Modulation of General Anesthesia Using Entropy and Surgical Pleth Index

The critically ill polytrauma patient is one of the most complex cases with regard to the optimization of the intensive care, anesthesia, as well as postoperative management. One of the most important steps in the complex management of such patients is the modulation of anesthesia and the volemic resuscitation, especially in the first hours post-trauma, and in the operating room admission. We start with the assumptions that the optimization of anesthesia should depend on each patient, being conducted in an individual manner. We also believe that by individualizing the anesthesia by monitoring the entropy and SPI it is possible to obtain an appropriate management regarding resuscitation and volume replacement. Furthermore it assumes that an adequate anesthesia, and resuscitation singled volume replacement can reduce morbidity and mortality rates as well as the period of stay in the ICU and recovery time.
