Active clinical trials for "Pain, Postoperative"

Postoperative pain remains an important challenge for both patients and clinicians. Despite advances in pain management techniques, many patients continue to describe their pain as moderate to severe immediately after surgery. Poor postoperative pain control is associated with increased morbidity, functional impairment, and higher health care costs. While opioids currently represent the mainstay of treating surgical pain, their use is associated with significant side effects including respiratory depression, delayed recovery of bowel function as well as the potential for long-term use. Therefore, there is an urgent need to find new pain relievers with a safer side effect profiles. One such drug that has been receiving increasing attention is ketamine. Previous studies have focused on using intravenous ketamine postoperatively which requires a monitored setting but have ignored the oral form. By using the oral route of administration, ketamine could potentially be used by patients in a less resource-intensive manner with similar efficacy. Therefore, Investigators propose to conduct the Ketamine for Acute Postoperative Analgesia (KAPA) pilot study to examine the role of oral ketamine in improving recovery after spine surgery.

This randomized clinical trial compares the effects of the erector spinae plane block with levobupivacaine and 0,9% saline on postoperative pain intensity, and opioid consumptions following thoracoscopic pulmonary surgery.

The investigators are going to study the difference in postoperative pain control after administration of oral versus intravenous formulation of acetaminophen

This study was to evaluate and compare the postoperative pain levels after using EndoActivator and conventional endodontic syringe irrigation in root canal therapy of primary molars.

The frequency of femoral nerve block and adductor canal block for analgesia after TKA(total knee arthroplasty) increases with the use of ultrasonography in regional anesthesia. In this study, we aimed to compare the effects of femoral nerve block and adductor canal block on postoperative analgesia in patients undergoing unilateral knee arthroplasty.

Laparoscopic cholecystectomy is the most common surgical procedure for removal of the inflamed gall bladder or other gall bladder pathologies. There are more than 12,000 cases of cholecystectomy performed in Taiwan annually, and more than 85% of this procedure are undertook with laparoscopic techniques. Even with minimally invasive laparoscopic operation, patients may still suffer from postoperative wound pain, deep visceral or referred pain. About 80% of patients who received laparoscopic procedures complain of moderate-to-severe pain within the first day after cholecystectomy. Most importantly, up to 20% (range from 3 to 20%) of these patients complained surgical-related pain one year after operation and they require prolonged use of opioid to control chronic postoperative pain (CPSP). However, there are currently lack of clinical practice guidelines or recommendations for prevention of CPSP after laparoscopic abdominal surgery. Although regional block techniques (i.e. truncal block or intrathecal opioid) are considered as effective supplementary analgesic approaches to improve postoperative pain control, parenteral administration of analgesics remain as the mainstay for pain management of laparoscopic abdominal surgery. Naldebain® is prodrug of nalbuphine, which was approved by the Taiwan FDA in 2017. Naldebain® is an extended-release dinalbuphine sebacate, and is rapidly hydrolyzed by tissue of plasma esterase to release nalbuphine. A number of clinical studies have shown that single-dose of pre-operative intramuscular administration of Naldebain® provides significantly higher analgesic effect up to 1 week in hemorrhoidectomy and laparotomy surgery with a well-tolerated safety profile. Therefore, this PI-initiated randomized, double-blind, placebo-control trial aims to investigate the clinical efficacy of Naldebain® in management of acute postoperative pain in patients receiving laparoscopic cholecystectomy, and prevention of the development of CPSP after surgery.

Scoliosis is a 3-dimensional, structural deformity of the spine. Idiopathic scoliosis is the most common type and it constitutes 75-80% of all scoliosis. Surgical methods are the most effective way to correct the deformity in patients who cannot achieve adequate improvement with supportive therapy. Adolescent idiopathic scoliosis surgeries are among the most invasive surgeries performed on children and adolescents. Large surgical incision and massive tissue damage cause severe postoperative pain. In this study, we aim to compare posterior instrumentation (PE) and vertebral body tethering (VBT) surgeries performed in adolescent idiopathic scoliosis patients in terms of anesthetic management and postoperative pain.

Although radial extracorporeal shock wave therapy (rESWT) has proven to be an effective treatment, the effectiveness of the treatment has so far been controversial. There are no studies using rESWT in rehabilitation after arthroscopic rotator cuff repair (ARCR). Therefore, in this study, there is evidence that rESWT promotes pain control and healing recovery, and through previous studies, we would like to investigate whether treatment with rESWT during the intensive rehabilitation period of patients after ARCR is more effective in controlling pain.
