Anti-Inflammatory Effect of Local Anaesthetic Ropivacaine in Lipopolysaccharide-Stimulated RAW264.7 Macrophages.

The present manuscript intended to investigate the anti-inflammatory effect of ropivacaine on lipopolysaccharide-induced inflammation in RAW 264.7 macrophages. Results suggested that ropivacaine causes significant inhibition of generation of nitric oxide (NO), prostaglandin E2, tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β, as well as expression of their synthesizing enzymes, inducible NO synthase, and cyclooxygenase-2. Moreover, ropivacaine causes inhibition of mitogen-activated protein ki...

Ropivacaine Protects against Memory Impairment and Hippocampal Damage in a Rat Neurodegeneration Model.

Ropivacaine, a long-acting amide local anesthetic agent, has been demonstrated to inhibit glutamatergic transmission. Glutamate neurotoxicity plays a pivotal role in the pathogenesis of brain disorders. The purpose of this study is to investigate the neuroprotective effect of ropivacaine against brain damage induced by kainic acid (KA), an analogue of glutamate.

Ropivacaine inhibits pressure-induced lung endothelial hyperpermeability in models of acute hypertension.

Increases in hydrostatic pressure results in endothelial hyperpermeability via eNOS-dependent pathways. Ropivacaine is known to inhibit eNOS activation and to attenuate lung injury. Herein, we sought to determine if ropivacaine regulates pressure-induced lung endothelial hyperpermeability.

Preclinical Studies of Ropivacaine Extended-Release from a Temperature Responsive Hydrogel for Prolonged Relief of Pain at Surgical Wound.

Postoperative pain is a common form of acute pain that has been treated commonly by local anesthetics through regional nerve blocking. In this study, a series of experiments were conducted using rats to investigate the pharmacokinetic, distribution, and efficacy of a temperature responsive hydrogel based drug delivery device (PF-72) containing ropivacaine (0.75%) for extended relief of postoperative pain by allowing prolonged release of ropivacaine. When the ropivacaine was administered using PF-72, its con...

Volume of ropivacaine 0.2% and common peroneal nerve block duration: a randomised, double-blind cohort trial in healthy volunteers.

The volume-duration relationship using low concentrations of ropivacaine for peripheral nerve blocks is unknown, even though low concentrations of ropivacaine are increasingly used clinically. We investigated the effect of ropivacaine 0.2% on common peroneal nerve block duration. With ethical committee approval, 60 consenting, healthy volunteers were randomly allocated to receive one of five volumes of ropivacaine 0.2% (2.5, 5.0, 10, 15 or 20 ml) administered by ultrasound-guided, catheter-based injection (...

Photoplethysmographic evaluation of sympathectomy during lumbar epidural analgesia: A randomized comparison of 0.125% ropivacaine and 0.125% levobupivacaine.

There are no data on the difference between the impact of ropivacaine and levobupivacaine on sympathetic nerve fibers during central neuraxial blocks. We hypothesized that there is no difference in the degree of sympathectomy between the two drugs during lumbar epidural analgesia for labor pain.

Serum ropivacaine levels after local infiltration analgesia during total knee arthroplasty with and without adductor canal block.

A common analgesic technique for total knee arthroplasty (TKA) is to inject local anesthetic into the periarticular tissue during surgery, known as local infiltration analgesia (LIA). Since the solution used typically contains a large amount of local anesthetic, concerns arise about exceeding the maximum dosage when adding a peripheral nerve block. Little research exists that addresses serum ropivacaine concentrations following LIA combined with peripheral nerve block. We hypothesized that after combining L...

Uterine contractility changes in a perfused swine uterus model induced by local anesthetics procaine, lidocaine, and ropivacaine.

Local anesthetics (LAs) are increasingly used as therapeutics due to their multiple molecular effects. They may be potential agents also in gynecology and reproductive medicine. The objective of this study was to investigate the contractility response of the perfused swine uterus to different concentrations of the LAs procaine, lidocaine, and ropivacaine.

Immediate postoperative pain control with ropivacaine following laparoscopic-assisted vaginal hysterectomy: A randomized double-blind pilot study.

Although laparoscopic hysterectomy, a worldwide popular surgery, ensures faster recovery and less postoperative pain than with laparotomic hysterectomy, immediate pain control still improving postoperative care. We introduce an effective method, intraoperative injection of ropivacaine into both uterosacral ligaments, to control immediate postoperative pain.

Effect of local anesthetic volume (20 mL vs 30 mL ropivacaine) on electromyography of the diaphragm and pulmonary function after ultrasound-guided supraclavicular brachial plexus block: a randomized controlled trial.

Diaphragmatic paralysis following supraclavicular brachial plexus block (SCBPB) is ascribed to phrenic nerve palsy. This study investigated the effect of 2 volumes of 0.375% ropivacaine on efficacy of block as a surgical anesthetic and as an analgesic and examined diaphragm compound muscle action potentials (CMAPs) and pulmonary function before and after SCBPB.

Surgical treatment of proximal femoral fractures in high-risk geriatric patients under peripheral regional anesthesia : A clinical case series.

The authors describe in a clinical case series (n = 7) of older (age 78-95 years) high-risk patients the successful surgical treatment of proximal femoral fractures in a peripheral regional anesthesia technique. After positioning on the non-fractured side, a double injection technique (dual guidance concept: sonography plus nerve stimulation) was chosen. The injections were performed parasacrally (blockade of the sacral plexus under the piriformis muscle) and lumbar-paravertebrally (psoas compartmen...

