Objectives: In this clinical study hyperbaric ropivacaine in spinal anaesthesia for lower limb and hip surgery was evaluated and results obtained were compared with those using hyperbaric bupivacaine. Methodology: Two hundred patients scheduled for lower limb and hip surgery were randomly divided into two groups of 100 patients each. These patients received a spinal injection of either 3ml (15m...

Ropivacaine, a new, long-acting local anesthetic agent, has been shown to have beneficial effects in the treatment of ulcerative colitis. Treatment with this drug results in prompt symptomatic relief. The aim of this study was to examine the effects of ropivacaine on mucosal healing and to investigate whether ropivacaine can restore the decreased colonic contractility seen in the diseased state...

Background: Arthroscopic shoulder surgery can result in severe postoperative pain. A variety of methods have been used to control pain in postoperative period and the results are variable. The purpose of this study was to compare the relative analgesic efficacies of the postoperative intraarticular infusion of ropivacaine, ropivacaine/fentanyl, and ropivacaine/fentanyl/ketorolac after arthrosco...

BACKGROUND AND OBJECTIVES Peribulbar anesthesia can reduce ocular blood flow (OBF) by increasing intraocular pressure (IOP) or due to the action of drugs. Ropivacaine has low toxicity and intrinsic vasoconstrictive properties, yet to be proven on the ocular vasculature. Measurements of ocular pulse amplitude (OPA) allow the indirect evaluation of the OBF. The objective of the present study was ...

We encountered cardiac arrest induced by 0.375 % ropivacaine 7 ml administered via a catheter for continuous thoracic paravertebral block (TPVB) in a 6-year-old female who underwent pacemaker implantation for sick sinus syndrome (SSS). She was successfully resuscitated with adrenaline and lipid emulsion. Plasma concentration of ropivacaine was 5.2 μg/ml, suggesting intravascular administration ...

Ropivacaine is a new aminoamide local anaesthetic. Compared with bupivacaine, ropivacaine possesses a higher threshold for systemic toxicity and a high selectivity for sensory fibres. We have compared prospectively these two agents in a concentration of 0.25% for extradural analgesia in labour. A total of 104 parturients requesting extradural analgesia were randomized to receive either ropivaca...

INTRODUCTION Local anesthetic infusion techniques have been reported to reduce opiate requirements and pain scores following different kinds of surgery, including orthopedic surgery, inguinal hernia, and Cesarean surgery in women. METHODS PRF-108 and PRF-110 formulations were applied to the wound space in an incisional model in pigs to test the hypothesis that these formulations have better a...

We have compared the quality of three regimens of postoperative analgesia (continuous epidural administration of ropivacaine (Ropi. group), epidural ropivacaine and patient-controlled analgesia (PCA) with i.v. morphine (Ropi. + PCA group) and PCA morphine alone (PCA group)) during the first postoperative 24 h in a multicentre, randomized, prospective study. Postoperative analgesia was studied i...

BACKGROUND Despite the widespread clinical application of ropivacaine, there is little information on the cellular cardiac effects of the drug. In the current study, therefore, the concentration-dependent effects of ropivacaine on action potential morphology and the underlying ion currents were studied and compared with those of bupivacaine in isolated canine ventricular cardiomyocytes. METHO...

To the Editor: We report the unintentional administration of 400 mg ropivacaine during an interscalenic block in a patient suffering from hemolytic-uremic syndrome and epilepsy. The patient was scheduled for the creation of an arterio-venous fistula of the left forearm. The interscalenic block was performed with a neurostimulator and 400 mg ropivacaine (6.15 mg·kg–1), instead of the intended 20...
