Active clinical trials for "Pain, Postoperative"

Post operative pain after open heart surgery is still a main concern; current multimodal analgesia modalities have shown good efficacy for postoperative pain at rest, without reaching full pain relief. The primary goal of this study is to evaluate the effectiveness of peri-operative analgesia, measured by consumption of opioids during the first 48h hours after the surgery, using bilateral erector spinae catheters for 48h, compared to single shot erector spinae block in pediatric patients undergoing open heart surgeries .

Patients with kidney cancer often undergo hand-assisted laparoscopic nephrectomy or Robot assisted partiel nephrectomy. The investigators performed a one-year retrospective study. the sudy revealed that 67% of the patients needed substantial amounts of opioids for postoperative pain management (PPM) in recovery despite a multimodal analgesic regime. In a prospective pilot study including ten laparoscopic hand-assisted nephrectomy, with severe postoperative pain the investigators found that bilateral Ultrasound-guided (USG) transmuscular quadratus lumborum (TQL) block substantially reduced pain and opioid consumption. This study aims to evaluate the effect on PPM of a bilateral USG TQL block compared to placebo.

A prospective, double-blinded randomized controlled, 1-year follow-up study was designed to compare the analgesic effect of serratus plane block (SPB) after breast cancer surgery. Women undergoing radical mastectomy were dIvided into Control group and SPB group. The postoperative acute pain was evaluated by numerical rating scale (NRS) and the effect of preventing chronic pain was assessed at 3, 6, 12 months after surgery by NRS.

Spinal cord stimulation (SCS) is a widely applied therapy to treat chronic neuropathic pain, and one of the most common indications is persisting radicular neuropathic pain following lumbar spine surgery. In traditional SCS therapies, the objective has been to replace the pain sensation with paresthesia. The anticipation is that the electrical current alters pain processing by masking the sensation of pain with a comfortable tingling or paresthesia. Although patients mostly cope with paresthesia, a significant proportion reports that the sensation is unpleasant. 'Burst' SCS utilizes complex programming to deliver high-frequency stimuli. This SCS technique seems to provide paresthesia-free stimulation, resulting in better pain relief of low back and leg pain then traditional tonic stimulation. The widespread use of SCS has not been backed by solid evidence. The absence of placebo-controlled trials has long been an important point of criticism, but due to the nature of the intervention with sensation of paresthesia, studies with placebo control have so far not been considered possible. When 'burst' SCS is used the stimulation is often unnoticed by the patient, allowing comparison with placebo stimulation. The aim of this randomized double-blind sham-controlled crossover trial is to evaluate the efficacy of 'burst' spinal cord stimulation for chronic radicular pain following spine surgery.

A randomized prospective trial to assess whether the use of loco regional anesthesia as adjuvant analgesic therapy is more effective of intravenous analgesia only.

This is a Phase 3, randomized, double-blind, controlled, parallel-group, multicenter clinical trial with co-crystal E-58425 compared to tramadol, to celecoxib, and to placebo. The primary objective of the trial is to establish the analgesic efficacy of co-crystal E-58425 by demonstrating a superior effect compared to tramadol and to celecoxib for the management of moderate to severe acute post-operative pain for 48 hours after bunionectomy.

Aim of the study To investigate whether auricular acupuncture (AA) will reduce postoperative pain and analgesic requirement in comparison with sham AA in patients after elective knee arthroplasty Design Prospective randomized controlled blinded clinical trial Participants: Patients < 80 und > 50 years old scheduled for knee arthroplasty under general anesthesia with < 120 minutes duration Without previous opioid medication Able to give informed consent Outcome measures Postoperative analgesic requirement Incidence of side effects Physiological parameters

This study evaluates a Ropivacaine 0.2% Pre-Filled Dispenser in the treatment of post-surgical pain in patients undergoing Cesarean delivery. Half of the patients will receive Ropivicaine and half will receive placebo.

To study the multimodal protocol combining adjunct ketamine with oxycodone in intravenous patient-controlled analgesia bolus dosing and effects in patients scheduled for posterolateral lumbar spine fusion with bilateral transpedicular screw instrumentation

Patients undergoing Primary Total Knee Arthroplasty will be randomized to receive either multimodal single injection adductor canal block with sham infusion catheter or continuous infusion of local anesthetic (control) for postoperative analgesia. Primary end point is pain scores at 30 hours post performance of block procedure.