Brachial plexus block of the posterior and the lateral cord using ropivacaine 7.5 mg/mL.

We recently showed that the novel combination of a superficial cervical plexus block, a suprascapular nerve block, and the lateral sagittal infraclavicular brachial plexus block (LSIB) provides an alternative anaesthetic method for arthroscopic shoulder surgery. In this study, we hypothesised that the LSIB dose for this shoulder block could be significantly reduced by injecting only towards the shoulder relevant posterior and lateral cords. Our aim was to determine the minimum effective volume in 50% of the...

In vivo evaluation of post-operative pain reduction on rat model after implantation of intraperitoneal PET meshes functionalised with cyclodextrins and loaded with ropivacaine.

The avoidance of post-herniorrhaphy pain can be challenging for hernia repair and has the greatest impact on patient's quality of life, health care utilisation and cost to society. Visceral meshes, functionalised with an efficient drug carrier system - hydroxypropyl beta-cyclodextrin polymer (polyHPβCD) coating, were developed to give a prolonged intraperitoneal analgesic drug release. We attempted to evaluate the in vivo pain-relief efficacy of ropivacaine loaded polyHPβCD functionalised polyester meshe...

Effect of opioid-free anaesthesia on postoperative epidural ropivacaine requirement after thoracic surgery: a retrospective unmatched case-control study.

Introduction Patients undergoing thoracic surgery are at risk of severe postoperative pain. Post-thoracotomy pain relief is usually provided with thoracic epidural analgesia (TEA). Intraoperative use of opioids may result in hyperalgesia and increase analgesics consumption. We investigated the effect of opioid-free anaesthesia (OFA) on epidural ropivacaine requirement after thoracotomy. Methods This retrospective study compared postoperative epidural ropivacaine requirement of patients undergoing open thora...

The Amide Local Anesthetic Ropivacaine Attenuates Acute Rejection After Allogeneic Mouse Lung Transplantation.

Acute allograft rejection after lung transplantation remains an unsolved hurdle. The pathogenesis includes an inflammatory response during and after transplantation. Ropivacaine, an amide-linked local anesthetic, has been shown to attenuate lung injury due to its anti-inflammatory effects. We hypothesized that the drug would also be able to attenuate acute rejection (AR) after allogeneic lung transplantation.

The effect of hydromorphone as an adjuvant to ropivacaine in brachial plexus block.

Programmed Intermittent Bolus Regimen for Erector Spinae Plane Blocks in Children: A Retrospective Review of a Single-Institution Experience.

With few published reports on erector spinae plane block use in children, limited guidance on perioperative local anesthetic dosing exists. We present a series of 22 patients who received erector spinae plane catheters with programmed intermittent bolus for various surgeries. Median loading dose of 0.4 mL/kg (interquartile range [IQR], 0.1 mL/kg) ropivacaine 0.5%, intraoperative bolus of 0.3 mL/kg/h (IQR, 0.1 mL/kg) ropivacaine 0.2%, and a postoperative programmed intermittent bolus regimen of maximum 0.6 m...

To evaluate the effect of dexmedetomidine combined with ropivacaine on brachial plexus block in patients scheduled for elective shoulder arthroscopy.

A 96-hour continuous wound infiltration with ropivacaine reduces analgesic consumption after liver resection: A randomized, double-blind, controlled trial.

Continuous wound infiltration (CWI) with local anesthetics to reduce morphine consumption in postoperative pain management after open liver resection in patients with cancer.

A randomised trial of serratus anterior plane block for analgesia after thoracoscopic surgery.

We evaluated the effect of pre-operative serratus anterior plane block on postoperative pain and opioid consumption after thoracoscopic surgery. We randomly allocated 89 participants to block with 30 ml ropivacaine 0.375% (n = 44), or no block without placebo or sham procedure (n = 45). We analysed results from 42 participants in each group. Serratus anterior plane block reduced mean (SD) remifentanil dose during surgery, 0.12 (0.06) mg.h vs. 0.16 (0.06) mg.h , p = 0.016, and reduced mean (SD) fentanyl cons...

Antimicrobial Effect of Anesthetic-Eluting Ultra-High Molecular Weight Polyethylene for Post-Arthroplasty Antibacterial Prophylaxis.

Despite being a relatively safe surgery, total joint replacement is often associated with two major complications - severe post-operative pain and periprosthetic joint infection. Local sustained delivery of therapeutics to the surgical site has a potential to address these complications more effectively than current clinical approaches. Given that several analgesics were shown to possess antibacterial activity, we propose here to use analgesic-loaded ultra-high molecular weight polyethylene (UHMWPE) as a de...

Efficacy of Liposomal Bupivacaine Compared with Multimodal Periarticular Injections for Postoperative Pain Control following Total Knee Arthroplasty.

Single-dose long-acting periarticular anesthetics have been shown to be an effective method of postoperative analgesia in total knee arthroplasty (TKA). This study retrospectively compares the efficacy of multimodal periarticular injection consisting of a combination of ropivacaine, duramorph, epinephrine, and toradol (HC) with liposomal bupivacaine (LB) periarticular injection in TKA. This study was a retrospective matched comparative chart review of two cohorts of patients who underwent TKA within a singl...
