Die Herzpunktion bei der Ratte zur wiederholten Blutentnahme und Injektion
1971
Cardiopunkture in anesthesia is a rapid and accurate method for withdrawal of blood and injection without as many complications as suspected if carried out correctly. In the animal placed on its back a syringe with a gauge-24 needle is inserted in the left 4th or 5th intercostal space close to the sternum. When the needle is slowly pushed forward toward the spine continuous suction is exerted with the plunger. After blood has been drawn the needle is removed with a quick jerk. Thus when rats were punctured 8 to 18 times only 1 animal died of a hemopericard in 275 punctures. No other complication could be observed.
Designing of microcontroller based Syringe Pump with variable and low delivery rates for the administration of small volumes
2015
Delivering medications and fluids intravenously is a common practice in modern medical procedures. Administering medications or fluids directly into a patient's blood circulation results in a predictable and immediate absorption of the drug or fluid administered, this may play a vital role in the treatment of certain acute conditions which require immediate action by drugs or fluids. Syringe Pumps are highly useful in delivering a precise quantity of the substance at specific periods of time as required. This research presents a proposal to create a cost effective working prototype of syringe pump for variable and low delivery rates for the administration of small volumes. The presented Syr…
Microbial contamination of anesthetic syringes in relation to different handling habits.
2015
This single-center study prospectively assessed the microbial contamination of anesthetic syringes handled perioperatively under different conditions. We documented high rates of bacterial contamination, with strong but statistically nonsignificant differences between handling groups. Our results identify skin contact as the main source of contamination, and thus we emphasize the impact of proper hand hygiene.
Cartridge syringe vs computer controlled local anesthetic delivery system: Pain related behaviour over two sequential visits - a randomized controlle…
2015
Background: Local anesthetic injection is one of the most anxiety provoking procedure in dentistry. Knowledge about change in pain related behaviour during consecutive visits helps in and scheduling of treatment procedures and management of children in dental clinic. Aim: To compare the pain perception, behavioural response and the associated change in physiological parameters while receiving local anesthesia injection with cartridge syringe and computer controlled local anesthetic delivery system (CCLAD) over two consecutive visits. Material and Methods: In this randomized controlled cross over trial, 120 children aged 7 – 11 years were randomly divided into group A: receiving injections w…
Media-fill simulation tests in manual and robotic aseptic preparation of injection solutions in syringes
2014
Objective The purpose of this study was to evaluate the contamination rate of media-fill products either prepared automated with a robotic system (APOTECAchemo™) or prepared manually at cytotoxic workbenches in the same cleanroom environment and by experienced operators. Media fills were completed by microbiological environmental control in the critical zones and used to validate the cleaning and disinfection procedures of the robotic system. Methods The aseptic preparation of patient individual ready-to-use injection solutions was simulated by using double concentrated tryptic soy broth as growth medium, water for injection and plastic syringes as primary packaging materials. Media fills w…
