■直升机紧急医疗服务(HEMS)在美国和全球范围内用于应对危重病患者和外伤受害者。在美国,相对有限的研究已经检查了它们在应对院外心脏骤停(OHCA)中的作用。在这项研究中,我们比较了HEMS治疗的OHCA与地面救护车治疗的心脏骤停.
■我们查询了美国紧急医疗服务(EMS)激活(NEMSIS)的大型国家级数据库。纳入标准为2022年1月1日至2022年12月31日期间由HEMS或地面救护车治疗的OHCA激活。然后比较两组的关键逮捕数据。EMS到达后的设施间转移和心脏骤停被排除。
■HEMS治疗的1,233例心脏骤停和地面救护车治疗的341,096例心脏骤停符合纳入标准。比较两组,有HEMS反应的心脏骤停更可能是男性(66.7%vs.62.8%,p<0.01),白色(50.2%与45.7%,p<0.01),18岁以下(10.9%vs.2.7%,p<0.001),与创伤性损伤相关(19.1%vs.5.7%,p<0.001),见证(72.7%与37.3%,p<0.001),并且最初可电击(24.7%与11.1%,p<0.001)。
■我们对HEMS治疗的心脏骤停与地面救护车治疗的心脏骤停的比较揭示了两组之间的显着差异。随着非创伤性和创伤性心脏骤停新的院前复苏技术的发展,需要进一步的研究来更好地描述HEMS在OHCA反应中的理想作用。
UNASSIGNED: Helicopter emergency medical services (HEMS) are used in the United States and globally to respond to patients with critical illness and victims of traumatic injury. Relatively limited research has examined their role in responding to out-of-hospital cardiac arrests (OHCA) in the United States. In this study, we compared OHCA treated by HEMS units with cardiac arrests treated by ground ambulances.
UNASSIGNED: We queried a large national-level database of emergency medical services (EMS) activations in the United States (NEMSIS). Inclusion criteria were OHCA activations between January 1, 2022 and December 31, 2022 treated by either HEMS or ground ambulance. Key arrest data from both groups were then compared. Interfacility transfers and cardiac arrests after EMS arrival were excluded.
UNASSIGNED: A total of 1,233 cardiac arrests treated by HEMS and 341,096 cardiac arrests treated by ground ambulances met inclusion criteria. Comparing the two groups, cardiac arrests with HEMS response were more likely to be male (66.7% vs. 62.8%, p < 0.01), White (50.2% vs. 45.7%, p < 0.01), under 18 years old (10.9% vs. 2.7%, p < 0.001), associated with traumatic injury (19.1% vs. 5.7%, p < 0.001), witnessed (72.7% vs. 37.3%, p < 0.001), and initially-shockable (24.7% vs. 11.1%, p < 0.001).
UNASSIGNED: Our comparison of cardiac arrests treated by HEMS with cardiac arrests treated by ground ambulance reveals significant differences between the two groups. Further research is needed to better characterize HEMS\' ideal role in the response to OHCA as new prehospital resuscitative techniques for non-traumatic and traumatic cardiac arrest are developed.
