OBJECTIVE The purpose of the study is to compare the effects of lidocaine alone, epinephrine-combined lidocaine and prilocaine with octapressin on the cardiovascular system during minor oral surgery of sedated cardiac dental patients under local anesthesia. METHODS Connected to a Holter electrocardiogram (ECG) monitor for a total of 5 hours starting 1 hour before the procedure, twenty patient...

OBJECTIVE To assess the hemodynamic and hemostatic effects of 2 different concentrations of epinephrine in local anesthetic used during functional endoscopic sinus surgery (FESS). Injection of local anesthetic containing epinephrine during endoscopic sinus surgery, while providing hemostasis, has been associated with cardiac adverse effects such as tachycardia, hypertension, as well as arrhythm...

BACKGROUND To investigate the mechanism by which rare cases of spinal local anesthetic (LA) neurotoxicity occur, we have tested the hypotheses that LAs elevate cytoplasmic calcium (Ca2+(cyt)), that this is associated with a neurotoxic effect, and that lidocaine and bupivacaine differ in their neurotoxicity. METHODS Neurons of the ND7 cell culture line, derived from dorsal root ganglion, were ...

Background. The purposes of the present investigation were 1) to track the incidence of primary ventricular fibrillation (VF) in the control and lidocaine-treated groups in the randomized control trials (RCTs) of lidocaine prophylaxis against primary VF in acute myocardial infarction, with particular emphasis on the time frame of the randomized trial, and 2) to estimate the number of patients w...

BACKGROUND Intravenous infusion of lidocaine decreases postoperative pain and speeds the return of bowel function. The authors therefore tested the hypothesis that perioperative lidocaine infusion facilitates acute rehabilitation protocol in patients undergoing laparoscopic colectomy. METHODS Forty patients scheduled to undergo laparoscopic colectomy were randomly allocated to receive intrave...

The aim of the study was to evaluate the effect of experimental diabetes on pharmacokinetic parameters of lidocaine and its metabolite monoethyl-glycylxylidide (MEGX) after a single intravenous administration in rats. The study was performed on male Wistar rats, randomized into 2 groups: group I--control animals and group II--animals with experimental diabetes induced by streptozotocin. Evaluat...

Recent clinical and experimental studies suggest the effectiveness of lidocaine in blocking neuropathic pain. Because it has been demonstrated that the pathogenetic mechanisms of neuropathic pain involve morphological changes in afferent neuronal terminals onto spinal cord, we examined the effects of lidocaine on neurite growth in isolated mouse dorsal root ganglion cells in culture. Incubation...

AIM The purpose of this study was to determine the anesthetic efficacy of inferior alveolar nerve block (IANB) using 4% articaine and 2% lidocaine supplemented with buccal infiltration. MATERIALS AND METHODS Forty five patients, diagnosed with irreversible pulpitis of a mandibular posterior tooth were included in the study. The first group of 15 patients received 2% lidocaine with 1:200000 ep...

Background: Duration of spinal anesthesia depends on the type of anesthetic agent, dosage and additive materials such as epinephrine, ephedrine and opioid. We compared the duration of spinal anesthesia with lidocaine 5% with or without epinephrine in addict and non-addict patients undergoing inferior limb fracture surgery. Methods: This single blinded randomized clinical trial was performed on ...
