Abstract:
Objective To discuss significance of continuous monitoring of jugular venous oxygen saturation(S_(jv)O_2)in the course of mild hypothermia treatment(MHT)for severe traumatic brain injury (sTBI).Methods Intracranial pressure(ICP),S_(jv)O_2 and brain tissue pressure(P_(bt)O_2)were contin- uously monitored in 36 cases with sTBI for analyzing the correlation between S_(jv)O_2 and P_(bt)O_2.Results (1)There was negative linear correlation between P_(bt)O_2 and ICP(r=-0.978,P＜0.05),negative lin- ear correlation between S_(jv)O_2 and ICP(r=-0.947,P＜0.05)and positive linear correlation between P_(bt)O_2 and S_(jv)O_2(r=0.965,P＜0.05)within 24 hours and at 36 hours and 48 hours after injury.(2) The cases with decreased S_(jv)O_2 value had a worse outcome than those with normal S_(jv)O_2.meanwhile,the cases with abnormal increase of S_(jv)O_2 value had worse prognosis.Prognnsis was improved significantly with increase of S_(jv)O_2 in certain range(P＜0.05).Conclusion Continuous monitoring of S_(jv)O_2 can reflect the condition of hemicerebral oxygen metabolism and guide treatment and predicting outcome.
