title: [The powerlessness psycho-social response in the postoperative period in cardiac surgery patients].
abstract: OBJECTIVE
  To describe powerlessness on postoperative cardiac surgery patients according to frequency, intensity, defining characteristics and to compare powerlessness between valvular surgery patients (VAL) and coronary artery bypass surgery patients (CAB).
  
  
  METHODS
  Powerlessness was defined through the analyses of interviews of 75 patients (60% VAL and 40% CAB).
  
  
  RESULTS
  58.7% patients presented powerlessness. There were not differences according to powerlessness frequency (p = 0.84) and intensity (p = 0.73) between VAL and CAB patients. The defining characteristics most frequent on powerless patients were: "verbal expressions of having no control or influence over situation" (77.3%), "doubts regarding planning future and stating objectives" (75%), "expressions of doubt regarding role performance" (63.6%), and "expressions of dissatisfaction and frustration over inability to perform previous tasks and/or activities" (56.8%).
