Active clinical trials for "Pain, Postoperative"

For some kinds of surgery, Anesthesiologists provide nerve blocks (regional anesthesia) to reduce pain from surgery by injecting freezing medication around deep nerves with ultrasound. Nerve blocks help with pain control following surgery and reduce the amount of strong opioids needed but relatively little research has focused on the pain that occurs once the nerve block has worn off. This is called rebound or transition pain. This research study will prospectively collect data including pain scores before, during and after nerve blocks are given for surgery. We will look at the type of nerve blocks and other analgesia medications used with the aim of quantifying rebound pain to better understand how to limit it's impact on quality postoperative pain control.

Chronic postoperative pain is a well-known problem. Chronic postoperative pain is defined as pain that begins following a surgical procedure and persists for more than 2 months without other obvious causes such as infection or underlying disease. Sternotomy causes significant postoperative pain, and patients with chronic pain after sternotomy are often referred to pain clinics. The incidence of chronic pain after sternotomy ranges from 17% to 56%; In approximately one-third of these patients, chronic pain after sternotomy can compromise their quality of life by affecting their sleep patterns and impairing their ability to work. However, epidemiological studies on chronic pain after sternotomy are scarce. The aim of this study is to examine the incidence and possible risk factors of chronic pain following sternotomy operations. In this study, it was aimed to analyze the chronic pain findings of the patients who underwent sternotomy in the postoperative 3rd month.

The indicators of patient recovery in the postoperative period include sleep, physical functionality, mental health, cognitive functionality, pain, and psychosocial functionality. This thesis aims to investigate the effects of progressive relaxation exercises on postoperative pain intensity, sleep quality, and recovery in patients undergoing total knee arthroplasty.This study, designed as a randomized controlled experimental study, will be conducted between September 1, 2023, and August 1, 2024, at ÇAYCUMA State Hospital in ZONGULDAK province, Turkey, among patients undergoing total knee arthroplasty. A total of 96 patients will be recruited based on the sample size calculated using G-power analysis. Through block randomization, 48 patients will be assigned to the intervention group and 48 patients to the control group. Data will be collected using the Numeric Rating Scale for pain, the Richard-Campbell Sleep Scale, a sleep tracker smart wristband to measure sleep quality and duration, the Postoperative Recovery Index, and a Patient Information Form.

The objective of this study will be to compare two methods of skin incisions during the first caesarean section (CS), that is scalpel and diathermy, assessing differences in blood loss during incision, incisional time, total surgery time, post-operative pain, wound healing, complications, and cosmetic outcomes.

The delivery of the infant into the arms of a conscious and pain free mother is one of the most exciting and rewarding moments in medicine. Neuraxial anesthesia is now the preferred technique for lower segment cesarean sections (LSCS). Although epidural, spinal, continuous spinal, and combined spinal-epidural techniques have all been advocated, most cesarean sections are performed under single-shot spinal anesthesia. Even when a long acting local anesthetic like bupivacaine is used, the duration of spinal anesthesia (SA) is short and higher doses of analgesics are required in the postoperative period. Therefore, achieving a subarachnoid block that provides high quality postoperative analgesia of consistently prolonged duration is an attractive goal.

Circumcision is one of the most commonly performed operations in the pediatric population and is a painful procedure. Circumcision is performed with two popular techniques, Plastibell and conventional dissection method (CDM). For intra-operative (OP) and post-OP pain relief, two commonly used local anesthetic techniques are caudal block (CB) and dorsal penile block (DPNB) plus ring block (RB) at the base of the penis. There are very few randomized controlled trials comparing these two methods of intra-OP and post-OP pain relief, for different surgical techniques and there is a lack of well-conducted studies comparing the quality of analgesia, need for rescue analgesia in the early post-OP period, complications, and parental satisfaction comparing these blocks. Furthermore, there is a lot of contradiction in the literature regarding the duration of analgesia produced with these techniques.

