title: Perioperative assessment of the patients in intensive care unit.
abstract: OBJECTIVE
  To evaluate the preoperative condition and the surgical procedure of surgical patients in a general intensive care unit of a university hospital, relating them to morbidity and mortality.
  
  
  METHODS
  We studied the medical records of patients undergoing medium and large surgical procedures, admitted to the general intensive care unit. We analyzed: demographic data, clinical records personal history and laboratory tests, both preoperatively and on admission to the intensive care unit, imaging, operative reports, anesthetic reports and antibiotic prophylaxis. After admission, the variables studied were: length of stay, type of nutritional support, use of thromboprophylaxis, mechanical ventilation, description of complications and mortality.
  
  
  RESULTS
  We analyzed 130 medical records. Mortality was 23.8% (31 patients), Apache II greater than 40 was observed in 57 patients undergoing major surgery (64%), ASA classification e" II was observed in 16 patients who died (51.6%), the length of stay in the intensive care unit ranged from one to nine days and was observed in 70 patients undergoing major surgery (78.5%), the use of mechanical ventilation for up to five days was observed in 36 patients (27.7%), hypertension was observed in 47 patients (47.4%), the most frequent complication was sepsis.
  
  
  CONCLUSIONS
  the correct stratification of surgical patient determines their early discharge and reduced exposure to random risk.
