We describe a combined gas-chromatographic mass-spectrometric method for determination of theophylline in whole blood. With use of a probability-based matching approach, the extensive gas-chromatographic interference did not affect mass-spectrometric quantitation of theophylline. Concentrations expected and found were linearly related from 1 to 60 mg/liter; the run-to-run coefficient of variati...

Monitoring of ethanol concentration in expired air is a method for assessing fluid absorption during transurethral prostatic surgery and endometrial resection, but the validity of this technique has not been studied in low-flow ventilation systems. For this purpose, we have compared the concentration-time profiles of ethanol in expired gas and in venous blood during an i.v. infusion of 0.4 g kg...

Arterial blood gases (ABG), a clinical test that involves measurement of the pH of arterial blood and the amount of oxygen and carbon dioxide dissolved in arterial blood, is routinely used in the diagnosis and monitoring of predominantly critically/acutely ill patients being cared for in hospital emergency rooms and intensive care units. The test allows assessment of two related physiological f...

conclusions we have demonstrated that ibgms, while not reaching statistical significance, may be associated with slightly reduced a1c and cost due to visiting physicians. results there is a trend of lowered total cost in the intervention group compared to the control group. the control group spent $210.89 per year on visits to physicians; the intervention group spent $131.26 (p = 0.128). patien...

background: people who use home blood glucose monitors may use their mobile phones in the close vicinity of medical devices. this study is aimed at investigating the effect of the signal strength of 900 mhz gsm mobile phones on the accuracy of home blood glucose monitors. methods: sixty non-diabetic volunteer individuals aged 21 - 28 years participated in this study. blood samples were analyzed...

Mesenteric ischemia can complicate acute aortic dissection. We report a case of acute type A aortic dissection with perioperative intestinal ischemia, which clinically manifested on the second postoperative day. Serial monitoring of serum lactate level by a conventional blood gas analyzer was useful for early diagnosis and for timely treatment of intestinal ischemia. In this report, monitoring ...
