Critical Care 1997 1 79 http c CRITICAL CARE RESEARCH Open Access Prehospital point of care testing of blood gases and electrolytes an evaluation of IRMA Gerhard Prause Beatrice Ratzenhofer-Komenda Anton Offner Peter Lauda Henrika Voit Horst Pojer Abstract Background This study evaluated the feasibility of blood gas analysis and electrolyte measurements during emergency transport prior to hospital admission. Results A portable battery-powered blood analyzer was used on patients in life threatening conditions to determine pH pCO2 pO2 sodium potassium and ionized calcium. Arterial blood was used for blood gas analysis and electrolyte measurements. Venous blood was used for electrolyte measurement alone. During the observation period of 4 months 32 analyses were attempted on 25 patients. Eleven measurements 34 could not be performed due to technical failure. Overall 25 samples taken from 21 patients were evaluated. The emergency physicians all anesthesiologists considered the knowledge of blood gases and or electrolytes to be helpful in 72 of cases. This knowledge led to immediate therapeutic consequences in 52 of all cases. After a short training and familiarization session the handling of the device was found to be problem free. Conclusions We concluded that knowledge of the patients pH pCO2 and pO2 in life threatening situations yields more objective information about oxygenation carbon dioxide and acid-base regulation than pulse oximetry and or capnometry alone. Additionally it enables physicians to correct severe hypokalemia or hypocalcemia in cases of cardiac failure or malignant arrhythmia. blood analysis emergency prehospital care Introduction Oxygenation and ventilation are important factors in the treatment of emergency patients. A number of studies have shown that the severity of hypoxemia is frequently underestimated even by experienced emergency physicians. With noninvasive methods such as pulse oximetry and capnometry the .
