目的 探讨急性高原肺水肿患者动态血压的特点。方法 应用美国Spacelabs 90 2 0 7型动态血压记录仪 ,测定 37例急性高原肺水肿患者 2 4h动态血压与正常参照值比较。结果 急性高原肺水肿患者 2 4h动态血压整体水平较正常参照值无明显差异 (P >0 0 5 ) ,收缩压夜间较白昼下降4 3% ,有非常显著性差异 (P <0 0 1) ;舒张压夜间较白昼下降 4 4% ,有显著性差异 (P <0 0 5 )。有 30例患者的动态血压曲线呈非杓型改变。结论 急性高原肺水肿患者 2 4h动态血压整体水平较正常人无明显改变 ,但血压昼夜节律消失。
Objective To investigate the characteristics of ambulatory blood pressure in patients with acute altitude pulmonary edema. Methods US Spacelabs 90 2 0 7 ambulatory blood pressure recorder was used to measure the dynamic blood pressure at 24 hours in 37 patients with acute altitude pulmonary edema compared with the normal reference value. Results The overall level of ambulatory blood pressure at 24 hours after acute altitude sickness had no significant difference (P> 0.05), systolic blood pressure decreased by 43.3% at daytime, and there was a significant difference (P <0.01). The diastolic blood pressure decreased by 44% at night compared with daytime, there was a significant difference (P <0.05). In 30 patients, the ambulatory blood pressure curve showed non-dipper changes. Conclusion The overall level of ambulatory blood pressure at 24 hours after acute altitude pulmonary edema has no obvious change compared with that of normal people, but the circadian rhythm of blood pressure disappears.
