Active clinical trials for "Pain, Postoperative"

Inguinal hernia repair is one of the most frequently performed operations in young men. Persistent pain after inguinal surgery represents a significant cause of disability, occurring in between 15%-35% of cases. In a majority of these patients, their groin pain persisted after a previous hernia repair. The main type of chronic postsurgical pain is neuropathic, caused by injured nerves. One of the principal components in the pathophysiology of postsurgical pain is cytokines, specifically tumor necrosis factor (TNF). In animal studies, injecting TNF inhibitors before nerve injury can reduce pain behaviors and neuropathology. Finding a way to reduce the incidence of postsurgical pain after hernia repair could enhance function, and reduce the need for opioids and other analgesics. The investigators intend to conduct the first randomized, controlled study evaluating whether preemptive administration of a tumor necrosis inhibitor can reduce postoperative pain and opioid consumption after hernia repair. This is important because the degree and intensity of postsurgical pain is a major predictor for the development of chronic postsurgical pain.

Nalbuphine as an adjuvant to bupivacaine caudal anesthesia for postoperative analgesia in children undergoing Hypospadias repair. 2 groups, 30 patients each

Shoulder tip and abdominal pain following laparoscopic procedures are well recognized as causes of post-operative morbidity. This prospective, double-blind, randomized controlled trial attempts to reduce post-operative pain in patients undergoing laparoscopic surgery by implementing a simple intra-operative technique. Patients who undergo elective laparoscopic cholecystectomy for gallbladder disease or laparoscopic inguinal hernia repair will be recruited to the trial. Patients will be randomized to either the current standard (control group) or to receive an intervention to remove residual CO2. In the intervention group the pneumo-peritoneum will be removed, at the end of the operation, by placing the patient in the Trendelenburg position and utilising a pulmonary recruitment maneuver consisting of two manual inflations to a maximum pressure of 60 cm H2O. In the control group residual pneumo-peritoneum will be evacuated at the end of the procedure by passive decompression via the open operative ports.

In this randomized, controlled, observer-blinded study we plan to evaluate pain relief after ultrasound-guided transversus abdominis plane (TAP) block using bupivacaine and wound infiltration using liposomal bupivacaine in patients undergoing abdominal hysterectomy.

This study evaluates the effectiveness of a brief mindfulness-based intervention on post-operative pain and disability among anxious patients with chronic pain undergoing total hip arthroplasty. All participants will receive an educational brochure and links to videos containing strategies for coping with pain and anxiety. The half of the participants who are allocated to the treatment arm will also receive a 10 minute mindfulness intervention called a body scan.

This study represents a 3-arm, randomized controlled trial to investigate the impact of a validated 10-minute mindfulness intervention delivered via mobile technology on postoperative bariatric patients. The investigators hypothesize that participation in a brief, daily mindfulness intervention will improve outcomes in bariatric patients and use of mobile technology will facilitate patient compliance.

Currently, there are no studies that address the optimum dosage of lidocaine for surgical procedures. Lidocaine is a local anesthetic that is injected to induce anesthesia. Improper or inefficient pain treatment can lead to longer hospital stay, and adverse side effects such as nausea and vomiting. Opioids are the primary drug to treat moderate to severe pain, but are also responsible for nausea and other side effects. Lidocaine has shown to have opioid sparing effects; meaning less opioid use is necessary for pain relief. In this study, we will conduct a clinical trial to assess the difference between different lidocaine dosage schedules to determine the optimum dosage that brings maximum pain relief while minimizing adverse side effects and patient stay. A large benefit in using lidocaine is its documented opioid sparing which allows for minimal drug treatment.

This study would like to identify the best starting dose and infusion rate for nerve blocks and nerve catheters related to the erector spinae plane block that can improve functional status and pain control on cardiac surgery patients and minimize the necessity for opioid pain control using a continuous reassessment model.

Aim The general aim of this study is to improve post-operative pain and reduce morphine consumption following laparoscopic ventral hernia repair (LVHR). We specifically aim to conduct a randomized, double blinded, controlled trial to investigate the effect of intra-peritoneal local anaesthesia infusions on post-operative morphine consumption and. Methods: Patients will be randomised by computer generated random numbers (random permutation) and opaque envelope methods. At closure, one small 2mm catheter belonging to the AutoFuser pain pump system will be placed in the peritoneal cavity between the onlay mesh and parietal peritoneum. In the treatment arm patients will receive 275mL of 0.2% ropivacaine at 4mL/h. In the placebo arm, 275mL of 0.9% normal saline will be used in a similar fashion. The infusions will run for 68 hours total. All members involved in patient care (with the exception of one independant research fellow) will be blinded to the above. After 68 hours the pump will be stopped and the catheter will be removed. Assessment of post-operative pain will be performed by visual analogue scale, and total opiate consumption will be collected and converted into morphine equivalents. Health significance: Local anaesthesia has become an important addition to multimodal regimens of analgesia following surgery. Recent studies have shown that local anaesthetic (LA) wound infiltration has improved post-operative pain when compared with standard opioid regimens for pain relief. Only one previous study looked at bupivacaine infusions into the hernia sac for three days following LVHR. This study found no improvement in post-operative pain or morphine consumption. We aim to demonstrate improved pain and reduced morphine consumption using an alternative catheter insertion technique and ropivacaine as the desired LA agent.

The goals of this study are as follows: to confirm the safe dosing of ropivacaine for the erector spinae plane block develop a pharmacokinetic profile of the erector spinae plane block, which will help demonstrate how quickly and how closely toxic levels are reached when a routine dose of ropivacaine is given for this nerve block assess numbness created by the erector spinae block when routine doses are administered
