BASIC EXPERIMENTS ON INTRAOSSEOUS INJECTION

Lithium Pellet Injection Experiments

A pellet enhanced performance (PEP) mode, showing significantly reduced core transport, is regularly obtained after the injection of deeply penetrating lithium pellets into Alcator C-Mod discharges. These transient modes, which typically persist about two energy confinement times, are characterized by a steep pressure gradient (4, <a/5) in the inner third of the plasma, indicating the presence ...

Intraosseous injection for profound anesthesia of the lower molar.

The endodontic treatment of mandibular molars is complicated when block anesthesia is less than tolally effective. Supplemental anesthesia by infiltration gives little or no additional effect because of the thickness of the buccal or lingual bone in this area. Other methods for obtaining profound anesthesia must be attempted, unless the patient and the dentist agree to the unpleasantness of a p...

Flatland optics. II. Basic experiments.

In "Flatland optics: fundamentals" [J. Opt. Soc. Am. A 17, 1755 (2000)] we described the basic principles of two-dimensional (2D) optics and showed that a wavelength lambda in three-dimensional (3D) space (x,y,z) may appear in Flatland (x,z) as a wave with another wavelength, lambda = lambda/cosalpha. The tilt angle alpha can be modified by a 3D (Spaceland) individual who then is able to influe...

Induction of general anaesthesia with intraosseous injection of thiopental in rabbits

The technique of intraosseous (IO) infusion has been reemerged as an alternative route of intravascular access for the delivery of fluids and some medications. Complications of IO infusion occur rarely and include fractures and osteomyelitis after long-term use of IO access. The purpose of this study was to compare the efficiency of induction of anaesthesia by a standard intravenous route and a...
