AIMS To determine the relation between pH of anaesthetic solutions and patient perception of pain with peribulbar injection of local anaesthesia. METHODS This prospective randomised controlled double blind pilot study involved 60 consecutive patients who received a peribulbar block with either a standard acidic local anaesthetic of 5 ml 2% lignocaine and 5 ml of 0.5% bupivacaine (solution A),...

Purpose: To evaluate and compare the effects of topical application and subconjunctival injection of bevacizumab on corneal neovascularization (CNV) in rabbits' eyes after chemical burning of the cornea. Methods: The animals were randomly distributed into four groups of five animals. In one group, the drug was instilled, while in another, it was administered by subconjunctival injection. The ...

The ability of ammonia to act as a hydrogen carrier, without the drawbacks gas-storage costs and low stability-renders it potential solution decarbonisation transport. This study combines both modelling experimental techniques determine effect varying degree aspiration ammonium hydroxide (NH4OH) solution, at different engine loads, in combustion compression ignition engine. Ignition delay was e...

Ketamine hydrochloride for injection is a rapid-acting general anesthetic agent. To avoid an out-of-stock situation for this drug at the desired concentration for administration to patients (10 mg/mL), the author’s institution investigated the chemical stability of a diluted solution of the concentrated formulation (50 mg/mL), packaged for storage in glass vials. The only difference between the...

Start of fuel injection and fuel type are two important factors affecting engine performance and exhaust emissions in internal combustion engines. In the present study, a one-dimensional computational fluid dynamics solution with GT-Power software is used to simulate a six-cylinder diesel engine to study the performance and exhaust emissions with different injection timing and alternative fuels...

A problem of current interest in geothermal energy extraction is the injection of cold water into a porous medium containing superheated vapor. Such injection will cause a boiling front to move away from the injection point. When flow is approximated as being one-dimensional radial, it can be shown from similarity variable concepts that temperature, pressure, and boiling rate at the front are c...

Ficuax 1. Two-dimensional echocardiogram stop frame images are shown above and accompanying schematics below. Left panel demonstrates an apical image with four heart chambers. Middle panel shows cloud of echoes from peripheral injection of normal saline solution demonstrating simultaneous appearance of echoes in all four chambers. A similar injection postoperatively demonstrates echoes in right...

Statement of the Problem Dental injection is one of the most fearful procedures in dental setting, especially for children. Many researchers have attempted to find a painless method. As computer controlled local anesthesia delivery system devices (CCLADs) allow the speed rate and pressure of injection solution to be controlled, they may cause less pain during injection in comparison to the conv...

The petroleum product has seen a drastic demand in the recent past. Biofuels are the only solution to overcome this power crisis. In the view of sustainable energy development, biodiesel and its additives have become the best options for fossil fuel-based engines. In this work, a biodiesel mix was used to show the possible utilization of different biofuels. An experimental investigation was car...
