain following the application of two different dressing materials. Alvogyl® and Absorbable gelatin sponges
The goal in this work is to compare the effect of intravenous single-bolus lidocaine infusion versus intravenous single-bolus magnesium sulfate infusion on postoperative pain, emotional status and quality of life in patients undergoing spine fusion surgery.
Chronic pain, functional impairment and slow rates of recovery are key issues for patients after surgery and trauma. No preventative strategy in current use unequivocally modifies these rates, and few novel approaches have been tested. Furthermore, persistent postsurgical pain is a major route to chronic opioid use, opioid use disorder and, regrettably, opioid overdose. Most strategies designed to limit chronic pain or enhance functional recovery after surgery are directed at modulating peripheral and central nervous system activity and do not strongly modify the underlying tissue pathophysiology or fundamental systemic responses. Strategies limiting oxidative stress in the perioperative period, on the other hand, might limit tissue damage, organ dysfunction and immune system activation. N-acetyl cysteine (NAC) is an antioxidant well-studied in the perioperative period; it is very safe, relatively inexpensive and widely available. The central hypothesis is, therefore, that perioperative administration of NAC will reduce perioperative oxidative stress, limit immune system activation and improve key indices of surgical recovery. Although the planned work will not comprehensively address this hypothesis, it will identify the most useful tools and help the researchers estimate the required sample sizes for more definitive externally funded efforts.
The study is being conducted to evaluate the efficacy, safety of HR021618 and to explore the reasonable dosage of HR021618 for Pain Management after Orthopaedic surgery.
This pilot research study is being performed to learn more about pain and look at how pain changes brain chemistry and function. The research team would like to learn new information to better control chronic pain after surgery. This information collected in this research will be used to plan possible future visits. Participants in this study are being asked to participate because they are scheduled for an upcoming surgery. The research team would like to observe them before and after their surgery.
Hypnosis is an effective pain management tool for surgery that can reduce opioid use up to 40%. COMT single nucleotide polymorphisms (SNPs) can predict pain sensitivity and opioid use perioperatively, and may also be associated with hypnotizability or response to hypnotic analgesia. Analyzing COMT haplotypes from DNA extracted from saliva or blood using a giant magnetoresistive (GMR) nanotechnology platform may be faster, less expensive, and at least as accurate as pyrosequencing. This study aims to validate a multi-SNP point-of-care (POC) GMR assay for the rapid genotyping of SNPs predictive of COMT activity, and test the feasibility of using COMT activity as a biomarker for hypnotizability and/or response to hypnotic analgesia.
Chronic pain is an extremely disabling disease. It is a major public health problem due to the lack of effective therapy. Chronic postoperative pain (CPOP) is defined by a painful symptomatology in the operated area unrelated to previous pain, present for more than 3 months, and without any link to surgical complication. The prevalence of chronicization of postoperative pain is 30% after total knee arthroplasty. Identification of clinical, biological and psychological profiles are crucial to prevent CPOP. A biologic factor, Brain Derived Neurotrophic Factor (BDNF) produced by a variety of cells is a key regulator of neuroplasticity. BDNF is increasingly studied in the mechanisms of cerebral sensitization and pain chronicization. The role of BDNF in pain of patients remains to be explored in a prospective study. The aim of this observational study is to compare the kinetics of BDNF after total knee arthroplasty in patients with and without CPOP. Patients will be included in the study at the preanesthetic consultation. Serum BDNF levels will be measured preoperatively, 48h postoperatively, 3 and 6 months after surgery.
"Cryotherapy", or cold therapy, can include the use of gel packs, ice bags, ice baths, whole body chambers, and cold aerosol sprays. It is a popular non-drug treatment that can be used after a surgical operation, along with medication such as narcotics and anti-inflammatories for pain management. The application of ice packs on areas of injury has been used for many decades, as they can decrease both inflammation and pain. Other possible benefits include reduced blood flow, swelling, and tissue damage as well as muscle spasms. While there is some evidence to suggest that the use of ice packs is beneficial, this has not yet been implemented into practice, nor do any guidelines recommend the use of ice packs for pain management in surgical patients. In this trial, adult patients undergoing scheduled thoracoabdominal or groin surgery will be randomly assigned to apply ice packs over the largest closed surgical incision every 4 hours, at minimum, for 72 hours (while the patient is awake), along with standard of care, or to receive standard of care only. This trial will be conducted under the IMPACTS (Innovative, Multicentre, Patient-centred Approach to Clinical Trials in Surgery) program umbrella and will follow IMPACTS methodology. For the Vanguard trial, the aim is to determine the feasibility of conducting a definitive trial. Future outcomes of interest are quality of patient recovery, pain, length of hospital stay and medication use.
