Purpose. Little attention has been given to syringe design and local anaesthetic administration methods. A microprocessor-controlled anaesthetic delivery device has become available that may minimize discomfort during injection. The purpose of this study was to document the pain experience associated with the use of this system and to compare it with use of a conventional syringe. Methods. A pr...

This prospective, nonblinded study, comparing jet injection with needle-syringe injection of lidocaine in performing digital blocks, tested the hypothesis that jet injection can be used effectively as a less painful way to perform digital blocks. Twenty-four adult patients with injuries of the middle or distal phalanges of the fingers received digital blocks using a jet injector on one side of ...

OBJECTIVE For optimal imaging in first-pass radionuclide angiography (FPRNA) studies, 1.11 GBq (30 mCi) 99mTc-sestamibi doses are drawn up in volumes of 0.1-0.3 mL. A single bolus injection of this small volume is important to obtain accurate time-activity curves. Because of the small volume and concentrated radioactivity, it is undesirable for study effectiveness and image quality to have a si...

It explains 'what nature "does" as vell as how she "looks."' Presentinig a well balanced synthesis of the entire field of ecology, the textbook combines the funtctional and the descriptive, the aquatic and terrestrial,...

A syringe device for the injection and evacuation of highly viscous silicone oil was developed. The problem of removing the air interfering with these manoeuvres was solved by providing special outlets in the plunger and handle of a conventional glass syringe. A slightly modified commercial motor perfusor was chosen to power this device, which has proved to be good and fail-safe in more than 10...

OBJECTIVE To compare the effectiveness and convenience of a pen device for the self-administration of follitropin β with a conventional syringe delivering follitropin β solution in patients undergoing IVF-ET. METHODS GnRH agonist long protocol was used for controlled ovarian stimulation (COS) in all subjects. A total of 100 patients were randomized into the pen device group or the conventiona...

OBJECTIVES This study sought to assess relations of laws prohibiting over-the-counter syringe sales (anti-OTC laws) to population prevalence of injection drug users and HIV prevalence or incidence among 96 US metropolitan areas. METHODS A cross-sectional analysis was used. RESULTS Metropolitan areas with anti-OTC laws had a higher mean HIV prevalence (13.8% vs 6.7%) than other metropolitan ...

INTRODUCTION AND AIMS Thailand's longstanding HIV epidemic among injection drug users (IDU) has been attributed, in part, to the Thai government's unwillingness to implement evidence-based HIV prevention interventions. This study was undertaken to examine risk factors for syringe borrowing among a community-recruited sample of Thai IDU. DESIGN AND METHODS We examined the prevalence of syringe...

Injection drug users (IDUs) account for more than 60% of all new hepatitis C virus (HCV) infections in the United States. Fifty to eighty percent of new IDUs are infected within 6 to 12 months of initial injection. Current treatment regimens are not highly effective, and no vaccine against HCV is available. Studies suggest that drug treatment and syringe exchange programs may play a role in red...
