摘要
目的探讨手动杠杆式胸外按压心肺复苏(CPR)装置对院内心肺复苏按压质量和复苏疲劳的影响。方法将12名医学生志愿者分为手动杠杆式胸外按压CPR装置组(LDCPR)(n=6)和徒手标准CPR组(STCPR)(n=6)模拟院内心肺复苏场景进行CPR试验。LDCPR组采用手动杠杆式胸外按压CPR装置对模拟人进行连续6min连续胸外按压,STCPR组徒手对模拟人进行6min连续胸外按压。监测复苏期间按压的深度、频率以及按压者的心率和疲劳程度等变化。结果随着连续胸外按压的进行,按压者的心率和疲劳程度都在不断增加,有效按压深度超过5 cm次数逐渐减少,但是在连续胸外按压的第4~6min,LDCPR组按压者的心率较STCPR组慢(P<0.05),疲劳程度较轻(P<0.05),有效按压的比例更高(P<0.05)。按压频率两组比较无明显差异。结论在本模拟人试验中,手动杠杆式胸外按压CPR装置可减轻按压者疲劳,有助于提高院内CPR时长时间胸外按压的质量。
Objective We aimed to investigate simulated in-hospital cardiopulmonary resuscitation(CPR)quality and rescuer fatigue of external chest compression-only CPR by a manual leverage device(LDCPR).Methods All 12 vol-unteers(medical staffs:male 6 and female 6)were randomized to standard CPR by hand(STCPR)group(n=6)or LD-CPR group(n=6).At STCPR group,continuous external chest compression-only was performed for6 minutes to simulate in hospital cardiopulmonary resuscitation on a manikin;at LDCPR group,compression-only was performed for 6 minutes by a le-verage device on a manikin.We measured blood pressure of the volunteers before and after performing each CPR technique,volunteers self-report fatigue scale and continuously monitored heart rate(HR)of the volunteers during each CPR technique by smart ring.CPR quality measures included chest compression rate and depth.Results During continuous external chest compression-only CPR,compressor’s heart rate and fatigue scale were rising continuously,and percent of compress depth〉5 cm were declining,too.Compressor’s heart rate and fatigue scale were higher in the STCPR group than in the LDCPR group(P〈0.05)during the fourth to sixth minutes CPR(P〈0.05).Percent of compress depth〉5 cm was higher in the LD-CPR group than in the STCPR group(P〈0.05)during the fourth to sixth minutes of CPR(P〈0.05).Compress rate had not differed between the 2 groups during CPR.Conclusion In the manikin study,manual leverage external chest com-press device may reduce fatigue scale and improve long term compression quality during in-hospital cardiopulmonary resus-citation.
