The admission cardiorespiratory performance in relation to outcome in pediatric ICU patients.
We tested the hypothesis that the admission cardiorespiratory performance determines the outcome in pediatric intensive care unit (PICU) patients. We studied 331 patients who were assigned to one of the three commonly encountered PICU clinical entities: respiratory disease, cardiovascular disease and head trauma. All patients were evaluated by a simple cardiorespiratory scoring system which we named "Rule of 60" (RO60), and their highest score within the first 24 h of arrival in the PICU was used for the study. This scoring system includes 6 cardiorespiratory parameters where a value of 60 represents a cut-off point above or below which 0 points (low risk) or 10 points (high risk) are assigned. The relationship between score and mortality rate revealed that the higher the score the higher is the mortality rate. We determined two categories of severity of illness in our patients. Patients at severity level A had scores ranging from 0 through 30 and the mortality rate in this category ranged from 2% to 5%. Patients at severity level B had scores ranging from 40 through 60 and had a higher mortality rate: 30% to 80%. The overall mortality rates for patients at severity level A and B were 2% and 54% respectively. Patients with respiratory disease at severity level B had the lowest mortality rate (20%), whereas patients with cardiovascular disease and head trauma had mortality rates of 52% and 80% respectively. We found that our cardiorespiratory scoring system was as good as the Glasgow Coma Scale for indicating prognosis and outcome in head trauma patients.(ABSTRACT TRUNCATED AT 250 WORDS)
