对 12例中枢性发热 (A组 )和 2 8例不伴中枢性发热 (B组 )的急性脑出血患者及 2 0例正常对照组 (C组 )进行心率变异性 (HRV)分析 ,结果显示 :(1)A、B两组的HRV均较C组显著下降 ,表明急性脑出血后的交感神经和迷走神经活性降低 ,植物神经功能受损。 (2 )A组HRV较B组显著下降 ,提示伴发热的急性脑出血患者植物神经功能受损更严重。这可能是急性脑出血中枢性发热的机制之一 ,对急性脑出血的定位、临床治疗、预后、以及与感染性发热的鉴别均有良好的指导意义。
Heart rate variability (HRV) analysis was performed in 12 patients with central fever (group A) and 28 with no central fever (group B) and 20 normal controls (group C) (1) The HRVs of A and B groups decreased significantly compared with that of C group, which showed that the activity of sympathetic and vagal nerves decreased and the autonomic function was impaired after acute intracerebral hemorrhage. (2) The HRV of group A was significantly lower than that of group B, which implied that autonomic dysfunction was more serious in patients with fever and acute cerebral hemorrhage. This may be one of the mechanisms of central cerebral hemorrhage in acute cerebral hemorrhage. It has a good guiding significance for the location of acute cerebral hemorrhage, clinical treatment, prognosis, and identification of infectious fever.
