The continuous measurement of arterial oxygen saturation using pulse oximetry (SpO2) has become popular for critically ill hospitalized patients. Its use in the ambulance transfer of similarly ill patients has been infrequently documented. This study examines the use of prehospital pulse oximetry, with special reference to the ability of ambulance attendants to recognize hypoxemia. ⋯ Hypoxemia, defined as SpO2 of less than 90% for more than 1 minute, was detected in 14 patients. Attendants recognized hypoxemia on clinical grounds in only 4 patients (sensitivity = 28%). Forty-one (82%) patients received various amounts of supplemental oxygen; many patients remained hypoxemic despite therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

To determine the outcome of renal transplant recipients in an intensive care unit (ICU). ⋯ The ICU mortality of renal transplant recipients was twice that of general surgical ICU patients. The hospital mortality rate for recipients admitted immediately postoperatively to the ICU (group 1) was less than predicted by APACHE II.

Existing scoring systems have failed to reflect the pathophysiological changes during ICU therapy, and do not provide reliable criteria for the prediction of outcome in surgical patients. The aim of the present project was to establish a comprehensive scoring system for daily evaluation of physiological parameters and therapeutic interventions in a surgical intensive care unit, and to identify score patterns in the course of ICU treatment to be used for prospective clinical decisions. In a prospective study of 123 consecutive patients who required intensive care for more than two consecutive days we documented 10 physiological parameters and a set of 14 therapeutic interventions on a daily basis over a total of 1274 days. ⋯ At that point, HDWS was superior to APACHE II with respect to the predictive power as assessed by receiver operator characteristic curves. No patient who fulfilled all four unfavorable HDWS-patterns during the first week of ICU treatment survived (but these were only two patients). We conclude that the limited power of scores obtained on admission to predict outcome in surgical patients may be improved by trend analysis of scores over time which also take into account the patients' response to therapy.(ABSTRACT TRUNCATED AT 250 WORDS)
