Impact of balloon mask on effect of prehospital first aid of patients with cardiac arrest
Objective To investigate the impact of balloon mask on effect of prehospital first aid of patients with cardiac arrest.Methods 50 patients with cardiac arrest were divided into a control group and an observation group according to random numerical table,with 25 cases in each group.The control group underwent tracheal intubation in prehospital first aid,while the observation group underwent tracheal intubation combined with balloon mask in prehospital first aid.Comparison was made on treatment effect,prognosis,cardiac function[left ventricular ejection fraction(LVEF),ratio of early diastolic peak flow velocity of mitral valve to late diastolic peak flow velocity of mitral valve(E/A)]at different time points,blood gas index[arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2),pH]before and after resuscitation and satisfaction between the two groups.Results The observation group had airway opening time of(13.04±2.80)s,respiratory recovery time of(112.10±18.80)min,heart beat recovery time of(6.38±1.45)min,and consciousness improvement time of(44.94±9.55)min,which were shorter than(81.88±9.58)s,(158.53±24.08)min,(9.98±2.08)min,and(65.89±12.35)min in the control group,with significant statistical differences(P<0.05).At 6 h after successful cardiopulmonary resuscitation,LVEF and E/A in both groups were higher than those at admission,and LVEF and E/A in the observation group were higher than those in the control group,and there were significant statistical differences(P<0.05).At 1 h after successful cardiopulmonary resuscitation,LVEF and E/A of the observation group were significantly higher than those of this group at admission and the control group,and there were significant statistical differences(P<0.05).There was no statistically significant difference in the control group at 1 h after successful cardiopulmonary resuscitation and at admission(P>0.05).At 6 h after successful cardiopulmonary resuscitation,LVEF and E/A in both groups were higher than those in this group at 1 h after successful cardiopulmonary resuscitation,and there were significant statistical differences(P<0.05).At 30 min after resuscitation,both groups had higher levels of PaO2 and pH than those before resuscitation,while PaCO2 was lower than that before resuscitation;the observation group had PaO2 of(92.21±7.23)mm Hg(1 mm Hg=0.133 kPa)and pH of(7.22±0.15),which were higher than(85.87±8.38)mm Hg and(7.13±0.09)in the control group,and PaCO2 of(44.92±6.30)mm Hg was lower than(53.18±7.81)mm Hg in the control group;there were significant statistical differences(P<0.05).The total satisfaction rate of the observation group was 88.00%,which was higher than the control group's 64.00%,and there was a significant statistical difference(P<0.05).The success rate of treatment in the observation group was 92.00%,which was higher than 64.00%in the control group,and there was a significant statistical difference(P<0.05).Conclusion The combination of balloon mask and tracheal intubation in pre-hospital first aid of patients with cardiac arrest can improve the treatment effect,reduce the cardiac function injury,improve blood gas index,increase patient satisfaction and improve the prognosis.
