This article describes the rationale behind the use of systemically administered lidocaine as an analgesic. The analgesic efficacy of intravenously administered lidocaine is well documented by studies in human patients and laboratory animals. The mechanism by which systemically administered lidocaine produces analgesia is uncertain but is thought to include action at sodium, calcium, and potass...

Lidocaine was administered as a rapid intravenous bolus injection followed by a constant-rate intravenous infusion to nine dogs with 2-hour-old myocardial infarctions. Bipolar electrograms were recorded from and effective refractory periods were determined in the infarcted and normal zones of the heart. Intervals (Q-EG) were measured from the onset of the QRS complex in a standard electrocardio...

PURPOSE To evaluate the effect of local lidocaine application on the incidence of the oculocardiac reflex (OCR) during scleral buckling (SB) for rhegmatogenous retinal detachment (RRD) under general anesthesia. METHODS In a randomized clinical trial, eyes with RRD scheduled for SB under general anesthesia were randomized to adjunctive local application of 1 ml lidocaine 2% versus normal salin...

The effects of intravenous lidocaine on the refractory periods of the atrium, AV node and right ventricular myocardium were studied using His bundle recordings and the extrastimulus technique with and without atrial and ventricular pacing. The drug was administered in an intravenous bolus dose of 1 mg/Kg followed by an infusion of 100 micrograms/Kg/min. The AH, HV intervals and resting sinus cy...

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...

BACKGROUND The current randomized double-blind clinical trial aimed to compare the incidence of post-operative cough with intravenous vs. topical lidocaine in children with mild upper respiratory infection (URI) anesthetized with laryngeal mask airway (LMA) in the university-affiliated medical center. OBJECTIVES To assess the incidence of adverse respiratory event including cough, apnea, lary...
