Active clinical trials for "Pain, Postoperative"

This will be a prospective trial comparing the perspective gross morphological of bladder tumor assessment done by outpatient flexible cystoscopy performed by resident, inpatient rigid cystoscopy done by senior staff and their prediction of the degree of invasion of bladder tumor plus the prediction of the grade compared with the standard pathological result. Also, assessment of the patient reported outcomes after both flexible and rigid cystoscopy will be done. In the long run of the study, the prognostic gross morphology with recurrence, progression and cancer specific survival will be assessed.

Infantile hypertrophic pyloric stenosis (HPS) is one of the most common gastrointestinal medical emergencies.This retrospective study will review the files of all infants with HPS, who were treated by open pyloromyotomy under spinal anesthesia in the Bnai Zion Medical Center between the years 2006 to 2015.

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.

This study aims to predict risk factors of acute postoperative pain of the patients undergoing Total Knee Replacement Arthroplasty(TKRA).

Post-operative pain will be measured using a pain diary for one week post-surgery. The purpose is to test the assumption that the arthroscopic technique leads to less post-operative pain and results in shorter hospital stays when compared to the open technique. It is believed that the arthroscopic technique will result in minimal pain when compared to the open technique, allowing this procedure to be performed as day surgery.

In prosthetic knee surgery, there is a certain number of patients with post-operative nocturnal pain. The purpose of our study is to determine the impact of this problem and to better understand its risk factors.

Chronic postsurgical pain had number of prevalence on 20%. Its derivates from risk factors, but recent research provide new potential risk factors to develop chronic postsurgical pediatric pain. To increase the body of knowledge, an observational study is proposed in pediatric patients undergoing surgical intervention.

Prospective, monocentric, observationnal study. The primary objective of this study is to identify if presurgical child or/and parental anxiety is predictive of chronic postsurgical pain in abdominal or urologic ambulatory surgery.

Painful osteoarthritis (OA) is the 4th largest cause of disability in the UK. Preoperative temporal summation, a measure of central pain facilitation, has been shown to predict postoperative pain after total knee replacement surgery (TKR). The assessment of the brain's response to noxious stimuli using non-invasive functional MRI (fMRI) may be key in identifying imaging biomarkers within the brain that map central sensitization changes seen in OA. fMRI may help explain why up to 20% of patients undergoing TKR surgery develop persistent post-operative pain. To test these concepts the study aims to functionally characterise the brain activity related to temporal summation of pain in healthy individuals and OA patients using a novel fMRI cuff algometer. Assessment of outcomes in terms of pain and function will be performed 6 months post TKR surgery

Postoperative pain and use of narcotic analgesics after laparoscopic bariatric surgeries are problems that need to be solved in terms of patient comfort. We believe that preincisional bupivacain injection to the trocar sites will help us for these problems. A study is designed focused on reduced postoperative pain and reduced use of narcotic analgesics by preincisional bupivacain injection for laparoscopic bariatric patients.
