PURPOSE To evaluate the effect of nitroglycerine (NTG) on sensory and motor block onset and recovery time as well as the quality of tourniquet pain relief, when added to lidocaine (LID) for intravenous regional anesthesia in elective forearm and hand surgery. METHODS A randomized double-blinded clinical trial was performed on 40 patients that were randomly allocated into two groups received l...

Introduction: Success in anesthesia administration relieves the perception of pain during surgery. Lidocaine is the most commonly used local anesthetic agent in clinical medicine. Moreover, anesthetic agents' temperature changes can influence cell membrane permeability. Here, the effectiveness of different temperatures of lidocaine (Lid.) on anesthesia success rate in rats has been investigated...

LID retraction and lid lag in thyrotoxicosis have been diminished by intramuscular reserpine (Canary, 1957), oral guanethidine (Waldstein, West, Lee, and Bronsky, 1964), and oral propranolol (Buckfield and Davis, 1966), while the increasing availability of local ophthalmic preparations of adrenergic blocking agents has resulted in the local use of propranolol (Sneddon and Turner, 1966), phentol...

A double blind, prospective study was undertaken to compare aqueous humour penetration of topical 0.3% norfloxacin and 0.3% ciprofloxacin and their effect upon normal eyelid flora in 39 patients undergoing cataract surgery. Lid swabs were taken before and after six 1 hourly applications of single drops of ciprofloxacin or norfloxacin given before surgery. Aqueous humour was aspirated at surgery...

In this paper, we introduced a numerical analysis for the effect of magnetic field on mixed convection and heat transfer inside two-sided lid-driven cavity with convective boundary conditions its adjacent walls under effects presence thermal dispersion partial slip. A single-phase model in which water is base fluid copper nanoparticles assumed to represent nanofluid. The bottom top move horizon...

Numerical simulation of the bifurcation of Bingham fluid streamline topologies in rectangular double-lid-driven cavity, with varying aspect (height to width) ratio A, is presented. The lids on the top and bottom move at the same speed but in opposite directions so that symmetric flow patterns are generated. Similar to the Newtonian case, bifurcations occur as the aspect ratio decreases. Special...

Low-impact development (LID) practices as a new approach to urban stormwater management have demonstrated their positive effects through the reduction of surface runoff volumes and pollutant loadings in a substantial amount of research. The effectiveness of LID practices can be affected by various LID conditions such as type, location, and area. Cost is also an important factor to be considered...
