Abstract:

Monitoring and evaluating hemodynamic parameters is important nursing initiatives. Changes in physiological functions are reflected on basic vital signs. Therefore, deviations from the normal values of vital signs indicate the disruption of homeostasis. The incidence of fever (elevation of core body temperature) ranges between 28-75% in critically ill patients with different causes. Core Body temperature increase from 37 to 39 °C has been found to be followed by a 10-25% increase of oxygen consumption and energy expenditure. Oxygen and energy consumption due to the increase in core body temperature, cortisol and norepinephrine release and its arterial blood pressure, pulse and arterial oxygen saturation values of the change. High core body temperature due to the change in arterial blood pressure, pulse rate and arterial oxygen saturation values, directly affected by these parameters have been reported. At the present time nonpharmacological (peripheral cooling application, conventional water, air and gel-coated cooling beds, intravascular cooling liquid infusion systems and etc) and pharmacological methods (antipyretic agents) are used to reduce fever, but little research related to the effects of these methods on hemodynamic parameters and prevention of fever complication have been performed. Based on this information, assessment of patients condition, accurate and careful measurement and evaluation of vital signs and hemodynamic parameters play an important role in prevention of complications in the treatment of fever.
