Dangerous Anaesthetic Device

Oxygen fail-safe device for an anaesthetic apparatus.

There are circumstances when the oxygen supply to an anaesthetic apparatus can fail. If this is not noticed immediately, the patient becomes anoxic. Many of the oxygen failure warning devices available at the present time only give a visual or audible signal of the failure and they rely on a second gas supply (usually nitrous oxide) and/or batteries for their operation (Falkner Hill, 1956; Hosp...

Carbon dioxide rebreathing with the anaesthetic conserving device, AnaConDa®.

BACKGROUND The anaesthetic conserving device (ACD) AnaConDa(®) was developed to allow the reduced use of inhaled agents by conserving exhaled agent and allowing rebreathing. Elevated has been observed in patients when using this ACD, despite tidal volume compensation for the larger apparatus dead space. The aim of the present study was to determine whether CO(2), like inhaled anaesthetics, adso...

Health worker exposure risk during inhalation sedation with sevoflurane using the (AnaConDa®) anaesthetic conserving device.

INTRODUCTION AND OBJECTIVE Occupational exposure to sevoflurane should not exceed 2 ppm. During inhalation sedation with sevoflurane using the anaesthetic conserving device (AnaConDa(®)) in the post-anaesthesia care unit, waste gases can be reduced by gas extraction systems or scavenging devices such as CONTRAfluran™. However, the efficacy of these methods has not been clearly established. To d...

Dangerous liaisons

Cells during mitosis and meiosis undergo chromosome condensation through a process that depends on evolutionary conserved large protein complexes known as condensins. There are two condensing complexes, condensin i and ii, each of which is composed of five subunits. Condensin i and ii play essential, yet distinct, roles in chromosome condensation and segregation during mitosis. Recent findings ...