Open renal surgeries are associated with significant postoperative pain; early control of the perioperative pain is associated with decrease of hemodynamic variations during the surgery, early mobilization, better quality of functional recovery & early discharge of patients. Side effects of systemic opioids, as well as difficulty to monitor their response, are major limitations to their use. Pediatric regional anesthesia (PRA) is one of the most valuable and safe tools to treat perioperative pain, and is an essential part of modern anesthetic practice. Neuraxial analgesia for pediatric patients is a mode of pain control that gained popularity in the last few decades as it decreases opioid exposure, shortens recovery room time & hospital stay. Caudal block is the most commonly used neuraxial anesthesia in pediatric patients. However, its major side effect is urinary retention and excessive motor block. Considerable progress has been made in the practice of PRA over the past few years including incorporation of ultrasound guidance, with promising novel regional anesthesia techniques, especially the anterolateral and the posterolateral trunk blocks. In this study, the investigators will compare the ultrasound guided quadratus lumborum block (QLB) with erector spinae plane block (ESPB), regarding the duration and quality of postoperative analgesia in pediatric patients undergoing unilateral open renal surgeries under general anesthesia. The study hypothesis is that QLB can provide a more superior postoperative pain relief to ESPB in children undergoing open renal surgeries.

Adeno-tonsillectomy is one of the most common surgeries in children. The most common complication associated is postoperative pain. If not well controlled, especially in preschool children, it can lead to a longer recovery period, delayed discharge, and nutritional deficiencies resulting in dehydration. These factors will increase hospitalization period and the need for intravenous fluids. For this purpose, a large number of studies has been designed to evaluate the analgesic effects of various drugs during the perioperative period. Opioids are associated with sedation and respiratory depression, NSAIDs increase the risk of reoperation for bleeding while local anesthetics may cause vasoconstriction of the operation site. For several years, N-methyl-D-aspartate (NMDA) receptors antagonists, such as ketamine and magnesium, have been used successfully to decrease postoperative pain and analgesic requirements in adult patients undergoing a number of different procedures. Ketamine reduces the needed analgesia after tonsillectomy. Most studies have shown that ketamine administration has no side effects such as hemodynamic, respiratory complications and airway problems. Magnesium is a physiological antagonist of the NMDA receptor ion channel that plays a key role in central sensitization. Many studies have investigated the effect of magnesium sulphate on postoperative pain and opioid consumption. However, results of those studies were variable. Whereas most studies describe the reduction of postoperative analgesic requirements after magnesium sulfate, a few studies show insignificant beneficial effects. A previous study evaluated the effect of low dose ketamine (0.15 mg/kg) and magnesium sulfate (30 mg/kg) on post tonsillectomy pain in children, which did not demonstrate a decrease in pain or analgesic consumption in children undergoing tonsillectomy. In this study, the investigators will increase the dose of ketamine to (0.5 mg/kg) and magnesium sulfate to (40 mg/kg) to evaluate their effect on postoperative pain in pediatric patients undergoing adeno-tonsillectomy.

Postoperative analgesia after shoulder surgery remains a challenge in patients with preexisting pulmonary pathology, as interscalene brachial plexus block (ISB), the standard nerve block for shoulder surgery, carries a prohibitive risk of hemidiaphragmatic paralysis (HDP). Although several diaphragm-sparing nerve blocks have been proposed, none seems to offer equivalent analgesia to ISB while avoiding HDP altogether. For instance, even costoclavicular blocks, which initially fulfilled both requirements, were subsequently found to result in a non-negligible 5%-incidence of HDP. In this randomized trial, the authors set out to compare ISB and combined infraclavicular block-anterior suprascapular nerve blocks (ICB-ASSNB) for patients undergoing arthroscopic shoulder surgery. The authors hypothesized that ICB-ASSNB would provide equivalent postoperative analgesia to ISB 30 minutes after shoulder surgery and therefore designed the current study as an equivalence trial.

This study aims to determine the efficacy of a quadratus lumborum (QL) block in decreasing postoperative pain in patients undergoing myomectomy for uterine fibroids. A QL block is a temporary anesthetic injection in the quadratus lumborum muscle, a muscle in the lower back, that has been previously shown to significantly reduce postoperative pain levels in patients undergoing abdominal and pelvic surgery. Because of its demonstrated effects, the QL block is becoming a standard of anesthesia and surgical care. Since participants will be undergoing a myomectomy procedure, the investigators believe that participants may qualify to participate in this study. The investigators will be comparing patients who receive the QL block (in addition to standard anesthesia and postoperative pain care) with patients who do not receive the QL block (in addition to standard care). The participants will be randomly assigned to one of the two groups and may or may not actually receive the block.
