【摘要】：目的探讨徒手心肺复苏及机械心肺复苏过程中颈动脉血流超声的特点和监测作用。方法选取2015年11月~2016年11月我院急诊科心跳骤停的患者28例作为研究对象,随机分为徒手复苏组和机械复苏组,各14例。徒手复苏组给予患者徒手胸外按压30 min,机械复苏组应用心肺复苏机按压30 min。通过超声多普勒技术测量胸外按压过程中初始5 min和终末5 min颈动脉收缩期血流速度峰值均值(PSV)及每分钟按压频率。结果徒手复苏组初始5 min颈动脉PSV平均值高于终末5 min,差异有统计学意义(P0.01),按压频率达标率高于终末5 min(P0.05)。机械复苏组初始5 min、终末5 min PSV平均值及按压频率达标率分别高于徒手复苏组初始5 min、终末5 min,差异有统计学意义(P0.01),机械复苏组按压达标率为100%。结论机械复苏较徒手心肺复苏可获得较好的颈动脉血流灌注,超声技术对按压频率及颈动脉的血流量可实时反馈,可作为一种无创CPR质量控制的方法。
[Abstract]:Objective to investigate the characteristics and monitoring effect of carotid flow ultrasound in the process of unarmed cardiopulmonary resuscitation and mechanical cardiopulmonary resuscitation.Methods from November 2015 to November 2016, 28 patients with cardiac arrest in the emergency department of our hospital were randomly divided into unarmed resuscitation group and mechanical resuscitation group with 14 cases each.The patients in the bare hand resuscitation group were treated with free hand chest compression for 30 minutes, and the mechanical resuscitation group were treated with cardiopulmonary resuscitation machine for 30 min.The peak systolic velocity of carotid artery (PSV) and the compression frequency per minute were measured by ultrasound Doppler technique during the initial 5 min and the end 5 min of carotid artery systolic velocity.Results the mean value of carotid PSV at 5 min was higher than that at the end of 5 min in the freehand resuscitation group, the difference was statistically significant (P 0.01), and the rate of press frequency reaching the standard was higher than that of the terminal 5 min (P 0.05).In the mechanical resuscitation group, the average value of 5 min PSV at the beginning of the resuscitation group, the average value of 5 min PSV at the end and the rate of reaching the compression frequency were higher than those in the freehand resuscitation group at the beginning 5 min and the end 5 min, respectively. The difference was statistically significant (P 0.01).Conclusion Mechanical resuscitation can obtain better carotid artery perfusion than freehand cardiopulmonary resuscitation. Ultrasound can provide real-time feedback on compression frequency and carotid blood flow. It can be used as a non-invasive CPR quality control method.
