胰岛素强化治疗对严重创伤患者炎性反应及预后的影响

Objective To investigate the effects of intensive insulin therapy on inflammatory re-sponse and prognosis of patients with severe trauma. Methods Eighty severely injured patients were di-vided 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-α, C-reactive protein (CRP), IL-2, and IL-10 in plasma were assayed. Results High fever appeared in 9 patients in IT group, and WBC exceeded 10.0×109 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 pa-tients 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-α 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-α ( 1.3±0.6 μg/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±0.8μg/L, 89±20 mg/L, respectively, P <0.01 ). Conclusions Intensive insulin therapy can mitigate systemic inflammatory response and improve prognosis of patients with severe trauma.
