[Daily survey of procedures as markers of resources utilization].

OBJECTIVE: To assess and to follow along the time-span of ICU stay the process of resources allocation and utilization. DESIGN: Prospective study. PATIENTS: A cohort of 778 patients consecutively admitted to 7 multipurpose general ICU in the Milano area were enrolled in a survey of the daily performed interventions/procedures. MEASUREMENTS AND MAIN RESULTS: The majority of diagnostic procedure/interventions were performed during the first two days. The number and quality of interventions were transferred into points obtaining a score system in non-monetary units. The resource allocation process shows a regular trend in the sub-intensive patients who were only monitorized. On the contrary the 258 patients who were intensively treated and survived show a phase of high resource-consumption (about 30 daily points: roughly twice the score of monitorized patients) then followed by a post-intensive phase with a resource consumption resulting in a daily score absolutely equal to the sub-intensive patients. The intensive patients who die show a significantly higher score than survived patients. Both daily and cumulative scores do not show differences among different type of patients. CONCLUSION: The evaluation of the process of resources allocation, even if in non-monetary units enables the knowledge of the trend of ICU costs and allows the elaboration of the appropriate budget mechanism.

Cardiac and circulatory response to the intravenous administration of urapidil during general anaesthesia.

The authors have assessed the hypotensive response to the intravenous administration of urapidil bolus, during intra-operative hypertensive crises, in 42 patients undergoing general anaesthesia for surgery. Twenty-two of these patients underwent major vascular surgery and were monitored through catheters introduced into the radial and pulmonary arteries, to study the haemodynamic changes induced by urapidil. A significant reduction was observed in these values: systolic and diastolic arterial pressure, systolic and diastolic pulmonary pressure, pulmonary wedge pressure and systemic vascular resistance. A non-significant reduction was observed in central venous pressure and pulmonary vascular resistance. Heart rate and cardiac output remained unchanged. Systolic arterial pressure decreased 12% from the baseline in 81% of patients. The transient action of urapidil bolus in some cases (55%) suggests the need for urapidil infusion.

[Electroencephalographic changes during anesthesia with low-dose propofol].

The electroencephalographic changes of 12 patients submitted to anaesthesia with low dosages of propofol (4-2 mg/kg/h + fentanyl) for peripheral vascular surgery have been studied. The standard induction dose of propofol was 2 mg/kg for all the patients. The EEG recording was carried out during the whole length of anaesthesia and the EEG changes were analysed during induction and maintenance phases. During surgical anaesthesia it was always easy to read EEG and also to detect eventual cerebral suffering. On the basis of our results we can suggest this anesthesiologic technique for surgery (for example: carotid surgery) requiring a continuous monitoring of the cerebral function during intra and postoperative phases.
