Predisposing factors for hypoglycemia: security measures for critical patients on intravenous insulin/ Fatores predisponentes para hipoglicemia: aumentando a seguranca do paciente critico que utiliza insulina intravenosa/ Factores predisponentes para hipoglucemia: aumentando la seguridad del paciente critico que utiliza la insulina intravenosa

Documentary, retrospective cross research aiming at describing the predisposing factors studied in critically ill patients receiving continuous insulin infusion. Tracking was made of five hundred and fifty (550) medical records for the years 2012 and 2013 of post-operative cardiac surgery patients who received intravenous insulin. Main results show that nearly half of the patients had at least one record of hypoglycemia, the majority were male (60.11%), elderly (md = 61.78), overweight (26,75Kg / m2), hypertense (78.57%), and ischemic (52.38%). Predisposing factors for hypoglycemia, with statistical significance identified among patients were as follows: diabetes (OR = 3.6); renal failure (OR = 5.4); and use of vasoactive amines (OR = 3.1). Conclusions identified security actions for patients in those conditions such as venous blood collection as well as the use of blood meters to assess glycemic levels.
