Local anesthetics are the most commonly used drugs in dentistry. This article provides a brief update on the pharmacology, adverse effects and clinical applications of these drugs, as well as the role of vasoconstrictors.
Introduction. Intradialytic hypotension (IDH) is a common complication during hemodialysis which may increase mortality risks. Low dose of Korean red ginseng (KRG) has been reported to increase blood pressure. Whether KRG can improve hemodynamic stability during hemodialysis has not been examined. Methods. The 8-week study consisted of two phases: observation phase and active treatment phase. A...
BACKGROUND It was the aim of this study to elucidate the influence of opioids on coronary vascular tone using the model of isolated porcine coronary artery segments. METHODS We studied the effects of fentanyl (0.01, 0.1, 1.0 microg ml(-1)), alfentanil (0.1, 1.0, 10 microg ml(-1)), and sufentanil (0.01, 0.1, 1.0 microg ml(-1)) on the contractile response to three vasoconstrictors, acetylcholin...
OBJECTIVE The objective of this study is to systematically review the literature and examine the safety for the use of topical vasoconstrictors in endoscopic sinus surgery. STUDY DESIGN Systematic review clinical trials. METHOD A systematic literature search was performed in MEDLINE, EMBASE, The Cochrane Library, and National Guideline Clearinghouse, and references in the selected articles....
The association of a vasoconstrictor with a local anaesthetic solution is indicated because the vasoconstrictor decreases the intravascular passage of the injected solution and thus ensures an increase in duration and depth of the anaesthesia while reducing the systemic effects of the solution. Adrenaline is the main vasoconstrictor used today in local anaesthesia for dental treatments as it pr...
