Monitoring Regional Oxygen Saturation - Casecag.com

Continuous monitoring of cerebral oxygen saturation in elderlypatients undergoing major abdominal surgery minimizes brainexposure to potential hypoxia.Casati A, Fanelli G, Pietropaoli P, et al.Study Design:• Multicenter, prospective, blinded,randomized and controlled trial of 122elderly, high risk general surgery (majorabdominal) patients– Subjects were expected >2 hour operationand were >65 YOAHypothesis:• rSO 2 monitoring with active interventionduring cerebral desaturations in elderlypatients undergoing major abdominalsurgery will reduce the potential exposureof the brain to inadequate oxygen supplyConclusion:• Cerebral desaturations were common(~20% of patients) during major abdominalsurgery in the elderly and reacting to theseevents prevented exposure of the brain topotential hypoxia. Effective treatment ofthese cerebral desaturations resulted indecreased PACU and Hospital LOS, lesscognitive decline (as assessed by MMSEscores)Anesth Analg. 2005;101(3):740-747
