Clinical study of nimodipine on large area cerebral infarction of severe traumatic brain injury after operation

Objective To investigate the clinical effect of early application of nimodipine on a large area cerebral infarction after severe traumatic brain injury operation.Methods Fifty-one patients with severe head injury after large area cerebral infarction were as treatment group who hospitalized from January 2009 to January 2012,and 48 hospitalized cases as the control group from January 2005 to January 2008.The patients in control group were received drugs to decrease intracranial pressure,and enhance nerve nutrition therapy,while in the treatment group,beside the therapy method of control group,were received nimodipine intravenously by micro-pump for 10 days,and then oral administration for 10 days.Plasma endothelin-1 was detected at 0,5th,7th,14th day days after hospitalization.Dopple was pplied to record the middle cerebral artery (MCA) peak systolic velocity(Vp) of the injured side for 7 d.Glasgow outcome score(GOS) was recorded in the 3 months follow-up.The awakening time was recorded consciousness.Results At 21 st day after treatment,22 cases were died in the treatment group and survival patients with cerebral vasospasm were 14 cases (48.28％,14/29).However,30 cases were died in control group and cerebral vasospasm(CVS) of survival patients was 15 cases (83.33％,15/18),significantly higher than that in treatment group (x2 =5.78,P ＜ 0.05).The variable tendencies of Vp,plasma endothelin-1 and the intracranial pressure were significantly different between the treatment group and the control group (Vp:F group =276.27,Ftime =603.54,F interactive =85.68 ; plasma endothelin-1:F grouP =281.16,F time =608.32,F interactive =87.45 ; intracranial pressure:F grouP =326.58,F time =78.63,F interactive =27.39 ; P ＜ 0.05).Mter 3 months of treatment,the value of GOS was significandy higher in treatment group than that of control group (x2 =4.76,P ＜ 0.05).Furthermore through three months treatment,the effective rate in treatment group was higher than that in the control group (52.94％ (27/51) vs.(31.25％ (15/48)),the awakening periods was shorter than that in control group((20.7 ±6.5) d vs.(27.8 ± 7.6) d,t =3.19,P ＜ 0.05)).Conclusion Early applications of nimodipine treatment after severe traumatic brain injury patients with massive cerebral infarction can significantly improve the clinical efficacy and shorten the duration of coma.
