Active clinical trials for "Pain, Postoperative"

The main aim of this research is to compare the functional recovery after discharge with the preoperative physical activity as a hypothesis generating study.

The primary purpose of this prospective cohort study is to develop a simplified risk model for post-discharge nausea and vomiting (PDNV) in adult same-day surgery patients in the US that will allow clinicians to identify those patients who would benefit from prophylactic antiemetic strategies.

Observational study evaluating pain response after total knee arthroplasty (TKA) in patients taking strong, weak or no opioids preoperatively.

In this study we evaluate if there is a correlation between acute pain and systemic inflammatory markers after total Knee Arthroplasty (TKA).

In this consecutive, prospective cohort study the investigators evaluate if preoperative pain response upon heat stimulation is predictive for acute and subacute postoperative pain after total hip arthroplasty.

This study aims to investigate the potential association between pain sensitivity questionnaire score, the severity of postoperative pain, and postoperative analgesic requirement in patients with open colorectal cancer surgery. This information may be used to guide the optimal postoperative pain management, and ultimately improve patient's quality of life.

Post Mastectomy Pain Syndrome (PMPS) is a major complication of breast surgery responsible for depression and disability. The project consists of a prospective cohort on patients going for oncological breast surgery at National Institute of Oncology of Rabat. Chronic postoperative pain (CPP) remains a disturbing and obscure clinical problem, which could last for more than 3 months after surgery. The aim of present study was to assess the prevalence of CPP, investigate its impact on life quality and explore its potential risk factors. After informed consent was signed, patients receiving surgery under general anesthesia in Peking Union Medical College Hospital and other medical centers participating in this study during 2018 will be included. Patients' preoperative information will be collected from medical record, including basic demographic data, primary disease and previous chronic diseases. Intraoperative information will be obtained from anesthesia record, including surgical scope, duration, length and location of incisions and blood loss. Acute pain will be evaluated in the ward of the department of surgery, when an app will be installed on patients' mobile phones. Our long-term postoperative follow-up would be performed by sending out survey questionnaires via this app in the 4th, 8th, 16th, 32th, and 48th weeks after surgery. The survey covers questions regarding the intensity, characteristic, location and impact on daily activities of CPP. Information regarding treatment of CPP will also be collected, if any. All the data gained will be summarized in our database and analyzed.

One out of 10 patients undergoing surgery develops persistent post-surgical pain (PPSP). Unfortunately, available therapies for treating this pain have limited success. It is therefore of great importance to find strategies to prevent PPSP. The goal of this project is to find new screening tools that identify patients that are at risk for developing PPSP. Tissue injury and inflammation following surgery increase the excitability of spinal nociceptive neurons ("central sensitisation", CS) with pain hypersensitivity as consequence. It is thought that CS plays an important role in persistent pain. The first objective of this project is to assess in human patients if the propensity to develop CS manifested as secondary hyperalgesia before surgery is predictive for PPSP. In addition, we will test if the frequency content of the resting-state EEG reflecting the initial state of the brain will be related to the propensity for developing CS and to the presence of PPSP at two months after surgery.

The aim of this study is to compare the total morphine consumption in the first 24 hour postoperative between combined modified pectoralis block (PECS II) and transversus plane block versus erector spinae block in modified radical mastectomy.
