BACKGROUND The purpose of this study was to compare cardiopulmonary resuscitation (CPR) for simulated maternal cardiac arrest rendered during transport to the operating room with that rendered while stationary in the labor room. We hypothesized that the quality of CPR would deteriorate during transport. METHODS Twenty-six teams composed of 2 providers (obstetricians, nurses, or anesthesiologi...

OBJECTIVES To evaluate the stability of complete blood count (CBC) parameters by measuring at multiple time points up to 72 h after venepuncture. METHODS 36 samples submitted for routine haematology were measured at 0, 8, 24, 48, 72 h. 18 samples were kept at room temperature (23-25 °C) and the other 18 at 4 °C. The stability of the CBC parameters was determined by comparing the results to th...

There is a wide range of mechanisms that can be used to pay for hospital care. In the United Kingdom, hospitals have historically been paid a fixed budget based on the previous years’ costs and activity, sometimes adjusted for planned changes in services (Raftery et al 1996). During the first internal market in the 1990s, purchasers mostly used block contracts – a negotiated amount that was pai...

OBJECTIVE To understand the human factor as a threat to the security of trauma patients in the operating room, bringing to the operating room some important rules already applied in the field of aviation. METHODS The sample included 50 cases of surgical trauma patients prospectively collected by observers in shifts of 12 hours, for six months in a Level I trauma center in the United States of...

Cryopreservation of specimens taken from the genital tract of women is important for studying mucosal immunity during HIV prevention trials. However, it is unclear whether the current, empirically developed cryopreservation procedures for peripheral blood cells are also ideal for genital specimens. The optimal cryopreservation protocol depends on the cryobiological features of the cells. Thus, ...

We have studied the magnetic reversal and thermal stability of [Co(0.3 nm)/Pd(0.7 nm)]N multilayers patterned into 35-nm-diameter nanodot arrays. The short-time coercive fields are relatively constant with N while the room-temperature thermal stability parameter increases nearly linearly with N. However the magnetic switching volume extracted from the thermal stability is significantly less tha...

I n the past 50 years, computers have shrunk from room-size main-frames to lightweight handhelds. This fantastic miniaturization is primarily the result of high-volume nanoscale manufacturing. While this technology has predominantly been applied to logic and memory , it's now being used to create advanced microelectromechanical systems using both top-down and bottom up processes. One possible o...

The occurrence of postoperative pulmonary complications is strongly associated with increased hospital mortality and prolonged postoperative hospital stays. Although protective lung ventilation is commonly used in the intensive care unit, low tidal volume ventilation in the operating room is not a routine strategy. Low tidal volume ventilation, moderate positive end-expiratory pressure, and rep...

Metallic manganese nitrides Mn3AN (A 1⁄4 Zn, Ga, etc) are well-known for their large magnetovolume effect (MVE), i.e., a discontinuous volume expansion at the magnetic transition. However, MVE is exceptionally absent in Mn3CuN. We found that MVE is recovered by a small amount of Ge in the Cu site. This revival seems to coincide with recovery of the cubic structure. By further Ge doping, the vol...
