To characterise the plasma cortisol profile and adreno-cortial responsiveness (short Synacthen test) of patients in septic shock. Retrospective assessment using case-notes and ICU charts. University teaching hospital ICU. 68 septic shock patients with plasma cortisol and/or short Synacthen test measured at ICU-admission or onset of shock post ICU-admission.(More)
To compare the efficacy and safety of intravenous (IV) amiodarone and procainamide for the treatment of atrial tachyarrhythmias (AT) in the critically ill. In this prospective study, patients were allocated to drug treatment on the basis of hospital identification number, even for procainamide and odd for amiodarone. Patients were recruited from a teaching(More)
The ability of various proxy cost measures, including therapeutic activity scores (TISS and Omega) and cumulative daily severity of illness scores, to predict individual ICU patient costs was assessed in a prospective "ground-up" utilization costing study over a six month period in 1991. Daily activity (TISS and Omega scores) and utilization in consecutive(More)
OBJECTIVE To characterize the acute actions and physiologic dose profile of epinephrine, as a single inotrope, in patients with septic shock. DESIGN Prospective clinical study. The relationship between epinephrine dose and cardiovascular variables was analyzed using repeated-measures analysis of variance. SETTING ICU in a university teaching hospital.(More)
BACKGROUND Generalized linear models (GLMs) have recently been introduced into cost data analysis. GLMs, transformations of the linear regression model, are characterized by a particular response distribution from one of the exponential family of distributions and monotonic link function which relates the response mean to a scale on which additive model(More)
Pilot evaluation of the clinical use of transcutaneous aortovelography has been undertaken and suggests that this technique will be useful in the assessment of left ventricular function in the acutely ill patient. Changes in waveform as a result of therapy or alteration in clinical condition can frequently be noted by critical visual assessment. Increasing(More)
OBJECTIVE Accurate measurement of temperature is vital in the intensive care setting. A prospective trial was performed to compare the accuracy of tympanic, urinary, and axillary temperatures with that of pulmonary artery (PA) core temperature measurements. DESIGN A total of 110 patients were enrolled in a prospective observational cohort study. SETTING(More)
A continuous high flow CPAP system incorporating a turbine blower is described. The system achieves inspiratory flow rates of 150l/min or more by means of reticulated gas flow and inspired oxygen fractions of 0.21–0.95. Positive airway pressure is provided by weighted disc valves and a modified aviationtype CPAP face mask provides electronic communication(More)
