Abstract: Objective To investigate the anesthesia and perioperative blood management of patients with Marfan syndrome (MS) undergoing scoliosis surgery. Methods The clinical data of MS patients underwent scoliosis surgery from January 2013 to December 2015 in Peking Union Medical College Hospital were collected and compared with patients received the same surgery but without MS. Perioperative information and data on anesthesia and blood management were analyzed. Results Compared with control group, MS patients were found with more preoperative comorbidities with statistical significance, including eye disease, echocardiographic abnormalities, and ventilatory defects. MS patients had significantly more blood loss, more intraoperative and postoperative allogeneic and autologous blood transfusion. The operation time, anesthesia time, and length of postoperative hospital stay were all significantly longer in MS patients. Conclusions MS patients are common with multi-system involvement and comorbidities. Considering the high risk of perioperative bleeding, the anesthesia and blood management for MS patients undergoing scoliosis surgery should be with extra caution. Blood management should be applied and appropriate invasive monitoring methods should be considered when necessary.
