Abstract:
OBJECTIVETo investigate the effects of intensive insulin therapy on inflammatory response and prognosis of patients with severe trauma.
METHODSEighty severely injured patients were divided into intensive insulin therapy group (n = 40, IT) and routine therapy group (n = 40, RT) in random pair. At the time of admission, a continuous infusion of insulin (2-4 U/h) was pumped into the patients of IT group to maintain blood glucose level at 6-8 mmol/L. Patients in RT group were given routine treatment without administration of insulin. Fever, organ injury, and mortality of patients in 2 groups were recorded. Venous blood was drawn from patients of 2 groups on the morning of post treatment day (PTD) 1, 3, 5, and 7. Values of TNF-alpha, C-reactive protein (CRP), IL-2, and IL-10 in plasma were assayed.
RESULTSHigh fever appeared in 9 patients in IT group, and WBC exceeded 10.0 x 10(9) for more than 3 days in 17 patients in this group, versus 20 and 29 patients respectively in RT group. Dysfunction of 1 organ appeared in 31 patients in IT group and 30 patients in RT group. Dysfunction of 3 organs appeared in 10 patients in IT group and 19 patients in RT group. Dysfunction of 4 organs appeared in 7 patients in IT group and 12 patients in RT group. In IT group, 4 patients died within 3 post-injury day (PID), and 1 patient died after PID 3 (total case fatality: 12.5%). In RT group, 5 patients died within 3 PID, and 4 patient died after PID 3 (total case fatality: 22.5%). Plasma levels of TNF-alpha and CRP of patients in IT group were significantly lower than those of patients in RT group on PID 3-7 ( P < 0.05 or P < 0.01), while levels of IL-2 and IL-10 of patients in IT group were significantly higher than those of patients in RT group (P < 0.05 or P < 0.01). Plasma levels of TNF-alpha (1.3 +/- 0.6 microg/L) and CRP (55 +/- 16 mg/L) of patients in IT group on PTD 7 were lowered to the trough level, and they were significantly lower than those of patients in RT group (3.0 +/- 0.8 microg/L, 89 +/- 20 mg/L, respectively, P < 0.01).
CONCLUSIONSIntensive insulin therapy can mitigate systemic inflammatory response and improve prognosis of patients with severe trauma.
