心肺复苏初期徒手胸外按压与机械胸外按压对患者血气指标、预后影响

Effects of bare-handed chest compression and mechanical chest compression on blood gas parameters and prognosis of patients during the initial stage of cardiopulmonary resuscitation

目的比较心肺复苏初期徒手胸外按压与机械胸外按压对患者血气指标以及预后的影响。方法选择我院2016年9月～2017年11月接收的64例心跳呼吸骤停患者,将其根据心肺复苏方法不同平均分组,每组32例,对照组患者接受徒手胸外按压,研究组患者则接受机械胸外按压,对两组患者血气指标、预后等进行分析。结果两组间pH值、乳酸、PaCO_2以及PaO_2等血气指标方面差异较小(P>0.05);在心肺复苏成功率方面,对照组与研究组分别是59.37%和84.37%,研究组明显高于对照组,差异有统计学意义(P<0.05);对照组与研究组患者不良反应发生率分别是31.25%和9.38%,差异有统计学意义(P<0.05)。结论机械胸外按压与徒手胸外按压均不会影响患者pH值、乳酸、PaCO_2以及PaO_2等血气指标,但是机械胸外按压心肺复苏成功率要比徒手胸外按压更优,除此之外,其能够降低患者气胸、胸壁胸内脏器损伤以及肋骨骨折等不良反应发生率,值得普遍采纳和推广。

Objective To compare the effects of chest compression and mechanical chest compression on blood gas parameters and prognosis of patients during the initial stage of cardiopulmonary resuscitation. Methods 64 research subjects were all the patients with heartbeat and respiratory arrest who were admitted to our hospital from September 2016 to November 2017. According to the different methods of cardiopulmonary resuscitation, the patients were evenly divided into groups, with 32 patients in each group. Patients in the control group were given bare-handed chest compression, and patients in the study group were given mechanical chest compression. The blood gas indexes and prognosis of the two groups were analyzed. Results The differences in blood gas indexes such as PH value, lactic acid, PaCO2 and PaO2 between the groups were small, and the statistical significance was not established（P〉0.05）; in the success rate of cardiopulmonary resuscitation, the control group and study group were 59.37% and 84.37% respectively. The study group was significantly higher than the control group, and the difference was statistically significant（P〈0.05）; the incidence rate of adverse reactions in the control group and the study group was 31.25% and 9.38% respectively, and the difference was statistically significant（P〈0.05）. Conclusion Mechanical chest compression and bare-handed chest compression will not affect the blood gas parameters such as pH value, lactic acid, PaCO2 and PaO2. However, the success rate of mechanical chest compression on cardiopulmonary resuscitation is better than that of bare-handed chest compression. In addition, it can reduce the incidence rates of adverse reactions such as pneumothorax, chest internal wall organ damage, and rib fractures in the patients, and therefore it is worthy of widespread adoption and promotion.
