Problem with Portex ‘loss of resistance’ syringes

Loss of resistance technique for locating the epidural space: evaluation of glass and plastic syringes.

Location of the epidural space in epidural anaesthesia usually involves the measurement of loss of resistance using glass or plastic syringes. In the present study two varieties of glass syringe and one plastic type were evaluated to determine the resistive forces associated with plunger movement. The mean static (fs) and dynamic (fd) forces for polished glass syringes having a ground plunger o...

این رساله به مساله احتجاب الهی و مشکلات برهان مبتنی بر این مساله میپردازد. مساله احتجاب الهی مساله ای به قدمت ادیان است که به طور خاصی در مورد ادیان ابراهیمی اهمیت پیدا میکند. در ادیان ابراهیمی با توجه به تعالی خداوند و در عین حال خالقیت و حضور او و سخن گفتن و ارتباط شهودی او با بعضی از انسانهای ساکن زمین مساله ای پدید میاید با پرسشهایی از قبیل اینکه چرا ارتباط مستقیم ویا حداقل ارتباط وافی به ب...

Use of SoloShot autodestruct syringes compared with disposable syringes, in a national immunization campaign in Indonesia.

Autodestruct syringes can reduce the improper reuse of syringes, which present a significant risk in the transmission of bloodborne pathogens in developing countries, especially during immunization campaigns owing to the high number of injections given per session. SoloShot is an autodestruct syringe, distributed by UNICEF, which has been shown to be safer and easier to use than standard syring...

The Sterilization of Hypodermic Syringes

Syringes and syringomyelia.

The earliest description of cavities in the cord is generally ascribed to Charles Estienne (1504–c.1564) in La dissection des parties du corps humain... Paris, 1546. But the fi rst use of the term ‘syringomyelia’ was probably that of Charles P. Oliviers d’Anger in De la moelle épinière et ses maladies in 1824; in a later two-volume work he described: ‘Syringomyélie ou cavité centrale dans la mo...
