Active clinical trials for "Pain, Postoperative"

With this pilot investigation, the investigators aim to challenge the reliance on opiate analgesia following colon and rectal surgery. Narcotic misuse and abuse is a pressing public health concern, and reduction in prescription rates could help to mitigate this issue. The goal of this pilot study is to establish feasibility of sufficient post-operative pain control after colectomy using non-narcotic analgesics. The investigators hypothesize that patients will be able to manage their post-operative pain without narcotic intervention, while minimizing side effects and complications. This initial pilot study will provide proof-of-concept for a larger, randomized investigation on non-narcotic analgesia after colectomy.

Primary knee arthroplasty by total prosthesis is a painful surgery, performed on patients with advanced gonarthrosis (stage III), thus already presenting hyperalgesia and hyperalgesia and allodynia. This terrain makes the risk of postoperative hyperalgesia but also of persistent postoperative risk of persistent post-surgical pain. Nefopam is a non-opioid centrally acting analgesic drug used as a part of multimodal analgesia. The opioid-sparing effect of nefopam is still controversial across various surgical procedures. In France nefopam is only available as a parenteral formulation; however it is often administered orally. There is currently no study addressing the efficacy of oral nefopam for the postoperative pain management including pain prevention. The investigators conduct a prospective, double-blinded randomized controlled study with the main objective to examine the effect of perioperative orally administered nefopam on postoperative pain after a total knee arthroplasty. Secondary objectives include the quantification of wound allodynia, analysis of adverse events, clinical outcomes, and a pharmacokinetic study of orally given nefopam (plasma and cerebrospinal fluid dosage).

A Randomized, Placebo-Controlled Study to Evaluate the Efficacy of Perioperative Dextromethorphan compared to Placebo for the Treatment of Postoperative Pain

Overall Aim: To evaluate the efficacy of continuous erector spinae block (ESB) versus continuous paravertebral block (PVB) for postoperative analgesia in children and adolescents undergoing surgical procedures via unilateral thoracotomy. Hypothesis: The investigators hypothesize that ESP block efficacy is not inferior to that of PVB with respect to pain control and consumed opiate equivalents at 24 hours postoperatively.

The introduction of Acute Pain Service (APS), 1985, specialized pain management could be offered to the inpatient care. An example of this is patient-controlled analgesia (PCA), which is a technique that is used mostly after surgery. A PCA pump is an electronic pump that is prepared with pain relief medicine, usually an opioid, which is administered either epidural or intravenously. PCA pumps are programmed with medical protocols. For prevent overdose, there are blocking times between possible bolus doses and a maximum dose per hour. In a Cochrane review from 2015, PCA have shown to be more beneficial for the patient especially when it comes to patient satisfaction, compared to conventional pain relief where nurses administer pain relief on request. The authors could also demonstrate that patients experience less pain and were more satisfied with patient-controlled analgesia. However, studies have showing limitations in the ease of practice of the PCA pumps, which indicates need for further development. Today the major part of the documentation in the Swedish healthcare is computerized. Using digital systems that communicate with each other should be seen as a matter of course. Instead, a human intermediator is commonly used where documentation is performed by pencil and paper. Due to the human factor that may affect the interpretation of the information the patient safety is placed at risk. The elimination of the human intermediator could lead to a safer transfer of information. There are already studies concerning computerized PCA pumps and wireless communication by medical devices, but only studies that are conducted outside of Europe and studies with the technical aspect in focus. Studies have shown that wireless communication by medical devices in the nursing setting can provide support for prioritization and increase the patient safety. However, the field of research lacks of knowledge when it comes to the patients' and nurses' experience of using PCA pumps with wireless communication system. Due to today's research field, further studies will be needed to investigate how documentation can be safeguarded and how accessible information regarding patients' need for pain relief can be linked to prescribed treatment. This may also lead to the development of nurses' way of work with patient-controlled and epidural pain relief in the postoperative pain management.

Title: A prospective randomized double blind trial of the efficacy of a bilateral lumbar erector spinae block on the 24 h morphine consumption after posterior lumbar interbody fusion surgery. Objectives: The primary objective is to study the influence of a bilateral erector spinae block on 24h morphine consumption. Endpoint: The primary endpoint is the 24 h morphine consumption in mg. Secondary endpoints are intraoperative sufentanil requirement, total morphine during first 72 postoperative hours, NRS pain scores in rest and defined movement (moving to chair) at regular time intervals and Quality of Recovery 40 score (QoR-40) at fixed time intervals day 1 and 3 postoperatively Population: Patients undergoing posterior lumbar interbody fusion ranging 1 - 3 levels Phase 3 Number of sites Enrolling participants: University Hospital Antwerp &AZ KLINA Brasschaat Description of study agent: Bilateral erector spinae block: each block contains 20 ml levobupivacaine 0.25% + 5 mcg/ml epinephrine Study duration Until the required study population is met Participant duration 72 hours

This study is a comparison of the analgesic efficacy of transversus abdominis plane (TAP) blocks with ropivacaine bolus plus continuous ropivacaine infusion via catheters versus single shot TAP blocks with liposomal bupivacaine.

Trial name: DEXRAR: Dexamethasone in revision arthroplasty: A randomised, blinded, 2-group clinical trial Trial acronym: DEXRAR Background: Effective postoperative pain management is essential for the well-being and rehabilitation of the surgical patient. No "gold standard" exists for pain treatment after revision total knee arthroplasty (TKA) and combinations of different medications are used with virtually no evidence for combined analgesic efficacy. Objectives: The objective is to investigate the analgesic effect and safety of dexamethasone as a single dose after revision-TKA in combination with paracetamol, ibuprofen and local infiltration analgesia Intervention: The patients are randomised into to groups: A) 24 mg dexamethasone i.v. B) isotonic saline i.v. Design and trial size: Placebo controlled, parallel 2-group trial with adequate centralised computer-generated allocation sequence and allocation concealment with block size of 12. Blinding of assessor, investigator, caregivers and patients. Sample size: 108 eligible patients are needed to detect a difference of 11,3 mg morphine for the first 24 h postoperatively with a standard deviation of 20 mg, a type 1 error rate of 0,05 and a type 2 error rate of 0,20.

The purpose of the trial is to identify the "most simple non-inferior of three different methods", placebo, laparoscopic assisted transverse abdominal plane block (L-TAP) and ultrasound guided TAP block (US-TAP), using postoperative opioid consumption as a measure of efficacy in patients undergoing elective minimally invasive colon surgery in an ERAS setting. Postoperative pain scores and length of stay (LOS) will also be measured. The simplicity of the three methods is ranked as: 1) placebo, 2) L-TAP and 3) US-TAP.

This study proposes to evaluate the efficacy of single shot erector spinae block (ESB) versus single shot quadratus lumborum block (QLB) when used in conjunction with continuous lumbar plexus block (LPB) for postoperative analgesia in children and adolescents undergoing unilateral hip surgical procedures. The aim of this study is to compare the efficacy of the QL vs. ESP blocks as supplements to the lumbar plexus block with respect to pain control outcomes after hip PAO surgery. Both blocks are safe and easy to perform. There is currently no comparative, prospective data concerning the use of these two blocks for hip surgery. The investigational hypothesis is that there will be no clinical difference in the amount of opioid consumed or the overall pain control offered by these two block options.
