Filter by:This observational study includes patients at medium-to-high cardiovascular risks undergoing major noncardiac surgery, measures their baseline demographic and clinical characteristics, preoperative cardiac biomarkers and intraoperative surgery/anesthesia related data, and screens them for the occurrence of myocardial injury and major adverse cardiac events after surgery. The primary aim is to develop and validate a pre- and an immediate postoperative prediction model for occurrence of major adverse cardiac events.
The current multicenter stepped wedge randomized cluster trial study aims to assess whether implementation of preoperative multidisciplinary team (MDT) discussions is (cost)effective for high risk noncardiac surgical patients. The main questions to answer are: - Primary question: Does implementation of preoperative multidisciplinary team discussions for high risk noncardiac surgical patients diminish serious adverse events as compared to care as usual at six months postoperatively or six months after multidisciplinary team discussion in case of nonsurgical treatment? - Secondary questions: Does implementation of preoperative multidisciplinary team discussion for high risk noncardiac surgical patients improve disability, survival, functional outcome, quality of life and cost-effectiveness as compared to care as usual at six months postoperatively or six months after multidisciplinary team discussion in case of nonsurgical treatment? Participants will be asked to answer questionnaires at baseline, 3, 6,9 and 12 months postoperatively or post MDT discussion. Patients for whom no structured preoperative multidisciplinary discussion is installed yet (care as usual) will be compared with patients for whom a structured preoperative multidisciplinary discussion is performed (intervention). The study will be performed in hospitals that have no established preoperative MDT meeting at the start of the study.
The trial groups will be: 1. Routine fluid management. Clinicians will be blinded to RI monitoring and use clinical judgement to determine how much fluids should be given, and when. Clinical judgement will be according to their standard practice and may include interpretation of blood pressure, and heart rate. 2. RI-guided fluid administration. RI fluid guidance will be initiated before anesthesia induction and will maintain until end of anesthesia. Clinicians will titrate fluids with the goal of keeping RI above 90- always using good clinical judgement for individual patients which may include avoiding fluid when RI is <90 or giving additional fluid when RI >90. For RI scores below 90, 1 cc/kg actual body weight fluid bolus of any crystalloid solution (normal saline or Ringer's lactate) will be given; colloids and blood products can also be given if clinically indicated. The target will be maintained until end of anesthesia. Anesthesia will be maintained for the entire surgical procedure per clinical routine. At the end of the surgical procedure, patients will be extubated and transferred to the post anesthesia care unit (PACU).
This prospective cohort study aims to determine whether the addition of the 6MWT to the RCRI score improves the risk prediction of postoperative cardiovascular outcomes after noncardiac surgery. In addition, this study will assess whether the patients' reported MET score corresponds to the determined MET score from the 6MWT distance completed.
