Objective To observe the feasibility of phase-rectified signal averaging applied for the evaluation of automatic nervous system activity in general anesthesia.Methods Forty-seven fe-males and 63 males aged 18-65 years,ASA falling into category Ⅰ or Ⅱ,scheduled for oral maxillo-facial surgery under general anesthesia were selected.The heart rate variability(HRV)signal was re-corded by Powerlab throughout the operation,and then it was sectioned into three segments with 5 minutes:pre-anesthesia(T0 ),means the waking state before the operation;intra-anesthesia(T1 ),the period of operation in 25-30 min;post-anesthesia(T2 ),the consciousness recovery state in the end of the operation.All indicators of HRV analysis was calculated in the time domain.SpO 2 ,MAP and BIS were recorded synchronously in the three periods.Results Compared with T0 ,DC, RMSSD, SDNN,SD1,SD2,logTP,logLF,logHF were significantly lower at T1 and T2 (P <0.05).In con-trast to T1 ,HR,MAP and BIS were significantly higher at T2 (P <0.05 ),DC,RMSSD,SDNN, SD1,SD2,logTP,logLF,logHF were significantly increased at T2 (P <0.05 ).There was positive relation between DC and RMSSD,SD1,logHF (r =0.905,0.909,0.932,respectively,P <0.01). Conclusion As 5 min-DC could indicate the character of PRSA,especially its specificity in showing vagus nerves activities,it is feasible that DC is used to observe the autonomic nerve activity intra op-eration.

Cardiac stroke is a stroke that occurs when a heart mural thrombus falls off and embolizes in the cerebral arterial system caused by various causes of heart disease, accounting for about 30% of all ischemic strokes. At present, in order to find evidence that emboli may originate from the heart, a large number of auxiliary examinations are needed. Good blood biomarkers are essential for the rapid identification of ischemic stroke in the emergency department. However, there is no breakthrough in this area. Brain natriuretic peptide is secreted in ventricular muscle and hypothalamus. It may be an important bridge between brain and heart diseases. However, the application of brain natriuretic peptide in the diagnosis and treatment of cardiogenic stroke is still very limited. This article reviews the current research status of brain natriuretic peptide levels and cardiogenic stroke and proposes further research trends and prospects.
