A study on the relation between hyperglycemia in surgical critical patients and prognosis / 肠外与肠内营养

Objective: To study the relation between hyperglycemia and mechanical ventilatory time, the days in the intensive care unit,infection rate,mortality . Methods: 572 patients' blood glucose levels in the morning were measured,and divided into two groups by the level of 7.78 mmol/L.The mechanical ventilatory time, days in the intensive care unit,infection rate and mortality were compared between two groups. Results: The mechanical time,stay in ICU and infection rate in the group with blood glucose level below 7.78 mmol/L were significantly less than in the group with blood glucose level above 7.78 mmol/L(P
