Brief summary
Crude incidence rate in Spain of hip fracture in people over 65 years was 511 cases per 100,000 in 2002. About 30% of patients die in the first year. Cardiocirculatory complications during and after surgery partly explain this high morbidity and mortality. Most patients are frail and with multicomorbidity. Goal-Directed Hemodynamic Therapy (GDT) based on noninvasive continuous monitoring of blood pressure, heart rate, oxygen saturation, cardiac output, cardiac index, stroke volume and stroke volume index can reduce perioperative complications and improve survival. The objective of our study is to assess the efficacy of a goal-directed hemodynamic therapy in reducing perioperative complications. Patients and Methods: non-randomized intervention study with a historical control and 1-year follow-up. Patients older than 64 years with non-traumatic hip fracture requiring surgical intervention. In the control group standard care was performed based on non-invasive, intermittent arterial pressure measurement, obtained every 5 minutes, continuous heart rate, and oxygen saturation. In the intervention group GDT based on noninvasive monitoring will be performed. The main outcome will be the percentage of patients with perioperative complications. Secondary outcomes: LOS and survival at 12 months of surgery.
Interventions
Before entering the operating room, hemodynamic optimization start by optimizing preload with Fluid Challenge according to evidence-based GDT protocols. Once stabilized the cardiovascular system after induction of anesthesia, hemodynamic optimization continue with Mini Fluid Challenge. In the intraoperative period, hemodynamic optimization is based on maintaining systolic blood pressure and stroke volume. A Mini Fluid Challenge is administered to patients who respond to volume or a vasoactive drug according cardiac index for non-responders.
Hemodynamic control is held by non-invasive continuous monitoring techniques (system ClearSight® and Platform EV Clinic 1000®). Monitored variables: blood pressure, heart rate, oxygen saturation, cardiac output, cardiac index, stroke volume and stroke volume index.
