Active clinical trials for "Pain, Postoperative"

A revised ultrasound-guided approach to the lumbar plexus is investigated as for efficacy and safety in elderly trauma patients undergoing operations of the lower extremeties.

The rationale for multimodal analgesia is to achieve additive or synergistic analgesic properties while decreasing the incidence of side effects by reducing the dose of each agent. Nociceptive stimuli are known to activate the release of the excitatory amino acid glutamate in the dorsal horn of the spinal cord. The resultant activation of NMDA receptors causes calcium entry into the cell and triggers central sensitization. This mechanism is involved in the perception of pain and mainly accounts for its persistence during the postoperative period. Peri-incisional injection of local anesthetics is an effective method for pain relief after many surgical procedures, as it can reduce postoperative analgesic consumption. Ropivacaine is a propyl analog of bupivacaine with a longer duration of action with a much safer cardiotoxicity profile than bupivacaine. Thus, a combination of local anesthetic with other analgesic factors, such as opioids, dexmedetomidine, clonidine, ketamine, magnesium sulfate, dexamethasone is suggested for a better analgesic outcome. Dexmedetomidine, a highly selective a2-adrenergic receptor agonist, has been the focus of interest for its broad spectrum (sedative, analgesic, and anesthetic sparing) properties, making it a useful and safe adjunct in many clinical applications. The intravenous, intramuscular, intrathecal, epidural, and perineural use of this agent enhances analgesic effects. Tramadol hydrochloride is a synthetic analog of codeine that acts on both opioid (weak m receptor agonist) and nonopioid receptors (inhibits the reuptake of noradrenaline and serotonin as well as release stored serotonin from nerve endings) which play a crucial role in pain inhibition pathway. It also blocks nerve conduction which imparts its local anesthetics like action on peripheral nerves. It was reported that NMDA antagonists could prolong the analgesic effect of bupivacaine to even a week, as well as inhibit hyperalgesia. Magnesium sulfate (MGS) is a non-competitive antagonist of N-methyl, D-aspartate (NMDA) receptors with an analgesic effect and is essential for the release of acetylcholine from the presynaptic terminals and, similar to calcium channel blockers (CCB), can prevent the entry of calcium into the cell. Aim of the study is to evaluate and compare the postoperative analgesic efficacy of tramadol, dexmedetomidine, and magnesium when added to ropivacaine as an adjuvant for wound infiltration following spine surgery.

Aim: This study aims to assess the effect of root canal disinfection with a 980 µm diode laser following chemomechanical root canal preparation on the severity of pain after root canal treatment (RCT). Materials and Methods: In present study, asymptomatic, single-rooted teeth with periapical index (PAI) score 3 or 4 were included. All patients were treated with two visits of root canal treatment including dressing with calcium hydroxide. Patients were randomly divided into two groups (n: 28). 'Control (no laser)': The final irrigation was performed using 5ml 2.5% NaOCI, followed by 5 ml 17% EDTA and 5 ml distilled water. 'Laser Disinfection (LD)': Root canals were irradiated with 980 µm diode laser after final irrigation at both visits. The pain levels were evaluated using visual analog scale (VAS) after 8, 24, 48 hours and 7 days. In addition, analgesic intake and time intervals were recorded by patients. The collected data were statistically analyzed with the Chi-square and Mann-Whitney U test (p<0.05).

The role of a single-dose intraoperative methadone on postoperative pain and opioid consumption in patients undergoing Surgeon Accuracy Robot Assistant cystectomy. A prospective double-blind, randomized controlled trial investigating the effect of a single-dose of intraoperative methadone in patients undergoing robotassisted cystectomy.

The purpose of this study is to compare the postoperative pain and other clinical outcomes in patients who, during bariatric surgery, will be injected with a local anesthetic (Ropivacaine) through two different techniques.

This prospective, randomized, double-blinded study is designed to evaluate the postoperative analgesic effect of the continuous infusion of intravenous nefopam in patients undergoing video-assisted thoracic surgery (VATS). We hypothesize that the continuous infusion of intravenous nefopam can significantly reduce postoperative opioid consumption and pain severity in patients with VATS.

A hundred twenty patients who had an asymptomatic mandibular molar teeth with periapical lesion were included. For each patient, teeth were prepared with Reciproc Blue or Protaper Universal instruments. Each tooth was obturated with gutta-percha and resin-based sealer using single cone technique for mesial roots and for distal roots single cone and cold lateral compaction technique. Root canal treatment was performed in a single visit. Postoperative pain was assessed as no, mild, moderate, or severe at 6, 12, 24, 48, 72 hours and 7 days after obturation.

This randomized, double-blinded, placebo-controlled trial seeks to evaluate the analgesic efficacy of the pericapsular nerve group block in the setting of outpatient hip arthroscopy.

This paucity of evidence supporting or dissuading the use of postoperative abdominal support following cesarean section for the reduction of postoperative pain leaves important clinical questions unanswered. Additionally, there is an absence of long-term outcomes associated with the use of abdominal support devices. There remains a need for the development and implementation of nonpharmacologic methods for analgesia for women following cesarean sections, along with evidence-based recommendations regarding their use in postoperative patients. The ABBy (G-Squared Medical, Brentwood, TN) is an extended-wear panniculus retractor/tissue stabilizer that is intended for use postoperatively after abdominal procedure. It is placed directly onto patient skin, superior to a transverse incision, and is then used to elevate redundant tissues away from an incision or wound (https://www.gsquaredmedical.com/How-it-Works.html). The ABBy can be removed and replaced by patients and can be used for up to 10 days. This study aims to assess the effect of ABBy use on postoperative pain, pain medication requirement, and patient satisfaction, when used as a patient-positioning device in women following cesarean delivery.

A clinical trial investigating the effect of a combined locoregional anesthesia technique on the postoperative analgesia outcomes after a total hip arthroplasty. A PENG block will be used in combination with a LFCN block. The results will be compared to a control group that is solely treated with intravenous analgesia. This technique aims to provide improved pain scores after surgery without interference of revalidation.
