title: Secondary polycythemia does not increase the risk of perioperative hemorrhagic or thrombotic complications.
abstract: OBJECTIVE
  To determine the effects of secondary polycythemia on perioperative hemorrhagic and thrombotic complications.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  Surgical patients at a university-affiliated Veterans Administration Hospital.
  
  
  METHODS
  One hundred patients with a diagnosis of chronic obstructive pulmonary disease and a preoperative hemoglobin concentration (Hb) greater than 16 g/dl and 100 age-, sex-, operation-, and ASA physical status-matched control patients without secondary polycythemia having operations during January to June 1988.
  
  
  RESULTS
  Anesthetic and perioperative records were retrospectively analyzed for excessive bleeding and transfusion requirements. Charts also were retrospectively analyzed for the presence of hemorrhagic and thrombotic complications for 30 days following surgery. The secondary polycythemic patients were compared with the matched control group and did not have a higher frequency of these complications. Red blood cell transfusion requirements for patients with secondary polycythemia were less than that for the matched controls (p less than 0.005). There was no statistical difference for transfusions of other types of blood products such as platelets and fresh frozen plasma (FFP).
  
  
  CONCLUSIONS
  Secondary polycythemia does not impart any added perioperative risk.
