Forced-air-warming (FAW) is an effective and widely used means for maintaining surgical normothermia, but FAW also has the potential to generate and mobilize airborne contamination in the operating room.We measured the emission of viable and non-viable forms of airborne contamination from an arbitrary selection of FAW blowers (n=25) in the operating room. A laser particle counter measured parti...

The current trend in anaesthesia is to choose crystalloid over colloid fluids for volume replacement in the operating room. Outcome-oriented studies and kinetic analyses have recently provided more insight into how crystalloid infusions should be managed. These fluids have a much better short-term effect on the plasma volume than previously believed. Their efficiency (i.e. the plasma volume exp...

effect of sucrose replacement with date syrup powder on physiochemical properties of sponge cake such as specific gravity, volume, apparent density, solid density, porosity, symmetry, moisture content, water activity, crust color and textural firmness was studied. batter specific gravity of the control sample was higher than that of other samples. sucrose replacement with 100% of date syrup pow...

UNLABELLED We previously studied hospitals in the United States of America that are losing money despite limiting the hours that operating room (OR) staff are available to care for patients undergoing elective surgery. These hospitals routinely keep utilization relatively high to maximize revenue. We tested, using discrete-event computer simulation, whether increasing patient volume while being...

The production of 11C, 13N, 15O from C, N, O, and of 39Cl and 41Ar from Ar by a p(66)Be(49) clinical neutron therapy beam has been measured. The results of these measurements were used to estimate the production of other radionuclides, then to estimate airborne radioactivity in a typical neutron therapy room and radioactivity induced in body tissues during treatment. Only under special circumst...

Understanding the behavior of airflow in a room is essential for building designers to provide the most efficient design of ventilation system, and having acceptable indoor air quality. This trend is the motive to solve the relationship between airflow parameters and thermal comfort. This paper investigates airflow characteristics, indoor air quality (IAQ), and the thermal comfort (TC) in a ven...

UNLABELLED In response to U.S. Pharmacopeia general chapter <797> standards, a clean room was constructed for our in-house radiopharmacy. Previously, most patient doses were prepared as needed just before injection. Currently, to minimize repeated entries into the clean room, most patient doses are prepared in batches; that is, early morning and noontime preparation of doses to be injected at v...
