Comparison of the effect of two different ways of cardiopulmonary resuscitation during cardiac arrest

Abstract

Objective To compare the effect of two different types of cardiopulmonary resuscitation(CPR) in cardiac arrest. Methods 150 patients with cardiac arrest were selected.The patients were divided into two groups according to the random number table method, each group in 75cases.The patients in the control group were treated with CPR.The patients in the observation group were treated with CPR machine.The body temperature, hemoglobin concentration, hematocrit, arterial blood gas analysis and resuscitation were compared between the two groups after 10min and 30min. Results There were no statistically significant differences in body temperature, hemoglobin and hematocrit between the control group and the observation group at 10min and 30min after CPR (t10min=1.44, 2.01, 1.23, t30min=1.69, 1.81, 1.02, all P>0.05). There were no statistically significant differences in PaCO2 between the two groups at 10 min and 30 min after resuscitation (t=1.54, 1.02, all P>0.05). The arterial blood pH[(7.02±0.14)], PaO2[(16.29±4.38)kPa], HCO3- [(5.66±1.73)kPa]and SaO2[(0.84±0.05)%]of the control group recovered 30 min were significantly lower than recovered 10 min (t=7.14, 6.55, 6.20, 7.03, all P<0.05). The arterial blood pH[(7.11±0.1)], PaO2[(18.36±4.55)kPa], HCO3- [(6.34±2.15)kPa], SaO2[(0.86±0.04)%]of the observation group recovered 30 min were significantly lower than recovered 10 min (t=6.75, 6.21, 6.01, 6.60, all P<0.05). The arterial blood pH, PaO2, HCO3- and SaO2 of the observation group were significantly higher than those in the control group at 10 min and 30 min, the differences were statistically significant (t10min=6.03, 7.34, 7.88, 6.10, t30min=6.21, 8.20, 7.10, 6.11, all P<0.05). The effective rate of CPR in the observation group was 69.33%, which was significantly higher than 46.67% in the control group, the difference was statistically significant (χ2=9.34, P<0.05). Conclusion Compared with artificial heart and lung resuscitation, CPR machine is more effective for patients with heartbeat respiratory arrest.It is more effective in cycling support and can improve the efficacy of CPR and is worthy of clinical application.
