Abstract:
Objective To explore the clinical significance of dynamic determination of serum procalcitonin(PCT)levels in judgment of infection and prognosis in patients with severe craniocerebral injury.Methods A total of 80 patients with severe craniocerebral injury were selected and they were divided into infection group and non-infection group.Infection group was divided into improved group and non-improved group.Acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and Glasgow coma scale(GCS)score was compared between infection group and non-infection group.The level of serum PCT,white blood cell count(WBC),C-reactive protein(CRP)and interleukin(IL)-6 was compared on the first,third,fifth day of admission in intensive care unit among these groups.Results Infection group in 48 patients,and non-infection group in 32 patients.There was no significant difference in age,sex and GCS score between two groups(P ＞0.05).APACHE Ⅱ score in infection group was higher than that in non-infection group [(21.71 ± 7.13)scores vs.(15.32 ± 6.17)scores],and there was significant difference (P＜ 0.05).The level of serum PCT on the first day of admission in intensive care unit in infection group was higher than that in non-infection group[(2.15 ± 1.79)ng/L vs.(0.56 ± 0.47)ng/L],and there was significant difference(P＜ 0.05).There was no significant difference in WBC,CRP and IL-6 between two groups(P＞0.05).The level of serum PCT,WBC,CRP,IL-6 on the third day of admission in intensive care unit in infection group was higher than that in non-infection group,and there was significant difference(P＜ 0.05).The level of serum PCT on the fifth day of admission in intensive care unit in infection group was higher than that in non-infection group [(3.09 ± 1.98)ng/L vs.(1.06 ± 0.63)ng/L],and there was significant difference (P＜0.05).WBC,CRP,IL-6 on the fifth day of admission in intensive care unit was(15.13 ±6.32)×109/L,(103.56 ±40.62)mg/L,(230.41 ± 121.83)ng/L in improved group(38 cases),and (18.62 ±8.89)× 109/L,(134.38 ± 34.16)mg/L,(268.73 ± 138.12)ng/L in non-improved group(10 cases),and there were significant differences between two groups(P ＜ 0.05).The level of serum PCT on the first,third,fifth day of admission in intensive care unit in improved group was lower than that in non-improved group,and there was significant difference(P ＜ 0.05).Conclusion The alteration of serum PCT level may be used as one of the effective predictors for infection in patients with severe craniocerebral injury and for their prognosis.
