BACKGROUND The analgesic effect of perioperative low doses of intravenous lidocaine has been demonstrated after abdominal surgery. This study aimed to evaluate whether a continuous intravenous low-dose lidocaine infusion reduced postoperative pain and modified nociceptive pain threshold after total hip arthroplasty. METHODS Sixty patients participated in this randomized double-blinded study. ...
BACKGROUND One-per-mil tumescent solution, which contains 0.2% lidocaine with 1:1,000,000 epinephrine, has been reported to be clinically effective for hand surgery under local anesthesia. However, it was lacking in its basic pharmacokinetics profile in regard to the onset of action (OOA) and duration of action (DOA). METHODS A randomized, double-blind study was conducted on 12 volunteers who...
AIMS In spastic subjects, lidocaine is often used to induce a block predictive of the result provided by subsequent surgery. Lidocaine has been demonstrated to inhibit the Hoffmann (H) reflex to a greater extent than the direct motor (M) response induced by electrical stimulation, but the timecourse of these responses has not been investigated. METHODS An animal (rat) model of the effects of ...
A neutral mononuclear Fe(II) complex with spin crossover (SCO) properties, Fe2(SCN)2 (1) (L = 2-(2-(trifluoromethyl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline), was solvothermally synthesized. It displays a new example of two-step SCO with Tc1↓ = 250 K, Tc1↑ = 260 K and Tc2 = 295 K.
background there have been many concerns about alteration in hemodynamic parameters within and shortly after endotracheal intubation (eti) in patients scheduled for elective coronary artery bypass grafting (cabg). objectives we compared the attenuation effect of magnesium sulfate and lidocaine on hemodynamic responses after eti, in patients undergoing cabg. patients and methods in this randomiz...
BACKGROUND Adding epinephrine to lidocaine solutions for peripheral nerve block potentiates and prolongs the action, but by incompletely understood mechanisms. In an effort to discriminate the pharmacokinetic from the pharmacodynamic effects of epinephrine, the authors measured the lidocaine content of peripheral nerve over the course of block produced by 0.5% lidocaine, with and without epinep...
STUDY OBJECTIVE To compare pain on infiltration, need for additional anesthesia, and pain on suturing in patients given plain, warm, and buffered lidocaine preparations before the suturing of traumatic wounds in the emergency department. DESIGN Randomized, prospective, single-blinded convenience sample. SETTING University hospital ED. PARTICIPANTS Patients with traumatic lacerations. Pati...
BACKGROUND Lidocaine has been used widely to prevent propofol injection pain. Various methods of administration exist, such as lidocaine premixed with propofol or lidocaine pretreatment using a tourniquet, but it is unclear which method of lidocaine administration is more effective for the prevention of injection pain of propofol LCT/MCT. The purpose of this study was to compare pretreatment of...
Phentolamine mesylate accelerates recovery from oral soft tissue anesthesia in patients who have received local anesthetic injections containing a vasoconstrictor. The proposed mechanism is that phentolamine, an alpha-adrenergic antagonist, blocks the vasoconstriction associated with the epinephrine used in dental anesthetic formulations, thus enhancing the systemic absorption of the local anes...
Background & Aims: In general anesthesia, patients’ coughing during and after recovery is an important clinical problem with a prevalence of 15% to 45%. This study aimed to evaluate the effects of alkalinized lidocaine or lidocaine alone into the tracheal tube cuff on post-extubation cough in lumbar laminectomy surgery with general anesthesia. Materials & Methods: Ninety patients ...
