OBJECTIVES To evaluate through the visual analog scale (VAS) the pain in patients undergoing total knee replacement (TKR) with different pressures of the pneumatic tourniquet. METHODS An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures ...

The wide awake approach to hand surgery means that the patient is unsedated for up to 95% of all hand surgery procedures. For the patient, the experience is reduced to the equivalent of a visit to the dentist where no preoperative tests are required, only lidocaine with epinephrine is injected, and where they get up and go directly home after the procedure.1 This is made possible by the recent ...

OBJECTIVE The goal of the study was to investigate the regional intravenous anesthesia procedure in knee arthroscopy and to evaluate the effects of adding ketamine over the anesthesia block charactery and tourniquet pain. MATERIAL/METHOD Forty American Society of Anesthesiologists (ASA) II patients who received knee arthroscopy were enrolled. After monitoring, a peripheral IV line was inserte...

STUDY OBJECTIVE To compare the anesthetic effects of two different concentrations and doses of ropivacaine (0.2% and 0.25%) with those of a conventional dose of lidocaine 0.5%. DESIGN Prospective, randomized, double-blinded, clinical investigation. SETTING Large metropolitan university hospital. PATIENTS 66 adult ASA physical status I and II patients undergoing forearm and hand surgery. ...

Background: Ropivacaine for intravenous regional anesthesia (IVRA) provides prolonged analgesia over lidocaine and have a lower toxicity compared with bupivacaine. To reduce the amount of local anesthetic and to improve the quality of the block additives like opioids are used. Aim: The present study was designed to assess the anesthetic efficacy and post-tourniquet analgesia of adding fentanyl ...

Perioperative nurses are likely to encounter the use of pneumatic tourniquets in a variety of operative and invasive extremity procedures. Use of a pneumatic tourniquet offers an opportunity to obtain a near-bloodless surgical field; however, the use of tourniquets is not without risk. Unfavorable outcomes include pain, thrombotic events, nerve compression injuries, and disruption of skin integ...

Methods. Randomly assigned patients awaiting elective surgery received a communication immediately before i.v. cannulation consisting of either ‘I am going to apply the tourniquet and insert the needle in a few moments. It’s a sharp scratch and it may sting a little’ (Group S) or ‘I am going to apply the tourniquet on the arm. As I do this many people find the arm becomes heavy, numb and tingly...

In order to assess the effect of spinal clonidine on tourniquet pain, 30 patients scheduled to undergo orthopaedic surgery under spinal anaesthesia were allocated randomly to two groups. Patients in group I (n = 15) received 0.5% isobaric bupivacaine 15 mg plus isotonic saline 1 ml. Patients in group II (n = 15) received 0.5% bupivacaine 15 mg plus clonidine 1 ml (150 micrograms). Sensory block...

BACKGROUND A microemulsion propofol causes a high incidence of pain during intravenous injection. In this study, we investigated the effect of ramosetron on pain induced by microemulsion propofol injection. METHODS After prospective power analysis and institutional review board approval, a total of 200 ASA I and II patients undergoing general anesthesia were divided into 4 groups. They receiv...

introduction: ischaemic-reperfusion nerve injury has been suggested as the mechanism for post-tourniquet limb paralysis. as dexamethasone (dex) has been shown to prevent ischaemic-reperfusion process in some tissues, we tested the hypothesis that this drug would reduce tourniquet induced nerve injury. methods: 36 male wistar rats (200-250 gr) were chosen and divided randomly into 6 equal groups...
