Hyperglycemia is common event in critical unit including patients with or without history of diabetes . in patients with septic shock , blood glucose level easily elevated by complex of pathophysiological mechanisms , we investigate the effect of normalization of blood glucose  in septic shock patients including the morbidity , the mortality, the length of icu stay and the time on mechanical ventilation We included 60 patients divided into two groups.Group1:consist of 30 patients was applied to intensive glycemic control. Group 2: consist of 30 patients was applied to conventional glycemic control. We found that strict normalization of blood glucose have favourable outcome than conventional control in morbidity but not mortality. 20 % in group 1 needed hemodialysis and 80 % of patients required hemodialysis in group 2  which is statistically highly significant.  Mortality rate  60% in group 1 and 80% in group 2 which is statistically insignificant. We found that intensive glycemic control have more favourable effects on patient morbidity but have no effect on mortality The misuse of antibiotic and the co-morbidities have direct negative effect in the response to medication and the progression of the disease Hypoglycemia is noticed more in intensive study.
